There are many cams on the camshaft of an auto engine, the rough and fine grinding of quenched cams are the key process of the cam quality. Usually, we adapt imitating shape grinding, the increasing of the workpiece speed is limited and easy to burn out. And the camber curve of cam surface is strongly affected by the diameter of grinding wheel.

When process hard cutting materials due to its different machining angle, grinding processing also enjoys more advantages!

Differences of machining hard to grind and cutting materials

Diameter of the grinding wheel is too large, the contact arc between the grinding wheel and the workpiece will increase, which will increase the grinding heat and make cooling and row cutting difficult. If the diameter of the grinding wheel is too small, it is difficult to achieve the ideal grinding speed (30m/s~50m/s), which increases the grinding thickness, increases the conformity of the grinding grains, and is easy to blunt, which increases the surface roughness of the inner hole and reduces the production efficiency when grinding the hole of workpiece.

Wheel selection is dependant on the kind of material to be ground and the type of grinding operation.

Resin Diamond Bond Wheels and Resin CBN Bond Wheels have been developed to meet the needs of precision grinding of hard materials. Natural and synthetic diamond and CBN abrasives manufactured with our high temperature bonds, guarantee high performing wheels that will grind hard materials. Wheel sizes for most CNC machines and wheels shapes for your grinding applications. If you do not find your required wheel we can manufacture to your specific needs.
