Development of automobile industry is dependent on the development of the machine tool industry, but also to promote the technological progress of the machine tool industry. As " industrial machine tools," the machine is an important equipment in automobile production, automobile manufacturing accounted for the total investment in fixed assets 2 /3 of a direct impact on the manufacturing cost of the car. Spawned a thriving automobile spare parts market, has become the subject of machine tool consumption. The analysis considers the automotive industry demand for machine tool industry has accounted for 40% of total consumption.
It is understood that the automobile industry for machine tool consumption is mainly divided into two levels : one for the production of four automobile lines, namely stamping, welding, painting and assembly line ; Second, including the engine, transmission, steering system, braking systems, transmission systems, suspension systems, including machining auto parts. Vehicle production four lines need only punch line machine. The focus of machine tool consumption in the second level, which represents the value of the vehicle equipped with about 70% of all auto parts processing. Some experts have estimated that the demand for auto parts machining machine tool OEMs to ten times larger than the above.
As a core feature of the car, engine machining equipment is one of the most important equipment in automotive production. With the new vehicle business models to accelerate, the engine production line for flexible increasingly demanding, often need to be able to meet the engine production line to produce at least three models. Meanwhile, the lightweight vehicle development trend makes the engine block, cylinder head material requirements change from cast iron to aluminum, which is also proposed for the engine machine tools new and higher requirements.
The main component parts of the engine are cylinder block, cylinder head, crankshaft, camshaft, connecting rod. Machined parts required for these machines are mostly efficient, high performance, high reliability CNC machine or a dedicated CNC machine tools.
With the growing competition in the market, customers propose more stringent requirements for the technologies, services and products, pay more attention on the safety performance of the car. Automobile production capacity significantly enhance inevitable require significantly enhance of the auto parts production capacity, and the face of a gradual increase in Chinese labor costs, requires the production of auto parts enterprises to adopt more efficient and a more complex, more automated tools to resolve conflicts of manufacturing costs and labor costs.(Source: auto.qq.com)
