Abstract

The embodiment of the invention provides a preparation method of a multi-material laminated electrode. The method comprises the steps of conducting lamination combination on a first preset amount of first metal foil and a second preset amount of second metal foil to form a metal lamination layer, wherein the electrical resistivity of the first metal foil is larger than that of the second metal foil; conducting primary processing treatment on the metal lamination layer; adopting preset parameters for conducting secondary processing treatment on the metal lamination layer to form an electrode blank; conducting electric-spark processing treatment on the electrode blank to form a preset working face profile and obtain the target electrode. The laminated electrode with the length being severaldozen millimeters can be simply and quickly prepared. Compared with micro-column-shaped electrodes and thin-slice electrodes, the laminated electrode has longer service life, multiple micro-trenches can be processed at a time, and the processing efficiency is higher; the laminated electrode is large in cross section dimension, strong in anti-jamming capability, high in processing stability and very suitable for electric-spark processing of a large batch of blind micro-trenches.

Description

technical field [0001] The invention relates to the technical field of electrode processing, in particular to a method for preparing a multi-material laminated electrode. Background technique [0002] Micro-EDM is non-contact processing, which has the advantages of no macroscopic cutting force and can process any conductive material. It is an important technical means to prepare surface blind micro-groove structures on difficult-to-machine materials. At present, micro-columnar electrodes are mainly used layer by layer. Obtained by scanning discharge machining and sheet electrode reciprocating discharge machining. However, in the process of EDM, tool electrodes are inevitably worn out, especially the tiny electrodes used for microstructure processing are more worn out, which reduces the service life of tool electrodes and makes it difficult to process blind micro-surfaces in large quantities for a long time. Trench structure. Contents of the invention [0003] In view of ...
