This is an experimental building.

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

The building is six floors high above the ground and three floors underground.

The three to sixth floors are mechanical, electronic, chemistry, and biology laboratories. The first and second floors are opened, with an area of ​​1,600 square meters and a height of 7 meters. They are equipped with various self-made assembly equipment in military sub-districts, such as automatic cranes, arc welding equipment, small electric vehicles, etc. It is a fully equipped assembly workshop.

The first and second floors underground are placed with large, medium, small, and marble pedestal miniature automatic machine tools, and are supplemented by various advanced automated measuring instruments, which can perform CNC machining with extremely high accuracy.

The third floor underground is the distribution center of the entire experimental building. The laboratories are distributed through three independent wires to ensure that there will be no power outage due to line problems. At the same time, as a backup power supply for emergency moments, a 2,000-kilowatt heavy oil generator set and oil reserve are also prepared to serve as backup power supply when three lines are interrupted at the same time.

At the same time, each laboratory is equipped with a large 600-watt uninterruptible power supply, which is a support for the basement backup engine before it is started.

The entire experimental building is so tightly protected and advanced that it is in the military sub-district, and it is even better than any scientific research institution in China. Even compared with foreign laboratories, it may not be worse, and some parts may be better.

The owner of this experimental building is naturally Guan Fei, the highest leader of the military sub-district!

Xincheng's scientific research capabilities and precision manufacturing level are constantly improving, a large part of the reason is the contribution of scientific research and technical personnel and excellent technicians from China. This is of course beneficial to accelerating the manufacturing industry of the military sub-district. But at the same time, if he wants to do some research and manufacturing that goes beyond the background of the times in private, it is difficult to hide the attention of those who are interested.

Guan Fei didn't care much about learning skills from the military sub-district in China, but he didn't want to have no trump cards in his hand.

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

So he drew a small valley at the deepest part of the camp and built such an experimental building.

More than 6,800 soldiers and elite guard battalions were protected. Not to mention outsiders, even Zhang Shengguo and others could not enter if they were not invited.

The 124 researchers and 63 outstanding technicians in the experimental building were all of whom he repeatedly observed and carefully selected over the years. They were either scientific research madmen who were extremely obsessed with technology or loyal and reliable followers. They usually live in the dormitory next to the experimental building. In addition to being restricted from going out, their living conditions in all aspects are much higher than other cadres and masses in the military sub-district.

Guan Fei's biological sub-brain personality recognition program is not omnipotent, and it cannot guarantee that these people are 100% loyal. However, with his precise analysis, at least in the absence of sufficient opportunities, they can keep secrets and will not easily leak them.

At least for now.

Moreover, a person's change must be a long-term process, and there will definitely be various external manifestations. People who can perfectly hide changes in their minds may only be trained intelligence elites. Even in 007, they will leave all kinds of clues when doing things, and it is impossible to hide them from Guan Fei's eyes.

...

Zou Yongdong stood in front of a vertical CNC machining center, staring at the workpiece without blinking, moving forward and backward under the control of the operating arm, rotating left and right, and looking obsessed.

He had watched such a scene more than a hundred times, but he was still deeply fascinated by it.

The power of industry is condensed into it.

He never thought that he, who had thought that he could only be a big-headed soldier, would reach the height he is today. He was the first group of troops to be selected to enter the technical school to study machine tool operation, and then due to slow progress, he was thrown to learn the newly established CNC lathe. Unexpectedly, he happened to be right away. With his outstanding memory, he quickly made his mark in CNC machine tool operation. After entering the precision machinery factory, he became the leading CNC machine tool technician in the factory.

Probably because he suffered too many setbacks in the first twenty years. No matter how ups and downs of life, whether he was a soldier or learned technology, he was disliked by his master, or later became the "Master Zou" and "Technician Zou" as respected by others. Zou Yongdong was not favored or disgraced, and was still responsible for his own work, and did his own things honestly, not proud, not complacent, not opportunistic, and not working hard.

Compared with his senior brother Kong Lingchen, who is now the alternate NPC representative, 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 and silently operated his CNC lathes and completed the production of high-precision parts 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 bold word, was asked by the factory party committee to talk many times, and repeatedly mobilized, saying that he was a vanguard, and he was responsible and leading. He tried every means to give him the title of party member.

Before he could hear his senior brother say a few sour words, he was asked again and asked if he would like to go to a confidentiality department to do his part to develop and grow the military sub-district.

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

Then he screened several times and was interviewed twice by Guan Fei, the highest leader of the military sub-district, and his name was completely removed from the list of workers in the precision machinery factory who had worked for two years and came to this heavily guarded place.

The management system here is very strict, and everyone can only do their own things. For those who should not be asked, you must not ask, otherwise you will be removed from the list immediately. If you are asking for top-secret information, you will be sentenced or even shot!

Zou Yongdong dared not violate discipline and did not have much interest in knowing about other people's affairs.

For him, doing his own work seriously and completing the tasks assigned by his superiors is his duty.

When Zou Yongdong first came, the experimental building was not the ones that were placed in the present, CNC machine tools, etc., were all equipment that he used to using in precision machinery factories.

The five-axis linked CNC machining center in front of him was all made by them in person under the guidance of the commander over the past year!

