MB4020

High cutting edge strength

Newly developed special binder provides high cutting edge strength. Burrs and plasticity characteristics must be suppressed in interrupted cutting of sintered alloy machining. Extremely superior work accuracy is realized because MB4020 allows selection of a sharper cutting shape to perform its high cutting edge strength.

Eexcellent welding resistance

There is almost not welding to the tool cutting edge because the stable CBN contents is high.
Work cutting dimensional accuracy is stable.

New Edge Treatment

Expansion SF and SE to edge treatment system of MB4020. SF and SE suppresses burr of work piece and achieves good surface roughness, because SF and SE are sharper than conventional edge preparation and low cutting resistance. Recommend SE, when chipping cutting edge occur using SF.

Full face CBN insert can be used for chamfering that use　higher depth of cut
