At present, the basic parts and components and functional components of the basic tool industry as the machine tool bed tool industry are controlled in developed countries such as Germany, Japan, Switzerland, and the United States, which not only involve safety, but also make a large amount of profits outflow. Where is the spring in China?
The tool industry is mainly tools, gauges and functional components (including accessories). Although there are some special support for 04, it is weaker than the machine tool.
The importance of tools in machining is not recognized by the top. The machine tool is called a machine tool (MachineTool) in foreign countries. Without a tool, the machine tool is useless at all. Whether a machine tool can achieve efficiency and processing performance, the tool accounts for a considerable proportion.
Although the tool is not as expensive as a machine tool, it is a consumable. In the CNC workshop of Xi'an High-voltage Switch Factory, the workshop has 40 or 50 CNC machine tools, and the annual cost of cutting tools is 8 million yuan. The high-end tools used by users, especially the tools matched with CNC, are basically imported from abroad, such as Shangao, Sumitomo, Wilt and other famous tool companies, which basically monopolize the high-end market in China. It is a big country that produces tungsten powder and exports. Great country.
We are a major abrasive producer, such as corundum, silicon carbide, etc. These are energy and pollution intensive industries, so there are still opportunities to survive in the market. In 2013, sales of superhard materials increased by 12.3% compared with 2012, and some exports However, some high-end products also rely on imports because their quality affects the precision and finish of the final finishing.
The status quo of measuring instruments: automatic measuring instruments are basically monopolized by foreign companies
The measuring instrument is a weak link. The high-end instruments in the measuring room, such as roundness meter, surface finish meter, coordinate measuring machine, gear comprehensive checker and dual-frequency laser interferometer, are all computerized and digitized. Some of its measuring sensors have reached the nanometer level, and can be processed by data. The analyzed objects can be analyzed to find the weak links in the processing. As for the long gratings and circular gratings, they are basically monopolized by the German company Dr.Heidenheim. .
In particular, the automatic measuring instrument is a blank, basically monopolized by Marposs (Italian), CarlMahr (De) and Reinishow (English) in developed countries. In the mid-1960s, the company introduced a complete set of pneumatic measuring instruments and built a new Zhongyuan measuring instrument factory, but did not keep pace with the times and continued to innovate. There is no "eye", no measurement how to judge whether the workpiece is qualified, real-time online measurement and data processing, and there is no problem in the processing process. How to improve the production process?
Status of functional components: quality and quantity cannot compete with foreign manufacturers
Liang Xun, a former director of machine tool tools, and several old experts in the machine tool industry proposed the concept of functional components shortly after the reform and opening up. The functional components include machine tool accessories. This concept has been widely recognized by industry and government leaders.
Although we have some professional manufacturing companies, such as the rolling screw pair produced by Nanjing Craft Equipment Factory with a long history, we can't match the famous foreign manufacturers in terms of quality and quantity, not to mention the professional factories. There are some famous machine tool groups, such as Dalian Machine Tool, Shenji, Hanjiang, which are all research and development of water testing functional components, but it is still not a climate. According to an industry expert, the total production of rolling parts in our country is not as good as that of a Taiwanese company.
As for the high-speed, high-precision, high-load precision and ultra-precision bearings for machine tool spindles, they are basically supplied by SKF of Sweden, FAG of Germany, Seiko of Japan, and Timkin of the United States. Before the reform and opening up, the Harbin Bearing Factory had a high-precision bearing factory specializing in the manufacture of machine tool spindles. The model C-bearings of the type 3182112 (high-precision grade) were produced. The quality is good, and now they are not produced. Is this not the case? Very sad? What is the specialization of socialization? Functional components are required for industrial production. In addition, the industrial chain of production machine tools is also very long, such as hydraulic, pneumatic, electronic control systems, cutting oil, lubricants, who is a domestic high-quality supplier?
Concerns raised: learning from history can be known as
The tools, blades, gauges and functional components used in the mid- to high-end mainframes have to be turned to foreign suppliers. Some comrades said that the current economic globalization, these high-quality features and accessories can be purchased globally, which cannot be said to be unreasonable. But in a step-by-step observation, these basic components and functional components of the machine tool industry are controlled in developed countries such as Germany, Japan, Switzerland, and the United States. Not only do they involve safety, but they also cause a lot of profits to flow out. Do we not need to think deeply?
As for the CNC system and its servo drive that are compatible with CNC machine tools, it has not become a climate. In the late 1950s, we researched and developed CNC systems in parallel with the world. After the reform and opening up, it also adopted the methods of introducing technology and co-production, which laid the foundation for further independent development, and the effect has not been satisfactory so far. I believe that leaders at all levels and related companies have done their best, but they have not succeeded. Some trial production, industrialization can not, the author can not understand, CNC system control in Germany, Germany, Fanuc hands, but also talk about machine power?
Reality is the continuation of history and the beginning of tomorrow. Learning from history can be used to know how to make a difference. It should be said that after the reform and opening up, the government's "tangible hand" has given tremendous support to the machine tool industry in both material and financial terms, but it still seems to be no match for the "invisible hand" of the market economy. Under the circumstance of further comprehensive and deep reform of "the market allocation of resources plays a decisive role", the machine tool industry will face a more severe situation. The leaders of enterprises must have a response plan, pre-planned, and not pre-emptive.
The analysis of the above phenomena is puzzling. I have been in the past few years, leaving the machine tool industry for thirty or forty years. Ideological and technological lag behind the modern machine tool manufacturing industry, out of an old machine tool worker complex. Ask questions, teach leaders, experts, professors and entrepreneurs.
