Description

Technical Field

[0001] The utility model relates to the technical field of numerically controlled wire-cutting machine tools, in particular to a numerically controlled wire-cutting machine tool with the function of adjusting the wire-cutting pitch. Background Art

[0002] Wire cutting machine is also a kind of EDM wire cutting machine. Its working principle is to use continuously moving molybdenum wire (called electrode wire) as electrode to perform pulse spark discharge to erode metal and cut the workpiece into shape. Its wire speed and workpiece quality are between fast wire cutting and slow wire cutting, so it is called medium wire cutting. The wire cutting machine device on the market has no lubrication mechanism, and cannot perform timely lubrication and maintenance on the device, which will cause the device to jam during operation. There is no waste collection mechanism, and the working platform of the device cannot be guaranteed to be clean, which will reduce the working efficiency of the device.
