DIE SINKER EDM MACHINE FAQS

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 spark erosion machining 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.

Uses of EDM machining technology

(1) Processing various technologies and their alloy materials, conductive super-hard materials (such as polycrystalline diamond, cubic boron nitride, cermets, etc.), special heat-sensitive materials, semiconductor, and non-semiconductor materials.

(2) Processing various kinds of complex-shaped hole and cavity workpieces, including processing round hole, square hole, polygon hole, special-shaped hole, curved hole, threaded hole, micro hole, deep hole and other type hole workpieces, as well as various types Face cavity workpiece. For example, processing exceptionally large molds and parts ranging from a few micrometers of holes and grooves to several meters.

(3) Cutting of various workpieces and materials, including cutting of materials, cutting of parts with special structure, cutting of fine narrow slits and parts composed of fine narrow slits (such as metal grid, slow wave structure, heterogeneous orifice spinneret, laser Pieces, etc.).

(4) Processing all kinds of forming parts such as forming knives, samples, tools, measuring tools, threads and so on.

(5) Grinding of workpieces, including small holes, deep holes, inner circles, outer circles, flat surfaces, etc. and profile grinding.

(6) Engrave and print nameplates and marks.

(7) Surface strengthening and modification, such as high-speed quenching of metal surfaces, nitriding, carburizing, coating of special materials and alloying, etc.

(8) Auxiliary uses, such as removing taps and drill bits from parts in this segment, repairing worn 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, people 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
