Basics About POM CNC Machining
Polyoxymethylene homopolymer (POM) is a semi-crystalline thermoplastic known for its impact resistance and wear resistance, widely used in various mechanical machining applications. It is favored by engineers due to its excellent material properties and high machinability. Although inherently opaque, POM is available in various colors. It has a density of 1.410-1.420 g/cm3, a crystallinity of 75-85%, and a melting point of 175°C. POM is well-suited for machining processes such as milling and turning. It can also be laser cut, and its granules can be used for injection molding and plastic extrusion.

Today, we will primarily discuss the characteristics of this material and the advantages of CNC machining it.
PropertiesDescriptions
Electrical PropertiesPOM exhibits excellent insulation properties, combined with its exceptional mechanical strength, making it an ideal material for electronic components. POM can withstand significant electrical stress, making it suitable for high-voltage insulation. Its low moisture absorption also makes it an excellent material for maintaining dry electronic components.
Mechanical StrengthPOM has a tensile strength of 7000-9000 PSI, is highly rigid, and exhibits exceptional toughness. Additionally, it has a lower density compared to metals, making it suitable for lightweight parts that need to withstand high pressure.
Fatigue ResistancePOM is highly durable and demonstrates excellent fatigue resistance within a temperature range of -40°C to 80°C. Furthermore, its fatigue resistance is minimally affected by moisture, chemicals, or solvents. This characteristic makes it an ideal material for parts subjected to repetitive impacts and stresses.
Impact ResistancePOM can withstand instantaneous impact without failure, primarily due to its high toughness. Specially treated POM can offer even greater impact resistance.
Dimensional StabilityDimensional stability measures a material's ability to maintain its normal dimensions after exposure to pressure, temperature, and other conditions during processing. POM does not deform during machining processes and is suitable for achieving precise tolerances.
Friction CharacteristicsMoving mechanical components typically require lubrication to reduce friction between them. POM machined parts are inherently slippery and do not require lubrication. This feature can be utilized to avoid external lubricators that may contaminate the product's mechanical parts, such as in food processing machines.
SturdinessPOM's high tensile strength and durability make it suitable for high-stress applications. It is highly robust and is often used as an alternative to steel and aluminum alloys.
Moisture ResistanceEven in highly humid conditions, POM absorbs minimal moisture. This means it can maintain its structural integrity even in underwater applications.
Creep ResistancePOM is a highly resilient material that can withstand significant pressure without failure. This excellent durability makes it the preferred material for many industry components.
Electrical InsulationPOM is an excellent insulator, making it suitable for many electronic products.
These fundamental knowledge points and considerations can help you better understand and implement CNC machining of POM materials. Please note that specific machining processes may vary depending on different parts and machine tools, so it is advisable to consult Flourish Legend engineers for machining guidance."

CNC Machining of POM (Delrin/Acetal) Advantages
CNC machining of POM offers several advantages from different perspectives. Here are the four key advantages:

Superior Mechanical Performance
Superior Mechanical Performance: POM exhibits excellent mechanical properties, including high strength, rigidity, and wear resistance. These qualities make POM an ideal choice for manufacturing plastic machined parts and components.

Dimensional Stability and Precision
Dimensional Stability and Precision: POM has a low water absorption rate, allowing it to maintain stable dimensions even in humid environments. This is crucial for applications that require precise dimensions and shapes. CNC machining enables high-precision processes, ensuring accurate dimension control and the creation of complex geometries for optimal product quality and performance.

Chemical Resistance and Heat Resistance
Chemical Resistance and Heat Resistance: POM demonstrates outstanding chemical resistance, making it resistant to various solvents, oils, and fuels. It maintains stable performance in harsh environments. Additionally, POM has good heat resistance, enabling it to maintain mechanical properties at relatively high temperatures, making it suitable for high-temperature applications.

Processing Performance and Efficiency
Processing Performance and Efficiency: POM exhibits good machinability, allowing for easy machining and achieving smooth surfaces and high machining precision. CNC machining, coupled with computer control, enables complex machining paths and shapes, improving production efficiency and precision. CNC machining also enables automated production, enhancing efficiency, consistency, and reducing human errors.
