In recent years, with the development of the oil pump manufacturing industry, the requirements of the oil pump component materials themselves improve, super hard tool materials such as CBN(cubic boron nitride), PCD(polycrystalline diamond) tools and new carbide tools are widely used, the consumption and purchase of tools become the topic of common concern of oil pump manufacturers and tool manufacturers. However, the technology of indexable cutting tool in our country has made new progress in the promotion process, and the variety is increasing rapidly and the application potential is great.
. It is understood that 68.5% of the user enterprise tool cost accounted for less than 3% of the total cost, and the manufacturing tool cost of developed countries accounted for about 4% of the production cost, there is a big gap, which is also a factor causing the low level of cutting in China's manufacturing industry.
Oil pump industry tool consumption characteristics
Modern oil pump manufacturing industry of mechanical processing and the rapid development of the tool technology, high and new technology has been widely used in processing technology, cutting methods, tool structure, tool material, tool coating and other aspects have been a great difference from the traditional mechanical processing in the past. These circumstances determine the characteristics of the tool used by the users of the oil pump industry: the purchase volume increases and the purchase frequency is frequent, that is, the purchase time is about two months at most. On the one hand, this reflects the mature consumer market, and the tool users of the oil pump industry tend to be more flexible when making budgets, rather than keeping excessive inventory.
In order to achieve the lean production oil pump, oil pump of procurement and inventory management scientifically organizing tool, need to study and explore how to ensure normal operation of production line, reduce the cutting tool inventory capital takes up, optimize the minimum inventory set the cutting tool, cutting tool of the starting point, cutting tool of purchasing purchase frequency and the purchase quantity, Establish effective tool early warning mechanism, emergency mechanism and quick response mechanism, have scientific and effective methods to track and monitor the tool inventory status and purchase status. Super hard tool utilization rate has been significantly improved, such as cylinder block cylinder hole processing in the semi-fine boring and fine boring process, a lot of cubic boron nitride blade, cutting speed has reached a new height, tool life is greatly extended. The performance and quality of the tool directly affect whether the required qualified products can be processed smoothly, whether the tool can meet the requirements of high-speed cutting, how the tool life and tool change frequency are directly affect the operation rate of the production line, affect the processing beat and production efficiency. Whether the adjusted or polished cutting tools can be provided to the production line on time and with guaranteed quality is directly related to whether the production can be carried on normally and continuously. In order to improve production efficiency and reduce the tool change time in the machining process of oil pump parts are increasingly using various composite cutting tools, such as composite, drill hinge composite drilling and boring, compound and other kinds of composite cutting tools, drilling and thread complex expansion tool can satisfy the demands of a lot of special processing, some tool even has developed into the machine, electricity, liquid integration of the device, Has gone far beyond the traditional concept of knives.
Users pay more attention to efficiency improvement and input-output ratio optimization, rather than the simple price factor. New tool structures and blades with new cutting edges and geometric shapes are constantly researched and developed. The tool holding and its connecting parts such as HSK shank, hot sleeve shank, hydraulic shank and other new shank are widely used in nc machine tools and high speed machining.
In the tool materials chosen by domestic oil pump users, carbide tool is the most used, accounting for 64.1%.
Factors affecting the purchasing power of knives
China's oil pump industry is related to the phenomenon of dispersion, low scale and low level. China's oil pump manufacturers are a few with particularly large scale, and the rest are mostly small and medium scale. Therefore, the main consideration of the oil pump industry tool users using tools: cutting efficiency is the most important, followed by the service life, service this factor is more attention, tool production enterprises have also introduced a variety of measures, and buy knife enterprises to complete the production. With the development of super hard cutting tools, hard turning is becoming popular as an economical alternative to grinding. As a result of on-demand procurement, the competition for interchangeable brands in use is also increasing. At the same time, due to the flexibility of user procurement, the market provides a ready entry opportunity for those tool suppliers who have not yet entered the market. Indexable cutting tools have been promoted in China for many years, and the progress is smooth, but the development is not balanced, the user coverage is still lower than the overall tool and welding tool. The connotation of "service" has been developed from simple pre-sale and after-sales service to cutting solutions.
