roller burnishing tool technology, Roller Burnishing Tool structure

Roller Burnishing Tool is a processing tool with cold extrusion and plastic. Its purpose is to reduce the surface roughness of the metal workpiece, improve the surface finish while increasing the hardness and fatigue resistance of the product, and enhancing the product's resistance to pressure wear and corrosion, and then increasing service life, the result is so much reduced industrial processing and production costs. Due to the popularization of the automobile industry, the hydraulic cylinder industry continues to develop. The...
