Whether it is stable and reliable in the supply of the required components of the equipment, high quality; c. Whether it has reached a certain scale in the production batch; d. Whether there are certain users in the sales; e. Is there a special technical support? Personnel and spare parts library; f. In management, it is qualified for ISO9000 series certification. Model equipment that is discontinued due to immature technology or poor management (single child or prototype); b. Manufacturers who are unable to engage in technical services or technical support due to lack of technical strength or insufficient funds; c. relying on advance payments and difficult business operations Manufacturers who wait for the rice to cook; d. Manufacturers who face restructuring and bankruptcy due to poor business management; e. Manufacturers facing economic crisis, political unrest, and war-torn areas. Therefore, it is required that the selection personnel should have a strategic vision, and they cannot be accommodated on this issue, nor can they have any compassion. Otherwise, it will bring endless hidden dangers to future management and use, and at the same time, it will cause huge waste to the state's investment. The key to the selection of CNC machine tools The type, specification and accuracy of CNC machine tools The selection of CNC machine tools must first be comprehensively analyzed from the part type, size, batch size and processing complexity of the product to determine the type and specifications of the machine tool. Precision. On the one hand, considering the advanced nature and adaptability of CNC machine tools, it can still adapt to the requirements of products when the product is improved; on the other hand, it should try to avoid selecting CNC machine tools with too large specifications and high precision, because the specifications are too large and accurate. The requirements are too high and the price is expensive. Therefore, the selection should be analyzed and compared from the aspects of type, specification and precision. Type Selection The type of machine tool to be selected depends on the design structure of the workpiece and the material of the workpiece. Each type of machine tool has its own processing object. Such as CNC lathes, CNC milling machines, CNC grinding machines, vertical machining centers, horizontal machining centers, vertical and horizontal conversion machining centers, CNC tool sharpening machine tools, CNC wire cutting machine tools, etc. have their own processing objects. Therefore, the company should determine the type of CNC machine tool to be selected based on the structural type of the workpiece. Reasonable choice of CNC machine tool options The function of the CNC machine tool consists of two major parts: the basic function and the option function. The basic function is the inherent function of the system, the price is included in the total price of the machine; the option function is a setting function for the user to select for special processing or specific needs, such as macro B or variable programming function, spline Interpolation function, man-machine dialogue programming function, graphic display simulation function, ladder display diagnostic function, tool life management function, probe detection function, etc., the price is not included in the total price, and must be separately priced. The more these features, the better the performance and the more expensive they are. Therefore, the function strength of CNC machine tools is closely related to price, and there is a trade-off between function and price. To this end, in the actual selection, we must not blindly pursue advanced, we must take all factors into consideration, and fully consider the economic and investment effects. CNC machine tools should be matched, CNC control system should be as uniform as possible CNC machine tool CNC system, there are Japan FANUC, MITSUBISHI system, Germany's HEI-DENHAIN and MILLPLUS, SIEMENS system, Italy's FAGOR, FIDIA system, France's NUM system, the United States AB's system, VINCERSA2000 of CINCINNATI, 88HS of FADAL, CEN-TURION6 system of MILLTRONICS, etc., China's "Huazhong I", "Aerospace Type I", "Chinese I", etc. These systems have their own different systems. The series has a very different function and the price difference is also large (such as the control function of the number of control axes and the number of linked axes). Therefore, when selecting the numerical control system of the machine tool, it should firstly start with the numerical control system that the enterprise has mastered or is currently using, combined with the current actual conditions of process, programming, operation, maintenance, management, etc., as far as possible to make the CNC machine tool supporting, CNC control The system is unified. At the same time, combined with the latest modern CNC technology, the CNC system is appropriately expanded and updated in a layered manner, so that it can be stably and continuously developed in the future. Equipped with the necessary accessories and tools in order to effectively play the role of CNC machine tools and enhance their processing capabilities, the necessary tool accessories and tools must be equipped in the selection. Such as tool presetter or tool setting instrument, measuring head and measuring device, automatic or manual aligner, automatic programmer and corresponding software, additional workbench, tool system, etc., these accessories and tools in the CNC machine manual or related materials It is described in detail in the selection. In the selection, it should be considered according to the characteristics and actual conditions of the processed products of the enterprise to meet the processing requirements. In particular, the choice of the tool should pay attention to the specifications of the spindle, the size and shape of the holder and the size of the handle or the size of the handle. Adhere to the principle of high reliability and proper quantity, avoiding the quality problems or lack of accessories and tools, affecting the operation of the whole machine; avoiding idleness due to repeated purchase of accessories and tools, resulting in waste. Priority is given to domestically produced high-quality CNC machine tools. When selecting CNC machine tools, domestic high-quality CNC machine tools can meet the requirements of use, and domestic equipment should be preferred. On the one hand, it is to stimulate domestic demand, promote domestic economic growth, develop national industries, support the development of domestic machine tool manufacturing, and shorten the gap with the international machine tool manufacturing industry. On the other hand, in order to obtain convenience in technical training, after-sales service, accessory support, parts supply, etc., at the same time, in order to obtain cheap prices, reduce investment in technological transformation of enterprises. Therefore, it is necessary for the user to support the development of the national industry and promote the products of the Chinese machine tool manufacturing industry into the world. The selection of CNC machine tools, especially the machining center, is a comprehensive and highly specialized technical project. It requires a group of management personnel and engineering technicians with professional knowledge to explore and improve in practice. For the production and development of products, how to effectively select equipment for the processing of workpieces for military production is a systematic project for technological transformation of enterprises in the future. It is hoped that the selected personnel can assume the mission and responsibility assigned by the enterprise, so that the selected CNC machine tools can fully display their functions, effectively complete the production and processing of the products, and bring a rich return to the investment of the enterprise.
