This is also the only laboratory building of the military sub-district that is not located in the scientific research area, but is placed in the headquarters of the military sub-district that is heavily guarded.

The whole building is six floors above ground and three floors underground.

The third to sixth floors are mechanical, electronic, chemical and biological laboratories. The first and second floors are opened, with an area of 1,600 square meters and a height of 7 meters, equipped with various self-made assembly equipment such as automatic cranes, arc welding equipment, and small electric vehicles, and is a well-equipped assembly workshop.

The first and second basement floors are placed with large, medium and small, as well as marble pedestal micro automatic machine tools, supplemented by a variety of advanced automatic measuring instruments, which can carry out CNC machining with extremely high precision.

The third basement floor is the power distribution center for the entire laboratory building, and the power is distributed to the laboratory through three independent wires to ensure that there will be no power outages due to line problems. At the same time, as a backup power source in an emergency, a set of 2,000 kilowatts of heavy oil generator sets and oil reserves are also prepared to serve as a backup power supply when the three lines are interrupted at the same time.

At the same time, each laboratory is equipped with a large 600-watt uninterruptible power supply to support a sudden power outage and the basement backup engine is not yet started.

The entire laboratory building is tightly guarded and the equipment is advanced, which is unparalleled in the military sub-district and surpasses any scientific research institution in China. Even compared with foreign laboratories, it is not necessarily worse, and some parts may be better.

The owner of this experimental building is naturally the supreme head of the military sub-district -- Guan Fei!

A large part of the reason for the continuous improvement of Xincheng's scientific research ability and precision manufacturing level is the credit of scientific research and technical personnel and outstanding technicians from China, which of course has many benefits for speeding up the manufacturing industry of military sub-districts. But at the same time, if he wants to privately engage in some research and manufacturing beyond the background of the times, it is difficult to hide the attention of those who have a heart.

Guan Fei doesn't care much about learning skills from military divisions in China, but he doesn't want to have no hole cards in his hand.

In the future, he will gradually carry out secret research and development of certain technologies, which will be an important guarantee for the survival of military divisions. If we can keep it secret for a longer period of time, we will be able to win more time for the military sub-region to grow.

So he carved out a small valley in the deepest part of the camp and built such an experimental building.

There are more than 6,800 soldiers and elite guard battalions to protect them, not to mention outsiders, even Zhang Shengguo and others are not allowed to enter if they are not invited.

The 124 researchers and 63 outstanding technicians in the laboratory building are all carefully selected by his repeated observation over the years, and they are either extremely obsessed with technology and scientific research maniacs, or loyal and reliable followers. They usually live in dormitories next to the experimental building, and their living conditions are much higher than those of other cadres and masses in military sub-districts, except for restrictions on going out.

Guan Fei's bio-sidebrain personality recognition program is not a panacea, and it cannot guarantee that these people are 100% loyal. But with their accurate analysis, at least in the absence of sufficient opportunities, they can keep secrets and will not easily leak them to the outside world.

At least for now.

Moreover, a person's change must be a long-term process, and there will definitely be various external manifestations, and the person who can perfectly hide the change in his heart can only be a trained spy elite. Even 007 will leave all kinds of clues when doing things, and it is impossible to hide it from Guan Fei's eyes.

……

Zou Yongdong stood in front of a vertical CNC machining center, staring at the workpiece moving forward and backward, rotating left and right under the control of the operating arm, looking obsessed.

He has watched such a scene more than a hundred times, but he is still deeply fascinated.

The power of industry is concentrated in it.

He never imagined that he who used to think that he could only be a big soldier would come to this height. At the beginning, because he passed the examination, he became the first batch of troops to be selected to enter the technical school to learn machine tool operation, and then due to slow progress, he was thrown by the master to learn the CNC lathe that had just been established. Who knows, but it is just the right way, relying on excellent memory, soon emerged in the operation of CNC machine tools, and became the leading CNC machine tool technician in the factory after entering the precision machinery factory.

