Linear cutting machine tools can be divided into high-speed, low-speed and medium-speed wire-moving machine tools. They are used to cut the workpiece by producing wire cut electrical discharge by the machine tool in the process of work. There are similarities, as well as differences. Their differences lie in workpiece quality, rather than the wire-moving speed in the machining process. Next, we'll introduce a medium-speed wire-moving machine tool with the best machining effect in detail, and now let's take a look at the cutting process of the workpiece.
1. Principle of medium-speed wire-moving cutting workpiece
At the time of workpiece machining, the quality of the workpiece machined is between high-speed and low-speed wire-moving technologies, so it is called as medium-speed wire-moving technology. Such cutting technology uses the molybdenum wire that continuously moves as electrode, which produces pulse current under certain AC voltage, and then results in discharge spark, and such spark can erode the metal, so that it can make some metal workpieces cut into certain shapes.
2. General process of medium-speed wire-moving cutting
When cutting the workpiece, it is usually to control the machine tools through digital programming and then complete the cutting process of the workpiece. In the process of workpiece machining, it is necessary to set some parameters for programming, such as high-frequency pulse width and wire-moving speed, etc. After these parameters are set, programming is equivalent to a control system, which will control the entire machining process of workpiece. In the process of workpiece cutting, it can be used to cut for multiple times. During cutting, its running speed is not slower than high-speed wire-moving cutting, and to be precise, its speed is even faster than high-speed wire-moving cutting.
When cutting, the cutting speed can be adjusted according to parameter settings. The medium-speed wire-moving technology can be used for multiple cutting, which is somewhat similar to the working principle of low-speed wire-moving technology. Only after multiple cutting can the cutting speed be reduced, and the cutting quality falls between high-speed and low-speed wire-moving technologies, but its efficiency is the highest among the three.
