How much do you know about wire cutting? Can precision parts be processed?

Usually, people often understand CNC machining, three-axis machining, etc. In fact, in the common machining methods, people have forgotten a special machining method, that is, EDM wire cutting machine, referred to as wire cutting Processing.

The wire EDM machine tool uses electrode wire (molybdenum wire, tungsten-molybdenum wire) as the tool electrode, and the working fluid as the medium. Under the action of high-frequency pulse power, a spark discharge is formed between the tool electrode and the processed workpiece, and the discharge channel instantly generates high temperature , Making the surface of the workpiece melt or even vaporize, so that the electrode wire moves along a predetermined trajectory, so as to achieve the purpose of processing the workpiece.

Wire cutting can be used to process precision parts. It has the advantages of small processing margin, high processing accuracy, and short production cycle. It is widely used in the mechanical parts production industry. It is mainly used for processing various complex and precise small workpieces, such as fixed plates, discharge plates, etc., forming tools, prototypes, plastic molds, hobbing cutters, precision parts (including large tapers, equal cones, unequal cones, etc. (Complex surfaces such as upper and lower irregular shapes), large molds with large load and large thickness, metal electrodes for EDM processing, various fine holes, narrow slits, arbitrary curves, etc. Although the machining of wire-cut precision parts is not comparable to CNC machining and other methods, individual uses still have their unique features.
