Abstract

1,174,125. Truing grinding wheels. CHURCHILL MACHINE TOOL CO. Ltd. 10 July, 1968 [14 July, 1967], No. 32561/67. Heading B3D. A method of maintaining a dressing tool 4 at a substantially constant distance from the periphery of a grinding wheel 1 comprises continuously detecting reduction of the diameter of the wheel during a grinding operation, and moving the tool towards the wheel as a result of such reduction. In apparatus for carrying out the method, the tool 4, in the form of a diamond, is movable relative to a support 3 by a worm-and-wheel device 5 driven from a motor 6. The motor is operated by a control unit 8 connected by a fluid pipe 7 to an orifice adjacent the periphery of the wheel 1. As the wheel wears, the reduction in diameter causes a pressure drop at the orifice and the unit 8 operates the motor to move the orifice and tool towards the wheel. A potentiometer 9 is mounted on the support 3 and is connected with a unit 10 controlling the speed of a motor 2 driving the grinding wheel so that the peripheral speed of the grinding wheel remains constant
