Wire cutting is one kind of auxiliry processing in Sibai. It plays an important role on some critical products. For example, for narrow slot or tiny holes, we adopt wire cutting processing to realize.

For below such a narrow slot, it is only 2.8 mm wide and 20.8 mm long. We adopt wire cutting .

In our production, we use Electrical discharge wire cutting to process the slot of the stainless steel spindles. Due the special structure, we are unable to process it by traditional machining, and we have to choose Wire cutting. We have processed many similar spindles with various specifications.

Features of Wire Cut Electric Discharge Machining
Electrical discharge machining wire cutting is a non-traditional machining, which mainly uses electric energy to realize the processing of materials. Electrical discharge wire cutting is not limited by material properties, and can process any hardness, strength, brittle materials. There is no significant mechanical chip force in the processing, regardless of how the hardness and stiffness of the work piece is, as long as the materials are conductive or semi-conductive, it can process. But it can not process non-metallic conductive materials. Electrical discharge wire cutting is widely used in machining production by the advantages of high machining accuracy, high production efficiency, low power consumption and low manufacturing cost.

In the same time, there are two notable disadvantages.

One is, if the workpiece is too thick, it is difficult for working fluid to enter and fill the discharge gap, which will affect machining accuracy and surface roughness.

The other is, in the process of machining, there may be cracks and deformation on the surface of the work pieces. Therefore, before processing, proper heat treatment and rough machining should be carried out to eliminate the defects of material properties and blank shape, to improve the machining accuracy.

Sibai is a professional precision machining manufacturer, we provide wire edm machining services, wire edm stainless steel, edm wire brass, 6 axis wire edm, hot wire edm, large wire edm, precision cnc machining service, etc. For cost of edm wire cutting or more information, please feel free to contact us!

Anodizing(2024年05月14日)

sibai — 2024-05-10T18:08:41+0900

https://www.sibaicnc.com/anodizing/

Sibai produces a large number of Aluminium CNC parts, most of which needs anodizing to be natural, black or other colors to avoid the surface scratches, or natural hurt on the surface.

What's more, some of the parts needs sandblasting before anodizing.

The sandblasting can cover the scratches of machining or handling. Some parts needs hard anodizing, for outdoor environment and for UV resistence.

Sibai has more than 5 anodizing plants as partners in Dongguan and Shenzhen. The partners are professional and full of experience on aluminium anodizing.

Sibai has membrance thickness tester, which can test the thickness of the anodizing layers.

What is Anodizing Service and anodised aluminium is?
Anodized aluminum goods a widely used surface treatment process. It is an electrochemical treatment process for metals or alloys, especially for aluminum workpieces.

The Anodizing process can be divided into anodizing and hard anodizing.
Generally, the metal workpiece is placed in a specific electrolyte, and the anode of the aluminum workpiece forms an oxide film through the action of electric current. The original hardness of aluminum is low, but after anodizing, the surface hardness and wear resistance of aluminum can be improved, and it can play a protective effect.

The anodized workpiece has a fine and smooth texture, and can also be electrolytically colored, which has the functions of insulation and decoration. In special applications, it has specific insulating properties, which can effectively improve the bonding force of the organic coating and improve the adhesion, which is often referred to as the film thickness. The thickness of the anodized film is usually about 5-15um. This process is combined with sandblasting and satin polishing to improve the texture and aesthetics on the workpiece surface.

Different from anodizing, the solution of hard anodizing is generally sulfuric acid and sulfuric acid plus organic acid. In addition, the hard Anodizing process can be achieved by reducing the anodizing temperature or reducing the concentration of sulfuric acid. The thickness of the hard anodizing film is generally 25-150um, and the thickness of the anodizing film is controlled by adjusting the anodizing time, acid concentration and temperature. We can adjust the thickness of the oxide film according to customer needs. The higher the film thickness, the stronger the abrasion resistance.
Sibai adopts surface film thickness meter to test the thickness of anodizing.

Aluminium Profile Extrusion(2024年05月13日)

sibai — 2024-05-10T18:07:18+0900

https://www.sibaicnc.com/aluminium-profile-extrusion/

As an industrial material produced by extrusion process, aluminium door extrusion profile will have some difficulties in designing and opening molds, which will be a great challenge for factory's craftsmanship.

Difficulties In Designing And Opening alum extrusion profiles
The first difficulty lies in the tolerance.
The higher the dimensional tolerance requirements, the higher the difficulty. For example, the normal international standard, the high-precision 0.2 tolerance, if the tolerance is increased to 0.1 mm, then the difficulty is even more than doubled.

