For high performance femoral balls in hip implants, roundness, size and surface finish consistency are key quality criteria

The first step is to precisely grind the initial part to size

This is followed by a series of fine grinding steps that progressively improve the surface finish of the spheres

Tyrolit grinding wheel is a special grinding wheel for femoral ball production, but there is a problem of serious wear during the production process

The last step is the polishing operation, to make a mirror-level finish on the surface of the ball
