CGM Installation instructions

  • Loose the old adjustment head.
  • Setup M106 adjustment head and fasten tightly.
    If it doesn't fit, please process the holes according to M106 graph.
  • Set up the chuck and fasten tightly.
    (The insulation pad should be in between of M106 and the chuck)
  • Use EDM negative line to make sure the chuck and machine wouldn't have short circuit.
  • Use ST-164 and ST-165 to adjust X and Y axis's flatness and parallelism.
