In the period of planned economy, the grinding tool and grinding tool industry of mould parts processing in our country is the leading factory based on the seven grinding wheel plants belonging to the original first machinery industry department, and a grinding wheel manufacturing system is formed by the local grinding wheel plant belonging to the provinces, autonomous regions and municipalities directly under the central government. Now, after thirty years of reform and opening up the market test, resources integration, merger and reorganization, the original seven subordinate enterprises in addition to the original fourth grinding wheel factory on the basis of the Shandong Ruxin high-tech industry Limited by Share Ltd, some other enterprises are basically in a state of stagnation or difficult business. The first grinding wheel factory in Shenyang has already been bankrupt; the second grinding wheel factory in Zhengzhou is the first listed company in the industry. The company is called the "white pigeon Limited by Share Ltd", referred to as "the white pigeon". It has now been decomposed into several small enterprises by the backdoor, and is faced with difficulties; the third grinding wheel factory in Guizhou and the sixth grinding wheel factory are merged into the market. After seventh grinding wheel factory, it failed to fundamentally solve the problem of its development. Several sub division and cooperation, big injury, seven sand group are also faced with bankruptcy. Its production and operation part has also been decomposed into several small enterprises, which are difficult to operate with the advantages of resources (mainly electricity price and raw materials); and the fifth grinding wheel factory in Xian is mainly produced. The manufacture of silicon carbide rods is basically not in the category of abrasives industry. After the reform and opening up of the interior and exterior diameter grinding in Dongguan, a large number of private mould and mould parts processing Abrasives manufacturing enterprises have emerged in China. Although there are no lack of fine enterprises which promote the development of industry and technological progress, a large number of private enterprises rely solely on their flexible management system and rely on the "excavation of the original state-owned leading factories." The technical workers of our country are still at a lower level in the whole of the abrasive and abrasive industry in general, and the technical content and added value of the products are relatively low. Source and artificial advantages provide cheap raw materials for foreign advanced Abrasives manufacturing enterprises. Now, only Ruxin high and new rely on great efforts to improve the ability of independent innovation, after six years of effort, finally out of the dilemma, at the same time have a greater potential for development. - in recent years, the use of 3D CAD in Dongguan has been more and more, and some enterprises have achieved full application. At the same time, CAE technology is also widely used. On the one hand, it is the CAE software introduced from abroad. After two development, the application level has been greatly improved; on the other hand, it has been developed at home, and the advanced CAE software with independent intellectual property rights has been successfully applied in production. At present, the CAE software that has been applied mainly includes the imported LS, DYNA3D, DYNAFORM, PAMSTAMP, OPTRIS, AUTOFORM and the domestic developed VFORM, KMAS, sheetForm and CADEM system. As the core technology CAE technology in the development of automobile large cover mould, the current CAE software has been upgraded in the traditional forming analysis, and can participate in the whole process of stamping process. There are significant progress in the analysis of the universality, practicality and precision of the content. This will play a significant role in product design and process analysis, improving the success rate of dies, especially the drawing dies, shortening the manufacturing cycle and improving the quality of dies. Advanced technologies such as digital manufacturing, reverse engineering, concurrent engineering, sensitive manufacturing and lean production have also been applied in automobile panel die production, and have produced good results. Although CAPP is widely used in mould factories, there are many successful examples. High speed machining technology, which has seldom been used before, is now being used more and more. The software of the intelligent and automated, all directional (from data to product) mold parts processing die design and processing solutions, which integrates a large number of experience, standards and specifications in the mold design and the CAD/CAM technology system, has also been applied, which has effectively raised the quality of the mold and shortened the production cycle of the mold. . Due to the improvement of the equipment level, the improvement of the design and processing technology, the improvement of the personnel quality and the application of some new technologies, in recent years, the level of the domestic automobile panel die has also been greatly improved. Luo Baihui, Secretary of the International Mold Association, believes that the improvement of mold level is manifold, and is reflected in the whole process of mold production. The moulds that were not produced in the past can now be produced
