Abstract

A wet type buffing method is practiced such that a final buffing step is conducted in a buffing liquid having alkality and the remaining buffing steps are conducted in other buffing liquid having acidity. A work buffing apparatus is constructed such that a disconnection preventive member is disposed at the foremost end of a shaft for a work, the outside of a buffing wheel comes in contact with the disconnection preventive member, a tightening nut is threadably engaged with the buffing wheel, and the buffing wheel is tightly fixed to the shaft by displacing the tightening nut along the shaft. In addition, a surface treatment conducting method is practiced such that each surface treatment is conducted after a work is subjected to barrel buffing before or after the surface treatment. Additionally, a work supporting apparatus includes a buffing medium receiving container having a buffing medium received therein and a work supporting arm. Further, a buffing medium employable for a buffing apparatus is composed of grain of soft material or small block of the soft material.
