Siheyuan I can simplify skills

The machines at Beigang are also being debugged. Beigang is larger than the rolling mill, and its technical capabilities are much stronger.

Chief Engineer Li Zhiliang is a well-known figure in the industry.

Otherwise, the good thing about introducing imported equipment would not befall them.

However, at this time, they did not know the news that the Kyoto Steel Rolling Mill had successfully processed the latest workpieces for key units.

“We must get the processing task this time. Although the equipment we introduced is not the most advanced in the world, it is definitely the best in the country. Domestic machine tools are absolutely incomparable in terms of accuracy.” Li Zhiliang said.

Ding Kecheng, director of Beigang Factory, was a little worried:”I heard Director Ma from the Mechanical Department say that the steel rolling mill is developing new processing equipment, and they are likely to compete with us.”

“I’ve heard about the machine tools they designed. It was designed on the basis of the Da Mao machine tool when Da Mao assisted in construction. Even if the performance is improved, I estimate that the improvement will not be very large. You know, when Damao aided the construction at that time, what we were given were obsolete equipment from Damao at that time. Da Mao is always on guard against us.”Li Zhiliang said

“No matter what, we still need to debug the machine tool first. While foreign experts are here, we must master the use of these machine tools. Give full play to the superior performance of these advanced machine tools.”Ding Kecheng said.

Beigang also attaches great importance to this matter. The chief engineer, engineers, factory technicians, and senior fitters all participated in the debugging of the machine.

Under the guidance of foreign experts, the machine was quickly installed. Debugged and started processing. It showed very excellent processing capabilities.

Of course, the workpieces they used for trial processing were not difficult workpieces, but ordinary parts.

The performance of this batch of machine tools is indeed good, with high precision and stable processing. The performance is also very good. Compared with Da Mao’s machine tools, it is indeed much more advanced.

After the introduced machine tools were successfully put into operation, Beigang also held a grand celebration banquet.

Then it began to process the workpieces of key units.

But the results were not the same. Ideal.

The processing difficulty of these 21 batches of workpieces in key units is much more difficult than the workpieces they tried to process. Moreover, this batch of workpieces is confidential, and foreign experts cannot be used for guidance.

Beigang’s technical staff seem to have mastered the machine tools. Operation, but is still in the process of half-understanding. It is okay to process ordinary workpieces, but it is very difficult to process such high-precision parts.

The processing of several batches of workpieces has not been successful.

“Unqualified? what happened? Doesn’t it mean that you have mastered the use of machine tools? The processing accuracy range is also within the accuracy range of the machine tool, so how could the processing fail?”Ding Kecheng was furious when he heard the news.

He had just held a celebration banquet for the imported equipment that he had spent so much foreign exchange on, and he was slapped hard when he turned around.

Li Zhiliang frowned:”The accuracy of this batch of parts from the Academy of Sciences The requirements are very high.

The most important thing is that these parts are special-shaped workpieces, which are difficult to process.

The operators are not familiar enough with the machine tools, and it is difficult to adjust the fixture with 100% accuracy every time they change the processing surface.

This is the main reason for processing failure.

There is no problem with the accuracy of imported machine tools.

It’s a matter of use”

“If it doesn’t work, try a few more times! Even if it is a pile of materials, the operator must be able to master the use of the machine tool.”Ding Kecheng is still very determined.

Several specialized operators at Beigang also work consecutive shifts, and the machine tools never stop.

But the processed workpieces have problems here or there.

Engineer Wu Lianjun looked at them. The scrapped workpieces in the ground almost made me cry in anger.

“The accuracy of the machine tool is enough, why do problems always occur?”

Jia Duoyi, an eighth-level fitter, said:”During processing, the machine tool seems to shake from time to time. Then the surface being processed will fail in inspection. I think our operation is fine. The machine tool is unstable”

“impossible. This is a new machine tool. The machining accuracy we set is also within the accuracy range of the machine tool. It is not close to the critical value. Logically speaking, it can be processed.”Wu Lianjun said

“Otherwise, let’s try again. Jia Duoyi said.

When processing again, he found that the machine tool shook accidentally.

“It was shaking a bit just now. I think the processing of this noodle is stuck.”Jia Duoyi said.

