What level of CNC machine tool in China is in the world? How many foreign technologies are those so-called CNC machines with independent intellectual property rights? These problems are lingering in the hearts of every machine tool person, and I'm afraid that it is difficult for them. The author collects and sorts and looks at this issue from various angles, and this information may give an answer to everyone's questions.
2017 machine tool industry situation
From a broader perspective, in 2017, the operating conditions of China's machinery industry in the first three quarters were better than expected. While the growth rate was higher than expected, the quality of operations improved. For the machine tool industry, based on data analysis released by the National Bureau of Statistics, China's machine tool industry output in the first three quarters of the year: 577,100 gold-cutting machine tools, an increase of 7.49% year-on-year, including 189,100 CNC machine tools, an increase of 0.49% year-on-year; metal forming The number of machine tools was 238,400, an increase of 0.69% year-on-year, of which 21,300 were CNC machine tools, an increase of 15.51% year-on-year. Machine tool numerical control devices were 185,500, an increase of 33.82%; metal cutting tools were 7,518 million, an increase of 17.58% over the same period.
Judging from this set of data, the overall situation of China's machine tool industry looks good this year. The overall growth rate of machine tool output is faster. However, good production does not necessarily mean good quality, but it does not necessarily represent the level of China's machine tool manufacturing. Therefore, whether you are singing well or singing badly, it is better for everyone to put it down first than to look at the assessment of foreign media.
Foreign media evaluation
The figure above is a report of the European Machine Tool Industry Joint Commission (CECIMO) a few years ago, clearly stating that the main competitors of the European machine tool industry are Japan and Taiwan. Japan and Europe are at the same level. The evaluation of Chinese machine tools is a cheap advantage and the technical strength has been gradually improved, but it is not a major opponent and is currently not playing in a grade. It is regrettable that this assessment is still relevant.
In fact, this view is still relatively recognized in the industry. In Japan, Europe, and other countries and regions, machine tool manufacturing is ahead of China in terms of technology and development. However, it is also unfair to define the development level of Chinese machine tools. After all, "there are gaps" and "bad years" are two concepts. The author has also found some netizens' opinions to see what they say.
How to see the netizen

I am doing EDM machines in CNC machine tools. This machine tool industry is somewhat small and belongs to precision machining. The leaders in this industry are the Japanese and Swiss. Japanese companies such as Shadick and Makino, Swiss Archie and Charmilles have now merged into Agie Charmilles. China is a Japanese follower. People who follow the Japanese system and have a good understanding of Sino-Japanese relations should be able to guess. From the early 1970s to the early 1990s, the 20th year of the China-Japan honeymoon, China acquired a great deal of technology from Japan in the past 20 years or so. There are also many sophisticated technologies at that time, and the EDM CNC machine is one of them. . At the time when China was doing technology import from Japan, Japan not only gave software source code, circuit drawings, and system framework diagrams, but also experts in this field came to China for patient guidance. It was almost impossible to say the technical problems encountered. Chinese engineer. Therefore, in the 1990s, China's EDM was very advanced, and it was certainly a little worse than Japan. After all, the most sophisticated people still had to keep some, but the difference in machining accuracy, processing speed, and machine appearance was very small. Now more than 20 years have passed. Do you guess how far China and Japan are in this area? It should be about 20 years away. This is not a joke.

Looking back at the friend's answer, I can't help it. Little incompetence, university student's numerical control, employment for nine years has been in the CNC machine tool company, skipped a slot, began as a US-funded company's CNC company, is currently in the Korean-owned CNC company, has done service, technical support, Process and sales etc. How do you say, at present, China's CNC machine tools are low-end, if the spectators feel uncomfortable, then I change the argument, low-end look like? China's CNC brand equipment, the so-called independent research and development, the vast majority of the system is modeled on FANUC and Mitsubishi, and even Siemens domestic has not imitated (perhaps the short-term insights, did not see), the mechanical part is only the purchase of international brands of zero The components are assembled. In the brochure, the accuracy and key components marked may be the same as the imported equipment, or even higher, but there is still a considerable gap in the service life, rigidity, and dimensional stability. ···

I have been in college for a few years, and I have only calculated by time. The technical gap with foreign high-end CNC systems and CNC machine tools (pay attention to high-end, high-precision) is: 30 years. Of course, it cannot be calculated simply from such an example, but it is intuitive to make the subject have an impression. The rapid development of domestic technology may not be as large as 30 years in reality, because in the present era there are technological conditions and technological means that cannot be compared at that time, which can make up for the gap faster.
In addition to some failures, there are some more positive assessments:
Zhihu User: Wang Guodong
The level of domestic machine tool manufacturing is still good. Learning from Russia on the basis of ordinary equipment starts with a solid foundation. At present, CNC is a popular stage, but it is not a primary stage of popularization. The majority of customers are no longer blindly pursuing low prices. As a result, machine tool manufacturers have also started to take a high-quality route. In terms of CNC system, China can meet the low-end requirements, and the high-end is still dominated by foreign countries. If you really want to say a short board, then I think the material and quality system is a big problem.

Spraying more domestic machine tools, I say encourage words. Our company is a company that uses CNC machine tools to process tubing and casing used in the oil industry. Prior to 2005, the domestic CNC was really not working. The equipment used was in Germany and Belgium. Later, in 2008, it was expanded to use a certain domestic product. The company's, although not the imported equipment, but also meet the requirements for use, plus maintenance services in place, then the updated NC are all used domestic equipment.
In short, most netizens believe that China's machine tools lack core competitiveness and there are still gaps in technology, but they are developing rapidly and have a long-lasting momentum. The author thought that this has been infinitely close to the truth. It may be that people generally lack confidence in the machine tool. In fact, the outlook of the Chinese machine tool is really infinitely bright.
The booming machine tool industry
In 2016, the scale of China's CNC machine tools market has reached 186.2 billion yuan. By 2020, the asset scale of China's CNC machine tools industry will exceed 270 billion yuan, and there will be huge room for future development of the industry.
In the first half of 2017, the import and export of the machine tool industry was US$11.67 billion, which was an increase of 6.52% compared to the first half of 2016 (hereinafter referred to as the same period). Of which, the import was US$6.548 billion, an increase of 4.13% over the previous year; the export was US$5.123 billion, an increase of 9.73% over the same period of the previous year. The import and export deficit was 1.425 billion U.S. dollars, which is a significant improvement over the previous year.
From the above data, we can see that the development of China's machine tools has steadily increased and the prospects are bright. Although China's machine tool manufacturing has such or such deficiencies, but this data is also giving us a dose of strength, the future of China's machine tools, but also can not expect to look forward to.
The author has something to say
Not only the machine tool industry, on the whole, China's manufacturing industry is large but not strong, and there are still large gaps in technological innovation capacity, resource utilization efficiency, and industrial structure levels compared with other manufacturing powerhouses such as the United States, Japan, and Germany. The task of upgrading and improving quality and efficiency is urgent and arduous. However, the momentary gap is not an eternal gap. The release of the Shenyang Machine Tool i5 system and the innovation of Dalian Guangyang's high-end precision manufacturing all prove that our country has the ability to develop into a top-notch technological field. "When the wind breaks through the waves, there will be a time when you hang Yunfan Jihai." Here, the author looks forward to the arrival of the domestic machine tool spring!
