In 1962, a military camp in Bao'an County.
(Of course, someone must pass by with the car)
A large warehouse in the military camp was crowded with people, and many of them were wearing Zhongshan suits. They were obviously professors and researchers at all levels of intellectuals.
Everyone stared at a huge machine tool full of modern technology in the middle of the warehouse, or a "machining center".
On the front of the machine tool, the leader was staring at the working machine tool without blinking.
Leader Jing next to him looked at Lin Sanqi nervously and asked:
"Boy, this is what you are talking about a five-axis machine tool? We haven't heard of it before. Does the United States have it? And is this thing really that magical?"
Lin Sanqi scratched his head and thought to himself if I would tell the difference and advantages of five-axis machine tools and three-axis and four-axis machine tools, I guess readers would blame me for copying Baidu in the water number.
"Leader, I am also an amateur. Anyway, you should know that the most advanced machine tools in the world are four-axis, but our country does not. Developed countries are embargoing us.
It turns out that we have a good relationship with the Soviet Union, but the Soviet Union can only produce three-axis machine tools at most. Only then is he unwilling to sell it to us. So we only have one-axis and two-axis machine tools.
We all need to take some special parts to the Soviet Union and entrust them to help us with processing. Not only does it depend on their faces, but they also have to charge high processing fees, right? ”
Leader Jing was a little impatient when he heard this: "Tell me the key point!"
Even the leader's ears moved, but such a super big leader often doesn't speak easily because every word he says is worthwhile.
"The news I got is that a four-axis machine tool has an additional rotation axis based on the traditional three-axis machine tool; while a five-axis machine tool has an additional rotation axis based on the four-axis machine tool.
This rotation axis is usually the rotation axis of the tool, so that the tool can rotate in any direction along the machining surface without being restricted by the rotation plane. Note: Any two words are very important.
Therefore, the four-axis machining center is mainly suitable for the processing of flat parts, such as machine bases, panels and other workpieces.
The five-axis machining center is suitable for more complex three-dimensional curved surface processing, such as aircraft engine spare parts, rotating surfaces, ribs and other workpieces.
In addition to flying into the sky, it can also run on the road and drive in the sea. As long as it involves precision parts manufacturing, five-axis machine tools can play a decisive role. ”
Leader Jing led troops to fight. He turned out to be a medical student, so he naturally lacked understanding of the great power of five-axis machine tools.
But his lack of understanding does not mean that others do not know the goods.
Lin Sanqi got the machine tool, and there were several of the most advanced five-axis machine tools just reported. The leader personally rushed to Bao'an County as soon as possible.
The leaders also came with the bigwigs from various universities, key enterprises, arsenals and research institutes that were temporarily summoned by the capital and Shanghai.
In addition, there are many big shots across the country on the way to emerge urgently.
As soon as the leader arrived, he asked the local garrison to close the martial law and blockade and first-level combat readiness. From the tension of the superiors, it can be seen that the superiors are aware of goods and know the importance of the five-axis machine tools to the country.
Under everyone's attention, the red and white five-axis machine tool in front of me silkly made a piece of metal into a strange part.
When Lin Sanqi carried the part down and placed it on the table, he quickly surrounded a group of professors.
"Lao Fang, measure the data quickly!"
"A magical artifact, such precise parts were created in just a short while!"
"Yes, it turns out that we want the master to rub it with his hands. If one can't be rubbed in ten days and half a month, all the pieces will be scrapped if they make a little mistake. Now, we can produce them in batches."
"I just don't know how the precision is?"
The leader also leaned on the table anxiously, but he couldn't lean on the inside. A group of professors were busy measuring and researching, and no one paid attention to the leader. Finally, Professor Fang Jianian exclaimed:
"It's great to fully meet the requirements of parts drawing design. This is simply an industrial miracle."
The leader then spoke, his voice trembling:
"Professor Fang, how about it?"
Professor Fang Jiayuan happily took another part over and placed the two on the table at the same time. Then he laughed and said:
"Leader, look at these two parts, we used on the Dongfeng 1 missile. This part was made entirely by our nine-level fitter master. It took half a year and failed several times during this period.
Because manual operation will definitely produce errors, and the error of this component cannot exceed 10 microns. This error is already the limit of human beings, and ordinary workers cannot do it at all.
But the ninth-level fitter, what a valuable talent resource, how many people in the country are now? We can't bring all the ninth-level fitters to us. Should national production continue?
Now, with this machine, it can be worth 100, oh no, 1,000 level nine fitters. With this five-axis machine tool, we can immediately launch the Ma Dongfeng 2 and the Ma satellite. ”
When the green military uniforms heard this, they all became excited.
Rockets used to launch satellites, in fact, aren’t they just intercontinental missiles that can hit a beautiful country on the other side of the earth.
National defense, besides soldiers, the most important thing is weapons, such as the massive weapon missiles of this era.
Although we were able to invent the missile independently and successfully tested it, it could not be made in large quantities because various precision parts could not be produced on a large scale.
The newest ⊥Xiao⊥Speak⊥Send⊥Six⊥9⊥Book⊥⊥⊥⊥Back⊥⊥⊥⊥!
Just relying on some nine-level and eight-level fitters to polish slowly by hand, can they polish out parts this year?
For missiles, rockets, aircraft, etc., they are all composed of various precision components. If one component fails to meet the requirements or makes mistakes, it may lead to serious problems.
For example, how many planes crashed is because a certain component was aging and forgot to replace it.
For example, on January 28, 1986, the Challenger space shuttle exploded 73 seconds after it was launched, killing all seven astronauts.
The root cause of the accident was that there was a problem with the sealed O-Ring on the solid rocket booster.
This O-ring will harden in a low-temperature environment and cannot meet the sealing requirements, resulting in high-temperature gas leakage, which will eventually cause an explosion and lead to a tragedy.
At this time, another leader smiled and said:
"Our country has missile technology and design drawings, which means there is a lack of components to manufacture missiles, only theory but no practice. Now, with this machine tool, those precision parts will fall down one by one like dumplings.
With the parts, let's assemble them. The missiles are also mass-produced like dumplings. As long as we have the most advanced missiles in the world and the largest number, let’s try it out if the Americans and the Soviet Union dare to touch them. ”
Lin Sanqi was also overly excited and added:
"When we invent the atomic bomb, as long as we have our own missiles, we will load the atomic bombs onto missiles one by one, and aim hundreds or thousands at the United States, the Russians, and Japan. Do we see if they dare to move?"
A leader slapped the table with excitement:
"I wish I could give Jiang Fei a few missiles right now so that he would not eat well every day, not sleep, and even torture him to death."
Hahaha~~~~
The scene was filled with laughter.
Anyone knows that this magical five-axis machine tool can make any precision parts, which means that as long as we design drawings, we can create all weapons.
At this time, Lin Sanqi thought of the smuggling case between the Soviet Union and Toshiba Company, so he turned around and asked:
"Is anyone coming from the Navy?"
A leader nodded: "I am Lao Xiao of the Navy."
Lin Sanqi stood attentively and saluted: "Hello, Leader Xiao, I want to ask, can our country build submarines now? Or do we have the idea of making nuclear submarines?"
Leader Xiao was originally smiling, but when he heard the question behind him, his face changed and he looked at the largest leader in the center. (This chapter ends)