Jia Duoyi marked the processing surface.

After the processing was completed, he conducted an inspection and found that there was indeed a problem with the processing of that surface.

Beigang found the problem, but Li Zhiliang was unable to solve it. And foreign experts After the celebration banquet, he had left. Now it would be very expensive to invite him back.

When Ding Kecheng explained the situation to Director Ma of the Mechanical Department, he got even worse news. The steel rolling mill had begun to They have provided the workpieces, so Director Ma told Ding Kecheng not to rush, to take his time and find out the problem. Even if he does not catch up with this batch of workpieces, he can still give them important workpieces for processing in the future.

Can there be no rush in this situation? Ding Kecheng almost died of panic. Am I worried that no one will process your workpieces?

The rolling mill used self-developed equipment to process the workpieces, while Beigang introduced expensive imported equipment, but the processing failed. I, Beigang Factory Director, this is going to end!

“This is impossible? Can a steel rolling mill have the technical capabilities to develop equipment with such high precision? Besides, the processing of this batch of workpieces is so difficult, how could they complete it?”Li Zhiliang couldn’t believe it.

“Everyone has already sent the processed workpieces to key units! What else is possible and impossible? Moreover, Director Ma said that the quality of this batch of workpieces is very high, and they are all top-quality products! But we can’t even process qualified products!”Ding Kecheng said.

Li Zhiliang frowned. This matter is troublesome. If it is not resolved in time, both he and Ding Kecheng will suffer.

This is a very heavy loss! Both of them will be imprisoned. Maybe.

Xu Yang was very surprised that the imported equipment from Beigang could not successfully process this batch of complex workpieces. After all, this batch of imported equipment from Beigang was originally introduced to process high-precision workpieces.

“This is a great thing for us. This batch of workpieces from key units all fell on us. Director Guo said with a smile.

“But the country lost a lot of money. The equipment that was imported at a large cost cannot be used, which is a huge loss.”Xu Yang said

“yes.”Director Guo sighed. It should be that Beigang has not mastered the use of machine tools yet.

Xu Yang did not think so:”It is also possible that someone else dug a hole for us deliberately. Not all foreigners are white doctors.”

Beigang has never been able to solve the problem of the machine tool. In the end, it had to ask the Qingda University Mechanical Department for help.

Director Ma and other experts were invited to consult on the imported equipment.

But they faced a problem. After the machine tool is disassembled, it no longer belongs to the manufacturer. The scope of repair. If you don’t disassemble the machine, you will not be able to master the maintenance technology of the machine tool. You will always be controlled by others in the future. More importantly, the introduction of this batch of advanced equipment is not just for processing high-precision machine tools, but to learn from foreign technology. Machine tool technology.

Professor Wei specially brought the student Xu Yang there.

“This opportunity is rare, so I called you here. Aren’t you designing a new generation of machine tools? Maybe imported equipment from abroad will be inspiring for your research.”Professor Wei finally secured a spot for Xu Yang. (To read Baoshuang novels, go to Feilu Novel Network!)

“Thank you, teacher.”Xu Yang was very touched. He didn’t get along with this tutor for a long time, but he really took good care of his cheap student. Beigang was very enthusiastic about the experts in the mechanical department. Factory director Ding Kecheng and chief engineer Li Zhiliang welcomed him in person

“Director Ding, let’s stop being polite. Let’s look at the machine tools first. This is what we came for. Director Ma said.

Ding Kecheng nodded:”Okay, I won’t be polite.” This time I was getting angry. The equipment imported at such a high price is not as good as the equipment developed by the steel rolling mill itself.”[]

Professor Wei smiled:”The engineer who developed that equipment happened to be here today.”

“ah?”Ding Kecheng was a little confused, why did the engineer from the steel rolling mill come here? Come to see our Beijing Steel joke.

“Xiao Xu is a graduate student in our mechanical department.

He was a student supervised by Professor Wei.

This was a rare opportunity, so Professor Wei applied to bring him here.

Although he is only an engineer, he is very capable in the field of machine tools.

The rolling mill’s machine tools have undergone two complete upgrades.

Technology upgrades have been made several times.

Each time, the accuracy improved significantly.

Especially the latest generation change has created a precedent for our domestic assembly line operations.

