Abstract
An electrode guide and a method for the spark-erosion of workpieces are disclosed. The electrode guide (1), consisting of a two-piece prism-shaped (2, 3) guide with a pretensioning device (6), enables an electrode (4) to be guided in a play-free manner, thus allowing the production of bores that is accurate to within 1 μm. A pivoting device (10) for pivoting the electrode guide and an alignment device (14) for the parallel displacement of the electrode guide (1) are also provided, enabling the production of conical bores.
Claims24
An electrode guide for an electrode in a spark-erosion machine, said guide comprising;
- a holding component and a pressure component;
- a grooved recess configured in the holding component and the pressure component being pre-tensioned against the holding component by a pre-tensioning device and the electrode being arranged and guided in a play-free manner between the pressure component and the holding component;
- and
- the electrode arranged in a rotating manner.
