Lin Qiangsheng's five sets of various five-axis linkage CNC machining centers from Comau are his biggest secrets, so Lin Qiangsheng placed them in the basement to protect them tightly.

After changing clothes and removing dust, Lin Qiangsheng and Gu Ming walked through the passage and entered the real room.

This is the precision instrument laboratory, which occupies the space of the basement floor, and the first floor here is much higher than the ordinary one, and the whole small building is actually its supporting research unit.

There is an old professor in the research room with eight apprentices to learn basic theoretical knowledge, it can be seen that the old professor is not very proficient in these foreign CNC equipment, but this does not affect him to teach some basic knowledge of machine tools. At the same time, in the process of teaching, the old professor is also learning and exploring these advanced machine tools on his own.

Since Professor Dong Fang was rehabilitated, he was transferred from the foundry to the Railway College, and because he was almost 70 years old, even if he was transferred back to the college, the schoolwork arranged for him by the college would be relaxed.

The old man is not accustomed to a quiet life, in the foundry are heavy labor, and then squatting in the factory every day to read drawings and draw drawings, the busy life is suitable for him, and he feels all kinds of discomfort when he is free.

At this time, Lin Qiangsheng asked Gu Ming to invite Professor Dong Fang to visit the precision instrument laboratory, and Professor Dong Fang was surprised to see such precision instruments.

Among the eight apprentices, there are 3 girls, one of whom is about 20 years old, a slim and slim woman, a very iconic beauty, Zou Xue.

Lin Qiangsheng got her from the mold workshop, and the girl knew that it was Lin Qiangsheng's meaning, so she packed up her things and came to the real room from the automobile factory without even asking, and she didn't even care if it was an iron rice bowl here.

The remaining seven people were all recommended by Gu Ming and Zou Xue, and Zou Xue also called her two good sisters in the mold workshop.

Lin Qiangsheng specially selected young people around 20 years old who are willing to learn, educated, and patient. Lin Qiangsheng hopes that they can quickly master the operation of CNC machine tools.

Dong Fang saw someone coming in, turned his head to look, and saw that the tall young man at the head was a little familiar, but he couldn't remember who it was for a while.

Lin Qiangsheng smiled and said to Professor Dong Fang: "Professor Dong, it's me, Lin Qiangsheng!" ”

"Oh!" Dong Fang clapped his hands. Haha laughed: "I didn't expect you to grow so tall, when you first came to the foundry, you were still a teenager, and now you have become a young man!" ”

Lin Qiangsheng smiled and asked, "How is it about working here?" Can you make the most of your old heat? ”

Dong Fang pursed his lips and nodded, looked at the CNC machine tools in the clean workshop, and said with appreciation: "These machine tools are real precision machine tools, I don't ask where you got them, but you have to use them carefully and make more contributions to our country!" ”

Lin Qiangsheng and Zou Xue looked at each other, and the two looked at each other and smiled. Turning his head and pulling Dong Lao, he stepped aside and said, "I don't just want to use them!" I still want to copy them, Dong Lao, you want to help me! ”

Dong Fang looked up at Lin Qiangsheng, with a funny and happy look on his face, he couldn't help nodding and said, "Hmm! With such equipment, it would be a big waste not to study them clearly! ”

He then said to Lin Qiangsheng: "You kid, I don't know what your relationship is with this foreign-funded company, but you can command this real office." I don't think you're a simple kid! ”

The old man continued: "It is not an overnight thing to study them. You're going to do this with just a few of us? ”

Lin Qiangsheng looked at the young people in the room, like Zou Xue, a few people were born in the mold workshop, and a few people were born in the machining workshop, but they are all beginners for CNC machine tools.

Lin Qiangsheng looked at Professor Dong Fang, pondered for a moment and said, "Professor Dong, I must ensure the safety of these devices. The news that they can't be allowed to spread outside the real room! Therefore, I have to be cautious in the selection of personnel! ”

These people were all given a settling-in fee, and Lin Qiangsheng also promised them to solve the housing problem, which made them come here willingly.

Dong Fang nodded and said, "I understand!" I think that even the Soviets hid it from us at the beginning, and it would be the biggest victory for these devices to be here! I understand! ”

Professor Dong Fang thought for a while and said, "I can introduce a few highly skilled veteran workers to come over and help." In addition, you will have to add some personnel to our real room. This CNC machine tool has a computer system, we don't understand this, you have to find experts and technicians in this area! ”

Lin Qiangsheng nodded and said, "Well, I have a candidate, I will do my best to find someone!" ”

Professor Dong Fang and Lin Qiangsheng chatted softly while watching these precision machine tools in the workshop.

There are not only five-axis linkage CNC machining centers in this workshop, but also 5 sets of four-axis CNC machine tools, the so-called five-axis is to have 3 linear coordinates and two rotary coordinate axes, and the four-axis is only one rotary axis. These coordinate axes are machined in coordinated motion at the same time under the control of the CNC system.

