Thermal Stability CBN Turning Insert Tool High Hardness wear resistance
High Quality CBN Turning Inserts
CBN is a synthetically produced material for stable machining due to high thermal conductivity. PCD is ideal for non-ferrous metals, non-metal turning, milling and other types of cutting.
PCBN-tipped with very high hardness and high heat stability under about 1300°C of the cutting temperature. It's mainly suitable for machining hardened steels of HRC50~60(e.g. carbon tool steels,ball bearing steels,die tool steels and high speed steels etc),gray cast irons, cold hard cast irons and Ni-,Co-,Cr-, or Fe-based high temperature alloys.

(CBN) is a superhard material second only to diamond in hardness. It not only has many excellent properties of diamond, but also has higher thermal stability and chemical inertness to iron group metals and their alloys. As an engineering material, it has been widely used in the processing industry of ferrous metals and their alloys. At the same time, it has been applied in a series of high-tech fields due to its excellent thermal, electrical, optical and acoustic properties, and has become a promising functional material.
