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.
The machine moves smoothly and has reliable performance, low noise and stable accuracy.
It is easy to operate and deeply welcomed by the customers.
