Estimating the term…
The invention pertains to a method and a device for die sinking and wire-cutting workpieces by means of electrical discharge machining. A machine frame (10) as well as a worktank (9) and a lower guide head (5) form a stationary unit referred to the main axis directions X, Y. The workpiece (2) is immersed in the worktank (9) and moved in the horizontal plane by means of the X/Y main axis drive (14). An upper guide head (4) also forms part of the stationary unit or can be moved by means of a Z drive (16) and/or a U/V drive (15). The lower guide head may also be designed such that it can be vertically moved by means of a lower Z drive (17). This concept is particularly suitable for producing microscopic components by means of electrical discharge machining and as a multielectrode machine that processes workpieces simultaneously or sequentially.
A method for processing workpieces by electric discharge machining, with at least one electrode which is guided in guide heads above and below the working zone, said method comprising the steps of:
An apparatus for processing workpieces by electrical discharge machining, with at least one processing electrode, wherein a workpiece is moved in horizontal X/Y main axis directions and simultaneously eroded by at least one processing electrode, said apparatus comprising:
