Chapter 33

Since Yun Fei arranged ye Beichun to the NC workshop, the whole person's body and mind began to rush to the independent product design and development of Qingfeng machinery. He spent little time in the NC workshop for two consecutive weeks. Even when he arrived, he just arranged things for Yang Guang and left. At most, he asked ye Beichun whether he could adapt to the environment.

Although pakchoi was very uncomfortable, he was extremely dissatisfied with the deputy factory director who had a good impression but was not familiar with him. In order to earn a high salary for an apprentice of 240 yuan a month, he had to silently follow Yang Guang to learn the operation of the processing center.

Although his grades at school were not top, they could not be considered poor. Ye Beichun learned a lot faster than other workers about the dozens of English buttons on the control panel of the machining center and some software in the PLC. However, only for the operation of the machine tool, the programming and the operation principle of the whole machine tool, Yang Guang felt that these apprentices did not need to understand, so he did not explain it.

Under the leadership of Yang Guang, several apprentices of the machining center who are highly expected by Yunfei are doing mechanical operation every day and learning the programming of the machining center with great difficulty.

Although the whole CNC workshop is very busy, there will be no lack of rest every Sunday.

Chen Jie is in love, so she disappears every Saturday night. Ye Beichun, who has just come to Qingfeng machinery, has no familiar people in this factory except Yun Fei. Originally, I expected Yunfei to play with me at the weekend. As a result, even the shadow of Yunfei could not be seen at the weekend.

Ye Beichun didn't have many friends in the whole factory except having a little communication with her roommates in swift garment factory. Especially after her sister ye Wuqiu went back to school, she became more lonely. Swift garment factory doesn't have weekends. It works for more than 12 hours every day. After work every day, it's tired like a dead dog. Sometimes it goes back to the dormitory and sleeps in bed without even washing.

At that time, ye Beichun didn't feel so terrible at the weekend.

When we arrived at Qingfeng machinery, on the first weekend off day, we only went back to the original swift garment factory and moved all our things back. We just fooled around outside. But by the second weekend, the feeling of loneliness was very obvious. Chen Jie went on a date with her boyfriend. She was the only one left in the dormitory of more than ten square meters. In this working age with few TV, no network and no entertainment, she could only open her eyes in the morning, look forward to dark and go to work the next day. It's not that she didn't want to go out to kill time. At this time, the industrial zone is far less prosperous than that of later generations. In order to save all the money to send home, ye Beichun can only stay alone in the dormitory, waiting for darkness, and then waiting for work the next day.

Ye Beichun was led to the workshop by Yun Fei. Under Zhang Rui's intentional or unintentional instruction, a few female workers in the whole factory kept a distance from her. Those single young people in the factory also dare not approach this beautiful girl who can be regarded as the flower of Qingfeng machinery factory because of the relationship between Yun and Fei. To be exact, because of the relationship between Yun and Fei, ye Beichun was isolated by most people of Qingfeng machinery.

Yunfei is also not welcomed by the young people of Qingfeng machinery factory, but he is using his spare time to copy the CNC system of later generations to the most critical place, so he has no feeling of loneliness or loneliness.

When ye Beichun stayed alone in the dormitory, he hoped that Yunfei, a boy he was not very familiar with, would appear in front of him. Unfortunately, Yunfei didn't appear at the first weekend. On the second weekend, Yunfei still didn't appear. He asked Yang Guang, director of the NC workshop. Yang Guang didn't know why Yunfei seldom came to the workshop during this time.

A workshop director has no right to manage what the deputy factory director does every day.

Although Qingfeng machinery has many CNC machine tools, these CNC equipment alone has exceeded 3 million. It can be seen that Wang Qingfeng attaches great importance to the NC machining industry. You know, the combined price of dozens of other ordinary metal cutting equipment in the whole factory is just over 2 million.

Especially not long ago, Qingfeng machinery purchased a brand-new fadal processing center through camart company, which cost more than 600000 yuan! In future generations, this model purchased by Qingfeng machinery is not enough, especially in foreign mechanical powers, this machining center is just the top CNC machine tool. In this era, the CNC machining industry in China is already a relatively high-end machine tool.

In addition to the first batch of people who studied CNC machine tools with Yunfei, most of the CNC workshops of Qingfeng machinery can not work independently. Those people are familiar with the programming and operation of CNC lathes and CNC milling machines.

