High-precision 5-axis CNC machining – Custom parts machining for POM materials

POM is an excellent engineering plastic, renowned for its superior mechanical strength, wear resistance, and dimensional stability. In CNC machining, POM is widely used in precision mechanical parts, gears, bearings, industrial fixtures, and medical devices. Its excellent fatigue resistance and low coefficient of friction make it an ideal metal replacement material, especially for high-precision and high-wear applications.

Product Description 

POM Material Properties

1. Excellent Mechanical Properties
POM has extremely high rigidity and strength. Its tensile strength, impact resistance, and creep resistance make it suitable for high-load environments. During CNC machining, POM maintains stable dimensional accuracy, ensuring precise part dimensions.
2. Superior Wear Resistance and Low Coefficient of Friction
POM’s self-lubricating properties ensure low friction even without additional lubrication, making it suitable for moving parts such as gears and sliders. Its wear resistance far exceeds that of ordinary plastics, extending the service life of the parts.

3. Excellent Chemical Stability
POM has good corrosion resistance to most organic solvents, oils, lubricants, and weak acids and bases, suitable for industries such as chemical, automotive, and food processing. Its wide temperature range (-40°C to 100°C) meets the needs of various working environments.
4. High-Precision Machining Performance
POM is easy to machine with CNC, achieving high precision of ±0.01mm, meeting the machining needs of complex structural parts. Its low moisture absorption ensures dimensional stability after machining, preventing deformation due to humidity changes.

POM CNC Machining Process and Challenges

We use advanced CNC lathes and milling machines, combined with high-rigidity tools and optimized machining parameters, to ensure the high precision and surface quality of POM parts. However, machining POM material still presents some challenges:
Cutting Heat Control: POM has a relatively low melting point (approximately 165°C), so it is necessary to control the cutting speed and cooling method to prevent material softening or deformation.
Tool Selection: It is recommended to use sharp carbide or diamond tools to reduce burrs and improve surface quality. Antistatic Treatment: POM is prone to static electricity, so antistatic measures must be taken during processing to prevent dust accumulation and ensure machining accuracy.

POM CNC Machining

Lightweight Design: Compared to metals, POM is lighter, making it suitable for precision mechanical structures where weight reduction is crucial.
Noise and Vibration Reduction: POM’s damping properties effectively reduce noise and vibration in moving parts.
Cost-Effective: POM raw material costs are low, and CNC machining is efficient, making it ideal for large-scale, customized production.
Environmentally Safe: Compliant with RoHS standards, non-toxic, suitable for medical and food-grade applications.
