[0002] Wire cutting is the abbreviation of CNC EDM wire cutting. Wire cutting machine tools belong to the category of electrical machining. Its basic physical principle is that free positive ions and electrons accumulate in the field and quickly form an ionized conductive channel. CNC EDM wire cutting is the same as EDM forming processing. It directly uses electrical energy and thermal energy to process the workpiece. It can process various conductive materials that are difficult to process by general cutting methods, such as high-hardness, high-brittleness, high-toughness, and high-heat-sensitive metals or semiconductor materials. Before wire cutting, the workpiece needs to be fixed to facilitate precise wire cutting of the workpiece.
