Adopt the tehnology that the tooth material and the backing materail welded by electron beam welding.Then complete the processing of grinding teeth,setting teeth and heat treated the teeh.The hardness of the teeth is high up to HRC68-69.The wear resistance,the sharpness ,cutting and backing materials performance and the fatigue resistance are all perfect .What is more the alveolus is smooth.
The world's first application technology of separate heat-treatment in tooth materail and backing material.
M51 tooth material were quenched by Germany top vacuum furnace under 196 degree copious cooling.
The teeh are in more general use after sepcial cooling,which fit for cutting different alloy steel and die steel.
The high chromium alloy spring steel as backing material increased the crosswise tolerance and the anti-fatique tolerance.