The second difficulty lies in the cavity.
The more the cavity of the aluminum frame extrusion profiles, the denser and smaller. Then the punch of the die is more likely to be broken during extrusion. A few aluminium extrusion heat sink profiles have not been made, and the mold is broken. The complex and multi-cavity mold reflects the strength level of the factory. Not necessarily a large mold, the production difficulty is large. There are some large molds with a weight of 5-6 tons, but the difficulty is not high, but it requires a large-tonnage extruder. If the die-casting plant is not equipped with the corresponding machine, it cannot work out the big profile. This is not related to the complexity of the mold.

The third difficulty lies in the wall thickness.
Different sizes of presses and the structure of the aluminum h extrusion profiles will have different wall thicknesses for the profiles. For example, on a 5,000-ton pressure, the wall thickness may reach 0.5. Then on a 50,000-ton press, the wall thickness 0.5 is impossible. If the adjacent wall thicknesses too much gap, it is also a very big challenge for the manufacturer to produce the mold.

5 Axis Machining(2024年05月11日)

sibai — 2024-05-10T18:03:32+0900

https://www.sibaicnc.com/5-axis-machining/

Sibai has both 5 Axis universal machining center (Beijing Jingdiao) and 3+2-type 5 axis manufacturing machines.

Five axis universal CNC machining system is often used for producing products with complex design and multiple curved surfaces, such as impellers, blades, marine propellers, heavy-duty generator rotors, steam turbine rotors, large diesel engine crankshafts, etc. Five axis universal CNC machining system are mainly used in aviation, aerospace, military, scientific research, precision instruments, high-precision medical equipment, etc.

What Are The Advantages Of A 5-axis Machining Center Over 3-axis Machining Center?
A 5-axis machine ensures the best tool cutting status. It improves the cutting conditions , and it makes the cutting tool fully play its cutting performance. By a 5-axis machine, it reduces the times of clamping. It can process 5 surfaces of the workpiece in one clamping, which improves the efficiency and reduces the error caused by multiple tool setting. A 5-axis machine simplifies the technological process, improves the substantial efficiency, and can accelerate the research and development cycle of new products. It is not necessary to use long cutting tools on a 5-axis machining center, in order to avoid interference, which can increase rigidity and cutting value. And it reduces the number of cutting tools. A 5-axis machine can use not the tool tip but the tool side edges during processing. For complex processing technology, a 5-axis machine can simplify the processing process. A 5-axis machine has a higher degree of automation, which is simpler to operate than a 3-axis machine.

3+2 type custom 5 axis machining center
Most of the 5-axis machines Sibai has are 3+2-type 5-axis machines, equipped with deviding head based on 3-axis machine. At present, Sibai has 8 sets of 3+2-type 5-axis machining centers. The system is from Fanuc or Mitsubishi.

What is 3+2 type machining center?
In China's machining fields, many so-called 5 axis machining center for sale are equipped by adding two rotating axes on the basis of 3-axis machining centers. It can achieve the effect of processing multiple faces and curved surfaces. Such a 5-axis machiningcenter is a 3+2 type machining center.

What is the difference between Chinese 3+2 machining center and German 5-axis universal machine center?
The Chinese 3+2 machining center is different from the 5-axis universal machine center imported from Germany, no matter from the operating system or the effect of the universal linkage. Different from the German 5-axis universal machine , which has the RTCP (Rotated Tool Center Point), the domestic 3+2 type 5-axis machining center does not have the performance of RTCP function. Although it cannot compare with the German 5-axis universal machine, China's 3+2-type 5-axis machining center has a low price, but it can achieve high precision within a considerable precision range for most of cost-effective processed products. For majority of non-top-precision industries, China's 3+2-type 5-axis machining center can meet the needs of processing.

So what is the difference between 3-axis, 4-axis and 5-axis (3+2)?
The 3-axis machining center is the most widely used at present. There are 3 axes of X, Y, and Z, that is, 3 directions of left - right, top - down, back - forth. The three-axis machining center can perform only single plane side processing.

The 4-axis machining center has one more rotary axis based on the three-axis. If the axis rotates around the X axis, it is called the A axis; and if it rotates around the Y axis, it is called the B axis. Through rotation, the product can be processed on multiple sides, which greatly improves the processing efficiency. And it reduce the times of clamping, especially the machining of cylindrical parts.
The china five axis machining center adds 2 rotating axes on the basis of 3-axis, and can process any surfaces of the workpiece with one side fixed. That is, in addition to the 3D processing of the vertical bottom surface, it can also process side and oblique side. The machining center 5 axis is a machining center with high technology content and high precision, which is specially used for processing complex curved surfaces, complex geometry parts, with the designs of hollow, or with oblique carving or oblique holes.

