Abstract: 832,146. Grinding. SVENSKA KULLAGERFABRIKEN A.B. June 16, 1958 [June 24, 1957], No. 19243/58. Class 60. A method of grinding a succession of similar workpieces comprises automatically modifying the depth of dressing of a grinding wheel between rough and finish grinding in such a way that when the finish grinding time on the previously-ground workpiece is too short, the dressing depth is increased, and when it is too long, the dressing depth is decreased. During finish grinding or " spark-out " of a workpiece, a pneumatic or electric time relay 10 is opened to permit the passage of hydraulic or pneumatic fluid, the pressure of which can be varied by a valve 110, to the lower end of a piston-andcylinder device 12, 18. The rod 16 of the piston has an enlargement 13 which has chamfered ends 14, 15 arranged to co-operate with rollers 213a, 213b on the ends of rods 212a, 212b on valves 211a, 211b. At the termination of finish grinding, and, depending upon whether the correct feed has been chosen or the wear of the wheel correctly estimated and the finish grinding time is therefore too long, correct, or too short, the enlargement 13 will be positioned opposite the roller 213a, between the rollers, or opposite the roller 213h, respectively. Hydraulic or pneumatic fluid supplied after finish grinding by pipes 210a, 210b to the valves 211a, 211b will, if one of the valves is opened by the enlargement, displace a piston 27a or 27b to displace a pawl 25a or 25b to move a ratchet wheel 20 in one direction or the other ; screws 29a, 29b control the amount of movement of the pawls. The ratchet wheel has a keyway 22 which is wider than the key 23 on a shaft 21 feeding the dressing diamond so that it is not until there have been three consecutive movements of either pawl 25a or pawl 25b that movement of the ratchet wheel is transferred to the shaft 21 of the dressing diamond.
