(come back, a few days' recommendation tickets, suck no force, brothers, over the chapter is over, what's wrong with it? Brothers, now the chrysanthemums of the villagers are broken. It's terrible... It's all right. Brothers, you can go to the list of new book signing list of new authors...)
A new year's Eve dinner, Yun Fei didn't eat a single dish and was filled with wine from the time he was on the table.
In the end, he didn't know how to get off the table. He threw up many times and didn't remember. Confused, he was helped to his single dormitory and slept in bed for two days before he got into bed.
These two days, every day Luo Xiaoli brought tea and water before and after running. Yunfei was afraid of delaying the Secretary, who was not much bigger than herself, and resolutely refused the female secretary's hospitality. However, Luo Xiaoli didn't care about Yunfei's attitude at all. She still went her own way to cook and feed water.
The new year is getting closer and closer. Many people go home for the new year in the factory, but the whole factory did not stop production because of the new year. The original two shifts have become normal work and rest time because many people ask for leave to go home.
Although Yun Fei said he would leave, he still holds the position of deputy director of Qingfeng machinery factory. Before and after the Chinese new year, although the whole factory had a backlog of orders, Yunfei did not force the workers who stayed in the factory and didn't go home to work overtime. After so much work for half a year, everyone took advantage of the Chinese new year to relax for a few days.
The improvement of the factory's organizational structure makes him the deputy factory director idle. Even without him, there will be no confusion in the short-term production of the whole factory. Yun Fei, who is waiting for Ren Zhiguo's news, is too lazy to wander around the workshop. He stays in his office every day, thinking about hanging a standard PMC shaft drive module on the three-axis machining center.
This is quite simple in theory. But in terms of practical operation, it is extremely complex. Not only involves electronic circuit, hydraulic and pneumatic, several non coaxial linkage, the most important thing is to design a single chip microcomputer that can control at least four axis linkage at the same time.
The so-called single chip microcomputer is to integrate a computer system into a small silicon chip. In future generations, this thing will be used in many places, such as mobile phones, telephones, calculators, home phones and most electronic products.
Single chip microcomputer can also be said to be a simple computer. However, the single chip microcomputer used in CNC machine tools can not be compared with those used in these small electrical products. In this era, CNC machine tools are all special industrial control chips. Because the technology is far less developed than that of later generations, most CNC machine tools use dozens or even hundreds of industrial control chips in series at the same time, so as to meet the control of various complex actions in the machining process.
In this era of China, the research on single chip microcomputer has just started. Yun Fei doesn't know where to find people who can develop industrial control chips that can control a large number of complex operations at the moment of four-axis machining center. For MCU, he only knows.
In his previous life, Yunfei had thought about studying single chip microcomputer when he was a graduate student. Later, he found that almost all the people sweeping the streets were graduate students. In an era when it was better to read a few more years than to mix a few more years, Yun Fei entered the factory after graduation.
It was hard to find a job, which made him an undergraduate. He followed those workers to learn machine tool operation technology. It took him ten years from the simplest to reach the level of a senior technician. For Yun Fei, who is not doing his job and is a technician, but follows the workers to learn machine tool operation, not only the leaders have opinions on him, but also the colleagues of the whole department have criticized him.
Yun Fei doesn't care about the ridicule of his colleagues. At least, the income and status of ordinary technicians like him are far from being compared with those skilled workers.
In Yunfei's former factory, many teachers in their 30s and 40s worked as the most ordinary operators, but received higher salaries than department managers. Every time there is a new product development, the Department Manager has to say good words and beg for those experienced and skilled teachers.
If anyone annoys the teacher and the teacher, he directly leaves his work: "if you have the ability, I'll quit..." the boss of the company has to say good words to coax him.
Why is this? Isn't it because of the exquisite skill in hand! Teachers will never worry about finding jobs. Many small factories even provide for these teachers. This is nothing else, just to be able to use his technology and experience to dry the products when encountering high-precision and difficult machining parts.
As we all know, the higher the precision, the more difficult it is to process the parts, the higher the processing cost, which means the greater the profit. Yun Fei once encountered such things many times in a friend's machining factory.
Once, a friend's factory equipment needed to use a complex special-shaped part, which needed to process holes on eight faces, and the error of each hole should not exceed 0.02mm. After looking for countless outsourcing processing factories, others dared not take over when they saw the drawings, and even refused without asking the price. Finally, my friend had no way. Through his relationship, he found a retired old technician of the aerospace system. Others just looked at the drawings for a while, and then quoted a processing fee of 20000 yuan!
