| 摘要 |
<p>The invention provides an apparatus and a method of generating machining pulses for electrical discharge machining by discharge of at least one line (6a-6d) applying a voltage to a working gap formed between a machining electrode (2) and a workpiece (1), comprising the steps of: charging the line (6a-6d) via a first charging circuit (14, 15, 16, 17) by a voltage source (13), discharging the line (6a-6d) after ignition of the spark gap directly via a diode (5a-5d), without impedance matching, at the working gap, and recharging the line (6a-6d) after a predefined pulse-off time.</p> |
