Description

Technical Field

[0001] The invention relates to the field of mold production, in particular to a slow-feed wire cutting machine. Background Art

[0002] Wire cutting is a type of electric spark wire cutting, which uses 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. It is mainly used to process various complex and precise small workpieces;

[0003] When the wire cutting machine is cutting the mold, since the mold being cut is generally small in size, it is very troublesome to fix the mold. In addition, the clamping speed of the small mold is slow. At the same time, the mold needs to be completely immersed in water during cutting. Therefore, a large amount of water needs to be poured into the cutting machine before cutting. The introduction of water takes a certain amount of time, which in turn affects the production efficiency of the entire cutting machine. At the same time, the filtration speed of the water body after cutting is slow. Summary of the invention
