Diameter (mm): Customizable
Thickness (mm) : Customizable
Aperture (mm): Customizable
Material: CBN

Product introduction
Auto Engine Valve electroplated CBN grinding tools are used for the forming grinding of the engine lock slot,neck,tapered surface,and the end surface of the engine valve,as well as the cutting off and multiparts processing, including valve groove wheel, Valve Tip End Grinding wheel, Chamfering wheel for Round Shaft and Tube, Valve Head & Seat Grinding tool, Valve Cut Off wheel.

Suitable for processing 40Cr、4Cr9Si2、4Cr10Si2Mo、21-4N、23-8N and other ordinary alloy steel and heat-resistant alloy steel.

The maximum working linear velocity can reach 180m / s, belong to creep slow form grinding. Grinding wheel and workpiece have large contact area and high speed ratio, can achieve high material removal rate, improve the machining efficiency and reduce machining cost enormously, and needn't trim.
The contour accuracy of the work piece can reach 0.01mm, the base of the grinding wheel can be recycled.
