A military camp in Bao'an County in 1962.
(Of course, there have to be people and cars passing by)
A large warehouse in the military camp was crowded with people, many of whom were wearing Zhongshan suits and were obviously intellectuals, including professors and researchers at all levels.
Everyone stared at a huge machine tool, or "machining center," in the middle of the warehouse, which was full of modern technology.
In front of the machine tool, the leader was staring at the working machine without blinking.
Leader Jing beside him looked at Lin Sanqi nervously and asked:
"Hey kid, is this the five-axis machine tool you mentioned? We've never heard of it before. Does the US have one? Is this thing really that amazing?"
Lin Sanqi scratched his head and thought that if I talked about the differences and advantages of five-axis machine tools and three-axis and four-axis machine tools, readers would probably blame me for plagiarizing Baidu to increase the word count.
"Leader, I'm not an expert on this either. Anyway, you should know that the most advanced machine tools in the world right now are four-axis ones, but our country doesn't have them. Developed countries have embargoed them for us.
We used to have a good relationship with the Soviet Union, but the Soviet Union could only produce three-axis machine tools at best, and they refused to sell them to us. So we only had one- and two-axis machine tools.
We need to take some special parts to the Soviet Union and entrust them to process them for us. Not only do we have to look after their mood, but we also have to be charged exorbitant processing fees, right?"
Leader Jing was a little impatient after hearing this: "Get to the point!"
Even the leader's ears moved, but this kind of super leader often does not speak easily, because every word he says carries weight.
"The information I received is that a four-axis machine tool is based on a traditional three-axis machine tool with an additional rotary axis, while a five-axis machine tool is based on a four-axis machine tool with an additional rotary axis.
This rotation axis is usually the rotation axis of the tool, which allows the tool to rotate in any direction along the machining surface without being restricted by the rotation plane. Note: The two words "any" are important.
Therefore, the four-axis machining center is mainly suitable for processing 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 parts, rotating surfaces, ribs and other workpieces.
"Five-axis machine tools not only fly in the sky, but also operate on the road and in the sea. They play a decisive role in any industry involving the manufacture of precision parts."
Leader Jing led troops in battle and originally studied medicine, so naturally he didn't have enough understanding of the tremendous power of five-axis machine tools.
But his lack of knowledge does not mean that others do not know the value of things.
Lin Sanqi got the machine tools, including several of the most advanced five-axis machine tools. As soon as this matter was reported, the leader personally rushed to Bao'an County as soon as possible.
Following the leaders were bigwigs from various universities, key enterprises, arsenals, and research institutes who were urgently summoned from the capital and Shanghai.
In addition, many bigwigs from all over the country are on their way urgently.
As soon as the leader arrived, he asked the local garrison to impose a full blockade and martial law and be on level one combat readiness. From the level of tension at the top, it can be seen that the superiors are knowledgeable and know the importance of five-axis machine tools to the country.
Under everyone's gaze, the red and white five-axis machine tool smoothly processed a piece of metal into a strange component.
When Lin Sanqi took the component down and placed it on the table, a group of professors quickly gathered around him.
"Lao Fang, quickly measure the data!"
"What a divine artifact! Such precise components were created in just a short time!"
"Yes, in the past we had to have the craftsmen rub it by hand, but it would take them ten days or half a month to rub out a single piece. If there was even a slight mistake, the whole piece would be scrapped. Now it's better, we can mass-produce it."
"I just don't know how precise it is."
The leader also leaned against the table anxiously, but he couldn't get to the innermost part. A group of professors were busy measuring and researching, and no one paid any attention to the leader.
Finally, Professor Fang Jianian screamed:
"It completely complies with the design requirements of the component drawings. It's amazing! This is simply an industrial miracle."
The leader then spoke, his voice trembling:
"Professor Fang, how is it?"
Professor Fang Jiayuan happily took another component and placed both on the table. He then laughed and said,
"Leader, look at these two parts. They are used in the Dongfeng-1 missile. They were made entirely by hand by our ninth-level master fitter. It took a full six months, and we failed several times during that time.
Because manual operation will inevitably lead to production errors, and the error of this component cannot exceed 10 microns. This error is already the limit of human beings, and ordinary workers simply cannot do it.
But ninth-level fitters are such a valuable talent resource, and how many are there in the entire country? We can't just recruit all the ninth-level fitters here, because then how can national production continue?
Now, with this machine, we can completely replace 100, no, 1,000 ninth-level fitters. With this five-axis machine tool, we can immediately launch the Dongfeng-2 and even satellites."
When the green-uniformed soldiers at the scene heard this, they all became excited.
The rocket used to launch satellites, in fact, if the satellites are replaced with bombs, wouldn’t it be an intercontinental missile that can hit a beautiful country on the other side of the earth.
In national defense, besides soldiers, the most important thing is weapons, such as the missiles, the most lethal weapons of this era.
Although we were able to independently invent missiles and successfully test-fired them before, we were unable to produce them in large quantities because various precision components could not be produced on a large scale.
Just relying on some level 9 and level 8 fitters to slowly polish it by hand, how much can they produce a component in a year?
Missiles, rockets, airplanes, etc. are all made up of various precision parts. If even one part fails to meet the requirements or goes wrong, it may cause serious problems.
For example, many plane crashes are caused by the aging of a component and the forgetting to replace it.
For example, on January 28, 1986, the Challenger space shuttle exploded 73 seconds after launch, killing all seven astronauts on board.
The cause of the accident was a problem with the sealing rubber O-rings on the solid rocket boosters.
This type of O-ring will harden in a low-temperature environment and cannot meet the sealing requirements, causing high-temperature gas leakage, eventually causing an explosion and resulting in a tragedy.
At this time, another leader laughed and said:
"Our country has the missile technology and design drawings, but we lack the parts to manufacture them. We only have theory but no practice. Now, with this machine tool, those precision parts are being produced like dumplings."
"Once we have the parts, we can assemble them, and then missiles can be mass-produced like dumplings. As long as we have the world's most advanced missiles, in the largest quantities, we'll see if the Americans and the Soviets dare to touch us."
Lin Sanqi was also overly excited for a moment and added:
"Once we have invented the atomic bomb, as long as we have our own missiles, we can load them onto missiles, hundreds or thousands of them, and point them at the US, Russia, and Japan. Let's see if they dare to move."
One of the leaders slammed his hands on the table in excitement:
"I wish I could give Chiang Kai-shek a few missiles right now, so that he can't eat or sleep well every day. I'll torture him to death."
Hahahaha~~~~
Everyone at the scene burst into laughter.
Insiders know that this magical five-axis machine tool can produce any precision parts, which means that as long as we have the design drawings, we can manufacture all weapons.
At this time, Lin Sanqi thought of the smuggling case between the Soviet Union and Toshiba, so he turned around and asked:
"Is anyone from the navy coming?"
One of the leaders nodded and said, "I am Lao Xiao from the Navy."
Lin Sanqi stood at attention and saluted. "Hello, Leader Xiao. I'd like to ask, can our country manufacture submarines now? Or do we have any plans to manufacture nuclear submarines?"
Leader Xiao was originally smiling, but his expression changed when he heard the following question. He looked at the most important leader in the center of the field. (End of this chapter)
