Smart Industrial Empire

"It's not your credit? Could it be that this bastard Yunfei really got the technology from abroad? He basically has nothing to do with foreigners. Where did he get these technologies?" Li Lu heard Sun Lin say this. Said, really surprised.

Could it be that he was really blinded by himself from the beginning?This is not right!If it was really a foreign technology, Yun Fei wouldn't be full of displeasure when he said this, and Ni Lishuang wouldn't be like a cat whose tail was stepped on.

"Could it be that those Soviet people made this?" Just like what Yun Fei said, Li Lu also has some doubts that these engineers from various industries who have never been in touch with numerical control will be able to work from scratch in just one year. A blank slate completes the production of samples from theoretical design to experimental improvement.If this is the case, people in the entire Soviet Union and China who have been engaged in CNC machine tools for a lifetime can go to see Grandpa Mao.

"How should I put it? As far as the two CNC milling machines you are looking at in front of you, the research direction and some necessary parameters were all designed by Yunfei. We and those Soviet engineers just designed his simple assembly. Refinement, many of them are the improvement plans he proposed..." Sun Lin said this, feeling a little embarrassed, and kept touching his nose with his hands.

"Him? How does he know the design of CNC machine tools?" Li Lu felt that she must have been deceived by the old man.The old man didn't know what good he got from accepting Yun Fei as a bastard, so he helped Yun Fei speak well and put gold on Yun Fei's face.

"Why can't he understand?" Hearing that Li Lu, a woman who looks like a rival in love but doesn't behave like one, looks down on her omnipotent brother Yunfei who wears underwear, Ni Lishuang is not happy.

Li Lu was full of doubts at this time, and she didn't want Ni Lishuang to quarrel at all. A young man who is less than 20 years old actually knows how to design CNC machine tools better than a member of the National Academy of Sciences who is nearly [-] years old and has been engaged in research on CNC machine tools for decades. ,How can this be?

"Gulu..." Li Lu wanted to ask Sun Lin what happened.The voice coming from her stomach reminded the others of the current time.

Entering the early summer, Rongcheng will not get dark until about eight o'clock at night. Although the outside is still extremely bright, the watch on the wrist clearly tells everyone that it is already past seven o'clock.

Li Lu still ate a little indiscriminately before boarding the plane. When she was in Rongcheng at noon, she was faced with a table full of dizzying dishes, because she was thinking about how to get Yunfei to give up the full power of agency in the entire Pearl River Delta. To Kamat, where's the appetite to eat?

"Boss..." Guderian saw Yun Fei greeting Sun Lin and the two beauties to go to dinner.I couldn't help being anxious, I just asked Yunfei, the boss, to see why during assembly, no matter what I did, the z-axis of these two CNC milling machines had several similar tapers. If this problem is not solved, these CNC machine tools During processing, the positioning accuracy will have at least an error of more than ten wires.

"Old Gu, why don't we wait until tomorrow to solve this matter? We are not in a hurry for this moment. We are assembling a CNC milling machine for the first time. The main thing is to accumulate experience and lay the foundation for mass production after the machine tool is finalized... ..." Yun Fei patted his head when he heard Guderian's words, for such a short time.He was so troubled by Li Lu that he forgot that it was Guderian who brought him to the CNC milling machine.

Li Lu only remembered at this time that the reason why she knew that Jiuyi Heavy Industry had already started the production of CNC milling machine prototypes was because the Soviet man came to him and the others to ask Yun Fei to help solve some problems...

"Xiaoyun, we can eat the meal later. You should help find a way to solve the problem first. If you solve the problem as soon as possible, your CNC milling machine can be launched to the market one day earlier..." Li Lu said to Yun Fei said.

It turned out that Guderian, a Soviet man, found Yu Yunfei and asked him to help solve the problem.She didn't pay much attention to it at all, nor did she think deeply about it.Now that Sun Lin, the old man he was familiar with, said this, Li Lu began to wonder, could it be that Yun Fei had asked someone to say hello before he came recently, and asked them to do this deliberately in front of her?Wanting to see what kind of miraculous abilities this kid Yun Fei has, especially looking forward to exposing the bastard Yun Fei's plot and making him feel ashamed, Li Lu now feels that it will be okay to have dinner later.

Seeing the sneer on Li Lu's face, Yun Fei couldn't help but get angry.

If the tiger doesn't show its power, you are really a sick cat!You have to be shocked, otherwise you really don't know the level of skilled workers in China!

At this moment, Yunfei himself was also hungry. After Ni Lishuang was discharged from the hospital, although the two of them did not live under the same roof, Ni Lishuang still gave Yunfei the habit of eating on time. He used to get off work at six o'clock every day. Every now and then, Ni Lishuang would appear outside Yunfei's office with a steaming meal.I have been used to a stomach that will be filled when I see it for several months in a row, and now I can no longer resist it like before and pass it.

