Title:
POWER SUPPLY SYSTEM FOR WIRE ELECTRIC DISCHARGE MACHINING
Document Type and Number:
WIPO Patent Application WO/2012/011545
Kind Code:
A1
Abstract:
A power supply system for wire electric discharge machining comprises a first power supply circuit (10) and a second power supply circuit (20). The first power supply circuit applies, to the machining gap, a voltage that induces a discharge. The second power supply circuit, which includes a low inductance line (30), supplies, to the machining gap, a current (i2) that contributes to the machining. A blocking diode (41) is series-connected between the low inductance line and the machining gap. There is provided a container (50) that has a contact surface (56) contacting with the blocking diode and that contains cooling liquid.
