Hermes CBN crankshaft grinding wheels stand out where it really matters.

Product description

When used for grinding the pins and journals on crankshafts, Hermes crankshaft grinding wheels with segmented CBN coatings are characterized primarily by very high profile stability, something which is particularly apparent at the critical points on radii.

Hermes new high-performance V42 bond allowed the grinding properties of the CBN coating to be improved significantly.

Hermes superabrasives for external cylindrical plunge grinding can be used at operating speeds of up to 160 m/s. Despite high stock removal rates, excessive thermal load on the workpiece is avoided.

Compared to conventional grinding wheels, this results in significantly extended lifes for abrasives, in turn leading to reduced tooling-up times and tool costs. The consequence for our customers is a more economical grinding process. Hermes supplies these high-tech grinding wheels with an external diameter of up to 750 mm.
