Abstract: A barrel polishing apparatus which can easily hold a work having a large mass and detach therefrom. The barrel polishing apparatus includes a polishing medium receiving container having a polishing medium received therein and a work supporting arm for holding the work. The position of the work supporting arm is shifted from the center of the polishing medium receiving container. The polishing medium receiving container rotates about a vertical axis to form a continuous circumferential flow of polishing medium therein and includes an upper end opening for receiving the work attached to a distal end of the work supporting arm. The work supporting arm is oriented diagonally toward a direction of the continuous circumferential flow of polishing medium.
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.
