Automobile industry promotes the technological progress

Reviewing the development history of automobiles, it is not difficult to see the role of advanced equipment and manufacturing technology. The level and quality of automobile manufacturing depend on the level of equipment. At the same time, more than half of the investment in automobile industry is used to buy metal processing machine tools, among which imported machine tools account for about 80%. Therefore, the international competitiveness of automobile industry depends on the advanced equipment and manufacturing cost.

In recent years, China's automobile industry has become the main consumption of machine tools, accounting for about 70% of the total consumption of machine tools in China. So the industry will have automotive equipment to support the automobile industry and machine tool industry half of the sky. There are three possibilities: first, the consumption of China's automobile industry accounts for about half of the output value and profit of the equipment manufacturing industry; Second, China's auto industry has become the first driving force for industrial growth. Thirdly, the development of automobile industry not only depends on the technological progress of machine tool industry, but also leads the development of machine tool industry.

With the intensification of competition in the automobile industry, the renewal cycle of automobile products is shortened from several decades to three to five years, and the automatic line of modular machine tools cannot adapt to the lack of flexibility. The combination machine tool automatic line dominates the production of automobile industry with its high efficiency. The advent of flexible automated production lines in the 1980s has accelerated the replacement of vehicle products and improved the efficiency and flexibility of companies, which is one reason why we now see dozens of new cars on the market each year.

At the same time, the multi-variety mass manufacturing system is a new automotive parts manufacturing system in the era of diversification, which is the latest technological innovation of manufacturing technology to meet the requirements of diversity and economy. A variety of mass manufacturing systems include workpiece feed machine tools and compact flexible automatic assembly lines.

And the most commonly used machining machine tools for auto parts that is the workpiece feed type machine tool on this and has a revolutionary development: from the vertical car type to the processing center type; Having a set of arrayed cutting tools, or a dynamic cutting tool shaft. These tools are modular, according to the processing requirements set, processing object change when the tool is very convenient. Such a multi-functional or composite machining machine tool can be achieved in addition to the clamping base surface of all processing. At the same time, the chip removal is convenient, suitable for mass automatic production. The modular cutting tool can also be changed when the processing object is changed, so the cycle of processing new products is greatly shortened and the cost is greatly reduced. At the same time, the tool change time is short, omitting most of the action of the traditional machining center tool change, thus saving the tool change time.

With technological progress, the updating speed of automobile products will be faster and faster, and the increasing demand for diversity makes the number of models increase sharply; At the same time, with the increasingly fierce competition in the engine market, the uncertainty of production volume increases. We believe that the parting manufacturing system can cope with the universal module production scheme for various parts processing, which is more suitable for the production of multiple varieties and small batch sizes. At the same time, because the workpiece and tool movement chain is greatly shortened, the machine tool structure is simplified, and the relative position accuracy requirement between the parts of the machine tool is reduced, thus reducing the difficulty of machine tool manufacturing.
