High-precision CNC milling & turning for custom POM, Delrin, and Acetal parts. Tight tolerances, zero voids, and fast global delivery. Request a quote today!
POM (Polyacetal, commonly known as Acetal or Delrin®) combines metal-like tensile strength with low friction and outstanding machinability. It is the premier engineering thermoplastic for replacing brass, aluminum, stainless steel, and standard plastics across high-performance applications. We specialize in custom non-standard CNC machining of precision POM components, empowering industries with lightweight, wear-resistant, and cost-effective solutions.
Global POM Material Standards & Grade Cross-Reference
Comprehensive CNC Machining Processes for POM
-
CNC Milling (3, 4 & 5-Axis): Complex 3D geometries, thin-walled enclosures, intricate pockets, and high-precision structural housings.
-
Precision Turning & Turn-Mill Indexing: Single-setup machining for concentric shafts, internal bores, end-grooves, and cross-axis tapping to ensure strict runout tolerances.
-
Micro-Drilling & Custom Threading: Fine-pitch threads, custom pipe fittings (NPT, G, PT), and deep-hole drilling with burr-free edge retention.
-
Stress-Relief Annealing: Pre- and post-machining heat treatments to eliminate internal stresses in thick plates and slender shafts, preventing post-machining warpage.
-
Finishing & Deburring: Ultrasonic cleaning, hand/mechanical precision deburring, mirror polishing, and laser marking.
