China's cemented carbide tool to promote the development of mold industry development

In recent years, with the development of mold manufacturing, mold parts material requirements improve, superhard tool materials such as new carbide tool, CBN cubic boron nitride and PCD polycrystalline diamond tools are widely used, the tool consumption and purchase become the common concern of mold factory and tool production enterprises topic.

In the "Twelfth Five Year Plan" period of development will be hard alloy cutting tool industry is the trend of diversification. Die products will develop to large, sophisticated, complex and precision processing technology, intelligent control, computer technology and green manufacturing as one of the new technology of special process equipment; mold enterprises, technology integration, to create digital, information management, processing speed, excellent equipment and automation direction; business brand, the internationalization of the road; the industry is insist the informationization, green manufacturing and sustainable development.

Application integration tool

According to statistics, in the domestic mold tool material selected by the user, is the most frequently used carbide tool, accounted for 64.1%. While the development of super hard tools, hard turning is used as an alternative to grinding method better economy in the gradual popularization. Superhard tool utilization rate has been significantly improved, such as processing gas cylinder hole in semi fine boring and boring process of a lot of the cubic boron nitride blade, cutting speed has reached a new height, tool life is extended.

Indexable tool has been for many years, in the promotion of our country is progressing smoothly, but the development is not balanced, user coverage rate is still below the whole cutting and welding tool. However, our country of indexable tool technology has made new progress in the promotion process, varieties growing rapidly, the great potential.

Machining of the modern mold manufacturing and the use of cutting tool technology rapid development, high and new technology has been used in a large amount; in the process, cutting, tool structure, cutting tool material, cutting tool coating and other aspects have been the past traditional machining different points. The new tool and has a new cutting edge and the geometry of the blade is the constant research and development, adapt to the connection pieces such as HSK handle, handle, heat set hydraulic toolholder and other new tool widely used in NC machine tool and machining need tool clamping and machine tool.

In order to improve production efficiency and reduce tool change time, in the process of die parts are increasingly using a variety of composite tools, such as drilling and boring composite composite cutter, drilling and reaming compound, drilling and thread cutting composite and other types of, the complex structure of the expansion tool to meet a lot of special processing requirements, some even have developed into a tool device integration of machine, electricity, liquid, has been far beyond the traditional concept of tool.

Tool consumption characteristics of mold industry

In order to realize the mold of lean production, procurement and scientific organization tool mold enterprises and inventory management, need to study and explore how to ensure the normal operation of the production line of the lower cutter stock, optimizing tool set, minimum inventory tool purchase starting point, the cutting tool reasonable frequency of purchase and purchasing volume, build tool warning mechanism, effective emergency mechanism and rapid response mechanism, a scientific and effective method of tracking, monitoring tool inventory and purchasing status.

It is understood, the user enterprise tool costs accounted for 68.5% of the total cost is less than 3%, and the developed countries manufacturing tool costs accounted for about 4% of the production cost has a big gap, which is caused by a factor of our country's manufacturing cutting low level.

The Chinese mould industry dispersion, low scale, low level, China mould manufacturer is several scale big few, with most of the remainder is small and medium scale. These conditions determine the user tool characteristics of mold industry: more frequent purchase quantity, purchase, or at least two months buy time, it reflects the consumer market more mature, the mold industry tool users in the development of the budget is more inclined to flexibility, rather than to retain too much inventory. At the same time, because the user the flexibility of procurement, for those who have not yet entered the tool suppliers, markets provide ready access to opportunity. Due to the need to purchase, also increasingly competitive replace each other has brand.

Factors affecting the purchasing power of the tool

The user pays more attention to efficiency, input-output ratio optimization, rather than on the price factor simply. "Service" has the connotation of the pre-sale after sale service development to solve simple cutting scheme.

The quality and performance of the tool directly affects the smooth processing of qualified products required, the tool can meet the needs of high-speed cutting, tool life and tool changing frequency level have a direct impact on production line utilization rate, affect the machining time and production efficiency, and can according to time and quality assurance to adjust or repair tool grinding good for production line will be directly related to the normal production can continue to carry on.
