"Where did you come from the production technology of CNC milling machines? From the USSR? Their own CNC skills are not very good! How good can the CNC machine tools you have researched be? "The whole workshop is 100 meters long, and the area where the CNC milling machine is assembled is enclosed by a wall, and I don't know who is trying to prevent anyone from peeping into the secrets.

Li Lu does not believe that Jiuyi Heavy Industry has the ability to independently develop CNC milling machines and machining centers. In the whole country, there are many people who study in this direction, even if they are studied, they are just some of the most low-grade, garbage products that cannot compete with foreign CNC machine tools.

Even the capital No. 1 Machine Tool Factory, which is the most powerful in terms of milling machines in China, can only import ball screws, servo motors and the most precise spindles from abroad to imitate or assemble. Limited to the domestic casting process and material factors, even the most critical columns, bases and saddles used on the CNC milling machine, these large castings, have no way to compare with foreign ones in terms of performance.

In domestic castings, the internal grain structure is not only uneven after microscope magnification, but the largest grain structure will even exceed the smallest several times or even dozens of times! There are also a lot of subtle bubbles and trachoma. The grain structure of foreign castings is very uniform, and under the thousand-fold microscope, it is only the size of a grain of rice, while the big one in China will be bigger than soybeans!

Although Li Lu has not been to the production workshop to observe, he still knows a lot about domestic CNC milling machines. Cammat now has a general business is CNC machine tool trade, and more than eighty percent of the CNC machine tool trade, which accounts for half of the business, are CNC milling machines and machining centers. With the increasing economic vitality of the Pearl River Delta, more and more processing enterprises have been established, and the domestic market, especially the Pearl River Delta and the Yangtze River Delta, which is the most dynamic, have soared demand for CNC machine tools, which represent the efficiency of advanced processing equipment.

Although Kamat has many foreign customers. However, the number of machine tools they get is far from satisfying the thirst of the domestic market.

Li Lu and Ren Zhiguo are the children of the military compound, through the relationship between their parents, they are still quite familiar with the senior management of the first machine tool factory in the capital, many times, they will import a small amount of key accessories from abroad through the relationship with foreign countries, and provide them to the first machine tool factory in the capital to produce some low-end CNC milling machines to meet the urgent needs of some customers.

Yun Fei, this kid, has brought back a lot of engineers and technicians from the Soviet Union who are related to CNC machine tools. Although there are few experts at the level, most of the engineers from the Soviet Union are practical technical talents with rich experience, not those who are in the upper position and the corpse position through the relationship. They are now coming up with a CNC milling machine so quickly, is it not the skills of the Soviets, can it be the skills of the Chinese themselves?

"What are you talking about? If the Soviets had such CNC skills, they would have used all the trouble to build CNC machine tools from the hands of devils? Yun Fei was very unhappy with Li Lu's words.

Needless to say, Li Lu must suspect that Jiuyi Heavy Industry's CNC machine tool production technology is from abroad. Otherwise, she would never have said that.

"You helped get these Soviets, and you don't understand their details!" Yun Fei said to Li Lu angrily.

When Ni Lishuang heard Li Lu say this, she also pouted and stared at Li Lu with anger on her face.

"This CNC milling machine was designed from the ground up. Up to now, the first batch of test machines has begun to be assembled, and it has been more than half a year. Those Soviets, when they first arrived in Rongcheng, Yun Fei's brother had already provided the design ideas of the CNC milling machine. However, there has not been much progress until four months ago, with the addition of Academician Sun Lin and Academician Situ Heyun of the Mechanical Engineering Institute of the Capital Academy of Sciences. Only then did it make relatively rapid progress...... "If it weren't for the worry that Li Lu would continue to speculate, Ni Lishuang would never have told her about the research progress of these CNC machine tools in Jiuyi Heavy Industry."

"What? You asked Grandpa Sun and Grandpa Situ to work for you? Hearing Ni Lishuang's introduction, Li Lu's face was full of incredulity.

Sun Lin and Situ Heyun, two academicians, are actually in Jiuyi Heavy Industry?

What kind of enterprise is Jiuyi Heavy Industry? It is estimated that the entire machinery industry now knows that Jiuyi Heavy Industry is now the only enterprise in China that is fully controlled by a private person. Although most of the equipment used in production and the workers in production still nominally belong to the Ninth Institute of Machinery, and the establishment is still in the 9327 factory, as long as people understand it, they all know it, this is just a helpless move by the military to be unable to support these workers.

Yun Fei smiled, and Ni Lishuang was noncommittal. This is not to let these two academicians work for themselves, but they are crying and begging to be the project chief engineer of their CNC milling machine.

