Grindmaster 3-Axes Complex CNC Internal/External Grinder

  • Heavily ribbed box-type base made in Meehanite casting with roller type linear slideways for the X-Y-Z-axes.
  • Modular design to perform complex and precision grinding operations.
  • FANUC Control and servomotors in all axes. Workhead (X-axis),Wheel head (Z-axis) and internal/external (Y-axis).
  • Grinding Operation in one chuck clamping:
    - Internal diameter straight grinding operation / Outside diameter straight grinding operation
    - Internal diameter taper grinding operation / Outside diameter straight grinding operation
    - Internal diameter straight grinding operation / Outside diameter taper grinding operation
  • Autosizing devices can be equipped to reinforce the accuracy performance of the grinding operations.
  • Internal grinding spindles: 10500/16500/29000 rpm
