The automobile industry becomes the consumer of the machine tool industry

With the intensified competition in the automotive industry, the cycle of replacement of automotive products has been shortened from decades to three to five years. The combined machine tool auto line has ruled the production of the automotive industry with its high efficiency. At present, the consumption of machine tools in the automotive industry is mainly divided into two levels: First, the four lines used for vehicle production, namely stamping, welding, painting and assembly lines; and secondly, it includes engines, transmissions, steering systems, and brake systems. Processing of automotive parts including transmission systems, suspension systems, etc. Only the press line needs the machine tool in the four lines of vehicle production. The focus of machine tool consumption is on the second level, that is, auto parts processing that accounts for about 70% of the total vehicle equipment value.

The production of automobile parts generally requires four major types of machine tools: metal cutting machine tool production lines. Due to the backwardness of precision forging technology and equipment, most auto parts are processed by cutting; the “four major process equipments” for vehicle manufacturing include complete vehicles. Automatic assembly line, body welding and assembly automatic production line, automatic spraying production line, automatic stamping production line; precision forging production line and manufacturing unit, including die forging, hot precision forging, cold precision forging (cold extrusion), powder metallurgy sintering forging equipment and internal high pressure Forming equipment, etc.; casting production lines include precision casting production lines for the machining of cast iron parts, and die casting machines (manufacturing units) for machining aluminum alloy castings. Others include test equipment, CNC tooling systems, and laser cutting equipment.

As the engine's core functional component, the engine is one of the most important equipments for automobile production. The main components that make up the engine are the cylinder block, cylinder head, crankshaft, camshaft, and connecting rod. The machine tools needed to process these parts are mostly high-efficiency, high-performance, high-reliability CNC machine tools or special machine tools. The cylinder and cylinder head processing flexible production lines are mostly composed of horizontal machining centers; crankshaft processing equipment is mainly car pulling machine tools, CNC crankshaft milling or milling machine, CNC crankshaft grinding machine and crankshaft polishing machine; camshaft processing equipment is mainly cam Axis CNC machine tools and camshaft grinders; and most of the connecting rod processing using special equipment, such as double-face grinders.

In recent years, the development of machining technology has been rapid, and various new technologies have emerged and been applied. In particular, the development of numerically-controlled machine tools has been pioneered, that is, the numerical control machine tools have been specially developed or special-purpose machine tools have been numerically controlled to solve the problems of flexibility and high efficiency. contradiction. At present, the production of automobile parts mostly uses agile production systems composed of high-speed machining centers. As a big country in the automotive manufacturing industry, we must not only master the special technology for equipment manufacturing, but also pay attention to the development of the automotive manufacturing process in the process of transforming into a manufacturing powerhouse. Have their own system development capabilities, improve the reliability of the machine tool indicators, reduce production costs and shorten the new product launch cycle, so that we can truly turnkey projects.
