CBN inserts when machining hardened bearing steel Precautions

A) dry cutting, with the knife and other reasons as a result of the need to add water, can be used Valin BN-H10 grade, when its wet cutting tool life better get better. (2) CBN grade selection tool: the car synthetic diamond of polycrystalline diamond steel, the selection of Valin superhard BN-H20 grade CBN inserts, Arbor outstretched as short as possible to reduce vibration, to obtain better surface roughness . (3) If it is hardened bearing steel large allowance, recommended BN-S20 grades CBN inserts.
