The invention relates to a device for the electrochemical treatment of metals by means of a vibrating electrode. Said device is provided with a vertically displaceable sleeve (5) in the housing (1, 2, 3). A tool holder (12) is arranged in a vertically vibrating manner in said sleeve and is preferably held by means of two membranes (15, 16) in the sleeve (5) in such a way that said holder can be vertically displaced. The membranes allow for a vertical movement of the tool holder (12) only while no horizontal movements can be carried out.

Abstract:
A method for forming a complex hole (60) through a wall of a structure (40). The complex hole has a smaller cross-sectional area at a first location (68) within the wall and an outer portion (70) with a larger cross-sectional area adjacent a first surface (50) of the wall. The complex hole further has an inner portion (62) extending between the first location and an inlet opening (64) on a second surface of (66) the wall. The method uses an EDM process to automatically first, form an entry hole (65) in the wall extending from the first surface to the first location inside the wall, and second, form the outer portion of the complex hole in a direction moving from the first location inside the wall toward the first surface, and third, form the inner portion of the complex hole.
Abstract:
The invention relates to a method and a device for the electroerosive material machining of a workpiece (3) by means of a longish electrode tool (1). The electrode tool (1) is guided in an electrode guide (15) in which an oval cavity (15a) is embodied. The wire section (1a) in the cavity (15a) is exposed to a magnetic field (18) and can be laterally deviated. The lateral deviation is carried out by an axial movement of the wire section (1b) located in the region of the workpiece (3), in order to produce an optimum working gap between the workpiece (3) and the free end part (1c) of the wire section (1e).
