China M7140 M7150 Horizontal Hydraulic Mini Grinder Manual Flat CNC Heavy Duty Metal Surface Grinding Machine

M7140 M7150 Horizontal Hydraulic Mini Grinder Manual Flat CNC Heavy duty metal Surface Grinding Machine
The main performance characteristics:
This series of surface grinder is most suitable for the grinding steel, casting and non-ferrous parts of machine manufacturing industry.
The accuracy of the machine has reached the National Standard for horizontal spindle & rectangular worktable surface grinder.
The longitudinal movement of the worktable is driven by vane pump, which makes the movement smooth and low noise.
The bearings of the wheel head spindle adopt bimetal shell bearing, which can afford heavy impact and make the machine able to carry out heavy load grinding.
The cross movement of the wheel head can be driven by hand or by hydraulic oil automatically. It is easy to operate. The vertical feed of the wheel head is driven by hand. It is also assembled with rapid elevating motor, which can reduce the intention of work labor as well as enhance the work efficiency.
