As a high-quality engineering plastic, CNC POM (polyoxymethylene) is widely used in many industries. Here are some common POM cutting application industries:
CNC machining of POM offers several advantages from different perspectives. Here are the four key advantages:
Superior Mechanical Performance: CNC POM exhibits excellent mechanical delrin machining properties, including high strength, rigidity, and wear resistance. These qualities make POM an ideal choice for manufacturing plastic delrin machined parts and components.
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 including 5 axis 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: POM demonstrates outstanding chemical resistance, making it resistant to various solvents, oils, and fuels. CNC machining delrin 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: 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. Delrin CNC machining also enables automated production, enhancing efficiency, consistency, and reducing human errors.
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." | |
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.