There are many 5 axis cnc manufacturers, but we are one of the best choices for you.

Copper Machined Parts(2024年04月17日)

sibai — 2024-04-17T11:57:25+0900

https://www.sibaicnc.com/products/copper-machined-parts/

Copper Machined Parts
Sibai provides strictly quality control in the whole process,ensures Copper CNC precision machining parts, from material to finishing, to packing.

Sibai CNC Machining from Copper Material
Sibai made many cnc copper parts.

Copper is challenging to process due to its high ductility and high cold workability.

As below pictures, the material is E-Cu57 F25, and the sizes are almost 68x28x16 and D24x76.

E-Cu57 F25 corresponds to Chinese T2 pure copper.

Pure Copper is easy to stick to the cutting tool, and is of soft texture. It’s difficult to control the accuracy in processing. because copper is an excellent thermal conductor, it creates more heat than other materials, which increases tool wear over time. During processing, the machining speed cannot be too fast, so that the cutting tool can wear not too fast.

Sibai has years of experience on Copper CNC machining.

In the process of production and processing, the surface of copper parts often appears oxidation, blackening and discoloration. In order to restore the appearance cleanliness and product quality of the copper parts, we often carry out chemical polishing treatment on it. The finishing methods of degreasing, derusting and chemical polishing can solve the problems of oxidation, blackening and discoloration on the surface of the copper parts. And the surface can obtain high brightness and flatness .

Due to the nature of the copper itself, the surface of the copper parts after chemical polishing is exposed to the air, which is prone to reoxidation, blackening and other surface problems. Therefore, the copper parts after polishing needs to be treated immediately for oxidation prevention.

At present, the anti-oxidation treatment processes of copper include passivation, electroplating, painting, etc. After chemical polishing, the surface of copper parts has a certain brightness, and the oxidation prevention treatment process of copper does not affect its surface brightness. Sibai adopts the processing of passivation to prevent oxidation.

There are many precision machining suppliers, but we are one of the best choices for you.

CNC Titanium Machining(2024年04月17日)

sibai — 2024-04-17T11:56:55+0900

https://www.sibaicnc.com/products/cnc-titanium-machining/

Sibai has years of customized Titanium CNC machining experience, such as material TC4, TC2, and can do complex geometry designed titanium cnc machining parts, and control the precision and surface well.

Sibai did many CNC Titanium housings for sensor products. Titanium is very expensive material. Titanium’s characteristics are low density (light in weight) but high strength and corrosion resistance. The Titanium products are mainly used in aircraft, automobiles, medical machinery and other high-tech equipments.

Sibai CNC Machining titanium precision parts Features
Titanium is one of the most difficult materials for CNC machining.

Titanium has an excellent strength but it’s density is only 60% of steel’s. Titanium has a lower elasticity than steel, so it is stiffer and flexure is better. Titanium is also more resistant to corrosion than stainless steel and has low thermal conductivity. These properties mean that titanium creates higher and more concentrated cutting forces during machining. It is easy to vibrate and cause chattering during cutting. Titanium material is also prone to react with the cutting tool material during cutting. In addition, Titanium has poor thermal conductivity, and since the heat is mainly concentrated in the cutting zone, the cutting tools must have high thermal hardness.

Sibai controls the precision and difficulty of production carefully. We often have to separate into more than ten or twenty steps of processings to produce a complex Titanium components. We adopt 3-axis, 5-axis CNC machines to do the rough cutting, adopt CNC lathe to create holes, use milling machines to drill inclined holes, and use flat grinding machines to grind the bottom surface. The finished products we make are precise and elegant. We make smooth surface, without oil stains, scratches and burrs.

Sibai provide hundreds kinds of end caps for LED lighting customers. These end caps are made mostly from EN AW 5052, EN AW 6060, 1.4301 and steel. The Aluminum end caps need to be sandblasted and anodized. We do environmental-friendly zinc plating, based on DIN 50979, such as DIN50979-Fe//ZnFe8//Cn//T2 for steel end cap. The quantity of these end caps are from hundreds to thousands of pieces. Some customer directly sells these end caps in the market after they receive them from us. So, the key of these end caps are finished products and perfect packaging.

Generally speaking, our customers can give us specific packing requirements. For example, we need to pack 2 pcs of end caps and 4 pcs of screws to be 1 set. We will put 2 pcs of end caps into a bigger plastic bag, and 4 pcs of screws into 1 small plastic bag. Then we will put this small plastic bag with screws into the bigger plastic bag. In this way, it can avoid the end cap damaged by screws. Finally, we will put the Label markings on the bigger plastic bags. After that, it is completely finished and perfectly packed.

