A method and apparatus for randomly lapping a ball bearing race and removing the deviations from a smooth cross race curvature wherein the bearing race is rotated about its nominal center, a conforming ball in a slurry of fine abrasives is rotated in a highly random manner in the race thus transferring the uniform radius and finish of the ball to the bearing race surface.

Precision Lapping of Ball Valve Manufacturers Diamond compounds, powders, slurries and lubricants for the precision lapping of precision balls and seats. Whether it is a gate, ball or butterfly valve, the extreme pressures and corrosive elements that valves are exposed to can create leaks in the system; this can lead to costly onsite repairs.

Lapping is an averaging process where the greatest material removal occurs where the high points of the surface of the part contact the flat lap plate. The object is to produce parts with a uniformly smooth and usually flat surface. A surface that has been lapped exhibits a dull, non-reflective and multi-directional appearance.

Lapping is used as the last process to improve the precision and surface quality of a ball screw. However, the existing ball screw lapping method is very complex, time-consuming, and has low production efficiency. Only a few studies studied the process mechanism of ball screw lapping. In addition, the precision retaining ability of a ball screw affects its service life and performance …

You might try a CBN charged ball lap. Running it driven with an eccentric pin to drive it will improve wear rate and form retention. Alternatively try using the silicon nitride ball for tooling pressing it into the cone to form the seat. The silicon nitride is incredibly strong in compression, exceeding 400,000 psi compressive stress.
