Auto parts companies call for "efficient machining solutions"

As raw materials rise, labor costs rise, and market competition continues to intensify, auto parts companies call for "efficient processing solutions."



Auto parts manufacturing has a great demand for machine tools

China's auto industry is in an unprecedented period of rapid development, even in the context of the international financial crisis, it is still "outstanding". The strong development of the automotive industry has given birth to the booming automotive parts processing market and has become the theme of machine tool consumption.

The development of the automotive industry relies not only on the development of the machine tool industry, but also on the technological advancement of the machine tool industry. As an "industrial machine" machine tool, it is an important equipment for automobile production, accounting for about 2/3 of the total investment in fixed assets of automobile manufacturers, which directly affects the manufacturing cost of automobiles. According to the analysis, the demand for machine tools in the automotive industry has accounted for 40% of the total consumption of the machine tool industry.

Auto parts manufacturing has huge demand for machine tools

The auto parts industry is an important part of the auto industry. The development of the auto industry provides a huge market for the development of auto parts companies. According to relevant reports, the total output value of China's auto parts industry in 2010 exceeded 1.4 trillion yuan. With the continued rapid development of the automotive industry, the auto parts industry will also usher in a bright future.

It is understood that the current automotive industry's consumption of machine tools is mainly divided into two levels: First, four lines for the production of complete vehicles, namely stamping, welding, painting and assembly lines; second, including engines, transmissions, steering systems, Processing of automotive parts including brake systems, transmission systems, and suspension systems. Of the four lines produced by the entire vehicle, only the press line requires a machine tool. 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 more than ten times larger than that of automakers.

Auto parts processing puts new demands on machine tools

As the core functional component of the car, engine processing equipment is one of the most important equipment for automobile production. With the acceleration of new models of vehicle manufacturers, the requirements for flexibility in engine production lines are getting higher and higher. Usually, an engine production line needs to be able to meet at least three models. At the same time, the lighter trend of automobile development makes the conversion of the engine block and cylinder head material from cast iron to aluminum alloy, which puts new and higher requirements on the engine processing machine.

The main components that make up the engine are the cylinder block, the cylinder head, the crankshaft, the camshaft, and the connecting rod. Most of the machines required to process these parts are high-performance, high-performance, high-reliability CNC machine tools or special CNC machine tools. The flexible production lines for cylinder and cylinder head processing are mostly composed of horizontal machining centers; the crankshaft processing equipment is mainly truck-drawing machine tools, CNC crankshaft internal milling or external milling machines, CNC crankshaft grinding machines, crankshaft polishing machines, etc.; camshaft processing equipment is mainly Camshaft CNC lathes, camshaft grinders, etc.; and the connecting rod processing equipment is mostly dedicated equipment, such as double-face grinders.

As competition in the market continues to intensify, customers are demanding more stringent requirements for automotive suppliers' products, technologies, services and products, and are paying more attention to the safety of automobiles. With the implementation of national energy conservation and emission reduction measures, the fuel consumption and pollution level of automobiles have also received much attention. Labor costs in China's market are also rising. These factors have led to an unprecedented increase in pressure on auto parts companies, and put forward higher requirements for the reliability, production efficiency, accuracy and cost performance of parts processing.

Urgent need for efficient machining solutions

The sharp increase in automobile production capacity will inevitably require a substantial increase in the production capacity of auto parts. In the face of the increasing labor costs in China, auto parts manufacturers are required to consider adopting higher efficiency, greater compoundity and higher automation. In the face of this trend, Swiss Tonas has introduced a multi-spindle automatic turning center for the efficient machining of precision shaft parts in automotive parts.
