Crystal/Brittle Material Processing Tool UPC

Features
  1. ・The uniform negative rake angle and stable center height realize the consistent depth of cut.
  2. ・Cutting edge positional error and counter error in CNC 2-axis machining have been minimized.
  3. ・The evacuation of chips has been improved and sticking of chips reduced by the minute rake face.

Application

・Infrared aspherical lens (single crystal silicon, single crystal germanium)
・Laser lens (fluoride calcium (fluorite))
・Cemented carbide molds
