BEVELLING METHOD

摘要

PURPOSE:To improve the machining accuracy by pressure contacting the outer edge section of machining face of work such as a floppy disc head and the like with the polishing tape wound over a rotary drum then rotating the drum in the uppercut direction to perform bevelling. CONSTITUTION:A work A is spun around the spinning axis P normal to the machining face 1 and rolled on the face F parallel with the axis of rotary drum 40 while containing said axis P. The work A is arranged displaceably in the direction of said axis P and energized toward the polishing face 21 such that the outer edge section 2 of the machining face 1 will contact continuously with the polishing face 21 then the rotary drum 40 is rotated in the uppercut direction thus to perform bevelling of uppercut by means of a polishing tape.