All these end caps look simple, but the processing is not easy. The most complex and difficult is the anodizing processing. To control the color consistence of the anodizing, we get the original matching profiles from customers. We use the color of these matching profiles to check and control the anodized color of these end caps. If the colors are too much different, all these end caps we have to scrap, or rework. So, we pay more attention to find the right way to control the anodizing color consistence. Now we make anodizing color card to check each batch before delivery. It really helps us a lot to improve the anodizing color consistence.

Now, Sibai can provide these end caps very well. Because of the consistent good quality, perfect packaging and on-time delivery, customers are very satisfied.

Aluminium Panels And Frames(2024年04月17日)

sibai — 2024-04-17T11:54:46+0900

https://www.sibaicnc.com/products/aluminium-panel-frame/

Sibai made a lot of aluminium panel frame for electronic products and instruments, from CNC machining. Sibai does various surface finishing, such as powder coating to different colors.

Sibai Aluminium Panels and Frames Features
Sibai made a lot of Aluminium big panel and frames.

Sibai has been engaged in CNC machining for many years, and has made many panels and frames for aluminum electronic products and instruments. Sibai’s CNC machiningcenters can process up to a size range of 1100 x 600 mm. In addition, Sibai also uses 5-axis (3+2) machines to do the profile processings and curve side processings.

In addition to machining, Sibai does also various required surface treatments for these panels and frames, such as sandblasting + anodizing, laser marking, powder coating etc.

These panels and frames are visible appearance products. Therefore, the surface quality and surface treatment process are very demanding. For example, if a panel with a large appearance area, we need to ensure that there are no scratches on the panel, and meanwhile, when anodizing, we have to ensure the color consistency anywhere on the entire panel. It requires high standard on both CNC machining and surface treatment.

The powder coating

The powder coating is also a very big challenge finishing. Sibai has tried powder coating on aluminum panels many times. The powder coating of each batch is greatly affected by powder quality, powder quantity, temperature, and powder spraying time.

Rapid Galvanization Services
With the development of of science and technology, the galvanization finish is very common to our lives. Galvanization is a popular surface treatment, including electroplating for materials of copper, aluminum, steel, etc.

Galvanization is a process by which a layer of metal film is uniformly attached to metal and other materials by electrolysis. Galvanization is mainly used to increase the wear resistance of the workpiece, prevent corrosion, increase the thickness, and improve the aesthetics of the plated object.

The galvanization process is a process in which the workpiece is placed in the electrolyte, the workpiece is energized as the cathode, the electroplated metal in the container is energized as the anode, and the coating is obtained through chemical reaction. The plating layer after galvanization should be uniform and dense, with a certain thickness, so that the galvanization layer and the surface of the workpiece can be isolated from the air and play a protective role.

Galvanization is divided into rack plating and barrel plating.

Rack plating is to clamp the workpiece on the hanger, which is suitable for workpieces with high precision and strict appearance requirements.

Barrel plating, also known as barrel copper plating, is suitable for smaller workpieces. The small workpiece is placed in the rolling copper, and the coating is deposited on the surface of the workpiece under the rolling state by indirect conduction.

sibai — 2024-01-23T15:00:59+0900

https://www.sibaicnc.com/stepper-motor-precision-machining/

A 2 pole rotor is a motor that converts electrical pulse signals into corresponding angular displacement or linear displacement. Each time a pulse signal is input, the rotor rotates an angle or moves forward one step, the output angular displacement or linear displacement is proportional to the number of input pulses, and the rotational speed is proportional to the pulse frequency. Therefore, stepper motors are also called pulse motors.

Features of Sibai Machining Capabilities in Stepper Motor
Stepping motors are widely used in ATM machines, inkjet printers, cutting plotters, photo machines, spraying equipment, medical instruments and equipment, computer peripherals and mass storage equipment, precision instruments, industrial control systems, office automation, robots and other fields, especially suitable for applications requiring smooth operation, low noise, fast response, long service life and high output torque.

There are many structural forms and classification methods of stepping motors. Generally, they are divided into three types: reluctance motor, permanent magnet motor and mixed magnetic motor, according to the excitation method.