Of course, all the design drawings, tool drawings, and component drawings are provided by the commander, and they only process them according to the processing. The commander can only make some parts with extremely high accuracy requirements. When assembling, the commander takes action. They can only help with the help of handing over parts, tools, etc.

Don’t say that these technicians can’t help much, the same is true for those technicians.

The control circuit was designed by the commander, the components were provided by the military sub-district, the chip was purchased from abroad, and the program was entered by the commander by one character. They also helped to weld a component and check whether there were any welding errors and components were damaged.

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

For example, the alloy materials used in various precision parts are provided by the Military Sub-district. In order to meet the different physical requirements of different parts, dozens of furnaces of steel were specially smelted according to different formulas! The components made of this batch of new materials have abrasion resistance, impact resistance, stiffness and strength far exceeding the previous one, and their service life is several times that of the previous one.

For example, in order to ensure the deviation during processing, the tools used are also specially made. The error caused by tool wear during tool change and long-term processing is reduced to a rare accuracy of 006 microns.

For example, in order to ensure the error caused by the movement of various mechanical components, many optical and laser measuring equipment are used in large quantities. Although these instruments are very bulky, their effect is really not small. Their detection accuracy is as high as one thousandth of a micron. Then, through error compensation, it is precisely controlled by a high-precision servo motor imported from Japan, thereby increasing the positioning accuracy of the workpiece and tool to five thousandths.

Not to mention various other modifications, even the coolant during processing is specially configured, which not only improves the processing accuracy, reduces the wear of tool abrasives, but also prevents rust and mildew, cleans the workpiece, and does not damage the skin. Although the previous coolant has a good effect, it hurts the skin. Due to long-term contact, the cuticle layer on the surface of Zou Yongdong's palm is seriously damaged and looks very old.

After the military sub-district was fully built, it took more than a year to finally create this batch of top-level processing equipment.

In terms of investment, even if the military sub-district is not short of money, to be honest, there is no financial resources to comprehensively upgrade all factories according to this standard.

If all investments are counted as money - although some of the core components can only be completed by the commander's actions, they can't even buy them even if they have money - the three-meter-high and five-meter-wide five-axis linked CNC center in front of me is worth no less than millions of yuan, and maybe even more expensive...

But you get what you pay for, that's right.

The machining capability of this machining center is really amazing. When a forged workpiece is placed on it, it is less than an hour. Even if it is no longer polished, it is still shining and has an extremely smooth engine cylinder with an extremely smooth surface.

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

This is the power of technology!

Although Zou Yongdong has been processing this five-axis linked CNC center hundreds of times, he has the same investment every time and is moved by this great power.

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

The finishing tool completed the last process, slowly retreated and reset under program control, and the clamped cylinder slowly stopped moving.

Ding, with a clear sound, the red indicator light that was being processed in the CNC center went out, and the green light next to it illuminated, indicating that it had stopped operating and the workpiece can be removed.

The locked inner buckle also retracts automatically, and the imported explosion-proof glass door gently flicks open a slot.

Zou Yongdong sighed slightly.

This CNC center is easy to use, but unfortunately, because it is a five-axis linkage, the parameters involved are too many and complicated, and the programming is extremely difficult. Moreover, the commander did not hand over the specific programming method to them. It is said that this is just a primary version of imported chips, and it will soon be replaced with the homemade processor of the military partition, and it is still in the Chinese usage environment. In order not to make them worry and work hard on the control system that is about to be eliminated, I will not teach them how to program CNC.

This also made Zou Yongdong and his team able to monitor the operation of the equipment and deal with emergency situations according to the set procedures. At other times, they just moved the workpieces up and down and acted as an ordinary worker.

Seeing such advanced equipment, I cannot fully master it and use it freely, it is the greatest torture for these technicians.

There is no way, I can only hope that the Chinese processor made by the military sub-district can be developed as soon as possible.

"Have you finished processing? How are the other parts?" Zou Yongdong was about to take out the processed cylinder when he heard a familiar voice coming from behind. He replied reflexively, "Well, even this one, ten cylinder blocks have been completed. The crankshaft parts and gears have also been completed, and the final polishing process is being carried out; the cylinder head and pipeline have been completed in the morning and are being assembled..."

While speaking, he suddenly realized who the person he was asking was. He quickly put the cylinder carefully, turned around and smiled embarrassedly, "Commander, I don't know it's you..."

"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 good impression of this young man who was serious about his work. His biological deputy brain scored him in the top 20. He was a good seedling worthy of vigorous cultivation. So he waved his hand and told him not to be restrained and to put the topic aside. "Then this batch of workpieces has finally been processed. After the honing is completed and the final cleaning process is carried out, we will be able to assemble tomorrow."

Honing uses oil stone to finely grind the cylinder running pipeline, and the grinding accuracy is higher than the processing accuracy. The domestic processing accuracy has not been improved. Many precision components are improved to aerospace level by fine polishing.

The small amount of boron nitride stone developed in the Military Division Laboratory can increase the polishing accuracy to an ultra-high accuracy of two thousandths of a micron, which is no less than the highest level abroad.

Guan Fei smiled with satisfaction as he watched Zou Yongdong send the cylinder with a trolley to hone.

This smile is not only satisfied with the fast processing speed, but also can be used in a final assembly immediately, but also a commendation to technical workers like Zou Yongdong.
Chapter completed!
