"Recently, the state has given us an important task......"

In the past few days, the six shields of national defense have held several important meetings one after another, and Tianming, as an important player, also participated in these meetings.

Most of the attendees, except for General Xu Guoyuan, who was seated, were experts with glasses, white coats, and silver temples. Many of them are academician-level experts of the National Academy of Sciences, and each of them is a well-known designer and chief designer in various fields of science and technology! Take out any of them, and you can make a sound shock.

Today, there are a dozen sits here.

In terms of industrial exhibition, the leadership's attention has changed from the previous strategy of "independent research, keeping an eye on the international advanced level, and introducing high-tech talents and equipment in a timely manner" to the strategy of "leading by the six shields of national defense, researching high-tech, refined and cutting-edge equipment, and improving the overall industrial level of the country".

The state has developed a program of "Mother of Industry".

In many novels or materials, the concept of "industrial machine tool" is mentioned, and many people understand it as a machine. In fact, this is wrong, the "industrial machine" is actually a complete set of industrial machine tools that can produce all kinds of high, precise and cutting-edge parts. There are many types of these machine tools, with different functions, but the things produced can be composed of one machine.

Together, these machines are the production lines in the factory, which are industrial machines and symbols of the strength of the whole country.

There are a total of 13 kinds of machine tools such as piercing, pressing, punching, drilling, grinding, boring and milling, five-axis machining, etc., and each machine tool is required to be manufactured according to the highest manufacturing accuracy. When these machine tools are manufactured, and then the CNC system is installed, this base has become the cradle of the high-tech industrial base of country H.

The high-precision parts produced from this "cradle" will be transported to various factories across the country, assembled into new production lines, and then put on these production lines. It will be possible to produce better and more sophisticated car parts, airplane wings, electronic chips, and motor ...... One qiē started in this base 3oo meters underground.

This is an extremely large system plan, and it will not only require a lot of manpower, material and financial resources, but also a lot of time to realize it.

However, the feasibility of this plan is very high, they only need to start with one part, make one set at the end, put it together, make it work, and then the rest of the work. It's up to these machines to complete.

From 1 to 1oooo, as long as 1 is made, the 10,000 behind it is just a string of O's added after 1.

This is the so-called "Mother of Industry" program.

Xu Guoyuan said: "In addition to manufacturing 13 kinds of machine tools, we can also take a shortcut, that is, 3D printing technology," turning on the projector, he pointed to the picture above and continued: "This 3D printer is the largest 3D printer in the world, and it can print the length and width of objects." Over 6 meters! In a few days, a printer like this will be shipped, and I think it will make a huge difference in our hands! ”

After speaking, Commander Xu also glanced at Tianming.

Tianming was in a stunned state. Something as big as that house is a 3D printer? He couldn't help but ask Commander Xu next to him: "Commander, can a 3D printer also be used as an industrial machine tool?" Will it make something that is not strong? ”

3D printing uses material stacking technology, which sprays raw materials and adhesive materials through guò to pile up products layer by layer. Without stamping, pressing, forging and other processes, the printed things are indeed not as strong as ordinary industrial products.

Of course. The 3D printer mentioned above is a traditional 3D printer. The new 3D printer has solved the above problems through several technologies, such as fusion molding technology, laser sintering technology, vacuum tube electronic flow flow melting dust technology, which can be melted and cast while printing, and the quality of the industrial castings manufactured has fully reached the available standards.

It is said that the titanium alloy components printed by the 3D printer in H have been used in aircraft, which means that if we enter a wartime state, we will produce fighter bodies not one or two hundred per year, but thousands, tens of thousands.

Xu Guoyuan smiled, bloomed into a flower, and said: "Xiaoxu, our country may be a little worse than foreign countries in other aspects, but in 3D printing technology, we are not weaker than foreigners!" Do you know why our scientific and technological achievements have appeared in the past few years? It is because many of our breakthroughs have been achieved through 3D printers in Guò. ”

Another expert also smiled and said to Tianming: "Little comrade, the rocket used by our aerospace department has 3o% of the parts in it, which are manufactured by 3D printers, and it may be 5o% or 7o in the future. ”

"What? So awesome! Tianming was already so shocked by the technology that he couldn't express it.

"So, we can't be presumptuous, we are not as good as others, but we also have places that are stronger than others, in 3D printing, we dare not say that it is the first, but no one dares to say that it is better than us!" An expert said with pride on his face.

In fact, you can take an analogy, let's say that an Olympic Games in the field of industrial equipment is held, if the processing machine tool is a football project, then the 3D printer is a table tennis project, our football is not as good as others, but the technology to play table tennis is still shot.

After Commander Xu showed and explained more than a dozen machine tools to be manufactured one by one, he paused for half a minute, looked at Tianming next to him for a while, and his eyes were full of heat.

The other experts did the same, watching Tianming together.

"What are you all looking at me for?" Tianming was a little nervous to watch.

Xu Guoyuan said earnestly: "Xiaoxu, can the 'Mother of Industry Plan' be completed, in a short period of time!" It is a person, this person, that is, you, and only you, can let us take a shortcut of 1o years of struggle, Xiaoxu, are you willing to help us? ”

The conference room fell silent, all waiting for Tianming's answer.

Tianming said embarrassedly: "Commander, what you said is too polite, this is my obligation and my responsibility!" It's only a dozen machine tools, no problem, I promise to do the job quickly and well! ”

"Okay, well, with your words, we are relieved! Thank you, I want to thank you on behalf of the country! ”

After speaking. Commander Xu stood up and gave a straight military salute to Tianming, and he used a soldier's way to express his highest gratitude.

