Prevents burr formation and stabilizes dimensional accuracy of finished components.

Increasing the CBN particle content and bonding strength makes it suitable for machining various sintered materials

Features

High cutting edge strength

A newly developed special binder and the particle-activated sintering method promotes binding of the CBN particles, leading to higher cutting edge strength.
MB4020 has high cutting edge strength properties for a sharper edge geometry that is ideal for preventing burrs.

Excellent welding resistance

A chemically stable, high CBN content reduces welding of the work material on the cutting edge and stabilizes dimensional accuracy of finished components.

Application range
