Chapter 216

"Where do you come from the production technology of CNC milling machine? From the Soviet Union? Their own numerical control technology is not very good! How good can the CNC machine tools you have developed? " The whole workshop is 100 meters long. The assembly area of NC milling machine is surrounded by a wall. I don't know who to prevent from peeping into the secret.

Li Lu doesn't 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 studying in this direction. Even if they are studied, they are only some low-grade garbage products that can not compete with foreign CNC machine tools.

Even the capital No. 1 machine tool factory, which is the most powerful milling machine in China, can only import ball screw, servo motor and the most precise spindle from abroad for imitation or assembly. Limited to the factors of domestic casting process and materials, even the most critical columns, bases and saddles used on CNC milling machines can not be compared with foreign ones in terms of performance.

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

Although Li Lu hasn't been to the production workshop to observe, she still knows more about domestic CNC milling machines. Camart now has a general business, which is CNC machine tool trade, and more than 80% 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 and the establishment of more and more processing enterprises, the domestic market, especially the Pearl River Delta and Yangtze River Delta with the greatest vitality, has a sharp increase in demand for CNC machine tools, which represent advanced processing equipment with efficiency.

Although camart has many foreign customers, the number of machine tools they get is far from meeting the needs of the domestic market.

Both Li Lu and Ren Zhiguo are children of the military region's compound. Through their parent-child relationship, they are quite familiar with the senior management in the capital's first machine tool plant. Many times, they will import a small amount of key accessories from abroad through their relationship with foreign countries and provide them to the capital's first machine tool plant to produce some low-end CNC milling machines to meet the urgent needs of some customers.

Yunfei has brought back a lot of engineers and technicians from CNC machine tool related industries from the Soviet Union. Although there are few experts, most engineers from the Soviet Union are practical technicians with rich experience, not those who are superior through relationship. The CNC milling machine they have developed so quickly is not the technology of the Soviet Union. Can it be the technology of the Chinese themselves?

"What are you talking about? If the Soviets had such numerical control technology, they would have had to do all they could to make numerical control machine tools from the devil? " Yun Fei was very unhappy with Li Lu's words.

Needless to say, Li Lu doubted that the CNC machine tool production technology of Jiuyi heavy industry came from abroad, otherwise she would never say so.

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

When Ni Lishuang heard Li Lu say this, he also pouted and stared at Li Lu angrily.

"It has been more than half a year since the design of this CNC milling machine was started and the first batch of testing machines have been assembled. Those Soviets, when they first arrived in Chengdu, Brother Yun Fei had already provided the design idea of CNC milling machine, but there had been no great progress until four months ago, with the participation of academician Sun Lin and academician situ Heyun of the Academy of machinery of the capital Academy of Sciences... "If you weren't worried about Li Lu's continued random speculation, Ni Lishuang will never tell her about the research progress of these CNC machine tools of Jiuyi heavy industry.

"What? You asked grandpa sun and grandpa situ to work for you? " Hearing Ni Lishuang's introduction, Li Lu looked incredible.

Sun Lin and situ Heyun, two academicians, are working at 91 heavy industry?

What kind of enterprise is Jiuyi heavy industry? It is estimated that now the whole machinery industry knows that Jiuyi heavy industry is now the only enterprise fully controlled by a private person in China. Although most of the production equipment and workers belong to the ninth Institute of machinery in name, and the establishment is still in plant 9327, as long as people who understand it know, this is just a helpless move that the military can't feed these workers.

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

At the beginning, Yunfei asked two old guys for help, but it was just for someone to integrate a plate of scattered Soviet engineers. Among these Soviet engineers, the two old guys have not much higher attainments in mechanical and electrical control than the engineers and technicians from these Soviet research institutes.

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

What makes Yunfei most depressed is that these old maozi seem to have got into a dead end. In the design of NC milling machine, if the material strength is not enough, they increase the diameter and thickness of parts, completely adhering to the silly, big and black style of old maozi's various military products and production equipment.

If the cloud does not really produce such CNC machine tools, it is estimated that it will make the whole industry laugh.

"Be careful, it took more than a month to make these two spindles. Don't wait until you break them at the last assembly moment..." before Li Lu came to the door, he heard Sun Lin's familiar voice.

"Grandpa sun is really old and strong. You don't get off work so late!" Li Lu left Yunfei and walked into the area isolated by the wall. She saw Sun Lin nervously staring at three workers in their 40s and 50s to lift a part to a height of more than one person.

Sun Lin turned his head and found that the girl in front of him was Li Lu. His anger dissipated in an instant.

"Lu girl, why did you come here?" Sun Lin is curious about how Li Lu appeared in the assembly workshop of 91 heavy industry.

"I haven't seen you for a long time. I came to see you from the flower capital..." Li Lu came forward and shook Sun Lin's thin arm.

In this action, the clouds and non eyes are about to fall off.

Li Lu, who has never looked like a little woman, would be coquettish!

"Don't do this..." when Sun Lin saw the appearance of Yun Fei, he immediately wanted to understand the purpose of Li Lu's coming here.

Camart was originally a company set up by the military to toss some equipment and electronic products that cannot be produced domestically. Now the international situation is gradually improving. The military has gradually relaxed its control over kamat and gradually weakened its management. At present, the CNC machine tool trade of camart company has a heavy proportion. Li Lu came here and entered the assembly workshop. If she can't guess her purpose, Sun Lin will live in vain for decades in her life.

"Er, 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'm bored. I'll come to see you. By the way, I'll see you study CNC machine tools... "Li Lu didn't feel the panic of being exposed carefully in front of sun Lin. it seems that she hasn't done less of such things.

At this scene, the cloud was stunned.

From knowing Li Lu to now, although we haven't been together for a long time, whether we see it from our own eyes or hear it from other people, Li Lu has never had such an image of a little child. Li Lu's current performance has overturned Yun Fei's understanding of this strong woman.

However, Yunfei found that there was no affectation on Li Lu's face. It seems that Li Lu now is the real Li Lu. What I used to know was just a woman with a mask. Only such Li Lu can make Yunfei feel real.

At the beginning, he pestered Li Lu to recognize his sister. Yunfei just wanted to reduce the import cost of some CNC machine tools and use Li Lu's background to help him get the people he needed from the Soviet network. Later, with the establishment of 91 heavy industry, there was less interest relationship.

Yun Fei is just an ordinary loser. He has always been insensitive to Li Lu, who seems to be a non cannibal. If the radio and communication engineers they need are not in place, Yunfei will never agree with Li Lu to live in his own home.

"Are you coming to see CNC machine tools? It is estimated that by the way, the old man is trying to make me happy... "Sun Lin took off his hand and touched Li Lu's head lovingly.

"Ha ha... Grandpa sun, Yun Fei, that little bastard, is hiding something from me. He doesn't even give me the agency right in the Pearl River Delta... If I hadn't come to Chengdu today, I might not know when these CNC milling machines fill the whole market, These CNC milling machines are actually made by your old man... "Li Lu make complaints about Sun Lin's Tucao's own dissatisfaction, while patting Sun Lin's apple.

"It's rare that Lu, who never flatters anyone, flatters the old man, but this CNC milling machine is not the old man's credit. Come on, what do you want to know? Absolutely know everything and say everything. Our old man has to be worthy of your flattery, doesn't he? " Sun Lin smiled at Li Lu and said.

If you do nothing, you will steal. This girl used to hide far away when she saw herself. But after all, it's a child who grew up watching himself. As long as it doesn't involve some confidential things, I'll say it.

Now Yunfei's 91 heavy industry, what else needs to be kept secret for Li Lu, who still has a military identity behind his back?