According to the winding on the stator, there are two-phase, three-phase and five-phase serie motors. The most popular is the two-phase hybrid stepping motor, which accounts for more than 97% of the market share. The basic step angle of this type of motor is 1.8°/step. When equipped with a half-step driver, the step angle is reduced to 0.9°. With a subdivision driver, the step angle can be subdivided up to 256 times (0.007°/micro step). Due to friction and manufacturing accuracy, the actual control accuracy is slightly lower. The same stepper motor can be equipped with different subdivided drivers to change the precision and effect.

Titanium Alloy Machining Processes(2023年09月04日)

sibai — 2023-08-15T18:57:34+0900

https://www.sibaicnc.com/machining-titanium-alloy/

Sibai has a lot of experience on producing CNC machining Titanium alloy parts. In recent years, Titanium CNC machining has become a very important part of our work. CNC Titanium alloy occupies 15% of our orders.

Titanium is one of the most difficult machined material, because of it’s 3 high properties, high strength, high hardness, high heat-resistence.

Sibai has gained a lot of experience on machining Titanium by adopting suitable milling tools, and cutting fluid, and by setting up the program in right way, and by adopting various machining ways, such as milling, turning, wire cutting, flat grinding, EDM cutting.

Titanium Alloy Machining Processes Solution
1. Titanium alloy has the characteristics of low thermal conductivity, serious hardening during process, high affinity with tools, and small deformation, which are the essential reasons for the difficulties of processing Titanium alloys.

Its machinability index is only 20% of that of free-cutting steel. The thermal conductivity of titanium alloy is only about 16% of that of C45 steel. The heat cannot be conducted in time during processing, resulting in local high temperature of the cutting edge, which is easy to cause tool diffusion wear. The hardening of titanium alloy is obvious, which causes certain difficulties forr following processing. What’s more, the workpiece is also easy to get clamping move.

Sibai controls above process difficulties by choosing the appropriate milling cut tools for titanium alloy, which can increase the processing strength and improve the surface finish.

2. To choose a cutting tool that can keep sharp continuously, such as a tungsten-cobalt carbide milling cutter or a ceramic milling cutter is a way to control Titanium alloy machining.

When machining, we should reduce the rake angle of the tool appropriately, and dissipate heat by increasing the contact between the cutting and the rake face. Meanwhile, the relief angle of the tool is increased to reduce the tool bonding caused by the frictional contact with the tool flank when the machined surface springs back. It is best to have a rounded corner transition on the tip, so that the tool has rigidity.

3. In processing, we have to lower the processing speed of the CNC machine. This is also a point for Titanium alloy processing.

4.During the processing of Titanium alloy, there is a risk of fire. It is very necessary to place a fire extinguisher beside the machine at any time.

Sibai is a professional titanium machining companies, we provide titanium machining services, precision cnc services, etc. For more information, please feel free to contact us!

https://www.sibaicnc.com/machining-carbon-steel/

Machining high carbon steel, because of lower material costs, they are often adopted as substitudes of stainless steel.

In Sibai we prefer to accept the carbon steel orders in large quantities. Because of lower prices and heavy load, we prefer to do the oceanshipping, instead of airshipping.

Carbon steel is an iron-carbon alloy with a carbon content of 0.0218% to 2.11%. Generally machining carbon steel contains a small amount of silicon, manganese, sulfur, phosphorus. Generally, the higher the carbon content in carbon steel, the greater the hardness and the higher the strength, but the lower the formability.

Carbon steel can be classified as carbon structural steel, high-quality carbon structural steel, carbon tool steel, cast steel, etc.

For different applications, carbon steel can be divided into three categories: carbon structural steel, carbon tool steel and free-cutting structural steel.

Machining Service In Bearings(2023年09月01日)

sibai — 2023-08-15T18:54:40+0900

https://www.sibaicnc.com/machine-bearing/

Bearings are an important component in contemporary machinery and equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Bearings are classified broadly according to the type of operation, the motions allowed, or to the directions of the loads (forces) applied to the parts.

Features of Sibai Machining Capabilities in Bearings
The main purpose of bearings is to prevent direct metal to metal contact between two elements that are in relative motion. This prevents friction, heat generation and ultimately, the wear and tear of parts. It also reduces energy consumption as sliding motion is replaced with low friction rolling.

They also transmit the load of the rotating element to the housing. This load may be radial, axial, or a combination of both. A bearing cnc also restricts freedom of movement of moving parts to predefined directions as discussed above.

However, there are many applications where a more suitable bearing can improve efficiency, accuracy, service intervals, reliability, speed of operation, size, weight, and costs of purchasing and operating machinery.

Thus, there are many machine bearing types, with varying shape, material, lubrication, principle of operation, and so on.

