ps: Thank you readers for the great "avenue seeking" to heaven to vote for two monthly tickets, thank you ^_^ for finally driving out the second watch on Wednesday, it's not easy, heaven is here to cheekily ask for a collection, red tickets, monthly passes and rewards, I hope everyone can give a lot of help o (n_n) o haha~

The main plane of the Yanhuang Republic, the 303rd of a region in the northwest region. Speaking of this 303 Institute, it is directly subordinate to the General Armament Department of the Yanhuang Army, and is an extremely important military industrial unit of the Yanhuang Republic, specializing in the research and manufacture of military equipment, especially the production of CNC machine tools and other equipment used for the direct manufacture of military ships, aircraft, and rocket engines.

At this time, in a bright factory building of the 303 Institute, Han Yi and two employees of the 303 Institute in Liuyuan were talking. Han Yi is 37 years old, rich in social experience, stable and orderly in character, Yanagihara is 28 years old, relatively young, and his passion is still there, but it also brings some frizzy problems.

"Brother Han Yi, come and see, I finally processed a 0.0001 mm part!" Liu Yuan, who was excited, said loudly at Han Yi who was not far away.

"Oh? Show me. Hearing Yanagihara's words, Han Yi, who was busy with his work next to the machine tool, raised his head and put down the work at hand, and strode to Yanagihara's side.

"Here you go, show me quickly, how do you feel?" Liu Yuan took out the parts that had just been processed with a CNC machine tool and held them to Han Yi like a child offering treasures.

"Hmm~~" After measuring and identifying with his eyes and monitoring equipment, Han Yi nodded slowly, and then said: "Yes, the accuracy has indeed reached 0.0001 mm!" Then he calmly put down the parts in his hand and slowly walked to his workbench.

"Hey! Brother Han, it's not like that~~, why is the mood so low, it took me half a month to figure out it, just looking through those operation manuals, my eyes almost spent, how can you praise me more! The child offered the treasure, but Yanagihara, who did not get the loud praise he imagined, muttered dissatisfiedly.

"Huh? I'm sorry, I didn't mean that! Hearing Liu Yuan's words, knowing that his behavior was somewhat impolite, Han Yi hurriedly explained: "It's just that some things have made me depressed recently, so I don't have much interest in doing anything!" ”

"Huh? What's the matter, Brother Han, who provoked you, say! Brother, I'm looking for someone to help you calm him! Hearing Han Yi's words, Liu Yuan immediately put on the air of an old boy and said arrogantly.

"You're biased, how can I offend people as a slow son, it's just that I've been sulking at the machine recently!" Hearing Liu Yuan's arrogant words, Han Yi couldn't help but say happily.

"Angry with the machine? How did it mess with you? For Han Yi's answer, Liu Yuan was very puzzled and asked.

"Let me ask you, how many of the tools you use to make 0.0001 mm parts are made by us." Han Yi asked.

"Domestic? It seems that most of the tools are German or Japanese. Yanagihara raised the screwdriver in his hand, looked at it, and said.

"Take a closer look at the equipment around us!" Han Yi prompted.

"Equipment? It's all very good, it's quite advanced in the world, of course, it's not the top, but the first-class can still be ranked first, what's wrong with these? Yanagihara carefully scanned the entire plant, large and small, and replied blankly.

"Pay attention to their nameplates!"

"Huh? I remember seeing it, made in Germany or in the Japanese Invaders! ”

"I've spent some time these days, and I have counted that in our entire factory, only 20% of the equipment produced by ourselves is foreign, and the remaining 80% is foreign, of which 35% are from Germany and 45% are from the Japanese devils." Han Yi said.

"It seems to be about the same, and I feel like it's roughly the same proportion." Yanagihara replied.

"Then do you remember what the teacher explained when we were in college and the relationship between the production line and the industrial machine tool?" Han Yi asked.

"I know this, those professors described it very vividly, and it is easy to remember." Hearing Han Yi ask about the university's courses, Yanagihara replied very confidently: "Industrial machine tools, simply put, are machines that produce machines, high-precision machine tools produce low-precision machine tools, low-precision machine tools regenerate ordinary equipment and production lines, and ordinary equipment and production lines regenerate the goods we need, such as automobiles, motorcycles, and so on." ”

"Yes, then let me ask you, are these foreign equipment imported by us now low-precision machine or ordinary equipment and production line?" Hearing Yanagihara's answer, Han Yi was very satisfied and continued to ask.

"Of course, it's equipment, because of the Batumi embargo, even if it's a low-precision mother machine abroad, it's hard for us to buy it."

