As the table moves back and forth, the entire table moves so that over time, the grinding wheel passes over the entire surface area of the table. This process, while slow, is precise. With each pass, as much as 0.001 of material is removed. The maximum thickness to be removed using this process is 0.008. Otherwise, milling should be used.

High-speed grinding works well in hardened tool steels, the harder the material the better. Unless however, the wheel speed is very high – in the range of 35,000 to 40,000 sfm or higher. Only then does high-speed grinding work well in softer or gummy materials like stainless steel and aerospace alloys and only plated cBN would then be used.

When internal grinding, the diameter of the internal grinding wheel is small, and the rotation speed of the grinding wheel is limited by the rotation speed of the internal grinding tools. Therefore, the grinding speed is usually within 20-30m/s. Due to the low grinding speed, the surface roughness of the workpiece is not easily reduced. b.

Dry grinding, as in a jet mill, uses a single pass process; material enters the mill, passes through, and is expelled, reduced in size. In contrast, wet grinding uses a process of recirculation. The slurry is exposed to the grinding media over and over, for hours if necessary, until the desired particle size is achieved.