Sibai offered products are precisely engineered using optimum grade metal with the help of cutting-edge techniques in compliance with set industry norms. Moreover, these products are checked for their quality on series of quality parameters before being supplied to our clients assuring their flawlessness at user’s hand.

CNC Machining Titanium Alloys(2023年06月26日)

sibai — 2023-06-19T18:16:15+0900

https://www.sibaicnc.com/cnc-machining-titanium/

What is Titanium alloy?
Titanium is a very expensive alloy.

In comparison, ferroalloy is around the price of 9 RMB/kg; brass is around the price of 50 RMB/kg; which titanium alloy can reach 300 RMB/kg.

The civilian titanium alloy plate is in the range of 150-280 RMB/kg; while the military titanium alloys will be no less than 500 RMB / kg, and even reach 1300 RMB/kg.

CNC Machining Titanium Advantages
Titanium alloys are the nobles of machined metals. Titanium alloy has the characteristics of high strength, good corrosion resistance, high temperature resistance and fatigue resistance. Titanium alloy with the same physique is only 60% of the weight of steel, but stronger than alloy steel. Titanium alloys are mainly used in the development of high-temperature titanium alloys for aero-engines and structural titanium alloys for airframes.

The properties of titanium are related to the content of impurities such as carbon, nitrogen, hydrogen, and oxygen. The purest titanium iodide has an impurity content of no more than 0.1%, but has low strength and high plasticity.

The properties of 99.5% industrial pure titanium are: density ρ=4.5g/cm3, melting point 1725℃, thermal conductivity λ=15.24W/(m.K), tensile strength σb=539MPa, elongation δ=25%, area shrinkage ψ =25%, elastic modulus E=1.078×105MPa, hardness HB195.

The most widely used titanium alloys are Ti-6Al-4V (TC4), Ti-5Al-2.5Sn (TA7) and industrial pure titanium (TA1, TA2 and TA3).

How To Machine Titanium Alloy Effectively?
There are many processing methods for titanium alloys, including: turning, milling, boring, drilling, grinding, tapping, sawing, EDM, etc.

For continuous cutting, mass production or cutting with a large amount of metal removal, tungsten-cobalt carbide tools are generally used.

For forming cutting, grooving or cutting, tempered steel tools or cermet tools can be adopted. Drilling titanium alloys should use a short, sharp drill bit and low-speed force feed. And the brackets should be tightened and repeatedly cooled sufficiently, especially for deep hole drilling.

During the drilling process, the drill bit should be kept in the drilling state in the hole, idling in the hole is not allowed, and the drilling speed should be kept low and constant.

Tapping titanium alloys is probably the most difficult machining operation. Blind holes or long through holes should be avoided as much as possible to prevent the internal thread surface from becoming rougher or taper breaking.

Decades of Experience at Titanium Cnc Service
At Specialized Turning, Sibai is an expert in machining titanium alloys to produce the best possible quality and value.

While each type of titanium has its own intricacies, we match state-of-the-art tooling geometries and coatings to ensure the most economical stock removal rates at the highest speeds possible for economical machining.

How does Sibai choose cnc stainless steel milling cutters?

Due to the high toughness, high thermal strength and low thermal conductivity of stainless steel materials, the deformation during cutting is relatively large, and the hardening during process is serious. The more to cut, the more difficult it is to dissipate heat, resulting in a rapid increase in the temperature of the tool tip, resulting in built-up edge. The built-up edge can easily take away the coating on the tool tip itself, aggravate the wear of the tool, affect the roughness of the tool surface, and also affect the surface quality of the workpiece.

Therefore, it is very critical to correctly select the geometric angle and cutting amount of the tool.

From the past processing work, Sibai summed up the following experience in selecting stainless steel milling cutters:

Cobalt is an very important element for milling tools. Without high-content cobalt, the milling tools are easy to wear off. And the milling tools special for stainless steel must be with special surface coating.

Stainless steel milling tools are classified into 3 categories in terms of materials.

1.Tungsten and cobalt milling cutters, such as YG3, YG6.

2. Tungsten-cobalt-titanium milling cutters, such as YG15, YG30.

3. Generic classes such as YW series.

Generally, YG-types have good toughness and thermal conductivity, and is not easy to stick, and is generally used for rough machining of stainless steel.

While YW-types are relatively good on hardness, wear resistance and heat resistance, oxidation resistance, and toughness, so it is generally used in the finishing of stainless steel.

When processing austenitic stainless steel such as 1Cr16Ni9Ti, it is not suitable to use YT-type, because the titanium in YT-type will have an affinity with the titanium in the workpiece, which will be discharged together with the iron chips, which will speed up the wear of the tool.

