Solid CBN inserts

Solid cbn inserts are used for rough and finish machining of hard steel ,cast iron and hard surface workpiece.

Cubic boron nitride inserts (CBN Inserts) is a high-performance type of cutting tool material from a polycrystalline mass.

CBN is a high hardness, high heat resistance crystal synthesized by boron and nitrogen under high temperature and high pressure.

Specification

 

Applications of solid CBN inserts

Processing workpiece: rough and finish machining of the hard steel ,cast iron and hard surface workpiece.

Processing materials: ferrous materials possessing hardness from approximately 45 HRC as well as gray cast iron, Cr-chilled cast iron and wear alloys on a cobalt, nickel or iron basis.
