According to the analysis, among the tool materials selected by the domestic mold users, the most used ones are cemented carbide tools, accounting for 64.1%. With the development of super-hard tools, hard turning is gaining popularity as an economical alternative to grinding. The use of super-hard tool has been significantly improved, such as the cylinder bore machining in the semi-fine boring and finishing process in a lot of cubic boron nitride blades, the cutting speed reached a new height, the tool life is greatly extended. Indexable knives in China have been promoting for many years, progressing well, but the development is still not balanced, user coverage is still lower than the overall tool and welding tools. However, the technology of indexable knives in our country has made new progress in the promotion process, and the variety is rapidly increasing and has great potential for application.
Modern mold manufacturing machinery and tools used in the rapid development of technology, high-tech is widely used in the processing technology, cutting methods, tool structure, tool materials, tool coating, etc. have been with the traditional mechanical processing is large Different point. The new tooling and cutting inserts with new cutting edges and geometries are continuously researched and developed to meet the needs of CNC machine tools and high-speed machining tool holder and its connection with the machine tool such as HSK shank, thermoformed handle, hydraulic Knife handle, etc., and other new knife handle is widely used. In order to improve the production efficiency and reduce the tool changing time, more and more various composite tools are used in the processing of mold parts, such as complex boring and boring, complex drilling and reaming, complex drilling and threading compounding, etc. Of the expanding tool to meet a lot of special processing requirements, and some tools have even developed into mechanical, electrical and hydraulic integration of the device has gone far beyond the traditional concept of the tool.
Die tool industry consumption characteristics
In order to realize the mold lean production, the mold enterprise scientifically organizes the tool procurement and inventory management. It needs to research and explore how to reduce the capital occupation of the tool inventory in order to ensure the normal operation of the production line, to optimize the minimum stock setting of the tool and to purchase the starting point of the tool , Reasonable purchasing frequency of tool and purchasing batch, establishing effective tool early warning mechanism, emergency mechanism and rapid response mechanism, with scientific and effective method tracking, monitoring tool inventory status and purchasing status. It is understood that 68.5% of the user's business tool costs accounted for the proportion of the total cost of less than 3%, and the cost of manufacturing tools in developed countries account for about 4% of the cost of production, there is a big gap, which is causing China's manufacturing cutting low A factor.
China mold industry decentralized, low-scale, low-level phenomenon, the Chinese mold manufacturer is a very large number of very few, most of the remaining small and medium-sized. These conditions determine the mold industry users use the tool features: more purchases, the procurement frequency, that is, up to two months or so once purchased, on the one hand reflects the more mature consumer market, the tool industry in the mold industry, users tend to set budgets Flexibility, not to keep too much inventory. At the same time, due to the flexibility of user purchasing, the market offers ready access to tool suppliers that have not yet entered. Due to the on-demand purchasing, the mutual replacement of used brands is also increasingly competitive.
Affect the purchasing power of the knife factors
Users pay more attention to efficiency, input-output optimization, rather than pay attention to purely price factors. The connotation of "service" has been developed from the simple pre-sale service to the solution of the cutting plan.
Tool performance and quality directly affect the smooth processing of the required qualified products, the tool can meet the requirements of high-speed cutting, tool life and how the frequency of tool change have a direct impact on the production line start-up rate, affecting the processing beats and production efficiency, The timely and quality assurance will be adjusted or repaired a good tool to the production line in turn will be directly related to the normal production can continue. Therefore, Luo Baihui believes that the tool industry, tool industry users consider the main tool: cutting efficiency is the most important, followed by life, service is more emphasis on this factor, tool manufacturers also introduced a variety of measures, and purchase companies to complete the production.