What will Sibai consider when purchasing stainless steel raw materials?
There are many stainless steel suppliers in the Chinese market. Some are manufacturers, some are distributors, and some are retail stores. Quality and service capabilities are quite different among them. Therefore, the purchase of stainless steel needs to be very cautious.

When purchasing stainless steel, we must consider the following aspects to avoid purchasing failure. The failure of raw material procurement is not only a failure of raw material itself, but also a failure of machining, a failure of logistics and shipping, a failure of customer imports, a failure of usage and function performance. Therefore, raw material procurement is a source of order success.

In the past 20 years, Sibai has continuously summed up the experience of raw material procurement. Now we summarize the following aspects on stainless steel procurement.

1.Clarifying requests.

When requesting from suppliers, we must get clear the requests, and describe the requirements in details. The requests including grades, specifications, tolerances, specific uses, precautions, and material certificates, we must describe exactly.

2.Selecting big-brand manufacturers.

For large-scale purchases, we are sure to choose big-brand manufacturers. Large manufacturers are important factors to avoid risks. If you choose low prices when purchasing, it is easy to have problems in quality. The big brand manufacturers are more reliable in terms of quality and reputation.

3.Attention to the chemical composition and physical properties of the material.

When purchasing materials, we must ask the supplier to provide material certificates. We pay much attention to the details on the certificates, such as production date and furnace number, etc. When we purchases large quantities, we require suppliers to provide a small piece sample before delivery, and use our spectrum analyzer to inspect the chemical composition of the samples. For example, 304 stainless steel, we need to focus on whether its chromium and nickel compositions meet the 304 standard. The lower than standard on chemical composition will affect the customer's later using function.

4.Attention to the specifications and their tolerances.

Before purchasing raw materials, we must clarify the specifications of the materials. Sufficient allowance should be left for processing. For example, if you buy a bar or tube of a certain outer diameter, you must give the supplier a clear tolerance range. Because if the tolerance range is not clear, it is likely to find that the machining allowance is insufficient after receiving it, which will affect the machining process.

5. When purchasing, it is also necessary to describe the use and processing method of the purchased stainless steel to the supplier. This will help suppliers understand the processing technology and application condition of stainless steel raw materials. Sometimes suppliers will also give reasonable advice to avoid the risks by our own lack of consideration.

6. After the materials are delivered to the warehouse, we must strictly inspect according to the requirements specified in the order. The strict inspections from quality, specification, weight, price and other aspects are necessary to ensure correct incoming materials.

Sibai has accumulated a large number of quality sured and long-term cooperated stainless steel suppliers in the Chinese market. So we can control the risk of purchasing stainless steel and purchase at the most reasonable prices.

Details Of CNC PTFE
Teflon is another name for polytetrafluoroethylene, PTFE.

PTFE cnc machining products are generally referred to as "non-stick coatings". It is a synthetic polymer material that uses fluorine to replace all hydrogen atoms in polyethylene. PTFE is resistant to acid, alkali and various organic solvents. It is almost insoluble in all solvents. PTFE is also resistant to high and low temperatures, up to -180°C to 260°C. Its friction coefficient is extremely low, and the friction with steel can reach 0.04, which is close to rolling friction and can be used for lubrication. PTFE is also one of the most corrosion-resistant materials in the world and can resist any organic solvent. The material is soft, difficult to process, easy to deform, and cannot process high-precision parts. Generally used in mechanical design for wear-resistant parts. Such as chain guides, W-shaped seals, etc. It also makes an ideal coating for the lining of nonstick pans and water pipes.

Some medical customers have requested Sibai to supply medical parts with PTFE raw material. Sibai offers a variety of brackets to medical customers from black PTFE material. These brackets are used in medical equipment. Therefore, the black PTFE material must comply with FDA requirements. SiBai also requires a third-party Lab agency to do raw material testing, and then they can provide FDA certificate reports too. In this way, we can guarantee the quality of PTFE. We use PTFE sheet material for these brackets. The dimensions of these PTFE sheets are 300mm*300mm*8mm. It can withstand high temperature over 134℃. Because these medical customers will do high-temperature sterilization multiple times a day during the use of these brackets.

To be honest, the process of these PTFE stents is not complete, and the processing is also very difficult. But the key is to find suitable and good PTFE raw materials. Appropriate high-quality PTFE raw materials mean high-quality PTFE brackets. Sibai purchased imported PTFE raw materials to ensure the quality of these brackets.

We can also provide machined parts made of PTFE from bars and tubes according to customer needs. Sibai does 100% inspection before delivery. As a result, there are few complaints from medical customers about these components manufactured by Sibai.

