Abstract

PURPOSE:To strictly manage the finishing accuracy of a grinding by forming an insulating protecting layer of a magnetic circuit, removing the insulating protecting layer by a thickness not to reach the magnetic circuit, forming a projecting part and a flat part, next, grinding the projecting part, and allowing it to be flat. CONSTITUTION:An insulating protecting layer 16 is formed on a magnetic circuit 19, the insulating protecting layer 16 is removed by the thickness not to reach the magnetic circuit 19 above the height of a level difference part 16a so as to leave the level difference part 16a of the insulating protecting layer 16 formed in reflecting the mound of a gap part side in the magnetic circuit 19 and to leave a flat point in the vicinity, and a projecting part 16b and the flat part are formed. Next, the projecting part 16b is ground made flat, thereafter, a protecting board 18 is bonded on the insulating protecting layer 16 by an adhesive, and thereafter, a sliding surface grinding is executed up to the vicinity of the point where the level difference part 16a exists. Thus, at the time of allowing the insulating protecting layer 16 to be flat, even when a fluctuating is generated in the grinding quantity, matters that the magnetic circuit 19 is scarred by mistake, etc., can be avoided, and the finishing accuracy of the grinding can be strictly managed.
