Grinding Properties of Monocrystalline and Microcrystalline BORAZON CBN Grinding Wheels

Abstract

This paper is an attempt to clarify the grinding properties of monocrystalline and microcrystalline CBN grinding wheels. The grinding performance of the microcrystalline CBN wheel is 2 to 3 times better than that of monocrystalline. In high efficiency grinding, its initial grinding force doesn't go beyond a certain level as does the monocrystalline. Its grinding force is independent of the influence of increasing stock removal, if used under optimum grinding conditions. Furthermore, it has a long service life and is free from burning even in high efficiency grinding. These and other findings indicate that the microcrystalline CBN wheel has properties that are ideal for high efficiency, accurate grinding.
