Ceramic cutting tool applications with CBN difference

Cubic boron nitride ceramic materials science in the category, although attributed to, but because of CBN, SIN, Al2O3, SiN material difference in performance, cubic boron nitride ceramic cutting tool less Diamond blade and hardness. Therefore, according to its hardness and toughness of the differences in cutting ubic boron nitride less than 50HRC small depth of cut and feed small case hardened steel workpiece, ceramic tool is a better choice. Cubic boron nitride cutting tools better suited to the workpiece hardness is higher than 50HRC situation. In addition, note that the boron nitride ceramic tools and abrasive grinding mosaic roughing blade rarely used, only some grades of boron nitride inserts such as BN-S20 capable roughing and interrupted cuts.
