Abstract

1440448 Electro-erosion WICKMAN MACHINE TOOL SALES Ltd 7 Jan 1974 [9 Jan 1973] 1205/73 Heading B3V [Also in Division G3] Machining pulses are supplied by a generator 23 to an EDM electrode 10 and workpiece 17 in a dielectric fluid tank 18. The gap is measured by a sensor 22 feeding a signal to a comparator and oscillator 19 which supplies drive pulses to a stepping motor 12 in order to regulate the gap size. The motor 12 is connected to the electrode 10 through gears 13, a lead screw 14, nut 15 and a slide 11. When the motor stops, a clutch or brake 16 locks the gears 13 and supports the weight of the slide 11 and electrode 10. The electrode can be vibrated by reversing the polarity of the drive pulses. The required and actual distances moved by the electrode may be preset and displayed 24, 25.
