MM2 – 5-axis CNC automatic polishing machine for shank tools

  • Polishing processes for shank tools such as drill bits, milling cutters, countersinks, etc.
  • Removal of droplets after coating, and polishing to improve chip flow
  • Deburring of HSS shank tools or HSS countersinking tools
  • Targeted edge preparation and rounding of shank tools before coating
  • Increase in punching time through defined cutting edges
  • Continuous operation or batch mode possible
  • Automatic measurement of the tool length and diameter via optical sensors
  • Recipes which can be scaled based on diameter and length for various tool geometries and polishing discs.
  • Windows-based Beckhoff PC controller incl. remote maintenance option
  • 15-inch touchscreen
  • Electrical connection 16 A / 380-480 V
  • Simple, menu-guided operation incl. monitoring of all parameters for a reproducible process incl. runtime monitoring of the polishing discs
