Solution for Machining PlasticsFor turning small parts ｜ Y-axis holder + KM1 Insert

New Chip Control Proposal for Plastics

The Realization of Stable Machining

Improved chip control with a Y-axis holder
High quality surface finish with KM1

Performance

  • Applying Y-axis machining eliminates chip control issues
  • Mirror-finish polished fine grain cemented carbide ensures an excellent surface finish

Tooling application

Automatic lathe (Gang type) machining plastic materials (PEEK/PTFE, etc.)

Features of TFD type

* The insert geometry of the TFD-style is the same as a DCGT style.
* The TFD style insert is designed with a 0.012 inchwiper flat when the insert is set in the holder; enabling improved work surface finish at increased feed rates.
* The TFD-style inserts can be used on toolholders (SDJC-N, SDJC-N-F, SDJC, CH-SDUC, Y-SDJC, Y-SDJC-OH) with a cutting edge angle of 93°.
