Electrical discharge cutting
Electrical discharge metal cutting is the machining of parts with a wire-cutting machine through action of electrical impulses arising between the electrodes (the material and the tool).
A DC power source is connected to the workpiece and the electrode. It generates short-term pulses passing through the electrodes. Thus, an electron arc is formed in the active zone. This arc acts as a cutting tool.
Wire cutting of metal is performed on a special high-power machine. The plasma arc enables cutting a metal workpiece into any number of elements. The cutting depth can be adjusted to the values you need, if necessary. We should note that the standard depth is 20 - 40 diameters. The average cutting rate is 0.1 — 0.5 mm per second.
This technology is characterized by reliability and allows for high-precision metal machining. It is suitable for cutting any metals, as well as their alloys. For example, steel, cast iron, brass, aluminum, etc.
Electrical discharge cutting is in demand in high-precision industries.
It should be noted that since ED equipment is quite expensive, the price of electrical discharge metal cutting is also rather high. However, this is the best option for metal cutting if you need maximum precision.
