The spherical ball surface roughness of the spherical compensator produced by our factory requires R_σ0.8, due to the large spherical diameter (maximum Sφ750mm). Existing processing equipment is difficult to meet the drawing requirements. To this end, we have made a simple spherical grinding machine, which is introduced as follows: Second, the structural principle The structure of the spherical grinding machine is shown in Figure 1. It consists of a power chuck 1, a grinding head ring 2, a grinding head ball seat 4, a ball shaft 5 and a bracket 6. Power department
