SPG-15 Series

Double Column Surface Grinder

Specification:

  • All major parts are casting (FC300, heat treated)
  • Machine base is a one-piece casting.
  • Several brackets inside the base contributing to great rigidity.
  • Machine leveling can be as easy as turning a bolt on the adjustable pad.
  • Bellows to protect the guide ways.
  • High Precision couplings on the wheelhead prevent slip and vibration.
  • X- axis: Hydrodynamic lubrication on the double V guide ways assuring non-wear out.
  • Y & Z axis : Box guide ways with forced lubrication ensuring precision, rigidity, and less frication.
  • Independent electrical cabinet with heat exchanger and light.
  • Coolant system is equipped with paper filter and magnetic separator.
  • Auto oil feeder on ballscrews provides timed lubrication.
  • Machine base is a one-piece casting, Leaking is out of the question.
  • The CNC control has both RS232 and CF port, DATA could be saved outside of the machine.
  • Various CNC grinding programs packed in.
