METHOD AND ABRASIVE DISK FOR MACHINING SIDES OF PLATES Russian patent published in 1997 - IPC

FIELD: mechanical engineering. SUBSTANCE: device comprises base 1, rotatable table 2 with a device for locking plates that is mounted on the base, and lever 3 with drive 4 whose shaft has abrasive grinding disk 5. Grinding disk 5 is made up as housing 6 and disks 7,8, and 9 which form a shaped surface together with side portions 10 and 11 and bottom portion 12 for machining the sides of plates. The side portions of the shaped surface posses greater abrasive capability and hardness whereas the bottom portion posses lesser ones. The shaped portions may be adjusted in width. The disks may be secured to the housing by any method known, e.g. by a heat adhesion glue. Plate 13 to be machined is mounted on rotatable table 2 and set in rotation. Abrasive disk 5 is brought to the side of the plate and also set in rotation. EFFECT: enhanced efficiency. 2 cl, 2 dwg
