Product Description
Using a continuously moving thin metal wire (called electrode wire) as an electrode, the workpiece is subjected to pulse spark discharge to remove metal and cut into shape. The electrode wire is usually made of molybdenum wire, tungsten wire or copper wire. During the processing, a certain discharge gap is maintained between the electrode wire and the workpiece, and a high-frequency pulse voltage is applied to the electrode wire and the workpiece through a pulse power supply, so that the working fluid (usually deionized water or emulsion) between the electrode wire and the workpiece is broken down, forming a discharge channel, generating high temperature and high pressure, causing the workpiece material to melt and vaporize instantly, thereby realizing the cutting process of the workpiece.

application
Mold manufacturing: widely used in the manufacture of various molds, such as stamping molds, plastic molds, die-casting molds, etc. It can process high-precision mold cavities and cores to ensure the dimensional accuracy and surface quality of the mold and improve the service life of the mold.
Precision parts processing: used to process various precision parts, such as aerospace parts, electronic components, automotive parts, etc. It can meet the strict requirements of these parts for accuracy and surface quality and realize the processing of complex shapes.
EDM: As a special form of EDM, it can also be used for the manufacture of electrodes for EDM forming processing, as well as EDM perforation, cutting and other processing of some parts that are difficult to machine.
Features:
High processing accuracy: The accuracy of wire cutting can usually reach ±0.01mm or even higher, which can meet the processing requirements of various precision parts.
Complex shapes can be processed: The motion trajectory of the workbench can be controlled by programming to process various complex two-dimensional and three-dimensional workpieces, such as mold cavities, contours of precision parts, etc.
Strong material adaptability: It can process various conductive materials, including hard alloys, hardened steel, stainless steel and other difficult-to-process materials.
Small processing allowance: Wire cutting is a non-contact processing. There is no mechanical cutting force between the electrode wire and the workpiece, so the processing allowance can be very small, which is conducive to saving materials and improving processing efficiency.
High degree of automation: Most modern wire cutting machine tools use CNC systems, which can realize functions such as automatic programming, automatic processing, and automatic detection, reducing manual intervention and improving processing efficiency and stability of processing quality.
