As Tang Zifeng said, the military 432 factory, which has undertaken the numerical control transformation of 17 40 imported machine tools, is facing a gluttonous feast at this time. The value of this business is more than 4 million, but the 432 factory is a little unbearable.

"What's going on, I still can't find out the reason?"

In workshop No. 205 of the 17th Institute, Gu Yuanyuan, the chief engineer of the 432 factory, shouted in a low voice at his subordinates Xu Ping and Zhang Guoqing, and at the same time secretly glanced at several 17 engineers not far away with his eyes, for fear of being heard by them.

Military 432 Factory is a military system specializing in the research and manufacture of CNC machine tools. In the years when foreign countries carried out a blockade of China's high-tech industrial equipment, Factory 432 developed more than a dozen kinds of industrial control chips with its own strength, assembled them on several large machine tools, and produced China's first batch of CNC machine tools, which were used in the production practice of important military departments.

After the improvement of relations between China and the West, Factory 432 introduced some semiconductor manufacturing equipment and industrial control chip design technology and patents from Japan, Germany, the United States and other countries, and the chip development capability has been greatly improved.

Then, just when the 432 factory was planning to make a big move, the state began to compress the military spending, and the production tasks of the 432 factory were seriously reduced, almost to the point of making ends meet. Due to the shortage of funds and the continuous decline in the treatment of employees, many employees have jumped jobs and left, and the rest of them are also complaining, which makes the factory director feel a lot of pressure.

Factory 432 did not think about saving itself. Like many military enterprises in those years, Factory 432 took advantage of its own advantages to develop civilian products, and successively produced tape recorders, washing machines, air conditioners and other products.

This time, the leaders of the 432 factory showed an old face and contacted the Chutian 17 Institute to jointly apply for a 5 million yuan technical transformation fund from the Science and Technology Industry Commission for the renovation of a batch of old machine tools in the 17 Institute, the most important of which is to use the industrial control chip independently developed by the 432 factory to carry out numerical control transformation of 40 ordinary machine tools imported in the 80s. As for the 17 institutes that added some private goods when applying for funds, hoping to renovate a batch of old domestic machine tools, the 432 factory was too lazy to care. This is not what they are good at, 17 are willing to find other companies to do it, and 432 factory does not care.

In the early years of the 432 factory, the production of CNC machine tools was to fill the domestic gap and break the blockade of CNC machine tools in China. As long as everything has political significance, economic considerations are less important. The cost of those CNC machine tools produced by the 432 factory is higher than that of imported machine tools, and the production efficiency is not as good as that of imported machine tools, so it is not very competitive in the market. This time, the reason why we started from the refurbishment of machine tools, rather than falsely accusing the enterprises under the Commission of Science and Technology to purchase the machine tools they produce, is also due to this reason.

Gu Yuan is the chief engineer of Factory 432, and he is also a leading electronic technology expert in China, and more than a dozen industrial control chips in Factory 432 have been successfully developed under his auspices. This time, the Science and Technology Commission approved the renovation plan jointly proposed by the two enterprises and allocated 5 million yuan of funds, Gu Yuan took a team to 17 institutes and began to study the transformation plan of the imported machine tools.

The 17 imported machine tools were also introduced after the overall improvement of relations between China and the West. At that time, of course, there are all CNC machine tools in the international market, but the price of CNC machine tools is more than twice as high as ordinary machine tools, in the case of very tight national funds, especially in the case of serious shortage of foreign exchange, 17 of course it is inconvenient to choose CNC machine tools, but chose a number of ordinary machine tools.

The processing capacity and machining accuracy of these imported machine tools are far better than those of domestic machine tools, and once they are put into production, they have become the main machine tools of 17 institutes. After more than ten years of use, some machine tools have also appeared wear and tear, in addition to the background of the increasing popularity of CNC machine tools, these ordinary machine tools appear to be somewhat outdated, and the production efficiency can not keep up with the production requirements of 17.

For the 17 institutes, the best choice is, of course, to apply for funds from the state to import new CNC machine tools, but the leaders also know that such a request is impossible to be approved by the Commission of Science and Technology. An imported grinding machine is worth hundreds of thousands of dollars, which is equivalent to more than 3 million yuan, where can the country get this money. At this time, the 432 factory came to the door and threatened to help the 17th Institute transform the original ordinary machine tool into a CNC machine tool, and by the way, it can also repair the worn parts and restore the production capacity of the equipment.

The leaders of the 17th Institute are actually skeptical about whether the 432 factory can do this. But people find the door, and do not need 17 to pay, just let 17 sign on the application, why not the leadership If the Commission of Science and Technology agreed to refurbish the machine tool, the 432 factory helped 17 to change this batch of imported machine tools into CNC machine tools, after all, the benefit is still 17.

