Chapter 266

"Lao sun, aren't you confused? So many of us haven't found out the problem for so many days. Now you say three days? " At first, Sun Lin pulled him to run. Stu Heyun, who was frightened by Sun Lin for three days, was not prepared. When he reacted, he went downstairs outside the technology department.

"Don't ask so many questions. I suddenly thought of a possibility just now. I can't explain it to you now. I won't know until I go to the scene. We've ignored a detail all the time!" Sun Lin couldn't care to explain anything to situ Heyun at the moment. Many times, many things appeared in a flash of light.

Newton got the law of gravitation from the apple falling from the tree; Watt was scalded by a kettle of boiling water and made a steam engine; Even Einstein may have been fooled by people before he came up with the theory of relativity

All this is a flash of human intelligence.

"Lao Zhao, you should arrange someone to install the other tool magazine..." entering the test workshop, Sun Lin said to Zhao bingbiao, who was taking several workers to check the equipment.

In the assembly workshop of CNC machine tools, production is carried out in three shifts every day. Originally, there was no redundant personnel deployed to the test workshop. In the experimental workshop, various types of work require the most experienced and skilled teachers to process various parts, and then the same skilled workers to assemble them. The processing center is now the most important project of Jiuyi heavy industry. In addition, some time ago, various sales stations lured many teachers from major machinery factories to Jiuyi heavy industry. In addition to the lack of skilled assemblers in the assembly of CNC milling machines, the number of assemblers of CNC lathes is not much.

You know, Feng Qingping almost finished the NC lathe assembly workshop in the Northeast No. 1 machine No. 3 branch.

As the monthly production tasks become heavier and heavier, Jiuyi heavy industry has begun to subdivide various processes and form assembly lines. Otherwise, there will be no way to complete the production tasks for the doubled senior workers in the whole factory. With the subdivision of each process, the process is becoming more and more mature, which liberates those experienced senior technicians from the most cumbersome basic assembly and is specially used for the final fine adjustment and assembly of key parts.

Because the assembly process is more and more mature with the assembly of the CNC lathe, the processes are more and more subdivided, and even begin to divide the processes step by step, there are a little more assembly fitters of grade 89 in Jiuyi heavy industry. To this end, Wu Zhongda has looked for Yunfei several times.

For the problem that Wu Zhongda thinks there are a lot of senior assembly fitters in the factory, Yunfei thinks there are too few top assembly workers in his company. The development direction after 91 heavy industry is the assembly of heavy processing machine tools. For some huge machine tools, the spindle alone has to weigh several tons. If it is not an experienced top assembler, it is difficult to ensure the assembly accuracy. Even if it is finally guaranteed, the efficiency will be painful.

In this era, there is a large loss of senior skilled workers in state-owned factories, which Yun Fei does not want to see. Because once those workers leave this industry, even if they don't do their own business for only one or two years, their technology will be wasted.

It is particularly obvious in the machinery industry, especially among the top workers. Many times, the feeling that it takes decades for workers to develop will be lost in just a few months.

For example, when the top lathe workers are working, the various angles of their sharpening tools are no worse than the standard theoretical data, but they are easier to use than the standard tools. This is what they have accumulated for decades. When they look at it, it is more accurate than using precision measuring instruments. If such lathe workers don't sharpen tools for half a year, basically, they can't reach that peak state for several years.

The same is true for milling and fitter.

"Sun Gong, we haven't found out the problem yet..." Zhao bingbiao was a little confused when he heard Sun Lin ask himself to install another set of tool magazine on the machine tool. Sun Lin only said yesterday that if the problem is not found out, it is not allowed to assemble the assembly, let alone start the machine tool.

"It's all right. If I'm right, the problem we're facing now won't be a problem anymore." Sun Lin said mysteriously to Yang bingbiao.

"That's ok..." Zhao bingbiao heard Sun Lin, the chief engineer, say so, and immediately began to order the workers to install all kinds of disassembled parts back, and then install the spare tool magazine.

"Lao sun, have you found out the problem?" Situ Heyun was depressed. Sun Lin, an old man, actually began to sell off.

