The high carrying capacity of the hard-toothed hydraulic shearer gear. It is after fine cutting, and then surface quenching or carburizing quenching to improve hardness. However, in heat treatment, the hydraulic shear machine gear will inevitably cause deformation. Therefore, after heat treatment, the manufacturer must grind, grind or finecut. In order to eliminate the error caused by deformation, improve the accuracy of the cutting machine gear.
