Engine is the heart of any vehicle and the valve seat in the cylinder head is a critical operation which decides the power output or performance of the engine. Today wide segments of the industry are using CBN tools to machine the valve seat ring.

Valve seat material made up of hard particles as well micro structure matrix which has poor machinability. All engines whether diesel or petrol has this application where CBN can enhance tool life and surface finish quality. Sumitomo having wide range of Grades to cover different hardness and composition of valve seat material do contact us for more details.
