Abstract

PURPOSE:To automatically and uniformly machine a negative land of a circumferential surface on a chip edge, by moving the chip linearly relative to a grind stone and rotating it a prescribed angle. CONSTITUTION:Part of the grinding wheel 78 is projected into an opening 7 formed between a platen 4 and a stylus 5. On one end of the platen 4 is provided a work holder 35. While the chip W clamped by the holder 3 is reciprocated along the upper surface of the platen 4 by the action of a cylinder 28 with the chip W abutted on the stylus 5, it is moved linearly along the opening 7, so that the linear part of the edge surface of the chip W is ground by th grinding wheel 78. During the passage of the chip W through the opening 7, the holder 35 is rotated a prescribed angle by the action of a pulse motor 52 to grind the angle of the edge surface of the chip W, so that the negative land of a circumferetial surface on the chip edge is automatically and uniformly machined.
