How does the machine tool industry meet the development needs of the automotive industry?

The main body of machine tool consumption in the automotive industry is divided into two levels. One is the four lines used for the production of complete vehicles, namely stamping, welding, painting and assembly lines; the other is the engine, transmission, steering system, braking system. , automotive parts processing including transmission systems and suspension systems. Among the four lines of the whole vehicle production, only the press line requires a machine tool, and the current domestic press line can fully meet the requirements. The focus of machine tool consumption is on the second level, that is, the processing of auto parts, which accounts for about 70% of the total equipment value of the whole vehicle. Some experts have estimated that the demand for machine tools for auto parts processing is 10 times larger than that of OEMs.

As the engine of the car core, its processing equipment is one of the most important car equipment. As new models accelerate into the market, the requirements for flexibility in engine production lines are stronger. Usually, an engine production line must meet the requirements for producing three models. The lightweight of the car makes the engine block and cylinder head material change from cast iron to aluminum alloy, which puts some new higher requirements on the machine tool.

The main components that make up the engine are the cylinder block, cylinder head, crankshaft, camshaft, connecting rod, and so on. Most of the equipment for processing these parts are high-efficiency, high-performance, high-reliability CNC machine tools and special CNC machine tools. Among them, the flexible production lines for cylinder and cylinder head processing are mostly composed of horizontal machining centers; the crankshaft processing equipment is mainly for truck-lawing machine tools, CNC crankshaft internal milling or external milling machines, CNC crankshaft grinding machines, crankshaft polishing machines, etc.; camshaft processing equipment is mainly It is a camshaft CNC lathe, camshaft grinder, etc.; the connecting rod processing is mostly dedicated equipment, such as double-face grinding machines.

At present, the value of imported equipment accounts for 90% or even 95% of the production of automobile engines in China. The localization rate of tools used in engine production lines is over 10%. The gap between domestic machine tools is mainly manifested in three aspects. The first is the lack of integration technology, the lack of technology to integrate process systems and logistics systems into flexible manufacturing units or production lines. Second, the reliability and stability of domestic machine tools still needs to be improved. Especially in the mass production mode of automobiles, the contradiction is particularly prominent; the third is that the service of domestic enterprises to users still stays in the after-sales service stage, and the automotive industry generally requires the provision of overall process equipment solutions. These gaps and problems should cause the machine tool manufacturers to pay full attention.

China's auto industry is in an unprecedented period of rapid development, and still shows strong development potential under the impact of the international financial crisis. The automobile industry has become the mainstay of machine tool consumption. The relevant analysis believes that its proportion has accounted for 40% of the total machine tool consumption. The machine tool industry should firmly grasp the strategic opportunity period of the automobile industry in the next 10 years of development, aim at the current direction of automobile development, and aim at the world's automobile manufacturing technology to encourage and support small-displacement vehicles, energy-saving and environmental protection, new energy vehicles and other hot projects. And the development of cutting-edge technology in equipment, significantly increase the market share of domestic machine tools, and gradually achieve import substitution, and common development with the domestic automotive industry.

Potash Fertilizer can promote the photosynthesis of crops, promote crop results and improve the cold resistance and disease resistance of crops, thereby increasing agricultural output. Potassium is present in the plant as a free potassium ion, which promotes the metabolism of carbohydrates and nitrogen; controls and regulates the activity of various mineral nutrient elements; activates various enzyme activities; controls nutrient and water transport; Internal pressure prevents the plants from wilting.
