For a Chinese New Year's Eve dinner, Yun Fei did not eat a bite of food, and began to be poured wine from the table.

When he got to the end, he didn't know how he got off the table, how many times he vomited, and he couldn't remember. In a daze, he was helped to his single dormitory, and slept in bed for two whole days before he could get out of bed weakly.

In the past two days, Luo Xiaoli has been serving tea and water before and after running every day. Yun Fei was afraid of delaying this secretary, who was not much older than himself, and resolutely refused the female secretary's courtesy, but Luo Xiaoli didn't care about Yun Fei's attitude at all, and still went her own way to cook and feed water.

The Chinese New Year is getting closer and closer, and there are many people in the factory who go home for the New Year, but the whole factory has not stopped production because of the New Year. The original two shifts have become a normal schedule because many people take leave to go home.

Although Yun Fei said that he was leaving, he did not leave now, and still occupied the position of deputy director of Qingfeng Machinery. Before and after the Chinese New Year, although there was a backlog of orders in the entire factory, Yun Fei did not force the workers who stayed in the factory and did not go home to work overtime.

The improvement of the organizational structure of the factory made him, the deputy factory director, idle, and even without him, there would be no chaos in the short-term production of the entire factory. Yun Fei, who was waiting for Ren Zhiguo's news, was too lazy to go around the workshop, and stayed in his office every day, thinking about adding a standard PMC shaft drive module to the three-axis machining center.

This is fairly simple in theory. But in practice, it's complicated. It not only involves electronic circuits, hydraulics and pneumatics, and the linkage of several different axes, but most importantly, it is necessary to design a single-chip microcomputer that can control at least four axes at the same time.

The so-called single-chip microcomputer is the integration of a computer system into a small piece of silicon wafer. In later generations, this thing was used in many places, such as mobile phones, telephones, calculators, home phones, and most other electronic products.

A microcontroller can also be described as a simple computer. However, the single-chip microcomputer used in CNC machine tools is not used on these small electrical products. In this era, CNC machine tools are used with special industrial control chips. Because the technology is far less developed than that of later generations, most of the CNC machine tools are connected in series with dozens or even hundreds of industrial control chips at the same time, so as to meet the control of various complex actions in the processing process of machine tools.

In this era of China, the research on single-chip microcomputer has just begun, and Yun Fei does not know where to find people who can develop industrial control chips that can control a large number of complex calculations at the time of the four-axis machining center. For microcontrollers, he only understands.

In his previous life, Yun Fei originally thought about studying microcontrollers when he was a graduate student, but later found that almost all the people who swept the streets were graduate students. In that era when it was better to study for a few more years than to mix for a few more years, Yun Fei entered the factory after graduation.

It is difficult to find a job, so he is an undergraduate student who follows those workers and masters to learn machine tool operation skills, starting from the simplest, a full ten years, before he mixes to the level of a senior technician. For Yun Fei's lack of business, as a technician, but following the workers to learn the operation of machine tools, not only the leaders have opinions on him, but the colleagues in the entire department are criticized.

Yun Fei didn't care about the ridicule and ridicule of his colleagues. At least, the income and status of an ordinary technician like him are far from being comparable to those skilled craftsmen in their hands.

In the factory where Yun Fei used to be, there were many masters in their thirties and forties, who were the most ordinary operators, but they received higher salaries than department managers. Every time there is a new product development, the department manager has to say good things to those experienced and skilled masters.

If anyone makes the master unhappy, he will directly drop the work in his hand: "If you have the ability, you come, Lao Tzu will stop doing it......" is that the boss of the company has to say good things and coax him.

Why is that? Isn't it because of the superb skills in your hands! The master will never worry about finding a job, and many small factories even support these masters. This is nothing else, just to be able to use his skills and experience to dry out the products when encountering high-precision and difficult machining parts.

As we all know, the higher the accuracy, the more difficult the parts to machine, the higher the processing cost, which means the greater the profit. Yun Fei had encountered this many times in a friend's mechanical processing factory.

Once, a friend of mine needed to use a complex special-shaped part on the equipment, and it was necessary to process eight holes on the surface, and each hole could not exceed 0.02mm error from each other. I found countless outsourcing processing factories, but others didn't dare to take over when they saw the drawings, and they refused even to ask the price. The most unfortunate friend had no choice, and found a retired old technician of the aerospace system through the relationship, and others just looked at the drawings for a while, and then quoted a processing fee of 20,000 yuan!

