Super military empire

Chapter 1349 The two systems of aerospace and aviation are doing it

(Originally, I said that I would add a change today. I only went to bed after four in the morning, and then I got a new book contract in the afternoon. Today I can only change it twice. I will continue to ask for the new book "Three Realms Tea House" and collect it)

Sincere words sent to the bottom of your heart can easily move people.

Rao Liu Yijiu asked himself that he would not be easily moved by others. He had a heart of iron and stone, but he was also moved by the other side here.

This is a pure national defense science and technology worker, although he is a fat man.

"I'll talk to them about this matter. Of course, funding is definitely indispensable. Large five-axis machining centers, heavy CNC horizontal lathes, heavy CNC vertical lathes, and CNC control mechanisms for heavy boring and milling machines can all be specially set up. The project helps you to transform. With these heavy equipment, transforming into manual and automatic integration, the technical level can be quickly improved..." Liu Yijiu made a promise.

The development of heavy-duty CNC equipment is a problem that any country's top manufacturing industry must face.

The development of the Ninth Institute is not enough to support the development of the entire domestic industrial system, and no single unit will work.Solely it can only meet partial use and promote the progress of the entire industrial system.

The top heavy equipment is a huge problem in the world. When it broke through the five-axis machining center and challenged the super heavy equipment with greater processing capacity, China encountered more difficulties than any other country.

The basic industry determines the top industry.

If China does not have a complete industrial system, this development will be even more painful.

Therefore, Liu Yijiu can only wait slowly. The problems of materials and processing technology not only trouble China, but also the main reason for the development of science and technology in any country in the world.

The current problems with the main shaft and the propulsion rudder of the battleship are caused by these two aspects, and the heavy-duty machine tools of the Ninth Academy are also caused by these two aspects.

Regarding CNC machine tools, there are too many types to be studied, and too many technologies to be broken through.

It's not that other domestic machine tool factories have no research capabilities, but the Ninth Institute has always held top technology in this regard. Other units are also developing, but they are not as fast as the Ninth Institute.

According to Liu Yijiu's world, it was not until 1989 that China obtained a few four-axis machining centers from Germany.

The current situation is obviously much better than before. The technical foundation is not a little bit stronger, but because of the expansion of more projects, there are higher requirements for more advanced and higher precision CNC machine tools and processing equipment.

"Thank you so much!" Qin Kun looked surprised."I will apply for special funds from above."

After speaking, I took Liu Yijiu to continue to learn about production.

In the whole workshop, there are no more than ten equipments, but it does not make the huge workshop feel empty.

This is the case for heavy equipment processing plants.

On the top of the huge vertical lathe, a huge propeller is slowly being installed. The iron scraps as thick as fingers are constantly falling, and the huge centrifugal force generated by the spindle driven by the chuck is thrown out. The spindle above the horizontal lathe is It keeps falling as the knife holder moves.

In the mill of several meters, floor-standing boring machines with two or three people tall, and huge gantry milling machines occupying one-third of the workshop area, are operating at high speed under the operation of relatively short and thin workers.

Above, they are all heavy parts needed by battleships.

A vertical lathe stopped, Liu Yijiu stepped forward and climbed onto the machine with the help of the workers to observe the knife marks on the parts processed by the propeller.

"This must be manually guaranteed by the workers’ experience. Especially the two steps at the junction need to be machined into arcs to increase strength. When there is no CNC machine tool, you can only rely on the workers’ hands to cooperate and let the machine The upper two axes move and process into circular arcs. This is only performed on small machine tools." Qin Kun thought that Liu Yijiu didn't understand this, and explained to Liu Yijiu.

Liu Yijiu went on to say, “Doesn’t large-scale machine tools rely on forming tools for processing? This is impossible to completely connect without tool marks, and stress concentration will also occur at the tool marks. During the use of parts, During this period, this stress concentration phenomenon will gradually expand..."

When Liu Yijiu said this, Qin Kun and the workers around him were all surprised.

The chiefs above, how many people can know these professional things?

Only the technical personnel involved in this area and the managers from the grassroots level can know the technical details of these professions.

"Director Liu was born in the first line?" Qin Kun asked in surprise.

Liu Yijiu didn't speak, and a black guard next to him said to these guys with contempt, "Director Liu has been playing machine tools since he was three years old, and he has always been able to mill and polish vehicle tongs. Especially. It is numerical control equipment. The several numerical control machine tools brought back from abroad were designed and transformed by Director Liu. Our domestic numerical control machine tools were all made by Director Liu..."

