Embodiment Construction

[0039] FIG. 1 shows a section of the wire delivery system of an EDM machine. The wire transport system transports the wire electrode 2 through the working area of ​​the EDM machine, in which a spark discharge is generated by means of the wire electrode 2 , thereby removing material from the workpiece. The wire electrode 2 also undergoes material removal, so that the wire electrode 2 is worn out in the working area even for a short time so that it cannot be used for workpiece machining. For this reason, the wire electrode 2 is continuously guided through the working area and then treated in the treatment area during the machining of the workpiece. Located in the disposal area is a wire cutting device 3 which cuts the used wire electrode 2 into wire segments and collects the wire segments in a disposal container 4 for subsequent disposal.

[0040] FIG. 1 shows the wire delivery system of the wire extraction device 5 , which pulls the wire electrode 2 through the working area an...

Abstract

The invention relates to a wire cutting device (3) for an EDM machine, having a wire extraction device (5), which moves a wire electrode (2) into the cutting zone (8) of the EDM machine in a feed direction; and having A deflection unit (17) in order to deflect the wire electrode (2) traveling into the cutting zone (8) in the feed direction (Z) from the feed direction (Z) into the cutting zone, wherein at least one cutting edge acts the wire electrode (2) in the cutting area to cut it.

Description

technical field [0001] The present invention generally relates to the field of electrical discharge machining, ie machine tools in which an electrical discharge between a wire or strip tool electrode and a workpiece results in material removal from the workpiece. In particular, the invention relates to a wire conveying system for conveying said wire or strip electrodes through an EDM machine and a wire cutting device for severing a wire electrode in a treatment area after the working area of ​​the EDM machine . The invention also relates to a method for cutting such wire electrodes. Background technique [0002] In electrical discharge machining, innumerable individual unstable electrical discharges occur between the tool electrode and the workpiece in a dielectric fluid, separated in space and time from each other. Removal is based on extreme localized heating at the location of the spark discharge, during which material is vaporized. EDM machines of the type just mentio...
