摘要

The wet buffing process is carried out such that the final buffing step is carried out in an alkaline buffing liquid and the remaining buffing step is carried out in another acidic buffing liquid. The workpiece buffing device is characterized in that the workpiece buffing device is arranged such that the connection disassembly member is disposed at the front end of the shaft relative to the workpiece, the outer side of the buffing wheel contacts the disconnection preventing member and the tightening nut engages spontaneously with the buffing wheel, Thereby firmly securing it to the shaft. Further, the surface treatment execution method is performed so that the workpiece is subjected to barrel buffing treatment before or after the surface treatment, and then each surface treatment is performed. Further, the workpiece supporting apparatus has a buffer medium receiving container and a workpiece supporting arm accommodating the buffing medium. Furthermore, the buffing medium usable in the buffing device is composed of a small block of a soft material or a grain of soft material.
