The rapid development of the manufacturing industry not only drove the prosperity of the domestic mold industry, but also raised higher and higher requirements for domestic mold manufacturers: the delivery period was further shortened, and the supply of high-end mold products was in short supply. Faced with huge market demand and fierce market competition, mold manufacturers are faced with the dual pressure to improve the grade of mold products and reduce manufacturing costs, and this pressure will certainly be transmitted to the upper and lower ends of the supply chain, so the corresponding tools (tools) The industry has also put forward new requirements. In recent years, the product level of China's tool companies has been increasing year by year, and the competition among tool companies has become increasingly fierce. Looking at the whole country, large and small, well-known domestic and foreign tool factories (tool agents) abound, Sandvik , Val special, Iscar, Leitz, KORIOY, Dai Jie, Hitachi, Mitsubishi, Kenner, strains of drilling, Xiamen Golden Egret ...... to compete, the major tool manufacturers are racking their brains to continuously from product price And technical service solutions to enhance core competitiveness. In the face of the dazzling tool market, how should the mold factory choose? To this end, we conducted a simple scan of the major tool manufacturers in China, and conducted a horizontal comparison from the aspects of products, technology and services, hoping for your purchase. for reference. Compared with machine tools, small tools account for only 3% to 5% of the total manufacturing cost, but their role can not be ignored. The machine tool can provide a good motion and control platform for mold production, but the tool that directly completes the cutting process and is in direct contact with the workpiece is the tool. The shape, size, precision and surface topography of the workpiece are all realized by the action of the tool. . Whether the operation of the machine tool is sufficient and whether the cutting of the workpiece is reasonable is closely related to the selection of the tool, the performance, the quality difference, and the process. The tool can complete the roughing, semi-roughing, finishing, margin milling and primary (or secondary) cleaning of the mold, and the roughest blank is processed into finished products that meet various needs. The use of advanced and efficient tools can also help mold manufacturers reduce processing costs and increase production efficiency. The fierce competition in the market for toolmakers ' survival manuals will inevitably bring more pressure on tool manufacturers, but from the perspective of the development of the entire tool industry and the perspective of tool users, competition is beneficial, and competition will be even greater. improvement. The most intuitive result of competition is the decline in product prices and the improvement of service quality to meet the needs of the market and customers, as well as the tool industry. For tool manufacturers, on the one hand, we must continuously improve the cost performance of the tool to meet the needs of mold companies, on the other hand, we must reduce our own manufacturing costs and improve service quality to participate in fierce market competition. In the face of double challenges, tool makers, where to go? Rapid response technology solutions One of the most important ways for mold manufacturers to reduce costs is to improve cutting efficiency and reduce unit costs in manufacturing. This can be achieved not only by increasing the cutting speed but also by increasing the amount of cutting; it can also be achieved by reducing the auxiliary time, such as the tool change time, and by minimizing the chance of failure in certain processes. This puts higher demands on the tool supplier's technical solution capability. It is necessary to be able to analyze and discover the causes and influencing factors of the cutting process problems occurring in the tool-related production process, and to make timely and relevant problems of the tool. Respond, quickly identify problems and propose solutions and suggestions for solving problems. If necessary, you should quickly reach the problem site, strictly control the various elements of the tool itself, and make appropriate and timely improvements and optimizations to provide perfect and timely sales. And after sales service. Japan Daijie not only set up distribution points in major cities in China, but also set up offices in Shanghai and appointed senior technicians to provide pre-sales services and after-sales technical support and services. System engineering's overall planning ability The actual production experience shows that the problem of tool cutting and machining is a complicated system engineering. In the mold processing, the input of the system is the production requirement, and the output of the system is the processing result obtained through the processing. There are many factors and variables in the system, such as machine tools, fixtures, tools, cutting fluids, workpiece materials, blanks, etc., in which the tool itself is a subsystem with many variables, the structure of the tool, the geometry of the cutting edge, the tool Materials, surface coatings, etc., all of these variables intersect and interact with each other. For example, an unreasonable concentration or an inappropriate type of cutting fluid not only causes the tool life to become shorter, but also causes abnormalities in the workpiece being machined; An unreasonable machine tool can not only make the tool perform its function, but also cause chipping and breakage of the tool. The development of new technology comes from the actual production practice. Walter has established a long-term technical exchange and cooperation relationship with the customer Makino Machine Tool to continuously adjust the harmonicity of the tool and the machine tool to maximize the processing efficiency of the machine tool. Therefore, for tool manufacturers, on the one hand, continuous efforts in tool technology have reached the level required by mold manufacturers, on the other hand, it is necessary to strengthen cooperation with machine tool manufacturers, fixture manufacturers, cutting fluid manufacturers, materials factories, etc. When an abnormal situation occurs in the process, it is necessary to analyze and solve the problem from the perspective of system engineering. Instead of simply seeing the tool problem in the system, it is necessary to consider the problem from a system perspective, analyze the relevant important factors, and improve The ability to coordinate the system engineering in the cutting process. Innovative technological capabilities In this environment where society advocates innovation, knives are no exception. From the exhibitions in recent years, we can find that innovation has been valued by many companies, especially some well-known foreign machine tool companies. Many companies have developed more advanced tools, such as unfolding tools, and the blade is just a complete set of tools. In one component, the whole set of tools also includes transmission and control mechanisms, etc. The production efficiency of such tools is very high; combined tools (composite tools) and a composite knife can solve the processing of multiple processes in the original multiple stations. Moreover, the auxiliary time of multiple tool changes is reduced, which is beneficial to improve machining accuracy and processing efficiency; and so on, and therefore is more trusted and supported by customers. For example, the rigidity of a tool is inversely proportional to the amount of overhang of the tool. When using a ball end mill for copy milling, the tool must have a large amount of overhang. Therefore, in order to improve the rigidity of the tool when designing the end mill Usually, a tapered neck is added between the blade and the shank, but when the straight wall is high, this method is not feasible. In order to solve the high-efficiency and high-precision machining of the straight wall in the mold processing, the Japanese OSG development FXS? MFE end mills, in the straight wall processing, step-by-step machining, to achieve high-speed machining. As far as domestic tool companies are concerned, many companies have developed very rapidly, such as Zhuzhou Diamond and Xiamen Golden Heron. However, from the perspective of the development of the whole industry, domestic enterprises are still inferior to foreign companies in terms of technological innovation. Cost-effective product range In order to further improve the tool range, Seco has successfully acquired the French tool holder and file manufacturing company EPB and the Dutch company Jabro which manufactures solid carbide milling cutters . The fierce market competition, the reduction of manufacturing costs and the multiple pressures to increase production efficiency have made mold manufacturers have to choose cost-effective tool products, which is also the real status quo of tool companies participating in market competition. Roughing tools not only need to work quickly and efficiently, but also can withstand high temperatures, high pressures and wear resistance; finishing tools can improve the size, shape and surface roughness of the mold, reducing or even eliminating manual grinding, thus greatly reducing The manufacturing cost of the mold manufacturing company and the shortening of the manufacturing cycle of the mold, and delivery in advance. The geometrical parameters of the tool provided by the tool manufacturer to the customer should be as much as possible and detailed, such as the type, diameter, blade length, overhang and related parameters of the machine tool, and can provide the tool products and requirements according to the customer's requirements. The debugging work is to enable the mold company to put the tools into production as soon as possible and improve production efficiency.
