One of the areas where super-hard (CBN, Diamond) grinding wheels are superior to those made with Al2O3 or SiC series of raw materials is the CBN/Diamond grinding wheel for internal grinding.
In the inner circle grinding process, the requirements for improved performance of the processed product, miniaturization of components, and excellent grinding processing are gradually improved. The ceramic CBN grinding wheel improves the surface roughness, roundness or cylindricity shape, and reduces the replacement of the grinding wheel. Frequency and increased trim interval time, etc., increase production efficiency and reduce processing costs.
The maximum outer diameter of the grinding wheel is limited to the inner diameter of the workpiece to be grounded, so the outer diameter of the inner grinding wheel will be small.
The grinding speed of the inner grinding wheel is generally 20,000 ∼ 50,000 rpm, which rarely exceeds 100,000 rpm, and the mechanical strength should sufficiently prevent the flange from loosening or the degree of vibration of the machine itself.
