Machining Method CNC Turning

Precision custom-machined plastic components—including turning covers and bushings—crafted from black/white POM (Acetal) and Nylon, delivering low friction, chemical resistance, and dimensional stability for industrial, automotive, and consumer equipment applications.

Parameter	Key Details
Material	POM (Acetal): Black/white options; low friction coefficient (0.15–0.3), high rigidity, excellent wear resistance, minimal water absorption (ideal for bushings/covers requiring tight dimensional control); Nylon (PA6/PA66): High impact strength, good chemical resistance, self-lubricating properties (suitable for load-bearing bushings and durable covers); all RoHS/REACH compliant
Processing	CNC precision turning (single/multi-spindle for mass production), drilling, tapping (M2–M12 plastic-compatible threads), chamfering, deburring; surface finishing (polishing for POM, matte treatment for Nylon); 100% CMM dimensional inspection; fit testing with mating components (shafts, housings)
Tolerance & Precision	Dimensional tolerance ±0.02–±0.05mm; inner/outer diameter tolerance h7/H8 (ISO standard for bushing-shaft fit); concentricity ≤0.03mm; flatness ≤0.04mm; surface roughness Ra 0.8–1.6μm (ensures smooth rotation/assembly)
Surface Finish	POM: Glossy (white) or matte (black) natural finish; Nylon: Matte natural finish (optional anti-static coating); no secondary painting required (material color stable under UV exposure); deburred edges to avoid component damage during assembly
Mechanical Properties	POM: Tensile strength ≥60 MPa, operating temp -40°C to 100°C, hardness 85–95 Shore D; Nylon: Tensile strength ≥70 MPa, operating temp -30°C to 120°C, hardness 75–85 Shore D; both: Resistant to oils, greases, and mild chemicals; low noise during operation
Compatibility	Fits automotive components (sensor covers, shaft bushings), industrial machinery (gearbox bushings, bearing covers), consumer electronics (appliance covers, small motor bushings); compatible with metal shafts (steel, aluminum), plastic housings, and lubricants (silicone, mineral oil)

Application Scenarios

Automotive Systems: Nylon bushings for suspension linkages and POM covers for sensor housings—resist engine oil and temperature fluctuations, ensuring long-term reliability.
Industrial Machinery: POM machined bushings for conveyor roller shafts—low friction reduces wear on mating metal parts, minimizing maintenance frequency.
Consumer Appliances: Black POM turning covers for washing machine motor housings and white Nylon bushings for dryer drum shafts—chemical resistance withstands detergent/heat exposure.
Medical Equipment: White POM bushings for diagnostic device rotating components—non-toxic, easy to sterilize, and compatible with medical-grade lubricants.
Electronics Enclosures: Flanged POM covers for circuit board housings—dimensional stability protects internal components from dust and moisture, while low dielectric constant ensures electrical safety.
