"Old Sun, you're not confused, are you? So many of us have been working on it for so many days, and we haven't found a problem, and now you actually say three days? Situ Heyun, who was scared by Sun Lin's words for three days, was not prepared at all, and when he reacted, he had already gone downstairs outside the technical department.

"Don't ask so much, I suddenly thought of a possibility just now, I can't explain it to you at this time, only when I go to the scene, I will know the way, all along, we have ignored a detail!" Sun Lin didn't care about explaining anything to Situ Heyun at this time, many times, many things appeared in a flash of inspiration.

Newton figured out the law of gravitation by an apple falling from a tree; Watt was scalded by a kettle of boiling water and made a steam engine; Even, Einstein may have been cheated by someone to come up with the theory of relativity......

All of this is a flash of human inspiration.

"Lao Zhao, you immediately arrange someone to install the other knife storehouse......" Entering the test workshop, Sun Lin said to Zhao Bingbiao, who was taking several workers to inspect the equipment, without refusing.

In the assembly workshop of CNC machine tools, production is carried out in three shifts every day, and there is no extra personnel to be deployed to the test workshop. In the test workshop, all kinds of work need the most experienced and skilled masters to process various parts, and then assemble them by the workers with the best skills. The machining center is the most important project of Jiuyi Heavy Industry now, and some time ago, various sales stations from major machinery factories seduced a lot of masters to Jiuyi Heavy Industry. In addition to the lack of skilled assemblers in the assembly of CNC milling machines, the number of assemblers in CNC lathes is not much.

You must know that Feng Qingping's goods almost gave the CNC lathe assembly workshop in the Northeast No. 1 Machine and Third Branch Factory.

As the production tasks become heavier and heavier every month, Jiuyi Heavy Industry has begun to subdivide various processes and form an assembly line, otherwise, the entire factory will double the number of senior workers. There is also no way to complete the production task. With the subdivision of each process, the process is becoming more and more mature, so that those experienced senior technical workers are liberated from the most cumbersome basic assembly, and are specially used for the fine-tuning and assembly of key parts after the most decoral.

Because the assembly process is becoming more and more mature with the assembly of the CNC lathes produced, the process is becoming more and more subdivided, and even the process is gradually divided, so the assembly fitters of the eighth and ninth levels of Jiuyi Heavy Industry seem to be a little too much. For this reason, Wu Zhongda has looked for Yun Fei several times.

Regarding Wu Zhongda's problem that there are too many senior assembly fitters in the factory, Yun Fei thinks that there are too few top assembly workers in his company. The future development direction of Jiuyi Heavy Industry is the assembly of heavy-duty processing machine tools. Some huge machine tools. The spindle alone has to weigh several tons, and if you are not an experienced top assembler, it is difficult to ensure the accuracy of the assembly.

In this era, there was a large loss of high-level skilled workers in state-owned factories, which Yun Fei did not want to see. Because those workers, once they leave the industry. Even if they don't do their own business for a year or two, their skills will be wasted.

Three days without practicing hands, in the machinery industry. This is especially true among the top workers. Too often, the feeling that it took workers decades to develop is lost in just a few months.

Like what. When the top lathe workers are working, they sharpen the tools at all angles, which are not inferior to the standard theoretical data. But it is easier to use than standard knives, which they have accumulated over decades, and at first glance, it is more accurate than using precision measuring instruments. If such a turner does not sharpen a tool for half a year, basically, they will not be able to reach that peak state again in a few years.

The same is true for milling and fitters.

"Sun Gong, we haven't figured out the problem yet......" Hearing Sun Lin ask him to install another set of tool magazines on the machine tool, Zhao Bingbiao was a little puzzled. Sun Lin just said yesterday that if the problem is not found, it is not allowed to assemble the assembly again, let alone start the machine tool again.

"It's okay, if my idea is right, the problem we are encountering now will not be a problem anymore." Sun Lin said mysteriously to Yang Bingbiao.

"That's ......" Zhao Bingbiao heard Sun Lin, the chief engineer, say this, and immediately began to instruct the workers to put back the various parts that had been dismantled, and then install the spare knife magazine.

"Old Sun, have you found out what the problem is?" Situ Heyun was depressed, Sun Lin, an old product, actually began to sell Guanzi.

From the analysis of various reasons, it is obvious that there is a problem with the control of the machine tool, but the problem cannot be found. The CNC system transformed by Jiuyi Heavy Industry has no problem with the 1060 of Youjia imported from Taiwan, and it is even more powerful than the original system control ability. There is no leakage of the hydraulic pressure, the air pressure has also reached the design standard, and at the same time, the air pressure and hydraulic workstation have no delay and other reactions under the control of such a powerful CNC system.

