CBN inserts

CBN ensures stable machining

CBN (cubic boron nitride) is second only to diamond in hardness. CBN is a synthetically produced material for stable machining due to high thermal conductivity.

Features of CBN

High hardness results in superior wear resistance and long tool life. High-speed cutting is applicable to heat-treated steel and cast iron. Heat conductivity is good, and prompt heat evacuation and stable cutting are possible.
