Plastic CNC Machining
Plastic CNC machining covers high‑performance engineering plastics such as POM, PEEK, nylon, PVC and acrylic. These materials feature lightweight, insulation, wear‑resistance, low friction and chemical resistance, widely used for custom non‑metal precision parts across multiple industries.
Machining Precision
Stable tolerance ranges from ±0.05mm to ±0.10mm for standard plastic parts; high‑precision engineering plastics like PEEK can reach ±0.02mm ~ ±0.03mm with strict process control.
Processing Difficulties && Our Solutions
Difficulty 1: Thermal Deformation && Melting — Plastics are sensitive to cutting heat and easy to melt, deform or produce burrs during high‑speed machining.
Solution: Adopt low‑speed, sharp‑tool cutting, use air cooling instead of liquid coolant, and optimize feed rate to reduce heat buildup.
Difficulty 2: Low Rigidity && Chipping — Soft plastics are prone to chipping, cracking or dimensional instability under clamping force.
Solution: Use soft clamping fixtures, apply low‑pressure clamping, and adopt layered machining to avoid stress damage.
Application
Commonly used in automation equipment, medical devices, electronic insulators, food‑grade components, robot accessories and precision mechanical parts.

PTFE CNC Machining
PTFE (Polytetrafluoroethylene, Teflon) is a high‑performance fluoropolymer with excellent self‑lubrication, low friction coefficient, high‑temperature resistance, chemical inertness and insulation properties. It is widely used for non‑stick, corrosion‑resistant and insulating precision components.
Machining Precision
Stable tolerance ranges from ±0.05mm to ±0.10mm for standard parts; high‑precision PTFE components can reach ±0.02mm ~ ±0.03mm with strictly controlled processes.
Processing Difficulties & Our Solutions
Difficulty 1: Soft Texture & Deformation — PTFE is extremely soft and elastic, easy to deform under clamping force or cutting pressure during machining.
Solution: Adopt low‑pressure clamping, layered cutting and sharp‑edged tools to reduce extrusion deformation and ensure dimensional stability.
Difficulty 2: Burr Generation & Poor Surface Finish — PTFE tends to produce long burrs and rough edges after cutting, affecting assembly and sealing performance.
Solution: Use high‑speed finishing cut and optimized tool paths to minimize burrs, and perform post‑processing deburring for clean edges.
Application
Mainly applied in medical equipment, chemical industry, food machinery, semiconductor, automation and aerospace, for seals, gaskets, insulators, sliding parts and anti‑corrosion components.

PPS
PPS CNC Machining
PPS (Polyphenylene Sulfide) is a high‑performance engineering plastic with high temperature resistance, excellent dimensional stability, corrosion resistance, flame retardancy and good mechanical strength. It is widely used for precision structural parts under harsh working conditions.
Machining Precision

Processing Difficulties && Our Solutions
Difficulty 1: Brittle Property && Chipping — PPS has high hardness but poor toughness, easy to crack or chip during sharp‑angle cutting.
Solution: Use sharp carbide tools, adopt low‑impact cutting parameters, and avoid sudden feed changes to prevent edge chipping.
Difficulty 2: Thermal Stress Deformation — High‑speed cutting heat may cause slight deformation, affecting long‑term dimensional accuracy.

Processing Difficulties & Our Solutions
Difficulty 1: Chip Splitting & Burrs — POM is hard and brittle, easy to produce sharp burrs and fragmented chips during high‑speed cutting.
Solution: Use sharp high‑speed steel or carbide tools, adopt high‑speed finishing cuts, and conduct precise deburring to keep edges clean.
Difficulty 2: Thermal Deformation — Cutting heat easily causes local melting and dimensional instability, especially for thin‑wall parts.

Surface treatment
Plastic Surface Finishing
Plastic surface finishing covers a series of post‑processing treatments applied to CNC‑machined plastic parts such as POM, PTFE, PPS, nylon and acrylic. It improves surface smoothness, removes burrs, enhances wear resistance, chemical stability and visual appearance to meet assembly and industrial application requirements.
Common Finishing Processes
We provide deburring, manual polishing, sanding, tumbling, flame treatment and surface smoothing. Each process is customized according to plastic material properties and usage scenarios.
Processing Difficulties & Our Solutions
Difficulty 1: Material Softness & Surface Damage — Most plastics are soft or elastic, easy to scratch, dent or deform during polishing and deburring.
Solution: Use fine‑grade abrasives, low‑pressure manual finishing and targeted deburring tools to avoid over‑processing and surface damage.
Difficulty 2: Heat‑sensitive Deformation — Excessive friction heat during finishing may cause melting or warping of thermoplastics.
Solution: Adopt low‑speed cold finishing methods, control processing time and pressure strictly to maintain dimensional stability.
