Abstract: A power supply is provided for electrodischarge wire machining in which high-frequency AC voltage is applied between a wire electrode and a workpiece. A power supply device includes a high-frequency AC oscillator and amplifier circuit (4) and a pulse source (5) for applying high-frequency AC voltage intermittently between a wire electrode (1a) and a workpiece (2). In the electrodischarge wire machining using this power supply, the vibration of the wire electrode (1a) due to electrostatic force between the wire electrode (1a) and the workpiece (2) is suppressed, thus improving the straightness of the machined surface and reducing surface roughness.

Abstract: A power supply unit for electrodischarge machining applies voltage of positive and negative polarities across a gap between an electrode (1) and a workpiece (2). The power supply comprises control means (8) that applies first voltage pulses across the gap for a period (T1), waits a period (t) after the period (T1) so as to prevent switching means from damage, and applies second voltage pulses of the polarity opposite to the first voltage pulses for a period (T2a) until the voltage across the gap reaches a predetermined voltage below the voltage (Va) at which a discharge begins. Since the remaining voltage across the gap is thus removed quickly, steady and quality machining can be carried out.

The hard coating is a good coating containing crystallite particles.

Abstract: A power source apparatus for electrical discharge machining, adapted to accurately detect the starting of normal electric discharge between electrodes, and switch an auxiliary power source to a primary power source. A switch (3) is turned on by a signal S1 from a control unit to apply a voltage of an auxiliary power source (1) between a work (5) and a machining electrode (6), and the voltage Vw between the electrode starts increasing. When the insulation recovery is sufficient, a partial voltage Vwd at the node between voltage dividing resistors (7, 8) exceeds a reference voltage V1, and the level of an output C1 from a comparator (9) becomes high, so that a SR flip-flop (14) is set. When the voltage Vw between the electrodes decreases due to the generation of electric discharge, the partial voltage Vwd becomes lower than a reference voltage V2, and the level of an output C2 from a comparator (10) becomes low, so that the level of the inverted signal C3 from an inverter (13) becomes high. Consequently, the SR flip-flop (14) is reset, and the level of an output C4 changes from high to low. A monostable multivibrator (15) detects the fall of the output C4 and outputs a signal C5 indicating the detection of a discharge.

Abstract: The electric circuit for electroerosion machining comprises erosif discharge delivery means (1) and pre-ignition means (6-12). The pre-ignition means, provided with a transformer (6) and a Zener diode (3), comprise a clipper branch (11, 12) also with a Zener diode. In addition, power regulating means (14, 15, 22, 23, 24) are connected to limit the pre-ignition pulse current as a functionof the clipper current, measured by the voltage drop at the terminals of a resistance (12) in series with the clipper Zener diode (11). The arrangement of the pre-ignition means relates mainly to the control of electric and geometric parameters related to the pre-ignition and to the general operation of the machining unit.
