Slow wire machining is a kind of EDM technology, usually used in the production of metal molds. In this process, a thin and charged wire is used to create an electrical discharge between the workpiece and the electrode, consuming the material on the surface of the workpiece, thus achieving precise cutting of the workpiece.
Compared with traditional machining, the advantage of slow wire processing is that it can achieve high precision, small size, complex shape parts processing, and can handle high hardness metal materials. At the same time, because there is no direct contact during the cutting process, there will be no mechanical deformation or scratching problems.

It should be noted that slow wire processing needs to be combined with CAD/CAM software for early process planning and programming to ensure that the cut product meets the requirements. In addition, for the processing of large or complex parts, it is also necessary to consider how to stabilize and manage parameters such as tension, speed and electrical conductivity of the silk wire to ensure processing quality and efficiency.