From the analysis of various reasons, it is obvious that there are problems in the machine tool control, but the problems can not be found. The CNC system reconstructed by 91 heavy industry has no problem when it is installed on the Youjia 1060 imported from Taiwan. It is even more powerful than the original system control ability. The hydraulic pressure has not leaked, and the air pressure has reached the design standard. At the same time, the air pressure and hydraulic workstation have no response such as delay under the control of such a powerful CNC system.

"In theory, I found it, but I can't know until they install the tool magazine and test it." Sun Lin smiled and said to his old partner, where is the kind of depression a few days ago!

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

"I'm not sure now. I'd better wait until it's assembled." Sun Lin said that, ignoring situ Heyun's expectation, he turned and walked towards the office. After two steps, he turned around and came to Yang bingbiao, who was lying on the assembly drawing looking for problems: "Lao Yang, please help me remove the clip on the manipulator and I'll get it later."

"Is the problem with the manipulator?" Situ Heyun was full of doubts when he heard Sun Lin's words.

This old bastard is too cheap.

You're talking to yourself.

However, I can't understand how to think about it. The design of this manipulator is made by imitating the imported CNC machine tool. The tolerance is smaller and the precision level is higher than that of the manipulator. There is no such problem with the imported bed. Why is there a problem in the test workshop?

Do not understand, situ Heyun can only temporarily put down his doubts and wait for Sun Lin to reveal the answer.

"Xiao Yun, go and persuade Lao sun. He's been up all night for two consecutive nights... Now let him go back to rest, and he doesn't do it. Not only that, but also forced Zhao bingbiao to sleep all night..." Yun Fei, who just walked around from all departments of the Office building, hasn't his ass next to the chair. Situ Heyun, with an anxious face, appeared in front of him.

"What?" Yunfei heard situ Heyun's words and immediately bounced forward.

"What's going on?" When Sun Lin said that it would only take three days, was he forced by himself? Even so, it shouldn't be. I didn't force him to come up with results at any time! Old man sun is in his 60s. He has 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 day before yesterday afternoon, he asked Zhao bingbiao and them to install the spare tool magazine. These two days, while staring at them for assembly and commissioning, he went to the production workshop to urge the workers to make some parts he wanted. If I hadn't just seen that he was in a wrong state, I asked him, where do I know, He was also in the office these two nights and didn't leave... "Situ Heyun walked quickly. As he walked, he told Yunfei what he had learned.

The whole 91 heavy industry, except Yun Fei, is estimated to never find anyone who can persuade sun Lin.

"Stop, stop!" As soon as he arrived at the area used for tool magazine test in the test workshop, Yun Fei saw several technicians talking to Sun Lin sitting on the chair. Sun Lin was shaking his head and urging Yang bingbiao, who was debugging, to hurry up from time to time.

"Mr. Yun, you're here. Please help us persuade the teacher..." seeing that Yun Fei came, the technicians around Sun Lin said anxiously to Yun Fei.

"Leave him alone and finish the debugging quickly. If it's wrong, we have to continue to improve..." Sun Lin didn't look at Yun Fei, so he yelled at Yang bingbiao who was going to stop.

"Mr. Sun, you'd better go and have a rest first. We're not in a hurry. Early or late, it doesn't matter... "Yun Fei doesn't know how to persuade an old engineer like sun Lin. If you want to give him a strong break, he doesn't work for himself. He doesn't understand what the old man has been stimulated by these two days. I just mentioned the cooperation with the capital. Is that so?

At the beginning, he was rejected by the first plane in the capital and lost face. But that's not the case, is it?

"It'll be ready soon. This time, there will be no problem! Xiao Yang, how long do you have? " Sun Lin didn't see Yunfei, and didn't know if he said that to Yunfei.

"Sun Lao, if you continue to do this, the boy can only be sorry. In the future, you'd better look back and provide for the elderly. If there is any accident in your old age, I can't afford this responsibility." When Yunfei heard Sun Lin's words, he was angry. He immediately broke down his face and said in a deep voice to sun Lin.

"Xiao Yun, don't blow me. Really, it will be better soon. This time, there will be no more problems. These two nights, I have been calculating that the reason why our tool magazine falls in the process of changing tools is not because of our design problems, but that the clip on the manipulator is 0.05mm short. The details determine the success or failure! "
