Application:
Worldia chip breaker PCBN inserts are used for machining hardened steels, cast irons and sintered irons as well as powder metallurgy components.

Description of PCBN Material:
Cubic boron nitride is the second hardest material in the world invented successfully in 1957. The hardness of CBN’s single crystal is HV8000-9000 while the hardness of PCBN is HV2500-5000, so its abrasive resistance is considerably better than tungsten carbide and ceramics. With high temperature oxidation resistance at 1000℃, CBN will do not have any chemical reaction together with ferrous material at 1200-1300℃. So CBN material is ideal for cutting ferrous materials, the CBN cutting tools are used for cutting hardened steel, cast iron, sintered iron as well as powder metallurgy components.

Features of Chip Breaker PCBN Insert:
1. Special 3D slot shape reduce the cutting force, and obtain the higher accuracy of dimensions and positioning.
2. Same slot shape of PCBN insert can be fine processed and rough processed by chip breaking.
3. Suitable for machining hardened steel/
4. This cutting tool is applied to remove carburized layer, the quenching part and non quenching part both can be cut.

Worldia Chip Breaker PCBN Insert:
1. Premium CBN materials, mini tip, less cost and better performance
2. Clear mark of PCBN material makes it easily to recognize
3. Clear numbers of tips make the insert easily to management
4. Special welding technology, firmly welded
5. Chip breaker inserts can solve the problem of long chips while the process
6. Clear serial number on carbide substrate makes it easily to track the PCBN insert quality and the feedback information