At the beginning, Yun Fei asked two old guys to help, just so that someone could unify a plate of scattered Soviet engineers. Among these Soviet engineers, the two old fellows were not much more accomplished in mechanical and electrical control than the engineers and technicians who came out of these Soviet institutes.

The Soviet Union's achievements in heavy industry are not comparable to those of China.

What makes Yun Fei the most depressed is that these old Maozi seem to have gotten into a dead end, in the design of the CNC milling machine, the material strength is not enough, so the diameter and thickness of the parts are increased, completely adhering to the style of Lao Maozi's various military products and production equipment.

If Yun Fei really produces such CNC machine tools, it is estimated that the entire industry will laugh out loud.

"Be careful, these two spindles took more than a month to make, don't wait until the final assembly moment to be broken by you......" Before Li Lu could reach the door, he heard Sun Lin's familiar voice coming from inside.

"Grandpa Sun is really old and strong, you don't get off work and rest at such a late hour!" Li Lu left Yun Fei and walked into the area that was isolated by the wall, and saw Sun Lin nervously staring at three workers in their forties and fifties lifting a part to a place more than one person high.

Sun Lin turned his head, only to find that the girl who appeared in front of him was Li Lu, and his anger dissipated instantly.

"Lu girl, why did you come here?" Sun Lin was very curious about how Li Lu would appear in the assembly workshop of Jiuyi Heavy Industry.

"It's not like I haven't seen you for a long time, I came to see your old man from the flower capital......" Li Lu stepped forward and hugged Sun Lin's thin arm and shook it coquettishly.

With this action, Yun Fei's eyes were about to fall off.

Li Lu, who has never had the demeanor of a little woman, can actually be coquettish!

"Don't come to this set of ......" After Sun Lin saw Yun Fei appear, he immediately figured out the purpose of Li Lu's coming here.

Camat was originally set up by the military to set up a company to dump some equipment and electronic products that could not be produced domestically from outside. Now that the international situation is gradually improving, the military has gradually loosened its control over Kamat and gradually diluted its management aspects. Now the trade of CNC machine tools of the Camart company has a very heavy proportion. Li Lu came here and entered the assembly workshop, if she couldn't guess her purpose, Sun Lin would have lived in vain for decades in his life.

"Uh, Grandpa Sun. I really came to see you, Brother Zhiguo said that you are now engaged in the research of four-axis machining center in Jiuyi Heavy Industry, I am bored, I came to see your old man, by the way, take a look at your research CNC machine tools......" Li Lu was in front of Sun Lin, without the slightest panic of being carefully exposed, it seems that she has not done such a thing.

This scene, Yun Fei was dumbfounded.

From knowing Li Lu to now, although they have not been together for a long time, whether it is from what they see with their own eyes or hear from others, Li Lu has never had such an image of a child. Li Lu's current performance has subverted Yun Fei's understanding of this strong woman all along.

However, Yun Fei found that Li Lu's face could not be seen to be pretentious at all. It seems that the current Li Lu is the real Li Lu, and the one I knew before was just a woman with a mask. Only this Li Lu made Yun Fei feel real.

At first, he pestered Li Lu to admit his godsister, Yun Fei was just to reduce the import cost of some CNC machine tools, and to use Li Lu's background to help himself from the Soviet Union to network the people he needed. Later, with the establishment of Jiuyi Heavy Industry, there was less interest relationship.

Yun Fei is just an ordinary and ordinary dick, and he has always been grateful to Li Lu, who originally didn't seem to eat fireworks in the world. If it weren't for the fact that the radio and communication engineers he needed were not in place, Yun Fei would never have agreed to Li Lu living in his home.

"You're here to see the CNC machine, right? I guess by the way, this old man is coaxing my old man to be happy......" Sun Lin took off the hand in his hand and touched Li Lu's head with a loving face.

"Huh...... Grandpa Sun, Yun Fei's little bastard is hiding it from me, and he won't even give me the agency in the Pearl River Delta...... If I hadn't come to Rongcheng to see it in person today, it is estimated that when these CNC milling machines flood the entire market, I may not know that these CNC milling machines are actually made by your old man......" Li Lu complained to Sun Lin about the dissatisfaction in his heart while patting Sun Lin's ass.

"It's rare to shoot an old man's ass who never shoots anyone's sycophants, but this CNC milling machine is not the old man's credit. Say, what do you want to know? Absolutely know everything, say everything, our old man has to be worthy of your sycophant, right? Sun Lin said with a smile at Li Lu.

Nothing to be courteous, either a traitor or a thief. This girl used to hide far away when she saw herself. But after all, it's a child who grew up by himself, as long as it doesn't involve some confidential things, it's just about it.

Now Yunfei's Jiuyi Heavy Industry, for Li Lu, who still has a military identity behind his back, what else needs to be kept secret? (To be continued......)
