Halnn CNGN Cbn Cutter Inserts For Hard Turning 40CrMo Hardened Steel Ball Screw

1. Halnn Tools CNGN CBN Cutting Inserts for Hard Turning 40CrMo Hardened Steel Ball Screw

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.

Advantages of Halnn solid cbn inserts BN-S20 hard turning ball screws;

(1) High hardness, abrasive resistance and heat resistance

(2) Strong impact resistance, avoid the insert chipping, damage problem

(3) High speed cutting, improve the efficiency

(4) Dry cutting method reduce the pollution

(5) Long tool life, will be 1.5~2 times of traditional cbn inserts.
