Abstract
Providing an electrolytic integrated polishing method for metal workpieces using a special abrasive material which leaves no residual abrasive grains on surfaces of soft metals such as aluminium, and the like, and allows high-precision abrasion for optimal surface treatments such as an anodized aluminium finish at the next process. The electrolytic integrated polishing device performs rough abrasion and medium abrasion processes to the inner surface of an aluminium cylindrical workpiece by an elastic grindstone. Thereafter, the electrolytic integrated polishing device uses a sheet-form abrasive material for finishing abrasion. The sheet-form abrasive material is prepared by uniformly dispersing, short fibers including abrasive grains which is prepared by cutting an abrasion grains containing fiber into a specified length and synthetic fibers as a base material, processing them into a sheet, and hardening it with a thermosetting resin such as a polyurethane resin, an epoxy resin, and the like as an adhesive material. A plurality of these sheet-form abrasive materials are piled and are mounted on the holder through the aid of a spring plate for buckling prevention to compose the special abrasive material.
