The ninth-level fitter, this legendary existence, is the king of skilled workers.

A top-level worker in the most advanced type of work knows even more about theory than an engineer, and the actual operation is unimaginably strong.

Xie Kai has been reborn for so long, and he has never been in contact with any ninth-level fitter, even if it was the master who brought him in the previous life, he never went to look for it, not that he did not forget the kindness of the master, but knew that the workshop where his master was now was not something he could easily enter.

Even in his 359 workshop, there are no ninth-level fitters.

No matter how foolish Zheng Yucheng is, he will not hand over this kind of base strategic-level master to Xie Kai, and he will not need to engage in tank models.

"Have you contacted the base?" Xie Kai asked Zheng Yucheng.

"It's already on the way, and it should be there tomorrow night. Zheng Yucheng nodded.

Xie Kai looked at him worriedly, and before he could speak, Zheng Yucheng knew what he wanted to say, and smiled comfortingly, "Don't worry, I didn't let Yun Shi go back to pick them up, they took the train to Jiayuguan to transfer to another airport, and took Yun Ba, which was used by the military to transport supplies, although Yun Ba's environment was poor, the safety was guaranteed." ”

Hearing this, Xie Kai breathed a sigh of relief, "Yun Ten is too unsafe, this is the best." ”

Zheng Yucheng looked at him, "They are the real strategic talents of the base, whether it is their experience or their craftsmanship, no high-precision equipment can reach it." I am glad that you have such thoughts, and they are the guarantee of the base. ”

Xie Kai nodded.

Chen Degui, who was on the side, asked incomprehensibly, "Is it so mysterious?"

"You'll know when you see it. This is the legendary level, where can there be a small unit? A larger unit, there can be three or two, it is already very rebellious. Xie Kai said to him.

In mechanical manufacturing, it is difficult for people who do not have access to the top manufacturing accuracy to understand what a grade 9 fitter is.

The only bad thing is that the production efficiency is too low, high-precision machining equipment, especially the top CNC machine tools, processing for one or two hours, with manpower, may take several months.

If you don't pay attention, the whole part will be scrapped.

Europe and the United States understand that top skilled workers are not easy to train, so they develop CNC equipment.

The Soviet Union has experience in this field that is unparalleled in the world, and in addition to the huge territory that has been developed for more than half a century, the number of talents in this field is huge.

Otherwise, it will be difficult for them to send satellites into the sky and build a space station with their stupid and coarse manufacturing process.

Zhao Wenju of the Taibai Factory transported the scrapped equipment to Qinfei, and Sun Daoqian, who had been notified by Zheng Yucheng, personally came forward and asked them to unload the equipment to the cargo warehouse of the test airport.

In the evening, it was loaded again with the liberation car of the Qin Fei transport convoy and transported to the 691 factory overnight.

No one questioned such a cumbersome operation.

Don't let them pay anyway.

Shaanxi Provincial Institute of Optoelectronics attaches great importance to the lithography machine equipment of the 691 factory to get the 1 micron manufacturing process, and Chen Tongan, director of the Fengcheng Optoelectronics Research Institute, personally led their core technical personnel to the 691 factory.

"Director Chen, hard work!" Zheng Yucheng smiled after holding Chen Tongan's hand.

Chen Tongan shook his head with a smile, "What are we working so hard for? It's you guys who can actually get something of this level." ”

"We're lucky too. Zheng Yucheng didn't mention it at all, this was taking advantage of Taibai Factory.

If it weren't for the high level of the 404 base, the other party wouldn't believe it, or even take a look.

"Where's the device? Let's take a look. After Zheng Yucheng and the others shook hands with the experts brought by Chen Tongan one by one, Chen Tongan said impatiently.

The top chip production line in China is the 5-micron production line imported from Toshiba in Factory 742, and many designs of the Optoelectronic Research Institute cannot be turned into products to test performance.

Under laboratory manufacturing conditions, accuracy is difficult to control.

"Director Chen, comrades, please follow me. Chen Degui led the group into the workshop where the equipment was stacked.

"Don't you know how precise these things are?" Entering the workshop and seeing the messy equipment inside, Chen Tongan frowned and asked Chen Degui.

Even if the two were a family five hundred years ago, he didn't have any good attitude.

It doesn't matter if Zheng Yucheng doesn't understand, Chen Degui They are professionals, how can they not understand the precision of these equipment? A slight bump may have a serious impact on the machining accuracy.

"Director Chen, this batch of equipment only arrived last night, and I haven't had time to finish it yet. Please come here just to fix it. Before we got it, it was in the garbage...... Otherwise, we won't be able to do it. Zheng Yucheng was not dissatisfied.

Chen Tongan was relieved when he heard his explanation.

Scrapped equipment, they will only pay attention to it if they can't get it.

Immediately, he began to let his technicians, with the cooperation of the technicians of the 691 factory, inspect these equipment to determine what exactly was broken.

