For the old population, Yun Fei doesn''t know whether he is talking about the heavy CNC lathe mainly aimed at military industry, which is made by 91 heavy industry, or whether the price is good.


    Such heavy equipment is not so much produced by Jiuyi heavy industry as the numerical control transformation of such heavy lathe by Jiuyi heavy industry.


    Although even the transmission mechanism has been redesigned and transformed, the price has hundreds of profits. Whether the elderly understand this or not, Yunfei doesn''t know, but the NC transformation of these heavy equipment is not an easy thing.


    The heavy-duty lathe is not as simple as the NC transformation of those small lathes. It is just to replace the tool holder, replace the transmission mechanism, and then install a transmission in the circuit to control the spindle speed, and then connect the NC system.


    Heavy duty lathe is only the chute box and tool rest part connected with the tool rest, and the weight is counted in tons! It is impossible for the ball screw used on the ordinary NC machine tool to drive the tool holder weighing hundreds of kilograms for heavy load cutting.


    Besides, not only China, but also Germany, it is estimated that it is difficult to produce precision ball screw with a length of 10 meters or 20 meters. Therefore, the transmission of such equipment can not adopt the transmission mode of the most common ball screw pair of NC machine tools, but uses a large DC stepping motor to drive the gear rack to transmit power, and the tool holder weighing hundreds of kilograms is used for heavy load cutting.


    The price of two million yuan is already a very kind price.


    If sold, it is likely that this two million will become two million dollars!


    The value of CNC machine tools is not only high-grade precision CNC machine tools, but also large-scale heavy equipment that most machine tool factories cannot produce. This price is considerable.


    This is also the reason why some heavy equipment manufacturers can not only survive, but also have high profits. Research funding will even be provided by customers.


    Jiuyi heavy industry has no production technology for lathes with a rotation diameter of one meter. If it has not received the requirements of customers, it will not carry out this research when it has not developed CNC machines with a rotation diameter of 600mm.


    The research of rack and pinion transmission mechanism is one of the strategic research projects of Jiuyi heavy industry. Ren Zhiguo, who has become the boss of camart, said that the domestic aviation system is looking for suppliers of heavy bedroom CNC lathes with ash turning diameter of 1.6 meters and equipment guide rail length of 20 meters abroad, but has not received any news. Only Germany and the United States have such equipment, and even devil''s Japan does not have such super large heavy equipment production technology!


    There are ordinary lathe technologies for producing such heavy equipment in China, but these technologies come from the Soviet Union! But it is not easy to produce CNC machine tools.


    People who know about missiles and large Rockets know that in order to comply with aerodynamics and reduce the resistance suffered by missiles during flight, a long part of the missile''s head is conical outside the cabin used to install combat components and observation and guidance components.


    For the processing of large cones, ordinary lathes are very difficult, which not only can not ensure the surface roughness after processing, but also can not be completely leveled when borrowing the tool when using the small support plate to form a diagonal track of mechanical operation, so that the rear processing cone surface is not on the same plane as the front processing cone surface, It will cause some uncontrollable problems in the flight trajectory of the missile.


    "Mr. Deng, this is the test workshop of our three-axis machining center and four-axis machining center. These three-axis machining centers are tackling the problem of precision entering the three digits behind the decimal point. As long as we can complete such a breakthrough, our CNC machining centers can compete with foreign CNC manufacturers. Our cost is lower than theirs. Moreover, we are closer to the market, and the transportation cost is also very low. " Sun Lin said to the old man who nodded from time to time when he saw that these bare machines in front were being assembled or disassembled in full swing or tested without shields.


    "These guys are three-axis machining centers? Why is it different from what you saw at Huadu CNC? " When he first saw those ugly machines in the closed assembly workshop of Jiuyi heavy industry, the old man was very confused.


    At first, he saw the machining center in Huadu CNC, but he had a very strong sense of high technology. Now, he sees that the equipment of Jiuyi heavy industry, which has no shell and is similar to ordinary machine tools, is connected to a console with some lines outside, which can''t correspond to those advanced equipment.


    "Mr. Deng, these are only semi-finished products for testing. The testing places of each equipment are different. Some are used for tool positioning test, some are used for machine tool displacement detection, some are used for hydraulic and pneumatic test, etc. in a complete sense, these are only part of the machining center... "Sun Lin directly came up with a lot of professional terms regardless of whether the old man can understand it or not.


