Intelligent Industrial Empire

The technological process is not only related to the quality of the product, but also related to the processing efficiency of the product.

Especially for the processing of some complex products, the technological process is especially important.What kind of process is arranged in the front and what kind of process is arranged in the back must be strictly and rationally designed.

Process engineers for complex, high-precision and cutting-edge products must have rich processing experience in the workshop, as well as rich theoretical experience.With rich theoretical experience and no practical operating experience, it is simply impossible to be qualified for the position of an excellent process engineer.

In the world of Yunfei, Yunfei once heard a story, that is, a real thing happened to the aerospace system where the factory building is almost the same but the relocation has not yet begun.In the late 1990s, when the old engineers and technicians of the aerospace system were about to retire, in order to improve scientific research and processing capabilities, a group of top doctoral students from key universities were networked across the country.

Those top talents are the true favorites of the heavens, one of them is extremely powerful. When it comes to theory, the new crafts that have emerged abroad, although they haven't seen it with their own eyes, they also have a very thorough understanding.Especially they think that people like themselves, what they have learned in books, are fully capable of technical work such as product design and process design.

Several old engineers in charge of technology have just retired. Those who think they are far more powerful than those who are just technical schools or high school graduates have too many Ph.Ds. They have strongly changed the original technology that has been used for decades. , Implemented throughout the factory.

Of course, the implementation of the new technology requires the approval of the factory leaders to be implemented.The graduate students took out the theoretical knowledge that they had learned all their lives, and several people took turns in the battle, stunned the leaders.

Theoretically speaking, those college students’ self-designed products and self-designed production processes will not cause any problems at all, especially their newly designed processes can be 15% more efficient than previous production processes. , And quality control is also easier.However, in many companies, the implementation of new processes does not require the approval of leaders, because process engineers represent the highest technical level of a factory.

But I didn't expect that when most of the products were processed to the final stage, everyone would be dumbfounded.The new process that has no problem in theory is discovered by those workers in the final finishing process. What can be achieved in theory, they simply cannot do.

Just once, Yunfei’s current neighbors lost hundreds of millions of dollars!Moreover, the intangible loss is far more than that.The batch of products at that time were military products exported to foreign countries. The delivery date was originally stipulated, and when the other party had to check and accept the products, they discovered that many products were still in rough condition!

In this way, the largest enterprise in the Economic Development Zone at the time began to decline. At the end of the twentieth century, many affected factories went bankrupt, leaving only a few military production workshops in Yunfei. Only slowly recovered.

"Why should the process arrangement be finished on the grinder, and it will be done on your lathe?" Yun Fei asked the forty-something lathe worker with a gloomy face.

Originally in the inspection room, I saw that the lathe worker quarreled with the quality manager who was transferred back from the Pearl River Delta by the boss. It was originally the young female inspector who left behind at the 9327 factory. They knew that these old workers were all uncles. The new boss was beaten, and the matter was a big deal. Under the eyes of the leader of their finished product inspection team, she went to the workshop director of the finishing workshop to rescue the scene.

"Director Fang, please hurry up, Master Chen quarreled with Manager Cheng just now, in case the two quarrel..." The young female inspector quickly walked to the finished product inspection room, turning her head to urge the same. It was Fang Qiang, who was promoted from the workshop master, urged.

"Why are they arguing?" Fang Qiang, the workshop director, although he is very popular among the workers, he doesn't have much prestige.Originally, most of the skilled workers in the 9327 machining workshop have stayed. Although he is first-class in technology and extremely rich in experience, this is only one of the most skilled and experienced technicians in the entire workshop.

The rest of the people would not be convinced that he became the workshop director.

Especially those guys who are at his level.

"Master Chen directly turned the finishing that was supposed to be processed by the grinder to size." Young Inspection walked forward quickly while explaining to Fang Qiang behind him.

The office of the workshop director is not a small distance from the inspection room.You know, the entire workshop is hundreds of meters long, and the workshop director’s office and the finished product inspection room are just at the opposite ends of the workshop.

Fang Qiang understood what happened after hearing the young test.

He has been in the workshop for decades and has a thorough understanding of the workers who have good skills in their hands.Especially now the bonus for the entire Jiuyi Heavy Industry is constant based on output.

Although the lathe process has a large amount of processing and a lot of man-hours, the process of grinding machine processing has a small margin and high man-hours for lathe processing.Especially in batch processing, these sub-step processing procedures, in the final finishing turning, as long as the turning is right, the precision of the grinding machine can be achieved directly, even if the surface roughness cannot be compared with the grinding machine , As long as it is polished with sandpaper, it can also meet the requirements.

