Automatic gauge blank hinders industry development

At present, as the basic tool industry of the machine tool bed tool industry, the basic component parts and functional components are controlled in developed countries such as Germany, Japan, Switzerland, and the United States, which not only involves security, but also leads to large outflow of profits. Chinese machine tool, where did spring go?

The tool industry is mainly tools, measuring tools and functional components (including accessories). Although there are some 04 special support, it is weaker than the machine tool.

The importance of cutting tools in machining is not recognized by top management. The machine tool is called the Machine Tool in foreign countries. There is no tool, and the machine tool has no use at all. Whether a machine tool can exert 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 item. In the numerical control workshop of Xi'an High Voltage Switchgear Factory, the workshop has 40 to 50 CNC machine tools, and the annual consumption of tooling costs 8 million yuan. The high-end cutters used by users, especially the ones matched with CNCs, are basically imported from foreign countries, such as Shanga, Sumitomo, and Welle, etc. The famous cutting tool companies basically monopolize the high-end market in China. Alas, China is still a big country producing tungsten powder, but also exports. Big country.

We are a large producer of abrasives, such as corundum, silicon carbide, etc. These are energy and pollution-intensive industries, so there are opportunities for survival in the market. In 2013, sales of superhard materials increased by 12.3% compared to 2012. There are also some exports. , but some high-end products also rely on imports because their quality affects the precision and finish of the final finishing.

The status quo of the measuring instrument: The automatic measuring instrument is basically a weak link for the monopoly measuring device of foreign enterprises. The high-grade instruments of the measuring room, such as roundness meter, surface finish meter, coordinate measuring machine, gear comprehensive inspection instrument, dual-frequency laser interference Instruments, etc. are computerized and digitized. Some of its measuring sensors have reached nanometer level, can process data, analyze the measured object, and can find the weak links in the processing process. As for the long grating, circular grating is basically monopolized by German company Dr.Heidenheim .

In particular, the automated measuring instrument is a blank, basically monopolized by developed countries such as Marposs, CarlMahr, and Reinishow. In the mid-1960s, a complete set of pneumatic measuring instruments was introduced and the Central Plains Instrument Factory was built. However, it did not advance with the times and continued to innovate. No "eyes", no measurement How can we judge whether the processed parts are qualified, can't carry out real-time online measurement and data processing, can't find any problems in the processing, how can we improve the production process?

The status quo of functional components: quality and quantity can not be compared with foreign manufacturers Comrade Liang Xunzhen and several old experts in the machine tool industry put forward the concept of functional components shortly after the reform and opening up. The functional components contain machine tool accessories. Industry and government leaders generally agree.

Although we have some professional production companies, such as rolling screw sets manufactured by the Nanjing Technology Equipment Factory with a long history, we can not match the quality and quantity with famous foreign manufacturers. Moreover, there are few professional factories. There are some well-known machine tool groups, such as Dalian Machine Tool, Shen Machine, and Han River, all of which test and develop functional components, but this is not yet a climate. According to an industry expert, the total output of our rolling parts is not as good as one in Taiwan.

Precision, super-precision bearings for high-speed, high-precision, and high-load bearings for machine tool spindles 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, Harbin Bearing Factory had a high-precision bearing branch specializing in the manufacture of machine tool spindles. The C-class bearings (high-precision grades) with model number 3182112 were produced. They were of good quality. Now that they are not produced, isn't it? Is it sad? Where is socialization specialization? Functional components are necessary for large industrial production. In addition, the production chain of the machine tools is also very long, such as hydraulic, pneumatic, electronic control systems, cutting oil, lubricants, who is the domestic high-quality supplier?

Concerns raised: As a lesson from history, we can learn that the workers, blades, measuring tools, and functional components used in supporting high-end and middle-end hosts have to resort to foreign suppliers. Some comrades said that with the current economic globalization, these high-quality functional components and accessories can be purchased globally. This cannot be said to be unreasonable. However, in-depth observation, as the basic parts and functional components as the machine tool industry are controlled in Germany, Japan, Switzerland, the United States and other developed countries, not only involves security, but also a lot of profit outflow, do we do not need to think deeply?

As for the numerical control system and its servo drive device that are matched with CNC machine tools, it will not be the climate until now. In the late 1950s, we researched and developed CNC systems synchronously with the world. After the reform and opening up, it also adopted methods such as the introduction of technology and cooperation in production, which laid the foundation for further independent development. The effect thus far has been unsatisfactory. I believe leaders at all levels and related companies are doing their best, but they are still not successful. Some trial production, industrialization, the author can not understand, CNC system control in Germany, Siemens, Japan Fanuc hands, but also talk about what machine tool country?

The reality is the continuation of history and the beginning of tomorrow. You can learn about history by taking history as a mirror. You can learn about others by taking people as a guide. 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, both materially and financially, but it still seems to be no match for the "invisible hand" of the market economy. In the context of further comprehensive and in-depth reform of the “market allocation of resources plays a decisive role”, the machine tool industry will face a more severe situation. Leaders of enterprises must respond to preplans, pre-establish rules, and do not pre-define them.

The analysis of the above phenomenon is beyond our understanding. I have been in the lean years and have been away from the machine tool industry for 30 to 40 years. Thought and technology are behind the modern machine tool manufacturing industry. Out of an old machine tool worker complex. , Ask some questions to think about it, and teach it to leaders, experts, professors, and entrepreneurs.

One of the considerations: Mainstream companies entering the “bigger and full” business model are influenced by the “Heroes of GDP theory” and inherited from the factors of planned economy in the past. Chinese mainstream machine tool companies have entered the “big and full” business model. .
