CBN inserts when machining hardened bearing steel cutting parameters

Finish turning with CBN blade hardened bearing steel, its cutting speed is generally 80 ~ 120m/min, the higher the hardness of the workpiece, the cutting speed should take a low value, such as car 70HRC synthetic diamond of the workpiece, the cuttingDiamond bladeshould choose 60 ~ 80m / min. choice for depth of cut, if the machine rigidity, Valin superhard HLCBN tool in BN-S20 depth of cut material can be completed one pass after quenching most margin; leaving only about 0.3mm as the finishing allowance ; feed asked to choose according to the roughness, the processing suitable 0.1mm / r about feeding.