Ni Lishuang never felt that going to work was more important than taking care of her elder brother Yunfei.No matter what Yun Fei said, she wouldn't listen to her, and would sneak away at 04:30 every afternoon to go home and cook.Regarding her behavior, no one in the whole factory dared to say anything, jokingly, if she offended the future proprietress, then she would stop working in Jiuyi Heavy Industry again.

For this matter, Yunfei actually mentioned Ni Lishuang once, but when Yunfei said it, Ni Lishuang immediately wiped his tears, and Yunfei could only acquiesce in the end.

"Brother Yunfei, I'll go to the cafeteria to see what's available for you first, and then I'll go back and cook?" Ni Lishuang knew that Yunfei must be hungry right now, although everyone didn't have lunch until four o'clock in the afternoon. The table dishes have not been touched.

"You don't need to go back to make it, you go to the cafeteria to see if there is anything ready-made, just get some..." Yun Fei said to Ni Lishuang.

Now when Ni Lishuang goes back to finish the meal, when he comes back, he will probably be hungry again.

People, it is easy to go from thrifty to extravagant, but difficult to go from extravagant to frugal!How long is this?My stomach can't even bear such a little hunger?Enduring the faint uncomfortable feeling in his stomach, Yun Fei walked towards the CNC milling machine where several workers were assembling the spindle.

"What's the problem?" Yun Fei turned around and asked Guderian after seeing that several people hadn't installed the main shaft.

He didn't intend to ask these questions to Sun Lin who volunteered to be an on-site dispatcher.In terms of design or other aspects, Sun Lin is a master and a master, and no one objected, but when it comes to assembling on site, maybe just find a seventh-level fitter, who understands better than Sun Lin, who is an academician many.

There is still a big difference between theory and practice.

"The main thing is the z-axis. When moving up and down, there will be a taper. No matter how we assemble or repair the guide rails, we can't eliminate the taper..." Hearing Yun Fei's question, Guderian was embarrassed answered.

This young boss has a fairly thorough understanding of these technologies.Among other things, many of the tooling that can improve assembly efficiency and ensure assembly accuracy are designed by this young boss.

"Remove the main shaft first, the problem in the moving process has not been solved, and it is useless for you to install the main shaft!" Now that you know the problem, you must find the cause of the problem.

The z-axis of the CNC milling machine mainly relies on the hydraulic system and the ball screw to connect the spindle head of hundreds of kilograms to the column. Fall under gravity.

Three fitters quickly hoisted out the precision spindle with dozens of steps above it that could reflect people's shadows.The two main shafts produced by Jiuyi Heavy Industry have spent a lot of time and energy. A total of five pieces have been invested, and there are only two finished products!

"You set up the dial indicator and let the z-axis move up and down, let me see..." Yun Fei said to three assembly fitters from the Soviet Union waiting at the side.

After the fitter set up the dial gauge on the workbench, Yun Fei ordered the worker to slowly move the entire spindle head up and down manually, while silently counting the rotation position of the pointer of the dial gauge.

"Grandpa Sun, what is he doing?" Li Lu was puzzled when she saw Yunfei staring intently at the thumb-sized watch. Could it be possible to solve the problems that these workers couldn't solve by just staring at it like this?

"This is to measure the perpendicularity between the main shaft and the worktable. At the beginning of the movement, the watch will set a position and move from top to bottom. If the watch does not move at all, it proves that there will be no movement during the entire movement. Errors occur. But this is only an ideal state. The first two test machines we designed, the main shaft moves up and down by [-] millimeters, as long as the verticality is guaranteed to be within [-], it is considered qualified..." Sun Lin turned towards Li Lu introduced the first test machine of Jiuyi Heavy Industry, and at the same time popularized the basic knowledge of machine tools to Li Lu.

Hearing Sun Lin's introduction, Li Lu couldn't help clicking her tongue.

The spindle head weighing several hundred kilograms moves up and down more than [-] millimeters, and the trajectory generated during the movement must be controlled within the range of one-sixth of a hair!

"Okay, there is no problem with the above assembly, why don't you use your brains? Since there is such a gap no matter how you assemble it, why don't you think of a way to clear the gap? Now the moving track of the spindle head is three wires to the left. Five, right? Put up one side of the column, tilt it to the right by [-], and then measure it..." Yun Fei found out the problem, and at the same time gave advice on how to deal with it.

Under Yun Fei's command, soon, the entire column of the machine tool tilted by three wires and fives. The tilt of something more than two meters high was less than half a strand of hair, which could not be seen by the naked eye at all. Dial gauge, where can it be measured? (To be continued..)
