PTFE Turning Process

The process involves precision lathe machining of polytetrafluoroethylene (PTFE) through optimized tools, cutting parameters, and dry cooling. This achieves high precision (±0.02 mm) and low surface roughness (Ra 0.8-1.6 μm) while preventing material deformation and tool adhesion.  

Advantages

  • Extreme environment resistance 
  • Functional integration
  • Cleanliness and safety 
  •  Cost efficiency

 

Typical Products  

  • O-rings, valve seats (pressure resistance 20 MPa)  
  • Bearing bushings (friction coefficient <0.1)  
  • Endoscope catheters (antibacterial surface treatment)  
  • Wafer carrier rings (electrostatic dissipative-grade PTFE)
