摘要

P THIS SECURITY IN PARTICULAR ALLOWS MECHANICALLY SLOW DOWN THE WHEEL BEARER 2 AFTER ITS QUICK APPROACH TO THE WORKPIECE W, BY THE SERVOMOTOR 6 AND THE FEED CONTROL SCREW, IN ORDER TO PREVENT THE MILL 3 HIGH SPEED WORKPIECE IN THE EVENT OF A SYSTEM FAILURE WHICH, NEAR THE GRINDING WHEEL, NORMALLY REDUCES THE FAST FORWARD SPEED OF THE WHEEL BEARER TO A SLOW RANGE OF THROUGHPUT THEN FINISHING. SAFETY INCLUDES A HYDRAULIC CYLINDER 17 MOUNTED FIXED ON THE GRINDER 2 AND TO WHICH THE PISTON 18 IS ATTACHED BY ITS ROD 20 AND WITH A FREEDOM OF MOVEMENT 1 - CORRESPONDING TO THE AMPLITUDE OF FAST ADVANCE - TO A REFERENCE PLATE 25. THE RELATIVE MOVEMENT OF THE CYLINDER AND THE PISTON BRAKES THE MECHANISM IN THE EVENT OF A FAILURE OF THE SAID SYSTEM. /P
