Title:
POWER-FEEDING DEVICE FOR A WIRE-CUT ELECTRIC SPARK MACHINE
Document Type and Number:
WIPO Patent Application WO/1987/005242
Kind Code:
A1
Abstract:
A power-feeding device for a wire-cut electric spark machine, comprising a wire electrode guide (3), a first power-feeding portion (51) provided along a direction of expansion of a wire electrode (1) for wire-cut discharge processing, and a second power-feeding portion (52) which is provided along a direction of expansion of the wire electrode (1) and which is capable of moving in a direction of intersecting the wire electrode (1), wherein the wire electrode (1) is selectively connected to the first power-feeding portion (51) or to the second power-feeding portion (52). Or, a power-feeding device for a wire-cut electric spark machine, comprising a wire electrode guide (3), a third power-feeding portion (53) and a fourth power-feeding portion (54) that are provided while maintaining a small distance relative to each other with the wire electrode (1) for wire-cut discharge processing interposed therebetween, and a wire electrode direction changing means (4) for changing the direction of expansion of the wire electrode (1), wherein the wire electrode (1) is selectively connected to the third power-feeding portion (53) or to the fourth power-feeding portion (54).