Probably because there were too many setbacks in the first 20 years, no matter how ups and downs his life was, whether he was a soldier, learned skills, or was disliked by his master, or later became the honorific title of "Master Zou" and "Zou Technician" in the mouth of others, Zou Yongdong was not spoiled, he still did his job, honestly did his own thing, did not be proud, not complacent, not opportunistic, and did not work hard.

Compared with his senior brother Kong Lingchen, who is now an alternate deputy to the National People's Congress, he is like an unknown stone, without a glamorous appearance, and always sticks to his duty. When Kong Lingchen actively joined the party, he did nothing, but still silently operated his CNC lathes and completed the production of high-precision parts and components urgently needed in one factory after another.

As a result, Kong Lingchen tried several times, but was turned away. He, an ordinary technician who had never said a word of grandeur, was asked by the factory party committee to talk many times, mobilized repeatedly, and talked about the vanguard, responsibility, and leading role, and tried every means to crown him with the title of party member.

Before he could hear a few sour words from his senior brother, he was approached again and asked if he would like to go to a secret department to contribute to the development and growth of the military subdivision.

It is said that it has developed and grown for the military division, and Zou Yongdong naturally has no choice but to say anything, so he honestly said that he was willing.

Then he was screened several times, and he was personally interviewed twice by Guan Fei, the supreme head of the military sub-district, and his name was completely crossed off the list of workers in the precision machinery factory where he had worked for two years, and he came to this heavily guarded place.

The management system here is very strict, and everyone can only do their own thing. If you shouldn't ask questions, you must not ask them, otherwise you will be removed immediately. If you ask for top-secret information, you will be sentenced or even shot if you don't get it right!

Zou Yongdong didn't dare to violate discipline, and he didn't have much interest in knowing other people's affairs.

For him, it is his duty to conscientiously do his job well and complete the tasks assigned by his superiors.

When Zou Yongdong first came, the laboratory building was not what it is now, CNC machine tools or something, all of which were equipment used in the precision machinery factory.

The five-axis linkage CNC machining center in front of him is all made by themselves in the past year or so, under the guidance of the commander, and they have made it by themselves, a steel scrap and a steel scrap!

Of course, all the design drawings, tooling drawings, and parts drawings were all provided by the commander, and they just processed them. Some parts that require extremely high precision can only be made by the commander himself. When it comes to assembly, the commander does it, and they can only work on the side, helping to hand over parts, tools, etc., but they can't help much.

Not to mention that these technicians can't help much, but the same is true of those technicians.

The control circuit was designed by the commander, the components were provided by the military division, the chips were purchased from abroad, and in the end, even the program was entered by the commander character by character. They also help to solder a component and check whether there are any soldering errors or damaged components.

Speaking of which, this batch of equipment is the top and most sophisticated processing equipment that Zou Yongdong has ever seen.

For example, the alloy materials used in various precision parts are provided by the military division, and in order to meet the different physical requirements of different parts, dozens of furnaces of steel have been smelted according to different formulas! The parts made of this batch of new materials have far more wear resistance, impact resistance, stiffness and strength than before, and their service life is several times that of before.

For example, in order to ensure the deviation during machining, the tools used are also specially made, and the error caused by tool change and tool wear during long-term machining is reduced to a rare accuracy of 0.006 microns.

For example, in order to ensure the error caused by the movement of various mechanical parts, a large number of optical and laser measuring equipment are used. Although these instruments are very cumbersome, but the role is really not small, their detection accuracy is as high as one thousandth of a micron, and then through error compensation, by the high-precision servo motor imported from Japan for precise control, so as to improve the workpiece, tool positioning accuracy to five thousandths.

Not to mention all kinds of other transformations, even the coolant during processing is specially configured, which not only improves the machining accuracy, reduces the wear of tool and abrasive, but also plays a role in rust prevention, mildew prevention, cleaning the workpiece, and does not hurt the skin - although the previous coolant is also effective, but it hurts the skin, because of long-term contact, the stratum corneum on the surface of Zou Yongdong's palm is seriously damaged, and it looks very old.

