1.This universal cylindrical grinding machine is a mojor grinding machine professional advantages of manufacturing units in the M1320, M1420 type on the basis of draw to impove heavy duty grinding machine, with high cutting precision, high rigidity and high efficiency. Suitable for grinding cylindrical and conical workpiece.
2.The workpiece, cylindrical grinding wheel, inner circle grinding wheel, oil pump and cooling pump are driven by independent motor.
3. Worktable longitudinal movement by hydraulic continuously variable transmission can also be handwheel drive.
4.Grinding wheel frame transverse feeding fine turning can be made by the hydraulic feed and fast automatic cycle.
5. Grinding wheel rack main shaft diameters, motor power increase, grinding wheel rack oil pool temperature rise is small, high grinding rate.
