What is cnc wire cutting

Wire cutting, from a professional point of view, generally refers to wire cutting machine tools, he is a metal processing machine tools. Different from ordinary metal cutting machine tools, ordinary machine tools will basically produce cutting force, wire cutting is a machine tool without cutting force, belonging to the electric discharge machining machine tool.

Wire cutting works by passing a wire with a thin metal wire through the workpiece, and then controlling the current and electricity so that the current generates intermittent electrical spark discharge between the workpiece and the wire. These sparks will instantly generate high temperatures on the surface of the workpiece, thereby causing partial loss, melting and evaporation of the metal workpiece. With the continuous occurrence and movement of electric sparks, the metal workpiece is gradually cut into the desired shape.

Wire-cutting has a general CNC programming and processing system, and the machine tool can automatically cut according to the program. However, the workpiece to be machined must be metal and an electrical conductor. However, in recent years, with the maturity of technology, sampling and tracking research, such as polysilicon and monocrystalline silicon semiconductors can also be cut.

Wire-cut has the following advantages:

Can cut high hardness and good thermal conductivity materials, such as steel, titanium and so on.
Can cut complex shapes and small sizes of the workpiece.
There is no cutting strength, so there is no significant thermal deformation on the surface of the workpiece.
Small cut marks can be created on the surface of the material.
Wire cutting is widely used in the manufacturing industry, especially for mold manufacturing, aerospace and automotive industries. It can achieve high precision cutting and can handle hard materials, so it is an important processing method in many fields
