POM is not suitable for metal surface treatments such as anodizing and electroplating.
We machine every material with precision, strictly following its unique properties to ensure the best performance and surface quality. Our team continuously explores and refines the CNC machining strategies for each material, optimizing cutting parameters to achieve greater consistency, accuracy, and efficiency.
| Parameter | Recommended Range | Notes |
| Cutting Tool | Carbide tools preferred | Offers better wear resistance and surface finish |
| Spindle Speed | 6,000 – 12,000 RPM | Moderate speed avoids melting due to low thermal conductivity |
| Feed Rate | 500 – 1,500 mm/min | Adjust based on wall thickness and part complexity |
| Depth of Cut | 0.5 – 2 mm | Shallower passes reduce deformation and maintain accuracy |
| Coolant | Air blast or dry cutting | Coolant often not necessary; use air to remove chips |
| Clamping | Use soft jaws or padding | Avoid deformation due to clamping pressure |
| Toolpath Strategy | High-speed machining | Reduces heat buildup and improves surface quality |
| Finishing Pass | Optional (0.2–0.5 mm) | Improves tolerance and surface smoothness |
| Chip Removal | Required | Prevents chip re-cutting and surface scratches |
POM is easy to machine but may warp if excessive heat builds up.
Ensure sharp tools and avoid tool dwell to maintain dimensional accuracy.
Avoid excessive polishing which could deform thin-wall parts.
REKO offers high-precision CNC machining services for POM (Acetal) components, from rapid prototyping to full-scale production. Our POM parts are widely used in industries such as automotive, electronics, industrial automation, consumer products, and medical equipment — delivering excellent wear resistance, low friction, dimensional stability, and mechanical strength for high-performance plastic applications.
