392 Heavy duty vehicles for the military industry
For the old man's mouth, Yun Fei didn't know what he said, what he said was that Jiuyi Heavy Industry's heavy-duty CNC lathe, which was mainly aimed at the military industry, was good, or that the price was good.
Such heavy equipment is not so much the production of Jiuyi Heavy Industry, but the CNC transformation of such a heavy lathe by Jiuyi Heavy Industry.
Although even the transmission mechanism has been redesigned and transformed, the price is hundreds of percent profitable. Whether the old man understands this or not, Yun Fei doesn't know the way, but the numerical control transformation of these heavy equipment is not an easy thing in the first place.
Heavy-duty lathes are not as simple as the numerical control transformation of those small lathes, just replace the tool holder, replace the transmission mechanism, and then add a transmission to the circuit that controls the spindle speed and then connect to the numerical control system.
Heavy-duty lathes are only the carriage box and the tool holder part that connect the tool holder, and the weight is counted in tons! It is simply impossible for the ball screw used on ordinary CNC machine tools to drive hundreds of kilograms of tool holders for heavy load cutting.
Besides, it is estimated that not only China, but also Germany, it is difficult to produce precision ball screws with a length of 10 or 20 meters. Therefore, the transmission of such equipment can not use the most common transmission mode of ball screw pair of CNC machine tools, but use a large DC stepper motor to drive the rack and pinion to transmit power to the tool holder weighing hundreds of kilograms for heavy load cutting.
The price of two million is already a very generous price.
If it is sold, it is likely that these two million will become two million dollars!
CNC machine tools are valuable, not only high-end precision CNC machine tools, but also large heavy equipment that the vast majority of machine tool factories cannot produce, and the price is considerable.
This is also the reason why some heavy equipment manufacturers are not only able to survive, but also make high profits. Research funding will even be provided by clients.
Jiuyi Heavy Industry does not even have the production technology of a lathe with a rotary diameter of one meter, and if it does not receive the customer's requirements, it will not even carry out research in this area when the CNC machine tool with a rotary diameter of 600mm has not been made.
Research on rack and pinion transmission mechanism. It is one of the strategic research projects of Jiuyi Heavy Industry. Yun Fei heard Ren Zhiguo, who became the boss of Kamat, say that the domestic aviation system is looking for suppliers of heavy-duty bedroom CNC lathes with a gray turning diameter of 1.6 meters and a length of 20 meters of equipment rails abroad, but has not received any news. Only Germany and the United States have such equipment, and even Japan, which is a devil, does not have the production technology of such super-large heavy equipment!
There are ordinary lathe techniques for the production of such heavy equipment in China, and these techniques are from the Soviet Union! But if you want to produce CNC machine tools, it is not easy.
Anyone who knows about missiles and large rockets knows that in order to be aerodynamic, the drag on the missile during flight is reduced. The head of the missile is very long, and part of the cabin used for the combat parts and observation and guidance parts is cone-shaped.
And the processing of large cone, ordinary lathe processing is very difficult, not only can not guarantee the surface roughness after processing, but also is likely to borrow the knife when using the small supporting plate to form a mechanical running oblique trajectory, can not be completely flattened, which makes the processing cone surface behind and the processing cone surface in front not on a plane, can make the missile on the flight trajectory some uncontrollable problems.
"Deng Lao, 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 to three decimal places. As long as such a tackle can be completed. Our CNC machining centers are fully capable of competing with foreign CNC manufacturers. Our costs are lower than theirs, and we are closer to the market, so the shipping costs are also very low. Sun Lin saw that the front of him was in full swing to assemble or disassemble or inspect the bare metal that was not equipped with a shield. The old man who nodded from time to time explained.
"These guys are three-axis machining centers? Why is it different from what I saw in Huadu CNC at that time? "When he first saw those ugly machines in the closed assembly workshop of Jiuyi Heavy Industry, the old man was very puzzled.
At the beginning, he saw the machining center in Huadu CNC, but it had a very strong sense of high-tech, but now he sees that Jiuyi Heavy Industry does not even have a shell. The equipment is similar to that of ordinary machine tools, and there is a console connected to it with some wires on the outside, and no matter how you look at it, it cannot correspond to those advanced equipment.
"Deng Lao. These are just some semi-finished products used for testing, and the testing place of each equipment is different. Some are used for tool positioning test, some are used for machine tool displacement test, some are used for hydraulic pneumatic test test, etc., these are only part of the machining center in a complete sense, "Sun Lin didn't care whether the old man could understand or not, and directly came out with a lot ......of professional terms.
"Oh!" The old man nodded, although he didn't understand these terms, but he didn't feel the slightest bit embarrassed.
If you don't understand, just ask!
