Superfinishing Process of Ball Bearings

Abstract

Superfinishing is one of the most crucial machining process stage in the production of ball bearings. This process determines the quality, form, and geometry of ball bearing raceway. The factors influencing the performance of the superfinishing process are not only processing parameters but also the characteristics of the superfinishing stone used. In this study, experiments with different material components and chemical compositions of stones were conducted to achieve the desired surface topography, specifically on the inner raceway of a 6206-type bearing. In experiments using four different superfinishing stones, Ra and Rz measurements were taken to evaluate the performance of the stones. As a result of the experiments, it was observed that the White Alumina stone provided the best Ra results in these process parameters.
