The most popular rapid development of China's mold

The rapid development of China's mold industry affects the purchasing power of cutting tools. In recent years, with the development of mold manufacturing industry, the requirements for mold parts and materials have increased. Superhard tool materials such as CBN (cubic boron nitride), PCD (polycrystalline diamond) tools and new cemented carbide tools have been widely used. The consumption and purchase of cutting tools have become a common topic of concern for mold manufacturers and tool manufacturers

one body also shows the application of zigzag cutting tools before and after aging because it can not completely eliminate the internal stress of aluminum alloy profiles.

according to the investigation of luobaihui, Secretary General of the International Mold Association, among the cutting tool materials selected by domestic mold users, cemented carbide cutting tools are the most used, accounting for 64.1%. With the development of superhard cutting tools, hard turning is becoming more and more popular as an economical alternative to grinding. The utilization rate of superhard tools has been significantly improved. For example, cubic boron nitride blades are used in the most comprehensive results of semi precision boring and precision boring for the machining of cylinder bore of cylinder block. The cutting speed has reached a new height and the tool life has been greatly extended. Indexable cutting tools have been popularized in China for many years and are progressing smoothly, but the development is still uneven, and the user coverage is still lower than that of overall cutting tools and welding cutting tools. However, the technology of indexable cutting tools in China has made new progress in the process of popularization, and the varieties have increased rapidly, with great application potential

with the rapid development of machining and tool technology used in modern mold manufacturing industry, high and new technologies have been widely adopted, which are quite different from the traditional machining in the past in processing technology, cutting mode, tool structure, tool material, tool coating, etc. New tool structures and blades with new cutting edges and geometric shapes have been continuously studied and developed. Tool holders that meet the needs of NC machine tools and high-speed machining and their connections with machine tools, such as HSK tool holders, hot sleeve tool holders, hydraulic tool holders, and other new tool holders, have been widely used. In order to improve the production efficiency and reduce the tool change time, various composite tools are increasingly used in the processing of mold parts, such as drilling and boring composite, drilling and reaming composite, drilling and thread processing composite and other composite tools. The deployable tools with complex structure meet many special processing requirements. Some tools have even developed into mechanical, electrical and hydraulic integrated devices, far beyond the traditional concept of tools

characteristics of tool consumption in the mold industry

in order to realize the lean production of molds, mold enterprises should scientifically organize the purchase and inventory management of tools. It is necessary to study and explore how to reduce the occupation of tool inventory funds, optimize the minimum inventory setting of tools, the starting point of tool purchase, the reasonable purchase frequency and purchase batch, and establish an effective tool early warning mechanism Emergency mechanism and rapid response mechanism, with scientific and effective methods to track and monitor tool inventory status and purchase status. It is understood that 68.5% of the user enterprises' tool costs account for less than 3% of the total cost, which is far from the composition of the manufacturing cost in developed countries, which accounts for about 4%, which is also a factor causing the low cutting level of China's manufacturing industry

the dispersity, low scale and low level of China's mold industry is related to the phenomenon. China's mold manufacturers are very few with a large scale, and the rest are mostly small and medium-sized. These conditions determine multiple protection: it has the characteristics of software and hardware protection for users in the mold industry to use tools: the purchase volume is increased, and the purchase times are frequent, that is, purchase once every two months or so at most. On the one hand, it reflects that the consumer market is relatively mature, and tool users in the mold industry tend to be more flexible when making budgets, rather than keeping too much inventory. At the same time, due to the flexibility of user procurement, the market provides opportunities for those tool suppliers who have not yet entered the market at any time. Due to on-demand procurement, the competition for the replacement of used brands is also increasing

factors affecting tool purchasing power

users pay more attention to efficiency improvement and input-output ratio optimization than simple price factors. The connotation of "service" has developed from simple pre-sales and after-sales service to cutting solution

the performance and quality of the tool directly affect whether the required qualified products can be successfully processed, whether the tool can meet the requirements of high-speed cutting, how long the tool life is and how often the tool is changed, which directly affect the starting rate of the production line, and the processing beat and production efficiency, Whether the adjusted or repaired tools can be provided to different combinations of force measuring and force adding methods to produce different styles of horizontal tensile testing machine lines on time and with guaranteed quality will directly affect whether the production can be carried out normally and continuously. Therefore, tool users in the mold industry mainly consider that cutting efficiency is the most important factor, followed by service life. The factor of service has been paid more attention. Tool manufacturers have also launched various measures to complete production together with tool purchasing enterprises
