Abstract (en)

Chamfering a longitudinally curved slot corner (3) which is formed by a front surface (1c) of a slotted member and longitudinally curved surface (2a) of the slotted member (1) defining a slot (2) is executed as follows. First, the slotted member (1) is held between an upper holder (5) and a lower holder (6). Next, a backup plate (8) whose upper surface (8a) is curved in every plane normal to the longitudinal direction of the backup plate (8) is placed in the slot (2) and a grinding belt (7) is applied to the upper surface (8a) of the backup plate (8) so as to travel in the slot (2). Then, the upper and lower holders (5, 6) are relatively shifted so that the slotted member (1) is tilted, thereby pushing the grinding belt (7) in running against the longitudinally curved slot corner (3) and chamfering it. Since the grinding belt (7) follows the curvature of the curved upper surface (8a) of the backup plate (8), the grinding belt (7) can fit the longitudinally curved slot corner (3) and grind it.
