MOIST-TYPE POLISHING METHOD, ELECTROPLATING METHOD, WORKING POLISHING METHOD, WORKING POLISHING APPARATUS, BARREL POLISHING APPARATUS, WORKING SURFACE TREATMENT METHOD, AND WORKING SUPPORT UNIT FOR WORKING POLISHING APPARATUS.

摘要

The invention describes a moist-type polishing method performed such that a final polishing stage is carried out in a polishing liquid having alkalinity, and remaining polishing stages are carried out in another polishing liquid having acidity. A working polishing apparatus is constructed such that a disconnection preventive member is placed in a shaft most frontal end for a work, a polishing wheel exterior became in contact with disconnection preventive member, a fastening nut is coupled as a spiral with polishing wheel, and polishing wheel is fixedly fastened by fastening nut displacement throughout shaft. Further, a surface treatment conduction method is performed such that each surface treatment is carried out after a work is subjected to barrel polishing before or after surface treatment. Additionally, a working support apparatus includes a polishing medium-receiving container having a polishing medium received therein, and a working support arm. Moreover, a polishing medium employable for a polishing apparatus is composed by soft material grain or soft material small block.
