EDM Die Sinking Machine: Key technical equipment for precision machining

In modern manufacturing, precision machining technology is essential for the production of complex parts and high-quality mold manufacturing. As an efficient precision machining equipment, EDM Die Sinking Machine has become one of the core equipment in mold manufacturing and aviation, automobile and other industries by virtue of its outstanding performance in hard material processing, complex shape mold forming and other fields.
EDM Die Sinking Machine is a machine tool equipment that uses the principle of electric spark discharge for processing. It melts and vaporizes the material through the high-temperature electric spark formed between the workpiece and the electrode, thereby accurately removing the material. This equipment is usually used to process high-hardness, difficult-to-cut materials and complex three-dimensional curved surface shapes, and is a tool for precision mold manufacturing.
Provide the electrical energy required for electric spark machining and control the discharge frequency and intensity.
Designed according to the shape of the mold or workpiece, it is used to discharge between the workpiece.

Use dielectric fluid (such as spark oil) to control the cooling, insulation and chip removal of the processing area.
Achieve precise processing paths and automated operations through CNC technology.
The processing of EDM Die Sinking Machine is based on the phenomenon of electric spark discharge. When a tiny gap is formed between the workpiece and the electrode, after the pulse voltage is applied, the electric field strength exceeds the breakdown strength of the dielectric fluid, thus forming a high-temperature discharge. At this time:
The electrode and the workpiece surface are partially melted and vaporized to form tiny pits.
The processing area is cooled by the dielectric fluid, and the generated processing debris is quickly washed away.
This process is repeated at a very high frequency, gradually forming the required complex shape.
Main Features of EDM Die Sinking Machine
EDM Die Sinking Machine can easily process materials with high hardness and strong toughness, such as hardened steel, titanium alloy, tungsten carbide, etc., which are difficult to process with traditional cutting tools.
Since the electrode can be made into various shapes as needed, the equipment is particularly suitable for processing complex three-dimensional surfaces, deep cavities and fine structures, such as grooves and sharp corners of precision molds, injection molds.
There is no direct contact during the processing process, which avoids stress deformation and cracks on the workpiece surface caused by mechanical force, ensuring processing accuracy.
By adjusting the discharge parameters, EDM Die Sinking Machine can achieve micron-level processing accuracy and mirror-level surface finish to meet the needs of high-demand mold manufacturing.
Modern equipment is usually equipped with CNC control systems and automatic electrode changing devices, which realizes unattended processing and automatic programming of complex paths.
