Solid CBN

Description

SFD CBN, with characteristic of high hardness, high wear resistance and high thermal stability, is made of selected CBN powder and sintered at high pressure and high temperature, with metals or ceramic binders. BN series is solid CBN.

Application

SFD CBN is ideal for tools in machining of high hardness and hard processed ferrous materials (HRC45-65), such as hardened steel, gray cast iron, heat resistant alloy, high-speed steel, hard facing alloys, Ni-Cr alloy, powder metallurgy metals. CBN is typically used to machine brake discs, engine blocks, engine cylinder liners, brake drums, flywheels, valve seats and guides, gears, mold and die parts, etc.

Application Area

SF-Diamond CBN (polycrystalline cubic boron nitride) is ideal for tools used to machine hard ferrous metal items (HRC45-65) such as high speed steel, bearing steel, cast iron,etc.

It’s typically used to machine brake discs, engine blocks, engine cylinder liners, brake drums, flywheels, valve seats and guides, gears, mold and die parts etc.The surface finish of the workpiece is good, which can replace grinding with turning, greatly improve labor efficiency and effectively reduce production costs.
