In some cases, there are obstructions built into the parts to be tested that would prevent a completely spherical ball from reaching the surface to be evaluated.
Grinding a cylindrical stripe of reduced diameter on the outside diameter of the ball will provide the required clearance that will allow access to the spherical surfaces of interest.
