  • Device for feed control of electrode-tool in spark erosion machines
    Patent number: 4891486
    Abstract: A device for electrode-tool feed control in electroerosion machines includes a power source (1) equipped with reservoir capacitors, one output of the power source (1) is connected to a workpiece (2) and the other to the electrode-tool (3), a threshold circuit (4), and one of the inputs of a switching device (5). The output of the threshold circuit (4) is connected to an electronic switch (6) and to the second input of the switching device (5) whose output is connected to an amplifier (7). The output of the amplifier (7) is connected to a diode bridge (8) of a converter unit (9), connected in series with a primary winding (10) of a transformer (11) of this converter unit (9) and to an AC supply line (12). The output of the electronic switch (6) is connected to the other diode bridge (13) of the converter unit (9) and to a second primary winding (14) of the transformer ( 11) of this converter unit (9).
