[0001] The invention relates to the technical field of numerically controlled machine tools, and in particular to an electric spark wire cutting numerically controlled machine tool for producing end covers. Background Art

[0002] Wire EDM is also known as wire cutting. Its basic working principle is to use a continuously moving thin metal wire (called electrode wire) as an electrode to perform pulse spark discharge to erode metal and cut the workpiece into shape. Wire EDM technology is a special processing technology. It is different from traditional processing technology that requires mechanical force and mechanical energy to cut. It mainly uses electrical energy to process materials. Therefore, wire EDM technology is not limited by material properties and can process any hardness, strength, and brittle materials. Wire cutting is to process parts through the discharge principle of electric sparks. The workpiece is connected to the positive electrode of the pulse power supply, and molybdenum wire or copper wire is used as the cutting wire.

An operating method of a CNC wire-cut electric discharge machine tool for producing end caps, applicable to the CNC wire-cut electric discharge machine tool for producing end caps as claimed in any one of claims 1 to 9, characterized in that: The steps include: S1. Place the object to be processed in the processing water pool, extract the cutting fluid from the water tank through the liquid supply end, and pour it into the processing water pool; S2, start the lifting arm to control the height of the cutting head, and use the cutting head to cut the material. After cutting, there will be a lot of debris in the cutting fluid inside the processing pool, and the waste water will be poured into the box; S3. The cutting waste fluid is filtered multiple times through the purification mechanism and stored centrally to facilitate subsequent secondary use.
