Improvements in Surface Integrity and Fatigue Strength by the CBN Wheel Processing

Abstract

The CBN wheel has been noted for its advantageous properties of long life expectancy and exceptional grinding efficiency and accuracy. In this paper, the authors look at the CBN wheel from the viewpoint of the quality of workpieces processed by the CBN wheel to compare the work surface integrity and fatigue strength obtained by the CBN wheel with those by a conventional SA wheel. The CBN wheel can improve the quality and strength of work materials. This suggests the significant possibilities of the CBN wheel for reducing the size and improving the efficiency of products, if it replaces the conventional wheels; namely, the processing by the CBN wheel even has an impact on product design.