Suddenly! Tianming also immediately stood up, "Don't, Commander, you're too polite, it's all what I should do." ”

He walked over and wanted Commander Xu to put his hand down, but looking at his solemn posture, sacred and powerful, he didn't interrupt the ceremony. Instead, he also saluted the commander, lame.

"Hahaha, there is hope for national revival!" Commander Xu took Tianming's hand and laughed heartily,

Bang bang, I don't know who to start, there was applause in the conference room, and gradually, the applause converged. Applause. The experts present also stood up and laughed heartily.

……

Boom Boom! A continuous burst of explosions rang out from the base.

The area in the base is limited, and factories, research institutes, living quarters, warehouses, and the production and life of more than 2oooo people are in it. It has long been overcrowded, and there is no place to carry out the huge "mother of industry" program.

As early as the beginning of January, the base began to blow up rocks, and more than 1,000 engineers worked overtime. Working day and night, it lasted nearly a month, and an underground factory with an area of more than 3ooo square meters was chiseled out.

But this plant area accounts for less than one-seventh of the excavation tasks that the engineers need to complete. There are also two factories with an area of 8,000 and 10,000 square meters, which are also under construction, and they must strive to complete them within half a year, and the task is urgent, difficult and dangerous.

Yesterday, because of the bombing of the mountain, there was a large-scale landslide accident, and 13 engineering soldiers were buried.

The digging was forced to stop for a day.

After hearing the news, the people in the entire base were very depressed, and 13 soldiers died at a time, which was a relatively tragic accident in the history of the construction of this underground base, but there was no way to avoid it.

After Lan Luo told him about the matter, he stood up and immediately called Secretary He.

"Lao He, I said that there has been a lot of noise in the base recently, it turned out to be a bombing of the mountain, and more than a dozen soldiers have died recently, why don't you tell me about this? If I had helped open the mountain, this would not have happened. ”

Tianming felt that it was a pity that in the construction of many national defense projects, in order to catch up with the schedule, batch after batch of construction workers were sacrificed. On the Sichuan-Tibet Highway, 1 person per kilometer was sacrificed. The Karakoram Highway, which connects with Pakistan, sacrifices O.7 people per kilometer, and these projects are piled up with human lives.

He Xi sighed: "After sacrificing 13 soldiers, I can't help it, the base is still too small, and it won't be able to carry out new missions without expansion!" He asked, "You said you could help open the mountain?" How do you drive? ”

"Take me to the construction site to see, I will help you open the mountain how you want!"

When Secretary He and several construction experts came to the construction site with Tianming, the engineers started work again, and dozens of holes were dug out of a wall, and explosives and detonators had been placed in the holes, and they were about to explode.

"Why are you here?" The commander of the engineering corps who commanded the opening of the mountain said: "This side is about to explode, you guys hurry up and go to a safe place!" ”

Secretary He hurriedly came up and said: "Stop the explosion, the mountain structure in this place is complex, there is a transverse fault layer, and the blasting is too dangerous!" It happened two days ago, why did you do it again?! ”

"Long! The time given above is tight, how can you complete the task within half a year if you don't hurry up? The head of the regiment's dusty face was full of anxiety.

"That can't be a joke with the lives of the soldiers!" He Xi said angrily.

"Dismantle the explosives, and I'll do the work of opening the mountain." Tianming took a step forward and walked to a stone wall that had been blown up beyond recognition.

"Comrade, that place is dangerous, you can't go over!" The commander of the engineering corps, who was still negotiating with Secretary He, hurriedly ran over to pull Tianming aside.

"Captain Jiao, still listen to him, dismantle the explosives, let him do the work of opening the mountain."

After a lot of words, Secretary He explained to the head of the regiment Jiao, and finally under his order, he reluctantly asked the soldiers to dismantle the explosives and let Tianming walk to the stone wall.

The next one made him a little dumbfounded, first his eyes were dark, and then he was bright! In less than ten seconds, a boxy, six-sided cave like a smooth flat mirror appeared, as if it were a ghost.

Secretary He didn't explain so much, just said that what you see is a state secret secret, don't speak, open your ears to listen, just let go and do it, and after the project is completed, don't reveal anything about what you see to anyone.

"Yes!" Head Jiao saluted.

The next work was much easier for the officers and men of the engineering corps, and they could even describe it as "leisurely": As long as they drove a dump truck and waited on the side of the road, every half an hour or so, a pile of small squared stones would be placed in the body of the truck and loaded and pulled away.

In addition to some of these small stones being thrown away, some of them have to be left in the base to build houses, which solves the problem of moving bricks and stones for the base.

Tianming only worked for three days and completed the task. The engineers transported the stones for five days, and in the process of transporting the stones mechanically by Commander Jiao and his engineers, who had become numb, three underground rock chambers with an area of 8ooo, 12ooo and 2oooo square meters were formed.

Without the use of a kilogram of explosives, and without any vibrations, loud noises or noises, these chambers are not only structurally sturdy, but also maintain the stability of the rocky mountain. There were zero casualties during the construction process, and the construction cost seemed to be only a fraction of the original budget.

In five days, it took only five days to dig out the plant, which was far beyond Commander Xu's imagination, and almost immediately, hundreds of pieces of equipment transported by railway, highway and underground Great Wall were quickly put into these spacious and bright new factories after decoration......