"Yes, so we can only spend huge sums of money again and again to buy foreign equipment and production lines, and after this batch of technologies is eliminated, we can only abandon it because we can't upgrade it ourselves, and continue to spend a lot of money to re-import!" Han Yi continued.

"This can't be helped, the quality of domestic machine tools, you know, is not used at all." Hearing Han Yi's emotion, Liu Yuan was also very touched in his heart, and said: "Let's not talk about anything else, just a speed index, now the maximum speed of domestic lathes is 1500 per minute, and imported ones can reach 4000~5000 per minute, which is too bad." What's more, in addition to speed, there are a series of problems such as vibration, noise, wear, and short equipment life. ”

"Do you know how much this imported equipment costs?" Han Yi then asked.

"I haven't inquired about this, and I don't worry too much, so I don't know."

"Whether I'm angry or depressed, in fact, I read an article by chance, and I realized how expensive these things are," Han Yi sighed and said, "Let's put it this way, a small drill bit for high-precision processing, we just can't make it!" It costs thousands to buy Japanese imports, and a complete set of RO/E genuine software costs nearly 80 million yuan! Now the CNC machine tool of this machining center we have at hand is made in Germany, the CNC computer part is made in Germany, the processing software is still made in Germany, even a turning tool, a drill, most of them are also made by the Japanese, think about how much it costs! ”

"But I heard that we haven't made great progress in CNC machine tools, and it seems that there are still products exported to Europe?" When Yanagihara heard Han Yi's answer, he was a little confused and asked.

"Those 'show' components are the majority, in fact, they have not really been fully utilized, and now the problem is an AC servo motor, our country has not yet fully understood, this AC servo motor is an optical, mechanical, electronic complex. The other is the high-precision ball screw used in the self-produced machine tool, the bearings are basically imported, mainly to buy the Japanese Kou, our self-produced ball screws, bearings in terms of accuracy, life There are many problems, and the indicators are not up to standard. ”

"Why buy a little devil?" Hearing that his factory was occupied by little devils, the half-angry "Yanagihara" felt very uncomfortable and asked.

"Mainly because in the early days, the German system was not very suitable for our power grid, and our power grid was not stable enough, such as the electronic servo module of the German Siemens system was particularly easy to burn out. The Japanese are different, their systems are not easy to burn out, and the cost of use is relatively low. In addition, the Germans also do not pay much attention to our Yanhuang market, their system equipment is not only expensive, but also the Chineseization has only recently begun. ”

"Grandma's, although this choice is beneficial to us, but as soon as I hear that the little devil has won, my mother's feeling is really twisted!" Liu Yuan smacked his lips and said dissatisfied.

"No way, we need to compromise in front of reality, after all, the same performance, you can save a lot of money for research and development," Han Yi replied, "Now the most bullish machine tools are Mazak in Japan and Siemens in Germany, the so-called domestic CNC machine tools in our country, I am afraid that they can only produce the bed and some simple parts." The CNC part is basically either imported by foreign capital or the product of a joint venture. Remember that Qinghai machine, sell a processing center to build a person, hey~~ are forced. Let's take a look at the Jiji, it's all made by the Eight-Nation Alliance, okay, okay, let's not talk about it, we can't change these anyway, so let's do what we should do! ”

"Understood, I know, alas~~ Who let us talk lightly!"

"Hehe, stinky boy, you're still going to have to get sucked!"

"Haha, Brother Han, don't be angry, how about we go out and rub it today, I'll have a treat!"

"Good idea, let's go!"

At the same time, more than 400 kilometers away from the 303 Institute, there was a hidden military base of the Yan and Huang Army. Da Mao of the 303 Institute, Director Qian is taking several cadres in his institute and several pillars from other research institutes in China to analyze and study the Siemens five-axis linkage machining center that Wang Fan traded to the Yanhuang Republic.

"Tsk, good thing!" Dean Qian of the 303 Institute said to the people around him while reading the operation manual of the machine and equipment (Wang Fan asked Yadi to help translate it into Yanhuangwen, which is convenient to read in one step).

"Hehe, old money, have you seen enough, I can see that your eyes are shining with thieves!" Director Wang of the 311 Institute is also an authoritative expert in domestic machinery manufacturing in Yanhuang, and at this time he is also like a child, with a red face and bright eyes looking at the five-axis linkage CNC machine tool.

"Hey, Lao Wang, your hands are itchy!" Dean Qian and Dean Wang are old friends, and they are not polite at all.

"That's, I never dreamed that I would get a set of German industrial machine tools, damn, it's really cool, although this is not the highest precision, but it is enough to solve a lot of problems we are facing now!" Director Wang rubbed his hands together and replied.