After the military sub-district made every effort to build and took more than a year, it finally came up with this batch of top processing equipment.

As far as investment is concerned, even if the military sub-district is not short of money, to be honest, it does not have the financial resources to comprehensively upgrade all factories according to this standard.

If all the investment is counted as money -- although some of the core components can only be completed by the commander's hands, and even money cannot buy them in the outside world -- the five-axis linkage numerical control center in front of you, which is three meters high and five meters wide, is worth no less than millions of yuan, and maybe it is even more expensive......

But you get what you pay for, and that's true.

The machining capacity of this machining center is really amazing, a forged workpiece is put on, and in less than an hour, an engine cylinder that is sparkling and smooth even if it is no longer polished is manufactured!

With the complexity of this cylinder, if the previous manufacturing method is still used, Zou Yongdong roughly estimates that it will take at least forty hours or more!

That's the power of technology!

Although Zou Yongdong has been processed hundreds of times on this five-axis linkage CNC center, he has been moved by this great power every time with the same input.

A trace of alloy shavings fell from the cylinder, and milky white coolant flowed down from above, cleaning the workpiece.

The finishing tool completes the last process, slowly retracts and resets under program control, and the clamped cylinder slowly stops moving.

Ding, a clear sound, the red indicator light in the CNC center is being processed, and the green light next to it lights up, indicating that the operation has been stopped and the workpiece can be removed.

The locked inner buckle is also automatically retracted, and the imported explosion-proof glass door gently pops open a crack.

Zou Yongdong sighed slightly.

This set of CNC center is easy to use, but unfortunately because it is a five-axis linkage, the parameters involved are too many and too complex, and the programming difficulty is extremely high. And the specific programming method commander did not give them it, it is said that this is only a primary version of the use of imported chips, and soon the military division will change the self-made processor, or the Chinese use environment, in order not to let them bother with the control system that is about to be eliminated, so they will not teach them how to CNC programming.

This also makes Zou Yongdong and them can only follow the set procedures to monitor the operation of the equipment and deal with emergencies, and at other times they just move the workpiece up and down, acting as an ordinary worker.

Seeing such advanced equipment, but not being able to fully grasp and use it freely, it is the biggest torture for them and technicians.

There is no way, only hope that the self-made Chinese processor of the military subdivision can be developed as soon as possible.

"Is it processed? What happened to the other parts? Zou Yongdong was about to take out the machined cylinder, when he heard a familiar voice behind him, and he replied reflexively, "Well, including this, ten cylinder blocks have been completed." The parts of the crankshaft and the gears have also been completed, and the final grinding and polishing process is underway; The cylinder head and pipes have been made in the morning and are being assembled ......"

As he spoke, he suddenly realized who the person was asking, and hurriedly and carefully placed the cylinder, turned around and smiled embarrassedly: "Commander, I didn't know it was you......"

"It's okay, it's okay, when I came, I saw that you were very dedicated to your work, so I didn't bother you." Guan Fei smiled, he had a very good impression of this serious young man, and his score of the biological deputy brain was also among the top twenty, and he was a good seedling worth vigorously cultivating, so he waved his hand and asked him not to be restrained, and turned the topic aside, "Then this batch of workpieces is finally processed, wait to complete the honing, carry out the final cleaning process, and we will be able to assemble it tomorrow." ”

Honing is to use oil stone to finely polish the cylinder running pipeline, and the grinding accuracy is higher than the machining accuracy. The domestic machining accuracy has not been able to go up, and many precision parts are improved to the aerospace level by relying on fine grinding.

A small amount of boron nitride stone developed by the military sub-district laboratory can improve the polishing accuracy to an ultra-high precision of 2 thousandths of a micron, which is not inferior to the highest level abroad.

Guan Fei watched Zou Yongdong send the cylinder to honing with a trolley, and smiled with satisfaction.

This smile is not only satisfied with the fast processing speed, which can be used in the final assembly immediately, but also a commendation for the skilled workers such as Zou Yongdong.

When they grow up, the military division's tomorrow will change greatly!
