Abstract
To improve the quality of cylindrical roller bearing, e.g. seizure-proofing, one of the most important factors is edge quality of the end of a roller. It is required that rolling surface and end surface connect with chamfer with a large radius of curvature. To form such a profile, we proposed a machining method by means of water jet technology. First, a profile is formed in rough machining process with one of machining characteristics of water jet, that is, distribution of machining capability within a cross section of a water jet. Next, required surface roughness is realized with using smaller particles with polishing mechanism.