Someone said, use a machining center with more than five axes. The person who says this is definitely someone who doesn't know about the machining center. Because no matter what kind of high-end equipment you have, you need to clamp the parts during processing. It is impossible for any high-end machine tool to clamp such a special-shaped mechanical part product that needs to be processed on each side at one time.
As long as the machining cannot be completed by clamping at one time, the accuracy requirements of position can not be guaranteed.
Yun Fei was present at that time, and his heart was cold. This is red fruit blackmail! He thought, no matter what, a fist big parts processing fee can't be so outrageous! But unexpectedly, his friend happily agreed on the spot and asked the teacher if 20000 yuan was enough.
Yun Fei was confused at that time.
Finally, when I saw the teacher working, his mouth was open enough to put an egg under it. The teacher spent three days and made several small tooling, and the processing time was less than an hour for each of the eight surfaces. In less than an hour, the time to really start the machine tool would never exceed five minutes! The rest of the time is used for alignment!
Finally, Yun Fei asked the old master why he charged such a high price after working in such a short time. Isn't it obviously blackmail?
The teacher Fu told Yun Fei, "this is the price of technology and experience."
Finally, Yunfei's friend told him that the old master was right. This is the price of technology and experience. If the part is not eight faces and has the limitation of spatial dimensional accuracy, any senior mechanic can do it. Four axis or five axis machining centers can only process at most six surfaces of the part at the same time, and the position of two surfaces with these machined surfaces is not easy to control.
After all, no matter how precise the CNC machining center is, there will be machining errors. Machining errors will accumulate. The machine tool is not human, and I don't know how to eliminate the machining errors automatically.
Later, Yunfei met a repairman who repaired the equipment his company bought for tens of millions of dollars. Dozens of maintenance engineers in the whole factory worked for several days and couldn't find the reason. Finally, they had to find maintenance personnel through agents.
The maintenance cost ten thousand yuan. What the repairman did was just reconnect a small wire!
Yunfei's boss was angry at that time: "you said you could connect such a line, which could be worth 10000 yuan? If our engineers come, we won't have ten dollars! "
The repairman smiled on the spot: "indeed, it won't cost 10000 yuan to connect this wire. My charging structure is like this - the cost of wiring is one yuan, and finding and connecting the wire is 9999 yuan. "
This is technology; This also requires rich and incomparable experience!
Because of these, Yunfei firmly believes that in order to become an excellent mechanical technician, we must be familiar with the operation of various equipment and master the performance of various machine tools. Only by understanding these can we be a better technician. Otherwise, I don't even know how to process, or even what equipment is needed to process the products in my hands. When the task is arranged, the operator directly threw a sentence: "I'm sorry, I really can't do this. The master didn't teach me in those years. Why don't you teach me how to produce octahedron without loading on the lathe..."
Once Yunfei met a top-notch colleague. That guy just came out of school and studied mechanical design, but he was in charge of technology in Yunfei's factory. He directly found a miller and asked the miller to mill threads on an ordinary milling machine.
Seeing the Chinese New Year coming, Ren Zhiguo not only didn't show up, but also didn't call one.
Yunfei's heart is becoming more and more anxious. He can count on the military behind camart to provide him with a group of various talents to develop the PMC axis drive module hung on the three-axis machining center. Without the various experienced technicians and engineers in the hands of the military, how can he get the fourth axis involving countless majors unless he has the super power in the online text or carries a supercomputer from an alien civilization?
Tomorrow will be February 2, 1992, that is, the 29th day of the twelfth lunar month, and the Chinese new year will be on February 3. Up to now, Ren Zhiguo still has no news. Yun Fei is a little cold hearted and starts to think about how to start without the military support behind camart.
Working in Qingfeng machinery is not only because Yunfei doesn't have the original capital to start, but more importantly, this talent belongs to the era of state monopoly. How difficult it is to open a technology intensive and capital intensive factory.
It's getting dark. Yunfei is smoking in the office, thinking about where he should go in the new year. He can't stay in Qingfeng machinery all the time waiting for an unknown result.
The planned trip to Guangshu must be advanced. They can't wait until August to come up with a low-end system that can no longer be low-end. In that case, the things in their plan will be even more distant.
He doesn't want to see the whole country's high-end machine tools printed in German or English 20 years after he came to the world.
