SPG-15 SERIES

Description

All major parts are casting (FC300, heat treated)
Machine base is a one-piece casting.
Several brackets inside the base contribute to the 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.
