At present, the processing of the mold industry is mainly: general milling machines (rough, drilling unimportant holes), CNC milling machines (computer gongs, CNC), grinding machines, spark machines, turret milling machine factory and so on.

Let's take a look at the principle of turret milling machine factory: It is through a molybdenum wire to do one end of the electrode and move back and forth, the other electrode is the workpiece, in the processing of molybdenum wire and the workpiece is not in direct contact, but between the formation of a certain gap to form a short circuit, through the heat released during the short circuit to melt the workpiece. The gap between the molybdenum wire and the workpiece is what we usually call the spark position.

Application: Generally, it is necessary to do inserts on the internal mold, or the shape of the workpiece is not processed by the computer, nor can it be processed by the grinder, and it is necessary to carry out line cutting, as well as the top pinhole, cylinder hole, etc. It is to divide a workpiece into two parts by discharge, one is scrap, and the other is what we want.

With the progress of the manufacturing industry, CNC machining has gradually dominated the traditional machining, employees of the special processing understanding and understanding of the need for more and more large, for CNC technology we can be more easily understood as computer control principle, but for the understanding of electrical machining technology is less, it is necessary to discuss CNC electrical machining equipment with you, Understand the pillars of future industrial success. Traditional machining has a long history, it has played a great role in human production technology and material civilization. However, with the progress of human science and technology, complex process production has seriously restricted the development of productive forces. It was not until 1943 that the former Soviet Union Lazarinkov got rid of the traditional cutting method. Using electricity to cut metal. It generates a spark discharge between the negatively charged tool electrode and the positively charged workpiece, resulting in instantaneous high temperature, so that the local metal is melted and vaporized and corroded, and the effect of "soft and rigid" is obtained.

Second, the classification and principle of electrical machining

According to the principle of discharge machining and the energy function, it can be roughly divided into: EDM, electrochemical machining, electron beam machining, ion beam machining, plasma arc machining, etc. Electrical discharge machining, also known as discharge machining, referred to as EDM, is a processing method that continuously generates pulsed spark discharge between the tool electrode and the workpiece, and relies on local instantaneous high temperature to corrode the metal. Electrochemical machining is the process of dissolving metal ions with electrolytic solutions. Electron beam machining is a melting and gasification process in the welding process. Ion beam machining is a kind of kinetic energy machining by etching injection for atom impact. Plasma arc processing is a kind of processing method which is melted by coating thermal energy during spraying process.
