[0002] Wire cutting is a type of electric spark wire cutting. It uses a continuously moving thin metal wire as an electrode to perform pulse spark discharge to erode metal and cut the workpiece into shape. It is mainly used to process various complex and precise small workpieces. Wire cutting machine tools belong to the category of electrical processing.

[0003] After checking the announcement number: CN214518032U, a slow wire cutting machine tool is disclosed. This technology discloses "including a machine body, the machine body is provided with an observation window, the observation window is provided with a sponge block, the sponge block is fitted with the observation window, the sponge block is slidably connected with the observation window, and the machine body is provided with a driving mechanism for driving the sponge block to slide, etc. This application has the technical effects of being able to facilitate the operator to observe the cutting status of the workpiece and improve work efficiency, etc.";

[0004] With respect to the above-mentioned related technologies, the inventor believes that the existing wire-cutting machine tool structure is not provided with a protective component. When cutting the workpiece, the continuously moving thin metal wire is used as an electrode to perform pulse spark discharge on the workpiece. This cutting method will cause the sparks to jump to the periphery and accidentally injure people. The lack of a protective component makes it inconvenient to perform protection during cutting, which reduces the safety of the wire-cutting machine tool. Secondly, the prior art generally places the workpiece to be cut directly on a placement table for cutting. During the cutting process, the workpiece will move, resulting in inaccurate cutting accuracy. The lack of a positioning component makes it inconvenient to stably position the workpiece during cutting, which reduces the accuracy of the workpiece processed by the wire-cutting machine tool.
