Applications of Grinding Technology. Low surface roughness: Grinding with surface grinder belongs to micro-feed grinding, and the cutting depth is small, which is beneficial to reduce the surface roughness value of the workpiece. The surface grinding machine processed surface roughness can reach Ra0.01μm. High dimensional accuracy:
