Custom POM CNC Machining Services
POM combines rigidity, wear resistance, dimensional stability and self-lubricating performance for precision gears, bearings, shafts, sliders and structural parts.
Why Choose POM Material?
POM is a low-friction engineering polymer used as a metal alternative in moving and wear-resistant components. Review its published material properties and self-lubricating behavior when selecting a grade.
Precision and Rigidity
Strong dimensional stability supports accurate gears, boards, shafts and structural components.
Wear and Low Friction
Wear resistance and self-lubrication suit bearings, sliders and other moving parts.
Stable Performance
Low moisture absorption and chemical resistance help maintain consistent dimensions.
Common POM Types and Mechanical Properties
Compare tensile strength, heat deflection and moisture behavior before selecting the grade.
POM-H
StrengthHigh rigidity with 0.20–0.25% published water absorption.
POM-C
GeneralBalanced general-purpose performance with 0.15–0.20% water absorption.
Wear / Rigid POM
WearDesigned for higher wear resistance and rigidity in moving components.
Toughened POM
ImpactHigher impact performance with lower stiffness than standard POM.
Glass-Fiber POM
RigidityHigh strength, stiffness and dimensional stability with low moisture uptake.
Conductive POM
ESDAntistatic or conductive behavior for sensitive electrical applications.
POM CNC Machining Parts and Applications
Original project images include boards, POM connecting rods, precision housings and multi-axis components.




Surface Finishes for POM Parts
POM has low surface energy, so printing and coating require suitable pretreatment and should be confirmed for the application.
As-Machined
Maintains dimensional accuracy, low friction and minor visible tool marks for gears and sliders.
Polishing and Sandblasting
Polishing reduces roughness; sandblasting creates a uniform matte surface on non-sliding areas.
Laser Engraving
Permanent part numbers, logos and serial codes support identification and traceability.
Printing and Coating
Limited printing or functional coatings may be applied after special surface preparation.

Frequently Asked Questions
The original technical guidance is condensed for faster reading.
Which problems commonly occur when CNC machining POM?
Overheating, internal-stress deformation and tool wear are common. Control temperature and cooling, use suitable tooling and avoid excessive depth of cut.
How can POM surface quality be improved?
Use stable roughing and finishing strategies, sharp tools, controlled finishing passes and compatible coolant. Parameters must match tool diameter, geometry and machine conditions.
Why does POM require compatible coolant?
POM can degrade when overheated. Use a compatible coolant that removes heat without introducing chlorine or sulfur contamination; thin walls may use controlled spray cooling.
How are burrs, wrinkles and deformation reduced?
Optimize cooling, replace worn tools, control feed and cutting load, and use compliant fixtures that avoid excessive pressure on thin sections.
How does POM compare with ABS or PA66?
POM generally offers stronger wear resistance than ABS and lower moisture absorption than PA66, supporting stable low-friction components.