Director Ma said

“Boy, this is really awesome!”Li Zhiliang raised his thumb. Li Zhiliang asked himself that he couldn’t do it even if he developed a new machine tool. Even on the basis of Da Mao machine tools. China has also imitated Da Mao machine tools before, but let alone improving performance, it would be good if it could reach the level of Da Mao machine tools..

Xu Yang can continuously improve the accuracy of machine tools. This is really amazing.

“Xiao Xu, we have to work hard this time to help us find the problem.”Ding Kecheng said politely.

He didn’t think Xu Yang could solve Beigang’s technical problems, but Xu Yang was young. And he was so valued by Director Ma. It was obviously not easy. If he couldn’t help this time, it didn’t mean that he would be able to solve it in the future. I can’t help you. Such a talented person cannot stay in a small steel rolling mill.

“I’m here to learn this time.”Xu Yang said.

When we arrived at the workshop, the imported machine tools had stopped.

“Everything was actually normal during processing, and there were no problems with our operations. However, every time during processing, the machine tool will occasionally vibrate abnormally. resulting in processing failure.”Wu Lianjun said

“Could there be a problem with the servo motor inside?”Professor Wei said

“Probably not. This is brand new equipment. This phenomenon did not occur when we processed ordinary equipment. This problem will arise once high-precision parts are processed.”Wu Lianjun replied

“What is the problem? The only way is to take it apart and take a look! Director Ma said

“dismantle!”Ding Kecheng said.

Beigang has asked its superiors for instructions on this issue and received approval. Anyway, if you want to learn advanced machine tool technology, you have to disassemble it and see the structure inside.

Even if you cannot learn the technology, you must master the maintenance technology yourself. Otherwise, you have to master the maintenance technology yourself. Every time a problem occurs, the manufacturer is asked to repair it, and Beigang cannot afford the cost.

Xu Yang feels that there is something wrong with the fixture master of the machine tool. There is no problem with adding ordinary parts to the fixture, but the shapes of these special-shaped workpieces in key units are not Rules. If there is a slight deviation in the fixing process, jitter will naturally occur during the processing.

Of course, Xu Yang cannot be completely sure, because during Beigang’s processing, the problem does not lie on the same processing surface.

What’s more , Xu Yang also wanted to see the internal design of the machine. How could such a good learning opportunity be wasted? Even if the problem was determined, he had to wait until he had finished studying. The machine tool was disassembled, and the structure inside It is indeed much more complex and precise than Da Mao’s machine tools.

But complexity is actually not a good thing. It is definitely more difficult to maintain. It is definitely not as rough-resistant as Da Mao’s machine tools.

The structure inside is something Xu Yang cannot see from the data. Xu Yang is here The machine tools seen in the Mechanical Department’s data room are often obsolete designs. Even this machine tool is still far behind the world’s most advanced level.

Everyone looked serious.

This was everyone’s first time Seeing the internal structure of this precision imported equipment, it would take a lot of time to fully understand the technology of this machine tool, let alone find the faults inside.

The machine tool was slowly disassembled, and every step was Take photos first to ensure that there will be no problems with the subsequent installation.

Xu Yang remembers Superman at a glance, and can remember all the structures inside. After all, Xu Yang has independently designed many sets of equipment. Although the cores are all It is the structure of Da Mao machine tool. But these internal structures are basically universal.

Although this machine tool is more advanced than Da Mao machine tool, many transmission devices are similar in principle, so Xu Yang can still understand it.

After dismantling the machine tool , and tested each component. No problem was found.

It was previously suspected that there was a problem with the servo motor, but during the test, the servo motor seemed to be normal.

“Reinstall it and process it. Find out what went wrong.”Director Ma said.

Everyone started to install the machine tool again. This time it was much slower than the disassembly. We had to constantly compare the photos to ensure that there were no problems during the installation process.

During the disassembly, the parameters of each part had been measured. Looking back You can draw the architecture and even copy it. Of course, it is hard to say whether the accuracy can reach this level.

After reinstallation, start the test. But the problem still exists. If the problem cannot be found, these experts I have a headache.

Even if someone else really tampered with the machine tool and you can’t find it, it’s still in vain…
