Background

The electric pulse machine tool is a machine tool which completes machining by utilizing an electric pulse technology. The working principle is that high-frequency electric pulse is applied between the workpiece and the tool, so that the electrode on the tool instantaneously generates high energy through discharge and forms a tiny melting area on the surface of the workpiece, thereby realizing the processing and removal of materials. The electric pulse machine tool is mainly used for processing high-hard materials and special-shaped processing, such as metal alloy and the like. Because the electric pulse processing has the advantages of high precision, high efficiency, no thermal influence and the like, the method is widely applied to the precision processing field of manufacturing industry, such as the industries of mould manufacturing, aerospace, medical appliances and the like.

The existing machining process adopts an electric pulse discharge machining process, particularly internal threads, for the thread machining of high-hardness metal materials.

In particular, when a large workpiece is touched, a common electric pulse machine tool cannot be processed due to limited processing stroke and bearing capacity, and workers increase safety risks in the process of carrying and processing. Thus, in view of the above-mentioned phenomena, there is an urgent need to design and produce a portable electric pulse screw-thread electric discharge machining apparatus to meet the needs of practical use.
