The production of Shijiazhuang nipple electrode
Manufacturing of nipple electrode in Shijiazhuang The nipple electrode in mold manufacturing is mainly manufactured by milling. From the perspective of processing technology, graphite and copper are two different materials, and their different cutting characteristics should be mastered. If the process of processing copper nipple electrode is used to process nipple electrode, problems will inevitably occur, such as frequent breakage of thin slices, which requires the use of appropriate cutting tools and cutting parameters. The tool wear of processing nipple electrode is larger than that of copper nipple electrode. In terms of economy, it is the most economical to choose cemented carbide tools. Choosing diamond-coated tools (called graphite tools) is more expensive, but diamond-coated tools have a long service life. , The processing precision is high, and the overall economic benefit is good.
The size of the rake angle of the tool also affects its service life. A tool with a rake angle of 0° will have up to 50% longer service life than a tool with a rake angle of 15°. The cutting stability is also better, but the larger the bevel angle, the greater the processing time. The better the surface, the best processing surface can be achieved by using a 15° bevel tool. The cutting speed during processing can be adjusted according to the shape of the nipple electrode, usually 10 m/min, similar to processing aluminum or plastic, the tool can be directly up and down the workpiece during roughing, and the finishing is prone to chipping and chipping. Phenomenon, often use a light knife and quick walk. The nipple electrode generates a lot of dust during cutting. In order to prevent graphite particles from being sucked into the spindle and screw of the machine tool, there are currently two main solutions, one is to use a special graphite processing machine, and the other is to use an ordinary machining center Modification, equipped with a special vacuum device. Special graphite high-speed milling machine tools on the market have high milling efficiency and can easily complete the manufacture of complex nipple electrodes. The nipple electrodes have high precision and good surface quality.
If wire EDM is needed to make nipple electrode, it is recommended to use fine graphite material with smaller particle diameter. The performance of wire EDM of graphite materials is poor, and the smaller the particle diameter, the higher the cutting efficiency can be obtained, and the occurrence of abnormal problems such as frequent wire breakage and surface streaks can be avoided. When the carbon company was founded, it established the development strategy of “science and technology, innovation, and leadership”, adhering to the business philosophy of “quality first, service first”, through technological improvement, quality improvement, and market development, carbon has become a region in Shanxi, Hebei, and Mongolia. The largest graphitization processing company. The main business includes nipple electrode, Shijiazhuang nipple electrode, and Datong silicon carbide.
