Surface Grinder

Surface Grinder

  • The machine has reasonable structure, adapting cross saddle structure, good rigidity, beautiful appearance, convenient operation.
  • Provide semi-closed cover and enclosed cover according to customer’s requirements.
  • Transverse movement (front and rear) of worktable is driven by servo motor and transmitted by precision ball screw, which can ensure accurate position, automatic feed according to the program and fast forward and rewind functions.
