ROUGHENED SURFACE FORMING WORKING METHOD OF SURFACE OF FORMED BODY AND ROUGHENED SURFACE FORMING WORKING TOOL

摘要

PROBLEM TO BE SOLVED: To provide a new and more simple roughened surface forming working method of the surface of a formed body for roughening some part of the surface or the whole surface of the solid formed body into a matte- or satin-like surface and a roughened surface forming working tool employed for use in the method so as to make the conventionally difficult repairing of the glossed surface of a metal formed body to its initial satin-like surface possible.;SOLUTION: By employing the roughened surface forming working tool 2 made by assembling en bloc an abrasive cloth paper and a thrusting body adjacent to each other, a roughened surface corresponding to the tongued and grooved surface made of a large number of abrasive material particles on the abrasive material surface of the abrasive cloth paper 4 on the surface of the formed body is formed by abuttingly thrusting the abrasive material surface of the abrasive cloth paper against the surface of the formed body 1.;COPYRIGHT: (C)2008,JPO&INPIT
