Operation principle of Hydraulic Cylinder Finishing Tools

roller burnishing tools - Extrusion burnishing schematic diagram

Roller burnishing pressing is a commonly used surface strengthening method for metal materials. It exerts a certain amount of pressure on the workpiece surface by rolling the head. The roller head is rolled in the hole wall of the hydraulic cylinder, the workpiece is rotated, and the rolling head is given in the direction of the workpiece axis. When the compressive stress on the surface of the inner hole exceeds the elastic limit, dislocation, slippage and breakage occur between the...
