Home / Front & Back Turning / Solution for Machining Plastics

Precision Machining for Plastics

Smooth surface finishes and reliable chip control are achieved through Y-axis holders combined with KM1 inserts.
Performance
  • Applying Y-axis machining effectively eliminates chip control issues commonly encountered in plastic turning.
  • KM1 inserts, made from micro-grain carbide with a mirror-finish polish, ensure excellent surface quality and welding resistance.
Tooling application

Applicable to Swiss CNC lathes machining plastic materials such as PEEK and PTFE.
Supported operations include front turning (ISO), back turning, grooving, cut-off, threading, and boring.
