In the world of metalworking, there are technologies that go beyond the usual drilling and cutting. One of these is electrical erosion https://electroeroziya.ru / is a high—precision shaping method based on the effects of electrical discharges.
Operating principle and key features
The method is based on the controlled destruction of a conductive material under the action of an electric spark. The process takes place in a special liquid medium (dielectric) that insulates the workpiece and the tool electrode. When voltage is applied between them, a powerful discharge occurs, "burning out" a microscopic metal particle from the surface of the part. This process is repeated thousands of times per second, gradually forming the desired contour or cavity.
Standard milling operations https://electroeroziya.ru/tokarno-frezernye-raboty They differ from this process in that during electroerosion there is no direct mechanical contact of the tool with the part, which opens up unique production possibilities for creating the most complex products.
Key features of the technology:
- No direct contact between the tool and the workpiece.
- The treatment takes place in a dielectric liquid (oil, deionized water).
- The shape of the hole or cavity being created follows the shape of the instrument electrode.
- The material is removed not by cutting, but by the thermal action of a spark.
- The method is applicable to any conductive materials.
The main advantages of electroerosion
Due to its unique nature, electroerosion offers a number of significant advantages that make it indispensable in certain areas. It allows you to solve tasks that are impossible or extremely difficult to perform using traditional machining.
The main advantages of the method:
- Processing of superhard materials. Electroerosion is susceptible to hardened steels, titanium alloys, hard alloys, and other materials whose processing with a milling cutter or drill is ineffective or impossible.
- Versatility in complex tasks. This method is indispensable in the creation of molds, dies and unique components, including in the framework of tasks that reverse engineering solves. https://electroeroziya.ru/konstruktorskoe-byuro when it is required to recreate a complex detail with high precision.
- Creating complex geometric shapes. The technology makes it possible to produce parts with sharp internal corners, thin walls, deep and narrow grooves that are inaccessible to rotating tools.
- The highest accuracy. The method provides micron precision and excellent quality of the treated surface.
