Smart 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 particularly important.What kind of process is arranged in the front and what kind of process is arranged in the back must go through strict and reasonable design.

Process engineers for complex high-precision and cutting-edge products must have rich processing experience in the workshop and also have rich theoretical experience.With rich theoretical experience and no practical operation experience, one cannot be qualified for the position of an excellent process engineer.

In Yunfei's world, Yunfei once heard a story, that is, a real thing happened in the aerospace system that the factory building is almost built, but the relocation has not yet started.In the late 90s, when those old engineers and technicians were about to retire, in order to improve their scientific research capabilities and processing capabilities, Aerospace Systems recruited a group of top doctoral students from key universities across the country.

Those top talents are the true pride of heaven, one or two are extremely powerful, and when it comes to theory, they are well-informed. Although they have not seen the new technology that appears abroad, they understand it very thoroughly.In particular, they believe that people like themselves, with what they have learned in books, are fully capable of technical work such as product design and process design.

As soon as several old engineers in charge of the technology retired, those doctors who thought they were far superior to those old engineers who graduated from technical schools or high schools strongly changed the technology that had been used for decades , implemented throughout the factory.

Of course, the implementation of the new technology needs the consent of the factory leaders before it can be implemented.The graduate students took out the theoretical knowledge they had learned all their lives, and several of them took turns to fight, making the leader stunned for a while.

Theoretically speaking, the products designed by the college students themselves, the production process designed by themselves.There will be no problems at all, especially their newly designed process can improve the efficiency by 15.00% compared with the previous production process, and the 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 process, everyone was dumbfounded.In theory there is no problem with the new process.During the final finishing process, it was discovered by those workers that they could not do what was theoretically possible.

Just one time, Yunfei's current neighbor lost hundreds of millions of yuan!Moreover, the intangible loss is far more than that.The batch of products at that time were military products exported to foreign countries. The originally stipulated delivery date was only discovered when the other party wanted to accept the products, and many products were still in the rough state!

that's all.The largest enterprise in the Economic and Technological Development Zone at that time began to decline, and finally in the early [-]th century, many affected factories went bankrupt, leaving only a few military production workshops.It was only when Yun Fei left that he slowly recovered.

"Why should the process arrangement be done on the grinding machine instead of on your lathe?" Yun Fei asked the lathe worker in his 40s with a gloomy face.

Originally in the inspection room, I saw the lathe worker quarrel with the manager of the quality department transferred back from the Pearl River Delta by the boss. The young female inspector who was originally from the 9327 factory knew that these old workers were uncles.If they are dissatisfied, their new boss will be beaten up at that time, and the matter will become a big mess.Under the eyes of their finished product inspection team leader, she went to the workshop director of the finishing workshop to rescue the scene.

"Director Fang, please hurry up, Mr. Chen just had an argument with Manager Cheng, what if the two start fighting..." The young female inspector walked quickly towards the finished product inspection room while turning her head to urge the same It was Fang Qiang, who was promoted from the workshop master, urging.

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

For him to be the workshop director, the rest of the people will not be convinced.

Especially guys on his level.

"Master Chen turned the finish machining that should have been processed by the grinding machine directly to size." Young Jian explained to Fang Qiang behind him while walking quickly.

The workshop director's office is not far 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 two ends of the workshop.

Hearing Young Jian's words, Fang Qiang understood what was going on.

He has worked in the workshop for decades, and he has a thorough understanding of the workers with good skills in their hands.Especially now that Jiuyi Heavy Industry's bonus 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 less allowance and more man-hours for lathe processing.Especially in batch processing, these divisional steps of processing, at the time of the final finish turning, as long as the car is aligned, 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 just outside the examination room, he heard Yun Fei's cold voice.

"Tell me, who arranged for you? Who arranged for the lathe worker to work on the grinding machine?" Yun Fei saw the 40-year-old lathe worker in front of him with a defiant expression and glanced to the side. The anger that had been suppressed in his heart had already On the brink of revenge.

The reason why Yunfei is so angry about workers not processing according to the process requirements is not that he does not believe in the skills of the workers, but that doing the final precision machining process on the lathe is too much a test of the skills and experience of the workers who operate the lathe.

On the z-direction (longitudinal) of the large pallet on the lathe, a small rotation is one millimeter; in the x-direction (horizontal) middle pallet, the tool tip moves 5 wires (0.05mm, such as 6132 machine tool, turn a small grid to move the tool tip to move 0.02mm), on the diameter processing, it is 0.1mm, because the workpiece on the lathe is rotating, the tool moves 1 mm, and the diameter of the part will be cut off by [-] mm.

Grinding machines are different. Grinding machines are precision processing equipment, and the level of machine tools alone is one level higher than that of lathes for ordinary processing.On the scale on the grinder, the feed is only 0.001 mm for each small division, that is, only one μ.

If workers want to process precision dimensions with a tolerance range of less than one thread on the lathe, they must use their own experience to divide a grid into ten equal parts or even one hundred equal parts for the final finishing process when entering the tool. Knives, as long as there is a slight deviation, it will cause the size of the parts to be out of tolerance.The grinding machine does not have this problem. The error range of a few μ is within the processing range of the equipment itself. As long as the tool is set before processing, as long as the measurement is accurate, there will be no problem at all by how much the difference is and how many grids are directly entered.

The biggest problem in grinding machine processing is that the wear of the grinding wheel causes the processing size to be too large, and it can be guaranteed by making up for the difference in time.

"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 do it?" Seeing Fang Qiang coming in, Yun Fei's suppressed anger finally burst out .

It would be a lie to say that he, the workshop director, doesn't know the process of the lathe grinding machine.

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

"Did you, the workshop director, arrange it for him, or did their team leader arrange it for him? During the weekly production meeting, the production department emphasized that the process must be strictly followed. This is how your precision machining workshop executes the process. ? A spindle plus materials plus labor cost hundreds of dollars, and it was scrapped in the last process, so what is the use of me as the workshop director?" Yun Fei didn't have any regrets about the lathe worker who caused this incident. Do too much care, but directly angry at their boss.

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

"Chen Dongsheng, didn't I tell you to strictly follow the process route?" Fang Qiang could only endure Yun Fei's anger. The factory had just started operation, and there were several quality accidents in his precision processing workshop. Otherwise, the young quality manager who is not even familiar with the site will not guard their precision processing workshop every day.

"I've done so much before, haven't there been any problems? Horses make mistakes, people make mistakes, who guarantees that they will never make mistakes in their work? I will pay attention next time, as for?" Chen Dongsheng heard Fang Forcibly questioning, I feel very uncomfortable.

I am no less skilled than Fang Qiang. In the end, he is just the monitor of a lathe worker's class, and Fang Qiang, who is not a few years older than himself, has actually become the workshop director. Not only does he not work, but his salary is more than half of his own.

"You did the same thing before?" Yun Fei gritted his teeth when he heard what Chen Dongsheng said.

Hearing Yun Fei's words and looking at Yun Fei's expression, Fang Qiang hurriedly gave Chen Dongsheng a wink to tell him not to talk nonsense.

"Yes, the grinder can't finish anyway, what's wrong with me helping out?" Chen Dongsheng ignored Fang Qiang's wink, and said to Yun Fei with his head raised.

This young man, Yun Fei, just got lucky and earned some money, and in front of his old master, he is just a paper tiger.Anyway, these workers are only workers of 9327 factory now, not workers of Yunfei Jiuyi Heavy Industry.Yun Fei, the boss, doesn't even have the right to dispose of himself.

"You mean that you helped, you scrapped the product, I still have to thank you, don't you?" Yun Fei smiled, he was pissed off. (to be continued..)