In this way, the two units jointly submitted a plan. 17 aspects also used some spring and autumn brushwork, for example, that the refurbishment of machine tools belongs to the benefit of no expense, with a few million dollars, it can make the original cost of hundreds of millions of dollars to import machine tools rejuvenated, can replace new imports, benefit the country and the people, Yunyun. The Commission of Science and Technology also felt that this was a good idea, so it allocated the money.

Of course, there is another reason for the Science and Technology Industry Commission to do this, that is, knowing that the 432 factory is about to be uncovered, it is also necessary to find a name to subsidize them. This reason, of course, will not be written in official documents.

Ordinary machine tools for numerical control transformation, in the current is a fashionable thing, many enterprises engaged in internal innovation, will also do. However, there is no ready-made model for how to install CNC modules on each machine tool, and engineers can only explore it on site. Gu Yuan brought people to the 17th Institute to explore this model. By the way, when Tang Zifeng and the others came to the 17th Institute, Gu Yuan and the others had been staying in the 17th Institute for almost a month.

In the past month, Gu Yuanyuan's mood was still good in the first ten days. He comprehensively inspected the 40 machine tools that 17 institutes hoped to transform, and put forward some transformation ideas, which were praised by 17 engineers led by Xiao Ming. Both the guests and the host were happy, and they were happy at the dinner together no less than five times.

But all of this changed when the engineers of the 432 factory removed the spindle bearing of an imported grinding machine and planned to observe whether there was wiring space inside the fuselage. The spindle bearing was smooth when it was removed, but it was even more difficult to put it back on.

No, after seven or eight days of tossing, the bearings still failed to return to the correct position, but there was a little deviation from the original position. The grinding machine is done for precision machining, the bearing is misaligned, and it is difficult to ensure even the basic scale parameters during processing, let alone precision, which is the life of Gu Yuan.

"When you dismantled it, didn't you pay attention to where it should be installed?" asked Gu Yuan to his subordinates.

"We noticed, it's where the line is drawn on it. But the problem now is that we can't fit the bearings back to this place seamlessly, and no matter how we install them, we will have to deviate from this line. Female engineer Xu Ping said with red eyes. It's not that she is crying and her eyes are red, but she has spent several days in front of this grinder, staring at the position of the bearing device every day, and her eyes are red.

"Hell, how did the Germans put it in the first place, and why it couldn't be put back when it was removed," Gu Yuan muttered.

Zhang Guoqing reminded: "Chief Engineer Gu, I think there should be some skills in this. If we are doing this now, if the bearing or bearing hole is worn, it will be troublesome. ”

"Of course I do. Gu Yuan said angrily, "But what kind of skills are there, do you figure it out?"

"No ......" Zhang Guoqing made a bitter face, "Chief Engineer Gu, I studied electronics, and I am not good at mechanics." ”

"Xiao Xu, you are from a mechanical background, do you see any problems" Gu Yuan asked Xu Ping again.

Xu Ping, who has already run for five, can still be called "Xiao Xu" in Gu Yuan's mouth, if she is compared with Tang Zifeng, it is not too much to call her an aunt. She shook her head and said: "What Xiao Zhang said makes sense, the German machine tool assembly method is not the same as ours." We didn't pay attention, we removed this bearing, and then we wanted to install it back, but it was difficult. I wondered if the Germans had any special tools that we wouldn't have been able to put back together without them. ”

"What then," Gu Yuan asked.

Xu Ping offered a suggestion: "Or, let the family check the information quickly and see if they can find any inspiration." Let's put this grinding machine down and study the whirlwind mill. ”

The so-called "home" refers to the main factory of Factory 432. They were guests in 17 houses, and they couldn't find any information. There is a lot of information in the data room of the 432 factory, including some foreign machine tool periodicals, if you arrange someone to check, maybe you can find a little bit of bearing installation skills. Of course, if you can't find the relevant content from the information in the factory, you may have to arrange someone to go to the capital to find other information, which is what the factory needs to coordinate.

Gu Yuan also knows the truth that if you want to hurry, you can't reach it, he is also from an electronic background, although he is no stranger to machinery, but Xu Ping said that he can't take it, so he doesn't have to bother. He said: "It seems that I can only call back and ask my family to arrange for someone to check the information." However, when we said that we would disassemble this grinding machine, we told the 17 institutes that we would take it apart and put it back on them. I can't pretend to go back now, how can I tell Chief Engineer Xiao?"

"I can only tell the truth. Zhang Guoqing said, "Actually, we have been tossing here for several days, and their people can see it clearly." Although he didn't ask us directly, he guess it was to save face for us. If we pretend to be confused, we will not be above board enough. ”

"Alas, it seems that I can only tell the truth to Chief Engineer Xiao. Tanihara sighed.
