The status quo and development trend of CNC machining technology (2)

The performance of domestic CNC gear machine tools has been roughly equivalent to the international level. Except for some high-precision CNC gear processing machines (DIN 5~6) and high-precision CNC gear grinding machines (DIN 2~3), they still need to be imported. Replace imported products.

Electric machining machines, in addition to precision electric machining machines, can meet market needs. CNC electric machining machines still have gaps in machining accuracy, surface roughness, machining methods, and software.

Domestic CNC grinding machines can basically meet the needs of the domestic market. However, some high-precision, high-efficiency, composite CNC grinding machines in CNC grinding machines rely on imports, such as CNC precision universal cylindrical grinding machines, CNC precision forming surface grinding machines, CNC crankshaft grinding machines, CNC camshaft grinding machines, and large-scale CNC machines. There are many imports of cylindrical grinding machines and various CNC high-efficiency special grinding machines.

The domestic CNC heavy-duty gold cutting machine has great advantages in price, and the price is only about half of that of similar foreign products. Through the independent development and actual production application and assessment in recent years, in addition to individual super-heavy, multi-axis control, Most of the sophisticated domestic products have not been approved, and most of them have been recognized by domestic power generation, metallurgy, mining and other equipment manufacturers.

In general, the market satisfaction of domestic CNC machine tools is still not high, low-end melee, high-end failure. In 2009, imported machine tools still reached 5.9 billion US dollars, including 3.56 billion US dollars for gold cutting machine tools and 1.34 billion US dollars for metal forming machine tools. Imported are almost all high-end CNC machine tools and automatic lines.

Third, the gap with foreign countries

1. Gap of business philosophy

The "market-oriented" concept of some domestic enterprises is short-sighted and narrow-minded. It is limited to the sales of products and simply sells products. The so-called after-sales service is to repair machine tools. Focusing on customers, focusing on customer needs, providing solutions and creating value for customers, from product competition to service competition has not become the core business philosophy of the company. Especially for the needs of high-end customers, domestic machine tool companies often provide unnecessary supply and cannot be supplied. Although the situation has improved, it has not changed fundamentally.

Some domestic enterprises ignore the importance of technology integration and limit themselves to the production of machine tools. They do not realize that software and hardware integration will bring great potential to create value for customers. Leading machine tool companies in foreign countries generally regard software and hardware integration as an important way to adjust product structure. For example, DMG's Power Tool package, Mazak's Cyber ​​Production management system, GF AgieCharmilles' Smart Machine process monitoring system, Siemens 828D's ShopMill and Program Guide programming software.

2. Key technology gap

Compared with the machine tool manufacturing powerhouse, China's CNC machine tools still have obvious gaps in terms of structure, technology level, innovation and research and development capabilities. Basic technology, key technologies and common technologies are not yet fully understood. Focusing on customer needs, developing personalized products, developing specialized CNC machine tools, and providing users with a comprehensive solution is weak.

In particular, the development of high-performance CNC systems and core functional components lags behind the mainframe, and the market share is very low, which has become the main bottleneck restricting the development of China's CNC machine tool industry.

The gap between key technologies is ultimately reflected in the reliability and accuracy stability of domestic CNC machine tools. Even the large number of CNC machine tools that can be produced in China and have mature technology, such as vertical machining centers, small and medium-sized horizontal machining centers, CNC lathes, etc., are slightly inferior in terms of reliability and precision retention. Foreign companies therefore have a considerable market share.

3. Development strategy gap

When developing a development strategy, domestic companies often develop a certain product to become the main line. Most of them are strategies to follow and imitate the products of foreign leading companies. Competitive enterprises should shift their sights beyond their competitors to the looming and potential needs of customers, cross the existing competitive boundaries, and transform from the positioning choices under the established market structure to changing the market structure, that is, “guide the market”. Guiding the market is a proactive strategy. It is characterized by self-originating new technologies, new products, and meeting the evolving needs of the market, improving the customer's technical level, maximizing profits for customers, and exploiting new profits for themselves. space. It will change the structure of the market, provide advanced products to the market, guide customers to new products, use new products, and benefit from new products.

Fourth, the road to the machine tool power

China's machine tool industry must realize the transformation from big to weak and strong and big. The basic way to become a world machine tool powerhouse is to change the development mode, adjust the industry and product structure, and realize industrial upgrading.

With China's transition from a “manufacturing power” to a “manufacturing power”, the demand structure and level of CNC machine tools in the core manufacturing sectors of the national economy will change significantly. Automobiles, high-speed railways, aerospace, energy and shipbuilding industries all require a new generation of CNC machine tools with high precision, high efficiency, automation and energy saving. There is huge room for the upgrade of China's CNC machine tool industry, especially high-end CNC machine tools.

We should clearly understand that if China wants to become a machine tool powerhouse, other countries will not sit idly by, and the way to obtain technology will surely encounter a new blockade. From now on, we must rely on independent innovation. Establish an open, socialized R&D system that combines production, study and research with enterprises as the mainstay.

Innovation is inseparable from talents, and it takes more than a generation of hard work to move toward a machine tool. There is a shortage of high-end talents, especially the lack of leading talents in high-end CNC machine tool design, CNC systems and functional components development, as well as the lack of senior technicians and the lack of a comprehensive management talent with an international vision. The shortage of high-end talents has become a deep-seated reason for restricting the rapid and sustainable development of China's CNC machine tool industry.
