CNC Hydraulic Surface Grinding Machine

Robust construction and heavy duty design.
The longitudinal movement of the working table is drivn by hydraulic power.Stepless speed regulating.
The longitudinal movement of grinding head is driven by hydraulic power.Stepless speed regulating.
The grinding head is equipped with fast speed lifting motor,which increase the efficiency.
The vertical and horizontal rail way for grinding head is pasted with PTFE soft belt.Good wear resistance.
High precision,good stability and low noise.
GSK,Siemens,Fanuc CNC system is for option.
