Basics About CNC Machining POM

Polyoxymethylene homopolymer (POM) is a semi-crystalline thermoplastic known for its impact resistance and wear resistance, widely used in various mechanical machining applications. The CNC delrin is favored by engineers due to its excellent material properties and high machinability. Although inherently opaque, CNC 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. The machining delrin 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.

Properties	Descriptions
Electrical Properties	POM exhibits excellent insulation properties, combined with its exceptional mechanical strength, making it an ideal material for electronic components. CNC 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 Strength	POM 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 delrin machined parts that need to withstand high pressure.
Fatigue Resistance	POM 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 Resistance	POM can withstand instantaneous impact without failure, primarily due to its high toughness. Specially treated POM can offer even greater impact resistance.
Dimensional Stability	Dimensional stability measures a material's ability to maintain its normal dimensions after exposure to pressure, temperature, and other conditions during processing. CNC machining delrin does not deform during machining processes and is suitable for achieving precise tolerances.
Friction Characteristics	Moving mechanical components typically require lubrication to reduce friction between them. POM machined delrin 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.
Sturdiness	POM'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 Resistance	Even in highly humid conditions, POM absorbs minimal moisture. This means it can maintain its structural integrity even in underwater applications.

Creep Resistance	Machined delrin 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 Insulation	POM 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."

Delrin Machining Tips

CNC POM is easily deformed during CNC machining because the fuse is too low. Control the CNC delrin processing temperature: The melting point of POM is between 165-175°C, so the temperature should be controlled not to exceed this range during processing to avoid overheating of the material. Cause deformation.
Use Sharp Tools: Always use sharp, high-quality cutting tools to minimize friction and heat buildup, which can cause the CNC POM material to deform or melt.
Optimize Cutting Speeds: Maintain moderate machining delrin feeds and speeds to achieve a balance between efficient material removal and surface finish quality.
Coolant Application: Apply coolant or air blasts to dissipate heat and reduce the risk of thermal expansion, ensuring dimensional stability and prolonging tool life.
Clamping and Fixturing: Secure the workpiece properly using appropriate clamping and fixturing techniques to prevent movement and ensure precise machining.
Chip Removal: Ensure effective chip removal to avoid re-cutting of chips, which can damage the surface finish and affect the overall quality of the machined delrin parts.