Fang Qiang quickened his pace, and he heard Yun Fei's cold voice as soon as he arrived outside the inspection room.

"Say, who arranged it for you? Who arranged the lathe worker to do the grinder process?" Yun Fei saw the forty-something-year-old lathe in front of him glancing his head to the side with a dull expression of anger. Already on the verge of revenge.

For workers who do not process according to the process requirements, the reason why Yunfei is so angry is not that he does not believe in the skills of the workers, but that he does the final precision processing procedures on the lathe, which is too test the skills and experience of the workers who operate the lathe.

For the large pallet in the Z direction (longitudinal) on the lathe, one millimeter is required to rotate a small grid; when the middle pallet in the X direction (horizontal) rotates one grid, the tool tip moves 5 threads (0.05mm, for small lathes such as 6132 machine tool, turning a small grid, the tip of the tool moves 0.02mm), in the diameter processing, it is 0.1mm, because the workpiece on the lathe is rotating, and the tool moves 1 mm, the diameter of the part will be cut off by two millimeters.

The grinder is different. The grinder is a precision processing equipment, and the level of the machine tool is one level higher than that of the ordinary processing lathe.For the scale on the surface of the grinder, the feed is only 0.001 mm, which is only one μ, for every small division.

If a worker wants to machine a precision dimension with a tolerance range of only a trace on the lathe, he must use his own experience to divide a grid into tens or even a hundred halves when entering the tool for final finishing. As long as the knife has a slight deviation, the size of the part will be out of tolerance.The grinder does not have this problem. The error range of a few μ, within the processing range of the equipment itself, before processing the tool, as long as the measurement is accurate, the difference between the time and the number of grids directly, there will be no problems at all.

The biggest problem with grinder processing is that the abrasion of the grinding wheel causes the processing size to be too large, and then it can be guaranteed to compensate for the difference.

"Fang Qiang, how did you become the workshop director? I asked you to be the workshop director and manage the entire factory site. That's how you are?" Seeing Fang Qiang coming in, Yun Fei's anger that had been suppressed finally broke out. .

It is a lie to say that the lathe worker is doing the work of the grinder.

"..." Fang Qiang's scolding at this powerful young boss was so depressed that he couldn't even speak.

"Did you, the workshop director, arrange it for him, or did their team leader arrange it for him? In the weekly production meeting, the production department emphasizes that the process must be strictly followed. This is how your precision machining workshop implements the process. A spindle plus materials and labor cost hundreds of dollars. The last process is scrapped. What use do I want you, the workshop director, to do?" Yun Fei didn’t have the lathe who caused this incident. Doing too much attention, but directly angry at their boss.

A workshop director, related to the production of the entire production workshop, is now the best embodiment.

"Chen Dongsheng, didn't I tell you to follow the process route strictly?" Fang Qiang could only endure Yunfei's anger. Not long after the factory started, his precision machining workshop and several quality accidents occurred. Otherwise, the young quality manager who is not even familiar with the site would not stay in their precision machining workshop every day.

“I’ve done so much before, didn’t there be no problems? Horses have blundered, people have blundered, who will guarantee that they will never make mistakes in their work? I will pay attention next time, as for?" Chen Dongsheng heard Fang Strong questioning is very uncomfortable in my heart.

He was not as technically inferior as Fang Qiang. In the end, he was no more than a squad leader of the lathes, and Fang Qiang, a guy who was not a few years older than himself, became a workshop director. Not only did he not work, his salary was more than half his own.

"What did you do before?" Yun Fei almost gritted his teeth and squeezed out these words when he heard the words of Chen Dongsheng.

Hearing what Yun Fei said, and looking at Yun Fei's expression, Fang Qiang hurriedly winked at Chen Dongsheng to tell him not to talk nonsense.

"Yes, the grinder can't finish it anyway, what's the matter with me helping me do something?" Chen Dongsheng ignored Fang Qiang's wink and said to Yun Fei, raising his head.

Yun Fei, this young man just made some money by taking some shit luck, and in front of his master, he is nothing more than a paper tiger.Anyway, these workers are only workers from the 9327 factory, not from Yunfei Jiuyi Heavy Industry.Yunfei, the boss, doesn't even have the right to deal with himself.

"You mean you helped, and you scrapped the product. I have to thank you, right?" Yun Fei smiled, he was angry.