"Three lithography machines are the core, two German and one Swiss. In this regard, it may not necessarily be as accurate as the domestic production of RB, and after the repair, we will definitely be able to get unexpected surprises in this regard. "Hou Weigui and the others already know about the situation of these devices, especially Xu Mingsheng and them.

"Are you going to be placed in such a workshop?" Chen Tongan asked Chen Degui.

Chen Degui looked at Zheng Yucheng.

With such sophisticated equipment, the ordinary production workshop in front of me cannot be placed at all, and if it is repaired, there will be problems due to changes in the environment in a few days.

Dust, temperature, humidity and everything else affects the machining accuracy of these world's top production equipment.

"As soon as we are sure that it can be repaired, we will immediately start building a dust-free and constant temperature workshop. Both these devices and chip production processes have demanding requirements for the environment. Zheng Yucheng didn't know, he hadn't discussed this aspect before.

Xie Kai spoke.

Chen Tongan looked at him and nodded.

The waiting process was long, from morning to afternoon, the technical experts of the Fengcheng Optoelectronic Research Institute did not complete the inspection work.

Their inspection is far more detailed than Hou Weigui and others, although China cannot provide such high-precision equipment, but the principle of the same type of optoelectronic equipment is the same.

With the assistance of the 691 factory and the technicians from the Taibai factory, the equipment was not connected to the power supply, and all kinds of obvious problems were carefully recorded.

"I haven't turned on the power supply to let the equipment run yet, and I have found so many problems, just these, it's not easy to fix!" After constantly receiving a summary of various equipment conditions, Chen Tongan reminded Zheng Yucheng.

Zheng Yucheng knows that maintenance is not easy, "What is the reason why it is not easy to repair?"

"Many parts are very small, and the machining accuracy is too high, whether it is the material or the processing process, we may not be able to achieve it. Chen Tongan frowned.

"That's not a problem. Zheng Yucheng said with confidence.

"During the transportation process, these equipment were not well preserved, and many places were broken, and our domestic testing instruments could not provide such high accuracy. ”

"It's still not a problem. ”

Zheng Yucheng's words made Chen Tongan smile bitterly.

The official in front of him should not understand technology, otherwise he wouldn't have said that it would not be a problem.

If it's really not a problem, China can't even copy these devices?

"Director Chen, don't treat me as a joke. All you have to do is ask for it, and my people will get the parts out for you!" Zheng Yucheng said confidently.

He didn't have such confidence in himself.

For the top bulls in the base, he is full of confidence.

"The legendary ninth-level fitter, it's not easy to get these things up, let alone so much equipment. Unless you can mobilize a large number of ninth-level fitters to cooperate with each other and concentrate on tackling key problems. Chen Tongan looked at Zheng Yucheng and said, "This is not only a demanding requirement for manufacturing accuracy, but also a more stringent precision requirement for the final assembly." There are not many ninth-level fitters in China, most of them are concentrated in aerospace, and everyone has a lot of tasks......"

His meaning is obvious, Zheng Yucheng wants to count on the ninth-level fitter to solve the problem of manufacturing accuracy and assembly accuracy, it is not an easy thing.

Unless Zheng Yucheng can borrow a large number of ninth-level fitters from the aerospace system.

There is simply no possibility.

When aerospace did not get the top CNC machining equipment, the final finishing of many high-precision core components had to rely on them to guarantee.

Even so, if there is a mistake, the part is scrapped.

"You think we need to ask the space side to borrow people? It's a good thing that they don't ask us to borrow people. Zheng Yucheng said disdainfully.

Originally, there were related sub-projects in the base, from aerospace to aviation, tanks to nuclear submarines.

The ninth-grade fitters were all mobilized from various units in those years.

In the past few years, the production business of the base has relied on the finishing of ninth-level fitters.

Later, the tasks of each unit became fewer and fewer, and the funds were tight, and the ninth-level fitters of the 404 base gradually became idle.

The finishing of the key core components of the avant-garde air defense missile and the finishing of the precision hydraulic parts of the Hongqi excavator are all processed by the numerical control equipment of the precision machining workshop and then processed by them for follow-up processing.

As a result, production efficiency is also higher.

The top fitters of the 404 have become more idle.

This is a serious waste.

"In terms of accuracy, there is no need to worry about it. Tonight, there will be 14 grade 9 fitters coming. Zheng Yucheng said calmly.

"So many?" asked Chen Tong'an incredulously.

Zheng Yucheng just laughed and stopped talking.

After ten o'clock in the evening, several 212 jeeps drove in the dark to Zheng Yucheng, who was waiting in front of the office building of the headquarters of Factory 691.

More than a dozen people got out of several cars, most of them in their fifties, wearing gray overalls and emaciated.

Some of them even had gray hair and walked with an unsteady feeling.

It's no different from an ordinary old man.

"Are these the legendary ninth-level fitters? It's no different!" Chen Degui thought about the appearance of many ninth-level fitters, and felt that they were all full of red faces, full of energy, fairy wind and bones, and sharp eyes......

But these people in front of him are too ordinary.
