Grinding Machine
Centerless grinding machines can be sued for fine grinding of end face, excircle and conical surface of batch of shafts. It is usually used for shaft machining which has high requirements on precision. The internal and external cylindrical grinding machine is especially good at machining of highly precise parts, especially parts of materials which are heat treated and of which the hardness is special. For example, hardness of tungsten steel and alloy steel should be higher than HRC60.
The outer diameters of applicable machining targets are from 0.3 to 60. And the length is from 3MM to 2000MM. The best precision can be up to 0.0005MM.

Advantages and features
The grinding machine carries out workpiece to meet parts tough surface requirements. Depending on various machine type and by precise fixtures alignment it achieves required surface flatness requirements. Our machine uses a pump in screw system that gives relatively high rotation precision and vibration resistant performance and noise free and stable grinding operation.
Surface grinders which can be used for grinding of complex square and round workpieces. The grinding precision can be up to 0.002mm. Besides, we are equipped with single side grinder and calender which can be used for improving flatness and reducing roughness of the surface of the workpiece. The roughness of both flat and round workpiece can be up to RA0.02um, RZ0.1um. And the flatness can be up to 0.001um.
