Because of Chinas Graphite deep processing products started late, compared with developed countries, the deep processing technology of graphite products in China, these so-called graphite products can only be regarded as graphite semi-finished products, so it is compared with the world Chinas Graphite deep processing products are far from developed countries was thrown open by a large margin. In this big data, special transformation of science and technology in particular, explore the road of graphite products processing, is to reverse the situation of Chinas Graphite low high into the important weight. Gold era, explore the deep processing of graphite products long and steep, "explore" two word itself there are all kinds of hardships and thorns, insist on, we can go further to think.
In recent years, China has made great progress in graphite deep processing. Due to the improvement of graphite purification and suppression methods, the characteristics of graphite to play more vividly, such as our common isostatic graphite, EDM graphite, molded graphite, as well as special graphite, etc.. According to the understanding of the graphite products processing for many years, according to the different uses of graphite products, graphite materials with different physicochemical indexes, take with the solar photovoltaic industry industrial silicon industry, graphite product quality determines the quality of monocrystalline silicon, the thermal field of single crystal furnace, the core part is the graphite crucible and graphite graphite heater, heat shield, graphite, heat insulation barrel, inside and outside the draft tube and others connected components in graphite, graphite raw material selection must be reasonable.
We all know the good-for-nothing, similarly graphite processing is not useful, because the graphite has good conductivity, lubricity, corrosion resistance, thermal shock resistance There is nothing comparable to this other metal materials such as the role of the graphite products known as conductive materials; used as a refractory material; as the corrosion resistant materials; wear resistance and can be used as as high temperature lubricating materials; metallurgy and high purity materials for structural materials; as the mold, using the die; in the atomic energy industry and military industry, the application of graphite graphite from handicraft to aerospace and other fields, we can see the figure of graphite products. Graphite products from the industry in our country is not difficult to see the application of graphite products tentacles have penetrated into various industries.
Characteristics and application of special tools for graphite processing
Compared with the copper electrode, graphite electrode has the advantages of electrode consumption, fast processing speed, good machining performance, graphite processing of high precision, small thermal deformation, light weight, high temperature resistance, easy processing, surface processing of high temperature, electrode bonding etc.. Although graphite is a very easy cutting material, but because the graphite electrode materials used for EDM must have enough strength, so as to avoid damage in operation and EDM processing, and the electrode shape (thin, rounded, sharp change etc.) also put forward higher requirements on the graphite electrode of grain size and strength. This resulted in the process of graphite graphite workpiece easily broken, the tool is easy to wear.
Tool wear is one of the most important problems in graphite electrode machining. Wear not only affects the cost of cutting tools, processing time and processing quality, but also affects the surface quality of the workpiece machined by the electrode EDM. The main tool wear regions of graphite electrode materials are the front and back surfaces. On the rake face, the impact contact between the tool and the broken chip area results in impact abrasive wear.
