Title:
SMALL-HOLE ELECTRIC DISCHARGE MACHINING MACHINE
Document Type and Number:
WIPO Patent Application WO/2016/199302
Kind Code:
A1
Abstract:
This small-hole electric discharge machining machine (30) for electric discharge machining of a workpiece (20) by use of a rod-like or pipe-like electrode (10) is equipped with: a first support part (7) for supporting the base side of the electrode (10); a second support part (8) for supporting the tip side of the electrode (10); and an intermediate guide device (50) that is disposed between the first support part (7) and the second support part (8), and guides the electrode (10). The intermediate guide device (50) is equipped with: a guide part (51) that has an open form and a closed form, and guides the electrode (10) when in the closed form; a driving means (55) for causing the guide part (51) to transition between the open form and the closed form; and a biasing means (59) for biasing the guide part (51) in the closing direction when the guide part (51) is in the closed form.
