Method for producing a cylindrical buff

摘要

Method for producing a cylindrical buff (7) with an abrasive surface (7a) is disclosed. A plurality of circular buff material is stacked to form a cylindrical shape. The buff is soaked into a liquid and the liquid is frozen to harden a abrasive surface of the buff. The buff is rotated and the abrasive surface is cut by a cutting tool (15) to smoothen the abrasive surface. Another method for producing a cylindrical buff with an abrasive surface is also disclosed. A plurality of circular buff material is stacked to form a cylindrical shape. The buff is rotated and a liquid is jetted with high speed toward the abrasive surface of said buff to smoothen the abrasive surface.
