The **abstract** highlights the critical role of the machine tool industry in driving the development of the automotive sector. It's not just about the growth of the automotive industry itself, but also about the technological advancements within the machine tool industry. As a key "industrial machine," machine tools play a vital role in automobile manufacturing, accounting for roughly two-thirds of the fixed asset investment by automakers. This directly impacts the cost and efficiency of vehicle production.
The booming market for auto parts processing has become a central focus for machine tool consumption. According to industry analysis, nearly 40% of total machine tool demand comes from the automotive sector. Currently, the consumption of machine tools in the automotive industry is mainly divided into two categories: first, the four main lines for complete vehicle production—stamping, welding, painting, and assembly—and second, the processing of individual auto parts such as engines, transmissions, steering systems, braking systems, and suspension components.
Among these, only the stamping line requires traditional machine tools, while the majority of machine tool usage occurs at the second level—the processing of auto parts. This segment accounts for approximately 70% of the total equipment value of a complete vehicle. Some experts estimate that the demand for machine tools in auto parts manufacturing is more than ten times greater than that for整车 (complete vehicle) production.
As a core component of the car, engine processing equipment is one of the most essential machines in the automotive industry. With the rapid introduction of new vehicle models, the flexibility of engine production lines has become increasingly important. A typical engine production line must be capable of handling at least three different models. Additionally, the growing trend toward lighter vehicles has led to a shift from cast iron to aluminum alloy for engine blocks and cylinder heads, which places higher demands on the precision and performance of engine processing machines.
The main components of an engine include the cylinder block, cylinder head, crankshaft, camshaft, and connecting rod. Most of the machines used to process these parts are high-performance CNC or specialized CNC machines. Flexible production lines for cylinder and cylinder head machining typically consist of horizontal machining centers. Crankshaft processing involves truck-drawing machines, CNC internal or external milling machines, grinding machines, and polishing devices. Camshaft processing relies on CNC lathes and grinders, while connecting rod processing often uses dedicated equipment like double-face grinders.
With increasing market competition, customers are placing stricter demands on automotive suppliers, focusing on product quality, technology, service, and safety. At the same time, government policies promoting energy conservation and emission reduction have heightened attention on fuel efficiency and environmental impact. Rising labor costs in China have also intensified pressure on auto parts manufacturers. These factors have led to higher expectations for the reliability, efficiency, accuracy, and cost-effectiveness of parts processing.
The surge in automobile production capacity will inevitably require a significant increase in the output of auto parts. In response to rising labor costs, manufacturers are now turning to more advanced, efficient, and automated machine tools to address the growing challenge between production costs and labor expenses.
