Haris Division supplies 2 types of CBN micron powder - of black and amber color. CBN HM1 is a derivative product from CBN H200 mesh size. Angular shapes of grains promote high abrasive properties of powder, which is good for high specific removal rates. Variant CBN HM1 60N with Ni 60% coating is offered for resin bond.
CBN HM2 is a derivative from CBN H500 with the amber color. Grain shape of this micron-size powder is more regular, than that of CBN HM1. High degree of chemical homogeneity and minimal inclusion of CBN H500 dashes, as a basic material, endow CBN HM2 with hardness and thermal stability. These properties make CBN HM2 popular in using it for sintering plates of PCBN for blade tools.
CBN HM1 and HM2 are used for finish grinding and super-finishing applications, as well as for fine-grinding, finishing and polishing of hardened steels, super-alloys and other metal materials and abrasive pastes and emulsions also.
The comparative spectrographic analysis of chemistry content of two types of CBN Micron powder samples. The spectral foldover of CBN HM1 black and CBN HM2 amber is made at a roentgen fluorescent spectrometer BAIRD EX-6500.
