(Originally, I said that I would have added updates today, and I didn’t go to bed at around 4 a.m., and then I got a contract for the new book in the afternoon. Today I can only update two times. I will continue to recommend votes for the new book "Three Realms Teahouse" and collect it)

If you express sincere words to the depths of your heart, you can easily move people.

Even if Liu Yijiu asked herself that she would not be moved easily, she had a hard heart, but she was moved by the other party here.

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

"I will tell them about this. Of course, funds are definitely indispensable. Large five-axis machining centers, heavy-duty CNC sleeper trucks, heavy-duty CNC vertical trucks, and heavy-duty boring and milling machines can all set up projects to help you transform. With these heavy-duty equipment, they can be transformed into manual and automatic integration, and their technical level can be improved quickly..." 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 Academy is not enough to support the development needs of the entire domestic industrial system, and no unit can do it. It can only meet partial use and promote the progress of the entire industrial system.

Top-level heavy equipment is a huge problem in the world. When China breaks through the five-axis machining center and challenges super heavy equipment with greater processing capabilities, China is much more difficult than any country.

Basic industries determine the top industries.

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

Therefore, Liu Yijiu could only wait slowly. The problems of materials and processing technology are not only plaguing China, but also the main reason for the development of scientific and technological level in any country in the world.

The current problems with the battleship spindle and propulsion rudder are caused by these two aspects, and the heavy machine tools of the Ninth Academy are also the same as those of these two aspects.

In terms of CNC machine tools, there are too many types that need to be studied and too many technologies that need to be broken through.

It is not that other machine tool factories in China do not have research capabilities, but that the top technology in the Ninth Hospital has always been in hand in this regard. Other units are also developing, but the speed is not as fast as the Ninth Hospital.

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

The current situation is obviously much better than before, and it is not a little bit stronger than the previous one. However, because of the development of more projects, there are higher requirements for more advanced and higher precision CNC machine tools and processing equipment.

"I'm really grateful!" Qin Kun looked surprised. "I'll apply for special funds from the higher authorities."

After saying that, he took Liu Yijiu to continue to learn about production.

There are no more than ten equipment in the entire workshop, but it does not make the huge workshop feel empty at all.

This is what it is for heavy equipment processing plants.

On the huge vertical lathe, there are huge propellers slowly being installed. The broken iron chips as thick as fingers are constantly falling, and the huge centrifugal force generated by the spindle drives the chuck is thrown out... and the spindle on the horizontal lathe is constantly falling as the tool holder moves.

The Shumi Factory, a floor boring machine two or three people tall, is running at high speed under the operation of a relatively short and thin figure of the workers.

All of the above are heavy parts needed by the battleship.

A vertical lathe stopped, Liu Yijiu walked forward, climbed onto the machine tool with the help of workers, and observed the knife marks on the part of the propeller processing.

"In this case, we have to rely on the workers' experience to ensure it manually. Especially at the connection between the two steps, it needs to be processed into an arc to increase the strength. When there is no CNC machine tool, we can only rely on the worker's hands to cooperate, and at the same time, the two axes on the machine tool are moved into an arc. This is only done on the processing of small machine tools." Qin Kun thought Liu Yijiu did not understand this, so he explained to Liu Yijiu.

Liu Yijiu continued his words, "Doesn't large-scale machine tools be processed by forming tools? This kind of unconnected cuts that cannot be completely connected will also cause stress concentration at the cuts. During the use of parts, this stress concentration phenomenon will gradually expand..."

When Qin Kun and the workers around him were all surprised when they heard Liu Yijiu say this.

How many people can understand these professional things?

Only technicians involved in this area and managers from grassroots backgrounds can know the technical details of these professionals.

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

Liu Yijiu didn't say anything, and a black guard beside him said to these guys with contempt, "Director Liu has been playing machine tools since he was three years old, and he can't do anything about turning, milling, and grinding. Especially CNC equipment, several CNC machine tools he brought back from abroad were designed and modified by Director Liu. Our domestic CNC machine tools were all made by Director Liu..."

Although this is suspected of bragging, no one has expressed it.

There was a sound of praise, and no one believed that someone would start playing machine tools at the age of three.

Of course, it is normal for workers to play in the workshop, and it is understandable if you understand it early.

After coming out of the heavy-duty machining workshop, Liu Yijiu's face was very heavy.

Qin Kun did not mention this matter again, but he guaranteed that as long as CNC equipment is available, it will definitely provide higher quality and longer service life.

Liu Yijiu directly reassured him and left Changfeng Machinery Factory and did not go to 701 again. Although they were all in a city and were very close, it took only a few minutes to take a bus in this era. He still did not go, but returned to Chengdu directly.

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

This factory was originally a supporting unit in the third line of Rongcheng, with only a few hundred people. After more than ten years of development, it has already had thousands of employees, and the factory area has expanded by more than ten times.

This is one of the best-performance units among private product units.

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 time one is produced, the test has not been completed, and the people who are outside the factory waiting here are greeted by other factories to move their people to the car sent by their units.

"The fight starts, the fight starts..." Liu Yijiu just arrived here, and Luo Yuanxiang finished greetings with him and was about to start introducing the situation in the factory. A middle-aged woman rushed towards him and called out to Luo Yuanxiang, "Director, Aerospace and Shen Fei's people have started fighting..."

"What's going on?" Liu Yijiu was stunned.

This is the territory of the Ninth Courtyard, right?

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

"Director Liu, I am just going to introduce this situation to you. Although we are constantly expanding production scale and improving production capacity, we still cannot meet market demand in the manufacturing of top-level CNC machine tools. At the same time, we have to cope with the huge number of export orders. Foreign countries require top-level CNC machining centers, so this aspect has always been very tight. The orders have been scheduled to 1993, so each unit sent personnel to us to watch, unless it is exported, as long as it is supplied to domestic ones, they will grab one. 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.

Fighting to grab a machine tool?

Will such a thing actually happen?

And it was the aerospace people who started working with the Chen Fei people.

"Does our three-axis machining center business be distributed to several major domestic CNC machine tool factories? They have taken away the technology from us, so it should be able to supply it, right? We should make every effort to produce CNC machine tools with a four-axis or above and heavy-duty CNC machine tools?"

The five-axis business has been transferred from the third zone to this side, but equipment with very high accuracy requirements in the main shaft and roller screw are still being produced in the mountains.

Currently, Hongshan Machinery Factory is preparing to build a ball screw factory. After all, this kind of screw is not just used in CNC machine tools.

Logically speaking, domestic private product units do not have much chance to obtain top-level CNC machine tools, and there is no problem supplying them to military-industrial units.

According to the principles of the Ninth Academy, the requirements for military industrial systems are given priority, and then state-owned enterprises, and finally private enterprises affiliated with collective ownership units. At the same time, most units only need a three-axis machining center and a CNC lathe. Where does this happen?

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

Liu Yijiu glared at him, and his feet did not slow down, "Then let's talk about it short."

"For the sake of profit, other units are not very reliable in production, and the equipment sold often fails. You should know that for most units, CNC machine tools are the top-notch equipment. Many units even build constant temperature and dust-free factories to install these equipment. As a result, CNC machine tools purchased from other factories have problems every once in a while, and they give up and instead purchase from us..."

For the sake of profit, it is definitely not a minority of state-owned units that make themselves shoddy and then kill themselves because of bad reputation in the market.

Even in Liu Yijiu's original world, many times people shook their heads at the domestic industry, and it was also for this reason.