Now Qingfeng machinery CNC workshop has begun to develop in the direction of cloud non expectation. Ordinary precision requirements and simple part structure drawings are programmed by skilled operators; The parts with high precision (within the tolerance range of 0.05mm) and complex structure (for example, there are several geometric tolerances, and the surface needs a lot of Boolean operations) are complicated by Yang Guang and Wu Zhongda. If they can't do it, of course, Yun Fei has to do it himself.

Yang Guang and Wu Zhongda have been to Qingfeng machinery for a long time. With Yun Fei, they have done a lot of high-precision complex machining parts. Now there are no big problems for these parts with particularly high requirements for process and tools. Both of them used to be senior technicians. The only deficiency is that they are not widely used in CNC machine tools and lack experience.

In the numerical control workshop of Qingfeng machinery, most people are apprentices. However, so far, ye Beichun, who was brought by Yun Fei, has only studied the processing center alone.

In this era of China, CNC machine tools are 100% imported. In addition to problems, we basically have to find old outsiders for maintenance. Not only are the accessories expensive, but the maintenance price is even more painful. If the apprentice accidentally bumped the knife and damaged the spindle because of his misoperation, it would cost at least tens of thousands of dollars!

Therefore, this processing center from the United States can be used by Yang Guang, Wu Zhongda and Yun Fei. Of course, after Yang Guang and Wu Zhongda of Yunfei church, he almost stopped doing this.

Machining centers, especially three-axis machining centers, can not be regarded as real machining centers in a strict sense. That is, a CNC milling machine with tool magazine. The real machining center must be more than four-axis linkage. It is estimated that the total price of the Chinese mainland in this era will not exceed ten sets. The price of one set will be at least more than the price of ten three-axis machining centers.

Whether there is a tool magazine and whether the tool change is automatic or manual is the only difference between a machining center and a CNC milling machine.

However, because of the automatic tool change function, the price of the machining center is almost two fifths higher than that of the ordinary NC milling machine. After all, many special-shaped workpieces or precision and complex parts with high requirements can not be guaranteed by manual tool change of NC milling machine.

Ye Beichun's job is to watch the automatic machine tool after Yang Guang has compiled the program, debugged and cut it. If the cutting tool breaks during processing, ye Beichun only needs to shoot the red "emergency stop" knob and ask Yang Guang to deal with it.

It has been 20 days since entering Qingfeng machinery. Ye Beichun has done nothing except pressing the green start button several times. No matter what parts Yang Guang does, he will tell ye Beichun in detail. Optical theory, no practical operation, ye Beichun is very depressed.

It's not that Yang Guang doesn't let ye Beichun learn, but that the price of this equipment is really too high! More than 600000 yuan. With Yang Guang's current salary of 251 months, he can afford to eat or drink for more than 20 years. So he didn't dare to let ye Beichun, who didn't understand anything, operate this sky high price machine tool. After all, he was careful and careful when he did it himself, for fear that he might make mistakes and damage the machine tool.

Ye Beichun watches the processing center every day at work, but he can only watch it boring. At the age of 16 or 17, how can we mechanically repeat such work every day and maintain passion? So she felt that she was fooled by Yunfei and cheated by Yunfei's hooligan. She wanted to find Yunfei to give herself an explanation.

The purpose of her coming to Qingfeng machinery is not only to need Qingfeng machinery, which is twice her original salary, but also to learn first-hand technology!

After staying in the NC workshop for so many days, I know that those NC lathe workers and NC milling workers apprentices can carry out some simple machine tool operations on the machine tool for more than 20 days, and there is no problem in setting at least some machine tool processing parameters and modifying the tool compensation.

But ye Beichun hasn't even personally operated the simplest knife installation and disassembly since this period of time; For the most simple basic operations of workpiece straightening, Zhao Zheng and tool setting, there is no.

Tomorrow is Sunday again. Qingfeng machinery doesn't work. So ye Beichun rushed to Yunfei's office after work. Although the relationship between the two was not so familiar, at least she received Qingfeng machinery from Yunfei, and Yunfei had to be responsible for her. It was precisely because of this idea that she summoned up the courage to find Yunfei and give herself an explanation when she was about to get bored.

Qingfeng machinery is gradually becoming formal, so every Saturday afternoon, before leaving work, all departments of the whole factory will gather together for a meeting to summarize and discuss various situations this week, so that Yunfei and factory director Wang Qingfeng can have a more detailed understanding of the situation of the factory.

At the weekend of the previous two weeks, because ye Beichun was not familiar with Qingfeng machinery, ye Beichun failed to find Yunfei several times after work, and there was no one in his dormitory.

Today, she waited for him directly in Yunfei's office.
