Abstract: 1317474 Grinding LITTON INDUSTRIES Inc 9 June 1970 [10 June 1969] 27734/70 Heading B3D A cylindrical grinding machine for effecting removal of stock from a rotating workpiece W, Fig. 1, having portions A, B, C, D, of different diameter to be machined, comprises drive means MTR5 for rotating the workpiece, feed means for progressively relatively transversely feeding the workpiece and a grinding wheel 23, and means for controlling the relation of the speed of rotation of a workpiece portion being machined and the relative transverse feeding movement rate. The grinding wheel 23 is carried by a wheelhead 15 movable towards and from a workpiece W mounted between a headstock 13 and tailstock 14 on a support 12 longitudinally movable on a bed 11, the headstock having a motor MTR5 for rotating the workpiece. The feed mechanism for advancing the wheelhead 15 consists of a feed screw 20 engaging a worm-wheel 24 on a shaft 25 mounted in the wheelhead, the screw being axially movable by a piston-and-cylinder device 21, 22 and rotatable by a wheel 34 engaging a worm 38 on a shaft 37, in turn, rotatable by a worm-and-wheel 42, 43 actuated by a ratchet drive mechanism 40. The shaft 25 is also rotatable through a worm-and-wheel 26, 27 and gearing 34, 35, 36 from a piston-andcylinder device 30, 31 or by a hand wheel 29. The supply of hydraulic fluid to the cylinders 22, 30 is controlled by an hydraulic circuit which includes a number of valves and three throttle valves 86, 89, 90, the valves being under the control of a panel 60 associated with a tape reader whereby fast feed of the grinding wheel is controlled by the flow through throttle valve 86, intermediate feed by the flow through throttle valve 86 and throttle valve 90, and the slow feed by the flow through throttle valve 86 and throttle valve 89. A diameter range switch is incorporated in the circuit so that the feed rates are related to ranges of diameter of the workpiece. The switch also controls the frequency supplied to the motor MTR5, which is of squirrel cage type, so that the speed of rotation of the workpiece is also relative to the diameter range. The output from a caliper which measures the diameter of the portion of the workpiece being ground is used to ensure that the feed rate and speed of rotation of the workpiece are correct for that diameter of workpiece.
