Description
Technical Field
[0001] The utility model relates to the technical field of roller burnishing cutters, in particular to an ultra-precision elastic inner hole mirror roller burnishing cutter. Background Art
[0002] In the field of hole processing technology for hardware workpieces, the roller burnishing process is a chipless pressure finishing technology. It uses the plastic deformation characteristics of metal at room temperature to apply a certain pressure to the surface of the workpiece to be processed through the roller burnishing cutter, so that the metal surface produces plastic deformation, and the wave peaks on the microscopic surface of the workpiece are squeezed to the original residual concave troughs, reducing the surface roughness of the workpiece. The surface metal of the workpiece is plastically deformed by the roller burnishing cutter, so that the surface organization is cold hardened and the grains are refined, forming a dense fiber shape, and a residual stress layer is formed, which improves the hardness and strength, thereby improving the wear resistance, corrosion resistance and compatibility of the workpiece surface, and achieving the purpose of improving the surface quality of the workpiece. It can complete finishing and strengthening at the same time, and has advantages that cannot be achieved by grinding and turning processes, and can obtain a metal surface that is nearly as smooth as a mirror.
[0003] However, when the existing roller burnishing cutter is processing the hole of the hardware workpiece, it will have a rigid collision with the hole wall. The diamond roller burnishing cutter head will have a rigid contact with the microscopic size changes of the part, which will cause the diamond to crack and break, and reduce the service life of the cutter head.
