The market competition of auto parts manufacturing intensifies, and the demand for machine tools is huge

Published on:2022-05-11　　　　 Browse times

The development of automobile industry not only depends on the development of machine tool industry, but also promotes the technological progress of machine tool industry. As an "industrial machine tool", machine tool 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. The prosperity of auto parts processing market has become the theme of machine tool consumption. Relevant analysts believe that the demand for machine tools in the automotive industry has accounted for 40% of the total consumption of the machine tool industry.

It is understood that at present, the consumption of machine tools in the automotive industry is mainly divided into two levels: one is the four lines for the production of complete vehicles, namely stamping, welding, coating and final assembly lines; The second is the processing of auto parts including engine, transmission, steering system, braking system, transmission system and suspension system. Among the four production lines of the whole vehicle, only the stamping line needs machine tools. Machine tool consumption focuses 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 calculated that the demand for machine tools for auto parts processing is more than ten times greater than that of vehicle manufacturers.

As the core functional component of automobile, engine processing equipment is one of the most important equipment in automobile production. With the acceleration of new models in vehicle enterprises, the engine production line has higher and higher requirements for flexibility. Usually, an engine production line needs to be able to produce at least three models. At the same time, the lightweight trend of automobile development makes the material requirements of engine cylinder block and cylinder head change from cast iron to aluminum alloy, which puts forward new and higher requirements for engine processing machine tools.

The main components of the engine are cylinder block, cylinder head, crankshaft, camshaft, connecting rod, etc. Most of the machine tools needed to process these parts are CNC machine tools or special CNC machine tools with high efficiency, high performance and high reliability. The flexible production lines for cylinder block and cylinder head are mostly composed of horizontal machining centers; Crankshaft processing equipment mainly includes turning and drawing machine tools, CNC Crankshaft internal or external milling machines, CNC Crankshaft Grinding Machines, crankshaft polishing machines, etc; Camshaft processing equipment is mainly camshaft CNC lathe, camshaft grinder and so on; The connecting rod processing equipment is mostly special equipment, such as double end grinder and so on.

With the increasing market competition, customers put forward more stringent requirements for the products, technologies, services and products of automobile suppliers, and pay more attention to the safety and other performance of automobiles. With the implementation of national energy conservation and emission reduction measures, the fuel consumption and pollution degree of vehicles have also attracted much attention. Labor costs in China's market are also rising. These factors lead to unprecedented pressure on auto parts enterprises, and put forward higher requirements for the reliability, production efficiency, accuracy and cost performance of parts processing. The substantial increase of automobile production capacity will inevitably require the substantial increase of automobile parts production capacity. In the face of the gradually increasing labor cost in China, automobile parts manufacturers are required to adopt machine tools with higher efficiency, greater complexity and higher degree of automation to solve the contradiction between manufacturing cost and labor cost.
