Description of cbn wheel for gear hob grinding

Gear hob cutter is an important component in various mechanical rotation systems, so the surface finish and dimensional accuracy of gear hob cutter have high requirements. The choice of grinding wheel will also affect the service life of gear hob, and the hardness, wear resistance, high temperature stability, high temperature stability and thermal friction coefficient of grinding wheel directly affect the precision of hob grinding.

The CBN grinding wheel produced by MORESUPERHARD has the characteristics of high grinding efficiency, and effectively maintain the high precision and high life of the hob after grinding, greatly reducing the production cost, improving the processing efficiency and grinding accuracy, etc.

MORESUPERHARD ceramic CBN grinding wheel, resin CBN grinding wheel, metal CBN grinding wheel for gear hob rake surface grinding, forming grinding, and sharpening.

The single beveled CBN grinding wheel produced by MoreSuperhard can be used for hob grinding. Grinding wheel uses end grinding, the outer circle is very thin, can be ground to the bottom of the edge. CBN grinding wheels are used for forming and grinding of high-speed steel (hss) gear hob and thread cutting tools ( hardness above HRC60).