Professor Dong Fang introduced to Lin Qiangsheng: "These CNC multi-axis machine tools can complete multi-sided and multi-directional machining in one clamping, which greatly improves the machining accuracy and efficiency of parts!" Depending on the state of the workpiece, the attitude angle of the tool or workpiece can be adjusted at any time, so it is possible to machine all kinds of complex parts! It also avoids tool interference, simplifies tool shapes, reduces tool costs, and makes workholding simpler! ”

Lin Qiangsheng asked Professor Dong Fang: "Professor Dong, what are the difficulties in our imitation of these machine tools?" ”

Professor Dong Fang shook his head and said, "There are so many difficulties that I can't count them!" For example, most of the motors used in these CNC machine tools are servo motors, which we can't build now! ”

"Its hardware and software are not up to now, hardware refers to mechanical materials, processing accuracy, with these CNC machine tools now we have not mastered them, want to use them to make things I don't know when! In terms of software, electromagnetic control theory, control algorithm, this aspect is a system engineering, involving several disciplines, electromagnetic theory, engineering control, computer programming, simply involving all the existing international advanced manufacturing technology. Is it difficult, you say? ”

"Well, what else, you said it all!" Lin Qiangsheng scratched his head, he didn't expect that a small motor was an obstacle, but he also had this preparation, and he knew that even in later generations, China did not fully master the manufacturing technology of advanced motors. Lin Qiangsheng's heart is very wide. He was not afraid of these things, so he continued to ask Dong Fang boldly.

"There is also a CNC system, we lack researchers in this area, and the processing technology and material handling of functional components such as high-power spindles are also shortcomings! The materials and processes are not up to par, and the gap is very big! ”

Professor Dong Fang glanced at Lin Qiangsheng with disdain, shook his head and said, "Young man, do you know why I didn't report these advanced machine tools of yours to my superiors?" That's because I know that even if the state gets these machine tools, it will have to spend huge financial and material resources to study them! I've heard a lot of old guys say that the country's economy is in terrible shape right now. A lot of military projects were abandoned. I think it's right, if you don't give up some useless military projects, how can you concentrate on research?! You can't chew it if you are greedy! ”

Lin Qiangsheng waved his hand and said, "We won't discuss the affairs of the country!" Dong Lao, you said that I asked you to be responsible for the imitation of precision machine tools, can you manufacture CNC machine tools based on these equipment? Even if we can't reach the level of foreign countries for a while, we must have a start! Start with a simple CNC system for the machine! ”

Lin Qiangsheng continued: "CNC system. I have the right candidate, Harbin Institute of Technology has a CNC job. I can ask them for help. In terms of materials, I will set up a material practice room and allocate funds to conduct materials research. ”

After listening to Lin Qiangsheng's words, Professor Dong Fang nodded and said affirmatively: "If the personnel are in place, it is not difficult to make CNC machine tools, and with these equipment, the boss problem will be solved!" ”

Lin Qiangsheng said goodbye to Professor Dong Fang. When it was time to leave, I said a simple hello to Zou Xue. Zou Xue didn't have a chance to talk to Lin Qiangsheng anymore, so she watched Lin Qiangsheng hurriedly leave the research room.

"Zou Xue, you have to seize the opportunity! I've finally met him, and you still don't talk to him! Lin Qiangsheng is really eyeless! Zou Xue's two friends surrounded her and kept talking.

"Don't say that about Master Kobayashi, he's busy too!" Zou Xue said leisurely.

Both girls smiled. Then they all sighed, and one of them was happy in an instant and looked at the clean workshop and said: "But to be honest, the working environment here is really good, clean and hygienic!" I take off my work clothes every day, and I don't have any dust on my body! ”

"I heard that Lin Qiangsheng got these high-end equipment back from abroad, Zou Xue, how can he do that?" Another girl asked Zou Xue curiously.

Zou Xue shook her head with a smile and said, "I don't know!" Ask him for yourself! A few people teased each other a few words, and then Professor Dong Fang shouted at them to start learning mechanical structures, and then immediately arranged for these students to start a large number of drawings.

These people Lin Qiangsheng found to operate CNC machine tools have poor basic knowledge, and even their mechanical drawing ability is not up to par. Except for Zou Xue and the three girls, other guys who don't even know mechanical drawings dare to expect them to understand complex mechanical drawings in the future. Fortunately, they are all young people, with the motivation to study hard and work hard, Lin Qiangsheng also promised high wages and material rewards, in order to live a good life, in order to learn knowledge and master a skill, young people are also struggling.

Dong Fang is still very pleased with the learning energy of these apprentices, and these people selected by Lin Qiangsheng are good.

There is another important reason why Professor Dong Fang did not report to his superiors, that is, he is currently idle, and he really doesn't want to take a back seat again, or be called a cold palace. He clearly knows that the taste is not comfortable, if he reports the situation here to his superiors, then these equipment may no longer let him touch, no matter what kind of relationship Lin Qiangsheng has with the foreigners behind him, if the country really wants to get these advanced precision machine tools, then these high-end equipment will really say goodbye to him, and his qualifications are not enough to participate in the national project!