"It's not easy, I didn't expect that these high-tech equipment would have to go through so many tests!" Behind the old man, there were two old men hanging with golden light, and sighed.
"Is there a finished product for my old man to see? Last time I was in Huadu CNC, there was not much time, so I didn't take a closer look. You little boy won't keep it a secret from me, will you? The old man asked Sun Lin, and then said something to Yun Fei that made Yun Fei almost die of his head.
"How can it! Elder Deng, I just keep it a secret from everyone in the world, and I can't keep it a secret from your old man, right? Anyway, we're fellow countrymen, right? Yun Fei saw that the people who were following the old man were all looking at him with a playful look, and his face immediately turned red.
Last time, Admiral Li of the Commission of Science, Technology and Industry for National Defense inspected the work of Jiuyi Heavy Industry, but he did not enter some laboratories of Jiuyi Heavy Industry that had nothing to do with the military. Not to mention those officials of the State-owned Assets Supervision and Administration Commission and the National Development and Reform Commission, but they didn't even enter the door of the experimental building!
When they arrived at Jiuyi Heavy Industry, they were still closed, how could they be happy? Therefore, many people in the central government know that the boss of Jiuyi Heavy Industry is a child!
"These products are mainly developed for domestic users, in line with the usage habits of Chinese, and even the operation panel is improved by the relevant departments in our research laboratory." While taking the old man to the closed area that was used to conduct the three-axis machining center processing test and the four-axis machining center research test of some key parts, Yun Fei introduced to the old man.
"Don't just focus on our domestic market. If an enterprise wants to become 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, and more than 180 percent of the products are low-end light industrial supplies and raw materials that have only been roughly processed or even not processed.
When China will be able to provide a large number of high-tech products to the international market like the United States and other developed countries in Europe, it will be considered to have developed.
"Deng Lao, please rest assured, our products, sooner or later, will compete with those foreign CNC machine tool manufacturers in the international market!" Yun Fei heard the old man make a request for him, and answered the old man seriously.
To sell CNC machine tools to the market of those powerful countries that produce CNC machine tools, their skills can be regarded as recognized by the outside world.
"It's hard!" The old man also said to Yun Fei seriously.
"It's harder. It's all going to be done! My generation can't do it, and our next generation will work in this direction! The solidity of your heart is incomprehensible, and it was not as good as a widow and a weak son. Though I die, I have a son; Sons beget grandchildren, and grandchildren beget sons; Sons have sons, and sons have grandchildren; There is no shortage of children and grandchildren! Sooner or later, one day, we will inherit the glory of our ancestors and stand at the top of the world again! Yun Fei used Beishan Yugong's words to reply to Hequ Zhisuo to show the old man's desire to make the company bigger and stronger.
"Excellent! Go for it. Young man, the world was ours, is yours, and will be. It's still yours! The old man nodded in satisfaction.
It's not terrible to be backward, it's terrible to be backward and still don't know how to catch up!
Hundreds of years ago, China was the world's largest scientific and technological power. Then, from the sixteenth century onwards. China gradually declined, until the founding of the People's Republic of China, and the country was under the leadership of the Communist Party of China. Although there were many detours in the process, and because they underestimated the imperialism of the United States and Britain like paper tigers, they almost dragged China into dire straits.
But these labor pains are normal.
If the country wants to catch up with those countries that have surpassed China for decades or even hundreds of years, it must not follow the old path of those countries, but must follow China's own path.
This road is a shortcut.
Often, there are no shortcuts on the road to a strong country. If you want to take a shortcut, you must remove the thorns and various obstacles on the shortcut one by one.
The two test areas are only separated by a wall, but there is a world of difference between the input and the research inside.
In the research laboratory of the four-axis machining center, there are many research equipment from Germany that have been brought back at a high price. If it weren't for Kamat's channels for so many years, there would be a lot of things that basically couldn't be obtained!
The area next to the door is the area where the three-axis machining center is used for machining tests, and the research projects on the rotary table of the four-axis machining center, the spindle research, the tool magazine tool positioning, and other mechanical research projects are all in the more in-depth area.
Many times, whether it is Wu Zhongda or Ni Lishuang, many people are talking about Yun Fei's things in this regard. (To be continued......)
PS: Thank you for the three great rewards of Tianhai Xiangyun, Sigh ‖, and Harbor.
Thanks to WZHTC, swallowing people's dirt road, small hand battles, seeing Tianchi Mountain, and other big people who can't see the gourd but have voted for the monthly pass.
Yesterday afternoon, many projects of the company need to be delivered, and last night the whole workshop was rushing to work, and the gourd was helping in the workshop, and it was busy until more than eleven o'clock, and there was no time to code words.
