ロードセルを内蔵した工具を用いたSUS420材のボールバニシング加工

抄録

Burnishing process is a finishing process caused plastic deformation by pressing the high hardness ball to metal material. This process can improve the surface roughness. In addition it can give the work hardened layer and compressive residual stress layer on the surface of materials. In this research, a load-cell built-in burnishing tool is used to process the SUS420J2 steel. A variety of processing conditions is tested, and the surface roughness, hardness and residual stress of the processed material were examined.