    "Oh!" The old man nodded. Although he didn''t understand these terms, he didn''t feel embarrassed at all.


    Ask if you don''t understand!


    "It''s not easy. Unexpectedly, these high-tech equipment have to go through so many tests!" A man behind the old man with two shining golden lights sighed.


    "Is there any finished product for my old man to see? Last time I was in Huadu CNC, I didn''t have much time, so I didn''t take a closer look. Your little boy won''t keep a secret from me, will he? " The old man asked Sun Lin and then said something to Yun Fei that made Yun Fei almost kill himself.


    "How can I! Mr. Deng, even if I keep it secret from people all over the world, I can''t keep it secret from you, can I? At least we are fellow countrymen, aren''t we? " Yun Fei looked at the old man with a joking look, and his face turned red immediately.


    Last time, Li Shang from the Commission of science, technology and industry for national defense will inspect the work of 91 heavy industry. He did not enter some laboratories of 91 heavy industry that have nothing to do with the military. Not to mention the officials of SASAC and NDRC, but they didn''t even enter the gate of the experimental building!


    How can they be happy when they are shut down at the September 1 heavy industry? Therefore, many people in the Central Committee know that the boss of 91 heavy industry is petty!


    "These products are mainly developed for domestic users and conform to the use habits of Chinese people. Even the operation panel has been improved by the relevant departments in our research laboratory." While taking the old man to the closed area separated for processing test of three-axis machining center and research test of some key parts of four-axis machining center, Yun Fei introduced to the old man.


    "Don''t only focus on our domestic market. If an enterprise wants to be bigger and stronger, it must enter the international market and be recognized by users in the international market!" The old man is very angry about China''s export trade, which is growing faster and faster every year. More than 18% of the products are low-end light industrial products and raw materials that are only rough processed or even unprocessed.


    When will China be able to provide a large number of high-tech products to the international market like those developed countries in the United States and Europe.


    "Mr. Deng, please rest assured that our products will compete with those foreign CNC machine tool manufacturers in the international market sooner or later!" Yunfei heard the old man''s request and answered the old man seriously.


    To sell CNC machine tools to the market of powerful countries that produce CNC machine tools, their technology is recognized by the outside world.


    "It''s hard!" The old man said to Yun Fei with the same seriousness.


    "No matter how difficult it is, we must do it! My generation can''t, and our next generation will work hard in this direction! Your heart is solid, solid can not be thorough, never like a widow and weak son. Although I die, how can there be a son; Sons and grandchildren, and grandchildren and sons; Son and son, son and grandson; Children and grandchildren are infinite! Sooner or later, we will inherit the glory of our ancestors and stand on the top of the world again! " Yun Fei used the words of Yugong Beishan to answer the wise old man in Hequ to show the old man his wish to make the company bigger and stronger.


    "Good! Work hard, young man, the world used to be ours, is yours now, and will still be yours in the future! " The old man nodded with satisfaction.


    Backwardness is not terrible. What''s terrible is that backwardness doesn''t know how to catch up!


    Hundreds of years ago, China was the world''s first scientific and technological power. Then, after the 16th century, China gradually declined until the founding of new China. Under the leadership of the Communist Party of China, the country began to work hard. Although there were many detours, it almost dragged China into deep water because it underestimated the paper tiger imperialism such as the United States and Britain.


    But these pains are normal.


    If the country wants to fully catch up with those countries that have surpassed China for decades or even hundreds of years, it cannot follow the old path of those countries, but must follow China''s own path.


    This road is a shortcut.


    Often, there is no shortcut on the road to becoming a powerful country. If you want to take a shortcut, you must remove the thorns and obstacles on the shortcut one by one.


    The two experimental areas are only separated by a wall, but the investment in them is very different from the research.


    In the Research Laboratory of the four-axis machining center, there are many research equipment bought back from Germany at a high price. Yun Fei doesn''t know what the performance of these equipment is. Anyway, he only knows that the price is old and expensive. If it weren''t for camart''s channels for so many years, many things would basically be impossible to get!


    The area near the door is the area used by the three-axis machining center for machining test. It is more in-depth in the area with the research on the rotary worktable of the four-axis machining center, the research on the spindle, tool magazine tool positioning and other mechanical research projects.


    Many times, whether Wu Zhongda or Ni Lishuang, many people are talking about Yunfei in this regard.
