Abstract

1,272,994. Grinding machines. HEALD MACHINE CO. 14 May, 1969, No. 24656/69. Heading B3D. A grinding machine comprises a base 11 on which are mounted a workhead 12 and a wheelhead 33, a main stepping motor 37 and a screw 36 for producing relative movement between the workhead and the wheelhead, control means 46 for introducing electrical pulses to the stepping motor 37 to produce a grinding cycle, and a secondary stepping motor also connected to the control means 46 to receive the same electrical pulses as the motor 37. An indicator 51 for indicating machine element positions is driven by the secondary stepping motor, and switches are provided which are operated by a potentiometer for operation at predetermined pulse counts for controlling operation of the machine. In the machine described, the workhead 12 mounts a workpiece 16 and includes a pneumatic gauge 18 operating switches 19, 21, 22 which respectively indicate the dressing size, the size at the end of a finish grind, and the final size of the workpiece. The wheelhead includes a wheel 35, and is mounted on a table 25 for transverse reciprocation under the action of the stepping motor 37. An adjustable size control 38 and a dress stop finger 29 engage with stops 31, 28 carried by a compensation slide 26 on the base 11 to perform automatic dressing of the wheel during a grinding cycle. The secondary stepping motor has a rotating shaft which drives the indicator 51 to indicate the position of the table 25. The shaft also drives one component of the potentiometer so that the voltage from the potentiometer is also related to the position of the table 25. Coarse compensation, 54, cycle start, 56, worm-wheel, 58, and new wheel, 52, switches, each including an adjustable potentiometer for delivering a predetermined set voltage, a voltage comparator in which the set voltage is compared with that from the first potentiometer, a numerical indicator indicating the set voltage, and a relay, are connected in such a way that when the potentiometer voltage equals the set voltage, i.e. when the numerical indicator 51 tallies with the preset value, the appropriate switch is operated and a corresponding cycle initiated.
