DEVICE FOR POLISHING CURVILINEAR BLANKS Russian patent published in 1995 - IPC

FIELD: machine tool manufacture. SUBSTANCE: blank 1 is installed into the clamping mechanism of carriage 7. Drive 9 is switched on, and carriage 7 feeds blank 1 into the zone of abrasive tool 3. The mechanisms of rotation and of elastic clamp are switched on and abrasive tool 3 is pressed to blank 1. Carriage 7 performs the reciprocal motion relative to abrasive tool 3, that is the processing is exercised in short lines. Depending on the position of blank 1, that is with its convex or concave side towards carriage 7, position pickup 16 has or does not have, correspondingly, the contact with blank 1. If the contact is available, position pickup 16 electrically passes the instruction to drive 19 through pneumatic distributor 20. The shield turns, and the cuttings get into the collector of cuttings 12. When the contact is not available, the electric circuit is broken and drive 19 turns the shield to the opposite side and the cuttings get into another collector of cuttings. EFFECT: economy of metal at the expense of collecting the polishing by-products according to the brand. 1 cl, 3 dwg
