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

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 with 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

New full face CBN

Full face and solid CBN can be used for higher depths of cut and chamfering when conventional brazed tip CBN inserts are not suitable.

Refer to the cutting conditions on page 9 for the maximum recommended depth of cut.

A wide range of honing types

MB4020 with wide range of hones including the SF and SE. The SF hone is able to control burrs with the increased insert hone sharpness. The sharpness of the SF hone reduces cutting forces with reduced cutting resistance and helps control burrs that otherwise may occur. The SF hone is the first recommendation for precision surface finish requirements. If insert chipping occurs then use SE, FS and TS hones recommended for the balance of hone edge strength and the reduction of insert chipping.