Details of CNC POM
POM, namely polyoxymethylene, is a very common engineering plastic material. Usually used for CNC machining, prototyping and injection molding.

Polyoxymethylene is a tough, elastic material with excellent creep resistance, geometric stability and impact resistance even at low temperatures. Polyoxymethylene is available in both homopolymers and copolymers. Homopolymer materials have good tensile strength and fatigue resistance, but are not easy to process. Copolymer materials have good thermal stability, chemical stability and ease of processing. Both homopolymer materials and copolymer materials are crystalline materials that do not readily absorb moisture. The high crystallinity of POM leads to its high shrinkage rate, which can reach 2% to 3.5%. Different reinforcement materials have different shrinkage rates.

POM CNC has a very low coefficient of friction and good geometric stability, and is especially suitable for making gears and bearings. Because of its high temperature resistance, it is also used in pipeline equipment (valve, pump casing), lawn equipment, etc., and audio players such as tape recorders, CD, LD, MD players, radios, headphones, stereos, printers, keyboards, CD-ROMs and other OA machines, washing machines, dryers, hair dryers and other household appliances, seat belt mechanical parts and other auto parts, outdoor door handles , mirrors, computer rooms, precision parts for cameras, clocks, etc., and building materials, toys and stationery such as game consoles, etc.

Nylon CNC Machining

What is nylon CNC Machining Nylon?

Nylon is one of the more non-metallic materials used in non-standard machinery.

Nylon is wear-resistant and self-lubricating, with high geometric accuracy. It can process gear bearings and other parts.

High temperature resistance can reach 160 °C for continuous use. However, it is easy to absorb water and expand when immersed in water, which affects the accuracy.

Sibai makes some white PA 6 and PA66 parts in past orders.

The Common Uses of CNC Nylon Grades

Nylon PA6

Nylon has the most superior comprehensive properties, including mechanical strength, stiffness, toughness, mechanical shock absorption and wear resistance. These properties, combined with good electrical insulation and chemical resistance, make PA6 a "general-purpose" material for making mechanical structural and serviceable components. For the production of mechanical system parts and maintainable parts.

Nylon PA66

Compared with PA6, PA66 mechanical strength, stiffness, heat resistance, abrasion resistance and creep resistance are better, but its impact strength and mechanical shock absorption properties are reduced, so it is very suitable for automatic lathe machining. PA66 is more widely. It is used in products that require impact resistance and high strength, such as the automotive industry and instrument housings.

Nylon PA12

PA12 is Polydodecalactam. Its basic polymerization raw material is butadiene, which can rely on the petrochemical industry. PA12 is a semi-crystalline-crystalline thermoplastic. Its properties are similar to PA11, but the crystal structure is different. PA12 is a good electrical insulating material, and like other polyamides, its insulating properties are not affected by moisture. It has good impact-resistant mechanochemical stability. PA12 has many improved varieties in plasticizing and enhancing properties. Compared with PA6 and PA66, these materials have lower melting point and density, and higher moisture regain.

PA12 is not resistant to strong oxidizing acids. Typical applications of nylon 12 are commercial equipment such as water meters, cable sleeves, mechanical cams, sliding mechanisms, photovoltaic backplanes and bearings, etc.

Copper has good corrosion resistance in the atmosphere, seawater and some non-oxidizing acids (hydrochloric acid, dilute sulfuric acid), alkali, salt solution and various organic acids (acetic acid, citric acid), and is used in the chemical industry.

In addition, copper has good weldability, and can be processed into various semi-finished products and finished products by cold and thermoplastic processing.

Copper is also used in the production of motor short-circuit rings, electromagnetic heating inductors, and high-power electronic components, terminal blocks, etc., and some are also used in furniture and decorations such as doors, windows, and handrails.

Cu-ETP copper welding

Oxyacetylene welding
Wire 201 (or wire 202) welding wire and flux 301 can be used for copper oxyacetylene welding. It is preheated at 400~700℃ before welding, and the welding flame adopts neutral flame and large flame power. With fewer welding layers, hammering the weld after welding reduces welding stress.

Electrode arc welding
Copper electrode arc welding can choose copper 107 or copper 227 electrode. The power supply adopts DC reverse connection. The preheating temperature before welding is 300~500℃, and the short arc, straight line reciprocating transport bar is adopted during welding, and the welding seam is hammered after welding to reduce welding stress.

TIG welding
The welding wire and flux used in argon tungsten arc welding of copper are the same as those used in oxyacetylene welding, and the power source is DC positive connection. Preheat before welding, but the temperature should not be too high.
