Abstract

PURPOSE:To enable to establish high performance magnetic heads by bonding and fixing the raw material bonded on the square pillar block with adhesives to the inside of the tool and shaping the raw material in arc shape. CONSTITUTION:The magnetic head raw material 1 in square pillar shape is contacted at the tip of the block 2 of square pillar, and the tool 3 is provided, in which the bottom and the sides of the block 2 are pushed to the inside formed in rectangle and fixed. The center is pushed on the holes of the both sides of the tool 3, the tail spindle is installed on the table of the shaping machine, and the motor 18 and the bearings supporting the shaft 11 in shaking and interlocking with the motor via the links 17, 19 so that the bearings can be located on the shaft center of the trail spindle in rotary free, are installed on the table of the shaping machine. Further, the tool 3 is shaken via the reception arm 14 fitted to the shaft 11 and the pin 15, allowing the grindstone to form highly accurate arc on the machined surface of the magnetic head raw material 1.
