With the development of the cutting technology, the cutting tools manufacturers researched new tool materials “cubic boron nitride” which can be use for turning instead of grinding, it will have Compressive stress when with traditional CBN inserts roughing the ball screw raceway, it will be easily make the insert chipping. Finally Halnn research non-metal adhesive solid CBN inserts BN-S20, solving the problems of chipping.
