[0002] Wire cutting machine tools belong to the category of electrical machining. Their main working principle is to use a moving (molybdenum wire, copper wire or alloy wire) as an electrode wire and rely on pulse electric spark discharge between the electrode wire and the workpiece. When the heat generated by the discharge of the metal cutting wire is greater than the melting point of the workpiece material, the high temperature generated by the metal cutting wire causes the workpiece to melt or vaporize, forming a cut, thereby achieving the purpose of cutting the workpiece.

When cutting a workpiece, the metal cutting wire is generally installed on the upper wire rack and the lower wire rack, the workpiece is clamped on the workpiece clamping fixture, and the CNC system is programmed to energize the metal cutting wire, drive the workpiece to slide through the CNC system, and then cut the product.
