Description

Technical Field

[0001] The utility model relates to the technical field of wire cutting machine tools, in particular to a wire cutting machine tool for processing metal products. Background Art

[0002] Wire cutting machine is an electric machining machine that cuts metals, especially hard materials and parts with complex shapes, by electro-erosion through molybdenum wire or copper wire. Its working principle is to use a continuously moving thin metal wire (called electrode wire) as an electrode to perform pulsed spark discharge on the workpiece, thereby removing the metal and cutting it into shape. The wire cutting machine has a component that drives the clamping part to move or a component that drives the fixture to move. During the wire cutting process, different parts have different shapes and need to be clamped at different positions. Using a single fixed fixture is not conducive to adjusting the position of the clamping position and has low adaptability. Utility Model Content