"Theoretically, it's been found, but we have to wait until they load the knife magazine and conduct a test to find out." Sun Lin smiled and said to his old partner, where is there still the kind of depression that he had a few days ago!

"Then tell me, what's going on? I'm dying. Situ Heyun couldn't find the reason from all aspects of the control system he was responsible for, and now Sun Lin found it, but he didn't tell himself, it was like a cat scratching in his heart.

"I'm not sure right now, I'll wait until it's assembled." After Sun Lin finished speaking, he ignored Situ Heyun's face full of expectations, and turned around and walked towards the office. Just took two steps, turned around again, and walked to Yang Bingbiao, who was lying on the assembly drawing looking for a problem: "Old Yang, please help me remove the clip on the manipulator, and I'll get it in a while." ”

"Could it be that the problem is with the manipulator?" When Situ Heyun heard Sun Lin's words, his heart was full of doubts.

This old thing is too cheap.

actually sold it to himself.

But no matter how you think about it, I can't figure it out, the design of this manipulator, but it is made of imitation of the imported CNC machine tool, the tolerance is smaller than that manipulator, and the precision level is higher.

couldn't figure it out, Situ Heyun could only temporarily put aside the doubts in his heart and wait for Sun Lin, an old man, to reveal the answer.

"Xiaoyun, go and persuade Lao Sun, he has stayed up all night for two consecutive nights...... Now let him go back to rest, he won't do it, not only that, but also forced Zhao Bingbiao to stay all night without closing his eyes...... "Yun Fei, who had just come back from walking around various departments in the office building, had not yet put his butt next to the chair, and Situ Heyun with an anxious face appeared in front of him.

"What?" Yun Fei heard Situ Heyun's words, and immediately bounced forward.

"What's going on?" At the beginning, Sun Lin said that it would only take three days, was he forced by himself? Even so, it shouldn't be, and I didn't force him to come up with results when! Old man Sun is in his sixties, and he actually stayed up all night for two consecutive nights, if something goes wrong, he will be in big trouble.

"After leaving from you and returning to the workshop the afternoon before yesterday, he asked Zhao Bingbiao and them to install the spare knife magazine, and in the past two days, he stared at them for assembly and debugging, and went to the production workshop to urge the workers to rush to make some of the parts he wanted, if I hadn't seen that he was in the wrong state just now, and asked him, where did he know that he hadn't left the office in the past two nights...... "Situ Heyun walked quickly, and while walking, he said to Yun Fei what he had learned.

In the entire Jiuyi Heavy Industry, except for Yun Fei, it is estimated that there is no one who can persuade Sun Lin.

"Stop, stop!" As soon as he arrived at the area of the test workshop used for the test of the knife store, Yun Fei saw several technical personnel saying something to Sun Lin who was sitting on the chair, but Sun Lin kept shaking his head, and urged Yang Bingbiao, who was debugging, to hurry up from time to time.

"Mr. Yun, you are here, help us persuade the teacher......" Seeing that Yun Fei was coming, the few technicians who surrounded Sun Lin said to Yun Fei with anxious expressions.

"Leave him alone, hurry up and finish the debugging, if it's not right, we have to continue to improve......" Sun Lin didn't look at Yun Fei, and yelled at Yang Bingbiao, who was about to stop.

"Old Sun, you better go and rest for a while, we are not in a hurry. A little earlier, a little later, it doesn't have any effect......" For an old engineer like Sun Lin, Yun Fei didn't know how to persuade him. If you want to let him rest strongly, he doesn't work for himself, he can't figure out what kind of stimulation this old guy has been exposed to in the past two days, he just mentioned cooperating with the capital machine, as for this?

Isn't it that he was rejected once by a plane in the capital and lost face. But that's not the case, right?

"It's going to be right away, and this time, there will definitely be no problems! Xiao Yang, how long do you have left? Sun Lin didn't look at Yun Fei, and he didn't know if he said something to Yun Fei.

"Elder Sun, if you continue like this, that kid can only be sorry, you should go back to the capital to retire in the future, if there is any accident in your old age, I can't afford this responsibility." Yun Fei heard Sun Lin's words, and he was angry. immediately collapsed his face and said to Sun Lin in a deep voice.

"Xiaoyun, don't bomb me, really, it's going to be good soon, this time, there will definitely be no more problems. In the past two nights, I have been calculating that the reason why our tool magazine will fall in the process of changing the tool is not because of our design problems, but because the clamp on the manipulator is 0.05mm shorter, and the details determine success or failure!
