environment and safety precautions of edm drilling machine According to the speed of the electrode wire movement can be divided into high-speed wire walking and low-speed wire walking, the electrode wire movement speed of 7 ~ 10m/s is high-speed wire walking, less than 0.2m/s is low-speed wire walking, Most of the existing domestic wireline cutting machine tools are the former, foreign products and domestic wireline cutting machine tools developed in recent years are mostly the latter, and in China, the preparation of machine tool models is carried out according to the provisions of JB 1899-76 "Metal cutting machine tool model preparation method", the machine tool model is composed of Chinese Pinyin letters and Arabic numerals. It represents the categories, characteristics and basic parameters of the machine tool.

As an advanced processing method in machinery manufacturing, environment and safety precautions of edm drilling machine has the following advantages:

1, using the principle of electrical corrosion processing, the electrode wire and the workpiece are not in direct contact, the force between the two is very small, so the deformation of the workpiece is very small, the electrode wire, the fixture does not need too high strength.

2, environment and safety precautions of edm drilling machine directly use linear electrode wire as electrode, no need to make electrical grade, can save electrode design and manufacturing costs.

3, environment and safety precautions of edm drilling machine can process the complex shape of the workpiece that is difficult to process or can not be processed by traditional cutting methods. Because the CNC EDM machine tool is a digital control system, so the processing of different workpieces only need to prepare different control programs, and it is easy to realize automatic processing of different shapes of workpieces. It is suitable for the processing of small batch of complex shaped parts, single pieces and trial products, and the processing cycle is short.

4, environment and safety precautions of edm drilling machine adopts four-axis linkage, can process taper, upper, lower allotrope and other parts.

5, the traditional turning, milling, drilling processing, tool hardness must be greater than the hardness of the workpiece, and the electrode wire of the CNC EDM cutting machine need not be harder than the workpiece material, can be processed with high hardness or very brittle, with the general cutting method is difficult to process or can not be processed materials. The electrode wire used as a tool in processing does not need sharpening, which can save auxiliary time and tool costs.

6, the direct use of electricity, heat for processing, it can be convenient to affect the processing accuracy of the processing parameters (such as pulse width, interval, current) to adjust, is conducive to the improvement of processing accuracy, easy to achieve automatic control of the processing process.

7, the working liquid using water machine emulsion, low cost, no fire.

8, EDM cutting can not process non-conductive materials.

9, compared with the general cutting processing, the metal removal rate of edm drilling machine wire cutting processing is low, so the processing cost is high, not suitable for the mass parts processing with simple shapes.