"Be content, with this, our country has saved at least 20 years." Director Qian, who is well aware of the current situation of Yanhuang machining, said.

"Yes, hey~~ Who makes mechanical design and manufacturing not be able to achieve leapfrog development like some industries, even if it is a little bit of coincidence." Director Wang has been working in machinery all his life, and he is also deeply touched, "You see, you want to process products with an accuracy of ±0.0001, but the accuracy that you can achieve with the machine tool at hand is only ±0.1, so there is no way, you can only design a machine tool with an accuracy of ± 0.01, and then process it with a machine tool with an accuracy of 0.1, and then reciprocate until it meets the requirements." How long does such a reincarnation take, often in ten years, those gringos are fucking ghosts, the machine tools exported to us can only ensure the processing of higher precision products, but can not guarantee that they can manufacture high-precision mother machines, and what is even more hateful is that we can only introduce other people's second- and third-rate production lines (few countries are willing to sell first-class production lines to Yanhuang), the little devils are very careful, and have maintained a technological gap with us for decades. It's so breathless! ”

"Speaking of the right character, I think it's not all about the equipment, the worker factor is also very big, now the vast majority of young people who have just graduated are more impetuous, I remember when I was young, I met the master who could see the temperature of the molten steel in the boiler with his eyes, the error was within 5 degrees, and the carbon content could be estimated according to the splashing of the molten steel." Director Qian said in defense.

"The one you said is the eyesight that took 20 years to practice, and now it's not that much, and no one wants to suffer that anymore, now it's all CNC, it turns out that we manufacture a complex part on the aircraft, and it takes a lot of workers such as lathes, millers, grinders, line painters, heat treatment workers, etc. to work together for several months, resulting in a large number of scrapped parts. Now to what extent is it abroad, with the latest composite CNC machine tools in a few days or even a few hours to do it all, and the accuracy is higher than your design, high precision of parts means long life, good reliability. Moreover, the adaptability of CNC is also super high, the parts have changed, just change the program, and reduce the human factor to a minimum. In the past, in the factory, if anyone knows how to drive turbines and worms, they can't practice for 10 years and 8 years, but if they really master it, they are very good! Director Wang did not fully agree with Lao Qian's point of view and continued.

"Hehe, Lao Qian, Lao Wang, don't break it blindly, now Lao Maozi's way is no longer feasible, they produce a shaft, they have to build a special production line, with a number of special machine tools, the advantage is that the batch is easy to go up, but once the parameters of this shaft have changed, the line will be scrapped, and the production personnel will have nothing to do. At the beginning, it is good to say that there was a great demand during the war years and the Cold War years, but now the entire international situation has changed, and from 1960 to 1980, we were like it, and one state-owned factory and one product were produced for 20 years. As a result, after 1980, as soon as the commodity economy was developed, these factories could not adapt to the changing market at all, and a number of enterprises went bankrupt and a large number of workers were laid off. Now pay attention to the small batch of single pieces, and the way of professional machine tools has come to an end. Deputy Minister Zhang of General Armament, who was standing on the side, saw that the second elder was full of emotion, and couldn't help but remind.

"Hehe, that's, that's, Minister Gao, we have nothing else, it's just that the number of machining center machines is a little small, it would be better if we could have a few more sets!" After Director Wang heard Vice Minister Gao's squeak, he changed the topic and asked.

"I said Lao Wang, we can know enough, ah, this set is also a fight for the country's life, only to get it, you have to cherish it, people and machines do not stop, now I have the aviation bureau, the space bureau and the shipyard, the submarine department are waiting for the equipment to get out of the pot, all kinds of engine parts, submarine propellers and other manufacturing rework needs are piled up, you can learn at the fastest speed, while producing, while imitating, give me the fastest time to overcome it!" Thinking of the stack of headache-inducing documents on his desk, Vice Minister Gao couldn't help but instruct. Of course, when I heard Lao Wang's question, I couldn't help but think in my heart, if I could really buy a few more sets from that mysterious person, wouldn't everything be solved, well, it seems that I need to ask the minister again.

"Don't worry, I'm here to cover the roll to ensure that the performance is thoroughly understood and the equipment is completed as soon as possible!" Director Qian patted his chest and said.

"The gringos always say that we are a 'sample country', hum, what do you say about the laboratory samples are qualified, once the factory production, the index will fall, damn, isn't it just bullying our processing technology, I also set up a military order, do not overcome the difficulties of imitation and never go out of the gate of the base." Director Wang also excitedly played the ticket.

"Okay, then I'll leave it to you!"

Just when the "pillars" of Yanhuang in the base were planning to do a big job, an accident that happened on the side of the Japanese brought about a sharp change in the international situation.
