What is CNC Die Sinker EDM Machine?

CNC die sinker EDM machine refers to a machine that can realize the discharge machining or the multi-axis dynamic discharge machining. The mechanical structure of the sinker EDM machine is firm and strong with a practical function. Sinker EDM machine is perfect machining applied in the tooling industry for it can produce molds with high precision and smoothness. EDM die sinking machine is wildly used in any industry which requires a precision finish. Due to the hard property of metal, the spark erosion machine only comes out with the electrical sparks rather than touches the metal directly.



Die Sinking EDM Operation

Die sinking EDM is carried out in a liquid medium. The automatic device of the EMD die sinking machine keeps a proper discharge gap between the workpiece and the tool electrode. When a strong pulse voltage is applied, the dielectric insulation strength is at the lowest point. Because the discharge area of the CNC EDM spark machine is very small and the discharge time is very short, the energy is highly concentrated, so that the temperature is as high as 10000-12000 ℃. Then the metal is thrown into the working fluid. And the shape of the sinker EDM machine electrode is reproduced on the workpiece.

Ram Type CNC EDM Machine with Fixed Table

Ram Type CNC EDM Machine with Fixed Table

This type of EDM machines are usually big for heavy loading, therefore, we call them large CNC EDM machines, the structure has a fixed working table, the motion of X, Y, and Z-axis are all located on the saddle side. Because the weight of the workpiece is not giving gravity on moving axes, so when the workpiece comes very heavy, there is no influence of moving parts, the ideal of heavy molds machining.

ZNC Die Sinking EDM Machine

ZNC Die Sinking EDM Machine

ZNC electrical discharge machining machine is the traditional type with X and Y-axis manual control, usually, the operator needs to manually move the working table to the location of where to do spark eroding on the workpiece. Z-axis is automatically controlled by servo motor, operation of ZNC EDM spark erosion machine is simple compared to CNC die-sinking EDM. Due to the limitation of no control of the X and Y axis, the ZNC EDM spark erosion machine can't do simultaneous orbital machining, even use an orbital cutting head, the result of accuracy and surface is not as good as what can achieve on CNC EDM machines. But thinking about the cost of ZNC EDM, it's ideal for the start or jobs without a strict requirement of accuracy and surface finish. Contact us to get our ZNC EDM spark erosion machine price now!

The Mostly Asked Questions about Die Sinker EDM Machines

What's EDM die sinking machining (EDM forming machining)?

The EDM die sinker machine is able to cope machining by prepared electrodes, the cavity that created is the same as the profile of the electrode. EDM machine can process punches, drawing dies, and extension dies of various types of holes; process various forging dies, extrusion dies, plastic injection molds and extrusion dies; and also process various small holes, deep holes, heterosexual holes, and curved holes,  and special materials with complex-shaped parts, etc.

What is the EDM machine meaning in the metal working industry

Electrical spark erosion, also known as electrical discharge machining and electrical corrosion machining, called electrical discharge machining in Japan and electrical corrosion machining in the former Soviet Union. It is a method of processing the metal workpiece by utilizing the phenomenon of electric corrosion generated during the pulse discharge between the two poles (electrode and workpiece, should be conductive). Academically it belongs to the category of electrophysical processing. EDM technology is one of the most important parts of special machining technology.

What is the advantage of electrical discharging machining against traditional metal working method?

Answer: With the development of industrial production and the advancement of science and technology, more and more new materials with a high melting point, high hardness, high strength, high brittleness, high viscosity, high toughness, high purity and other properties continue to appear, and also some with various complex structures that can’t be machined by traditional metal working method, sometimes difficult or impossible to process with traditional metal working technology. 


Therefore, in addition to further development and improvement of traditional mechanical metal working methods, wire EDM machine suppliers also strive to find new processing methods. The electrical discharging machining (EDM) method can meet the needs of development, and shows many excellent performances in the application, so it has been rapidly developed and increasingly widely used. 


Characteristics of EDM die sinking machining

(1). During machining, the tool electrode and the workpiece material are not actually touching and there is basically no macro-mechanical force between the two. Therefore, the "soft" tool electrode can be used to process the "hard" workpiece. For example, graphite and copper electrodes can process hardened steel, cemented carbide, and even diamond.

(2). Because the spark energy density of the high-frequency power discharging can be accurately controlled, and there is no macro mechanical force between the two poles (electrode and workpiece), so the precise and fine machining can be achieved. Such as the processing of narrow slits, narrow grooves, micro-small holes of molds and parts, the processing accuracy can reach micron level, even sub-micron level.

(3) "Copying". With direct use of electrical power for processing, it is easy to realize the automation, intelligence, and application of modern computer control technology to precisely control the machining process, which makes the machining of workpieces more realistic.

(4) Direct use of electrical energy for processing, which is convenient for automation of the machining process, and can reduce mechanical processing procedures, shorten processing steps, low labor intensity, and easy to use and maintain
