Spherical Grinding Quality

Factors affecting quality of Spherical Roller Bearings ...

Spherical Rod End Bearings: A type of spherical bearing that consists of an eye-shaped head with integral shank forming a housing and a standard spherical plain bearing, or a spherical plain bearing inner ring. As the name implies, they are used at the end of rods and have either a male or thread for mounting.

An Introduction to the Optics Manufacturing Process

Loose abrasive grinding uses inverse spheres of the same radii ground together so that the hills and valleys on the optics will wear away to produce a true sphere. Slurry flows in between the blocked parts and the spherical tool to keep the parts cool and wash away debris created during the grinding process. Polishing
