The wire cut edm machine is wire-cut electric discharge machine, which belongs to an electric machining machine tool. Here we need to know the principle of EDM first. The high temperature generated by spark discharge can cause partial oxidation and corrosion of the metal. When the local metal is melted and corroded, use cold water to wash it, so as to have the EDM machine tool. Wire cut Edm machine was actually invented by the former Soviet Union, and China was the first country to apply WEDM to industrial production.

According to wire speed, wire cut Edm machine can be divided into high speed wire cut Edm machine, medium speed wire cut Edm machine and low speed wire cut Edm machine. The high speed wire cut Edm machine, also known as the reciprocating wire EDM machine,whihc uses molybdenum wire as the tool electrode, and its wire speed is 6~12 mm/s. It is an original machine in China, with fast cutting speed and suitable for processing large thickness workpiece. It is a widely used machine tool in the market. On the basis of fast wire cutting, frequency conversion cutting has been carried out for many times, resulting in a mediumspeed wire cut Edm machinel, which is a new technology developed in recent years. The low speed wire cut Edmmachine, also known as the low-speed wire cutting machine, which uses copper wire as a tool electrode, and generally moves in one direction at a speed of less than 0.2mm/s. Therefore,it is not suitable for processing large thickness workpiece.

Regardless of the processing accuracy requirements, I strongly recommend high speed wire cut Edm machines for users who want to buy cheap wire cut Edm machine. Because the machine tool has simple structure, low technical content and low cost, the high speed wire cut Edm machine is the cheapest of the three kinds of WEDM machines.

With the gradual improvement of large taper and large thickness cutting technology and the continuous improvement of machining accuracy, the machining thickness of high speed wire cut Edm machine can exceed 1000mm. At the same time, the cost of machine tools is low and the demand is large, which makes the number of high speed wire cut Edm machine grow rapidly in order to meet the needs of most domestic and foreign customers.
