Abstract
CBN wheel grinding has been noted for its advantageous properties of long life expectancy and expectalbe grinding efficiency and accuracy. In this paper, the authors look at CBN wheel grinding from the viewpoint of the quality of work pieces processed by CBN wheel grinding with those by a conventional SA wheel grinding. CBN wheel grinding can improve the quality and strength of materials. This suggests the significant possibilities of the CBN for reducing the size and processing with the CBN wheel even has an impact on product design.