Some people say that it is necessary to use a machining center with more than five axes. The person who said this is definitely the one who doesn't know anything about machining centers. Because no matter what kind of high-end equipment you have, you need to clamp the parts when processing, and any high-end machine tool is impossible to complete the processing of such a special-shaped mechanical parts product that needs to be processed on each surface at one time.

As long as the machining cannot be completed at one clamping, the accuracy requirements of the position degree cannot be guaranteed.

Yun Fei was present at the time, and his heart was cold. This is simply Chiguoguo's blackmail! He thought, no matter what, the processing cost of a fist-sized parts can't be so outrageous! Unexpectedly, his friend happily agreed on the spot, and asked the master if 20,000 yuan was enough.

Yun Fei was stunned at that time.

When I got to the end, I saw that when the old master was working, his mouth was open enough to stuff an egg. The master spent three days and made a few small toolings, and the processing time, each of the eight surfaces is less than an hour, and the time of less than this hour, the time to really start the machine tool, will definitely not exceed five minutes! The rest of the time is spent on getting it right!

After the most Lu, Yun Fei asked the master, he did it in such a short time, why did he charge such a high price, isn't this obviously blackmail?

The old master told Yun Fei: "This is the price of skill and experience. ”

The friend of the most embarrassed Yun Fei told him that the master's words were not wrong, this was the price of skill and experience. If the part is not limited by the spatial dimensional accuracy of the eight faces, any senior technician can do it. The four-axis or five-axis machining center can only process six sides of the part at the same time, and the position degree of two faces and these well-machined surfaces is not easy to control.

After all, no matter how precise the CNC machining center, there will be processing errors. Machining errors are cumulative. The machine tool is not a person, and I don't know that the processing error will be automatically eliminated by the way.

Later, Yun Fei met a repairman who repaired the equipment that their company had bought back for tens of millions of dollars. Dozens of maintenance engineers in the entire factory worked for several days but did not find the reason, and finally had to find maintenance personnel through agents.

The repair cost 10,000 yuan. And all the repairman did was reconnect a tiny wire!

Yun Fei's boss was angry at the time: "You said that you just take such a line, can it be worth 10,000 yuan?" If our engineers do it, they won't be able to pay ten dollars! ”

The maintenance master laughed on the spot: "Indeed, it costs less than 10,000 yuan to connect this wire." My fee structure is like this - the cost of wiring is one dollar, and the cost of finding that wire is nine thousand nine hundred and ninety-nine dollars. ”

This is the technique of the arts; Again, it takes a lot of experience!

Because of these, Yun Feicai firmly believes that in order to become an excellent mechanical technician, it is necessary to be familiar with the operation of various equipment and master the performance of various machine tools. Only by understanding these can we be a good technician. Otherwise, I don't even know how to process, and I don't even know what equipment I need to use to process the products in my hands, and the task is arranged, and the operator directly throws a sentence: "I'm sorry, I really can't do this, the master didn't teach me back then, or you come to teach me how to use the lathe to get out of the octahedron without using the tooling on the lathe......"

Once Yun Fei met a superb colleague. That guy had just come out of school and was studying mechanical design, but he was in charge of the process in Yun Fei's factory, and directly found a miller and asked the miller to mill threads on the surface of an ordinary milling machine.

Seeing that the Chinese New Year was coming, Ren Zhiguo not only did not show up, but he didn't make a single call.

Yun Fei's heart became more and more anxious. He can count on the military behind Cammat to provide him with a group of various talents to develop the PMC shaft drive module attached to the three-axis machining center. Without the various experienced technicians and engineers in the hands of the military, how can he be alone, unless he has the superpowers in the online article, or carries a supercomputer from an alien civilization, how can he make a fourth axis involving countless specialties?

Tomorrow is February 2, 1992, that is, the twenty-ninth day of the lunar calendar, and the New Year will be on February 3rd.

Working in Qingfeng Machinery is not only because Yunfei does not have the original capital to start, but more importantly, this talent belongs to the era of national monopoly, and it is very difficult to open a technology-intensive and capital-intensive factory.

It was getting dark. Yun Fei smoked a cigarette in the office and pondered what he should do after the year. He couldn't stay in Qingfeng Machinery all the time waiting for an unknown result.

The original planned trip to the vast number of times had to be brought forward. They can't wait for their own August to come up with a low-end system that can't be lower-end, and if they do, what they are planning will be even more distant.

He didn't want to see the entire country's high-end machine tools printed in German or English twenty years after he came to the world.