Although this was a bragging suspicion, no one expressed it.

With a sound of praise, no one believed that anyone would start playing machine tools at the age of three.

Of course, it is normal for the children of workers to play in the workshop, and they can understand it early.

After coming out of the heavy machinery processing workshop, Liu Yijiu's face was very heavy.

Qin Kun didn't mention this matter again, but he promised that as long as CNC equipment is available, it will definitely be able to provide higher quality and longer service life parts.

Liu Yijiu directly assured him that he left the Changfeng Machinery Factory and did not go to 701. Although they were all in the same city and were very close to each other, he still did not go by car in this era for a few minutes. He went straight back to Rongcheng.

I stayed overnight in Rongcheng, and arrived at the Hongshan Machinery Factory, which specializes in CNC machine tools, early the next morning.

This factory, originally a third-line supporting unit in Chengdu, has only a few hundred people. After more than ten years of development, it has thousands of employees and the area of ​​the factory has expanded more than tenfold.

This is one of the most profitable units among civilian products.

There are a large number of cars waiting in line outside the factory area. The country needs a large number of CNC machine tools. Almost every one produced and the test has not been completely completed, it was moved by the people waiting for them to be greeted by other factory outsiders. On the car sent by your own unit.

"It's fighting, it's fighting..." Liu Yijiu just arrived here, Luo Yuanxiang finished the greeting with him, and was about to introduce the situation in the factory. A middle-aged woman rushed over here, her mouth facing each other. Luo Yuanxiang called, "Director, Aerospace has a fight with the people from Shen Fei..."

"What's going on?" Liu Yijiu was taken aback.

Is this the site of the Ninth Hospital?

Aerospace and aviation are originally two systems. When they fight, how can they fight in their own territory?

"Director Liu, I am going to introduce you to this situation. Although we continue to expand production scale and increase production capacity, we still cannot meet market demand in the manufacture of top CNC machine tools. At the same time, we have to deal with exports. For the huge number of orders, what foreign countries want are top-level CNC machining centers. Therefore, this aspect has always been very tight. The current orders have been queued to 1993, so each unit sent personnel to our side to stare, Unless it is those exported, as long as it is supplied domestically, one will get one when it comes out. This kind of thing is very common in the past two years..." While quickly following the woman in work clothes toward the warehouse area.

Liu Yijiu's face suddenly became exciting.

Fight for machine tools?

This kind of thing will happen?

Moreover, the people in the spaceflight and the people in Shen Fei started to work.

"Our three-axis machining center business is not distributed to several major domestic CNC machine tool factories? They took away the technology from us, should they be able to supply it? We should fully produce CNC machine tools with more than four axes and heavy CNC machine tools. ?"

The five-axis business has been transferred from the third area to this side, but the equipment with very high precision requirements such as spindles and roller screws are still produced in the mountain.

At present, Hongshan Machinery Plant is preparing to build a ball screw plant. After all, this type of screw is not only used by CNC machine tools.

It stands to reason that domestic civilian units do not have much opportunity to obtain top-level CNC machine tools, and there is no problem in supplying them to military units.

According to the principles of the Ninth Academy, the supply of the military industry system is given priority, followed by state-owned enterprises, and finally private enterprises affiliated to collectively-owned units.At the same time, most units only need three-axis machining centers and CNC lathes. Where can such things happen?

"This matter is a long story." Luo Yuanxiang looked helpless.

Liu Yijiu glared at him, and didn't slow down on his feet, "Then make a long story short."

"For the benefit of other units, the quality is not very reliable during production. The equipment sold often fails. You should know that for most units, CNC machine tools are the top equipment. Many units They even built a constant temperature and dust-free workshop to house these equipment. As a result, the CNC machine tools purchased from other factories had problems, they gave up and purchased from us..."

It is definitely not a minority of state-owned units that are shoddy for the sake of profit, and then die because of poor market reputation.

Even in Liu Yijiu's original world, people often shook their heads at domestic production, and this was also the reason.

After all, what an official needs is grades. When grades come out, he will go up, and then those who take over will find that although it looks like a strong momentum of development, there are countless drawbacks. If you want to change, this is impossible. They cannot bear the fault of the predecessor. Therefore, they can further increase production, ensure profits, show their political achievements, and climb up. What happens to the people behind will also be ignored.
