Halnn BN-S300 Solid CBN Inserts machining Gray Cast iron

Gray cast iron are mainly used for CNC Lathe and automotive industry, most of them are bulk production, we commonly processing gray cast iron using traditional inserts, however, traditional cutting tools can meet our process requirements, CBN inserts are mainly used for processing high hardness iron and hardened steel industry, and common cast iron also use cbn inserts.

The advantages of machining gray cast iron with BN-S300 soid cbn inserts

(1)   Belong to the nonmetal adhesive cubic boron nitride blade,

(2)   Own high linear speed compared with coating carbide inserts,

(3)   Have good roughness. 

Application industry

BN-S300, Automobile part, pump parts, motor cover, motor housing, etc industry, such as brake disc/drums, pulleys and other components. Cast iron engine blocks, cast gearbox housing, cylinder liner, iron-based sintered metal.

Suited Materials

BN-S300 mainly used for machining cast iron parts and iron series sintered alloy.
