(a book recommended by a friend, the introduction to the cultivation of all-round local tyrants, tells a story of * * silk growing into a local tyrant.)

    "That''s OK. Please ask deputy factory director Yun to introduce us..." after Qin Qingshan''s affirmation, Zhao Hui smiled at Yun Fei.

    "I think President Qin has told you about the parameters of that system. I won''t say more here. Let''s talk about the structure and some functions of this system. " Yun Fei paused, scanned around the conference room, shook his head and asked several people.

    "Do you have a small blackboard or something you can write on? If you can''t draw some sketches or assembly structure drawings, it''s difficult to say... "

    "There are some in the office of the technology department below. I''ll get them..." Liang Qiang had to explain Yun to several people with a picture, but he hurried out of the office because he didn''t have a blackboard. After Qin Qingshan said the parameters of Yunfei''s system, his soul was hooked by the system.

    Soon, Liang Qiang came into the conference room with a small blackboard about one meter long and 60 cm wide. However, he found that there was no shelf in the conference room that could support the small blackboard. Finally, he went to the next office to move a desk, and then let the small blackboard stand on the desk against the wall.

    "You should know better than me that a set of CNC system actually does not simply refer to the system used to control the machine tool. A complete system consists of control system, servo system and position measurement system. Of course, the core is the control system. Compared with the system you are designing now, the system in my hand is not only more perfect in structure, more reasonable in design, but also more powerful in function... "

    Yun Fei said, drawing a brief structure diagram of the system on the small blackboard behind him. Although it is a schematic diagram, the location of various functional components is clear at a glance, especially the connection and location of industrial control chips, the addition of memory, the control way of servo system, and the placement of core components such as position control unit and programmable controller logic unit.

    Several people who didn''t see Yunfei''s design details nodded endlessly.

    A brief general drawing can show whether the system structure is perfect or not.

    "In fact, this system is not very different from foreign systems. The biggest difference is that it combines the small board structure of American Dynapath system and the large board structure of rbfanuc system. This not only improves the reliability of the system, but also adopts a small board structure in the electronic unit at the vulnerable part, which makes the replacement of the board more convenient. Of course, the motherboard of this system can''t be purchased abroad. I''m not sure whether there are any electronic factories in China that can do it... "Yun Fei''s year in Qingfeng machinery, in addition to managing factory affairs and copying this system, he really hasn''t heard from the outside world.

    For the strength of domestic electronic factories in the 1990s, he really has no bottom in his heart.

    Not to mention anything else, he said that the industrial control chip he transformed from Intel''s 51 series chips, even if it can''t be produced in China now, he didn''t dare to take it abroad to find a foundry that can produce it. Let Intel know that there will be endless trouble. After all, the chip he designed has too strong shadow of 8051.

    This is also a matter of no way. Who calls the whole Chinese single chip microcomputer research in the future? 51 series has occupied the mainstream position! Yunfei was originally a monk. If he hadn''t seen a lot of various types of industrial control chips through Du Niang, he would even copy Intel''s 8051 or 8031 as it is. Anyway, they now monopolize this type of chips in China.

    Yun Fei''s explanation made a group of old guys who have been engaged in numerical control system research for decades fall into meditation.

    They have been engaged in CNC systems for so many years and have been imitating foreign CNC systems, but they have never succeeded, let alone have their own design ideas and ideas. Now the control system that their company has developed is only used for CNC lathes, which can be said to be extremely simple, especially before the system diagram of Yunfei and the description of Yunfei.

    Now they understand why Qin Qingshan, who has been disobedient to others, lost his soul after seeing Yunfei''s system at the beginning. If Huashu can''t come up with a system to compete with this system, the system designed by Huashu can''t be recognized by the market at all. Once listed, it will be abandoned by the whole market, although it is still a seller''s market. No one wants to use a system with various defects instead of a more functional system.

    Especially those factories that buy CNC system to transform ordinary machine tools for precision machining, if they have a choice, they will never buy a set of expensive system that can not compensate thread clearance and has no macro program function to refit the machine tools.

    "In fact, the biggest advantage of this system is that it can not only control the NC lathe, but also control the NC milling machine. The only difference is that when setting the system parameters, it sets various functions, action states and frequently used values. It is not so much a system as two systems. When the system is used for milling, we can set the system as X series; When the system is used for turning, we set it as C series. Because customers have different use needs and many functions are not available, we must classify our system according to customers'' use needs. In this way, not only do we have more product models, but customers will also spend less money because the system reduces some functions they don''t need... "Yunfei said the biggest difference between his own system and the imported system.

    Imported systems are classified according to use, and parameter settings define functions. His system can be regarded as a system assembly. In production, as long as several circuit boards are added or reduced, and then some or less are added or reduced when defining functions, it becomes a different control system for lathes or milling machines.

    "Deputy factory director Yun, it''s a little difficult for us to understand what you said, especially the combination of large and small boards. There is no way to guarantee the function and control accuracy without practice..." Zeng Hongqi said to Yun Fei, which is a little difficult to digest.

    After all, although he has also done research on CNC system for so many years, after all, he can''t compare with Qin Qingshan and Liang Qiang. It is estimated that Zhao Hui is not much better. What he needs to do now is to find out the problems of the cloud non system, and then bargain.

    "I can''t prove this. If there is a complete set of samples in front of you, I think you will definitely ask me for conditions without saying a word. Of course, with the samples, there will be nothing for you. At that time, you could not get 49% of the shares of the company with a registered capital of 10 million plus 10 million cash! "

    How can Yun Fei not understand Zeng Hongqi''s mind? So he was a little impolite and his tone was very cold. His words made Zeng Hongqi feel not in the subtropical April of the Pearl River Delta, but in Siberia.

    "Deputy factory director Yun, we all understand the value of your system. But this is just a system that is still in the theoretical stage. It has not been tested and no samples have been produced. Is your asking price too high? " Zhao Hui saw Yunfei put down his chalk and sat down. He knew that he would never talk about the technology of this system now. So he began to enter his own role and began to discuss the price through the topic of Zeng Hongqi and Yun Fei.

    They can see the sketch drawn by Yun Fei on the blackboard. In particular, Yun Fei explains the arrangement of various unit lines and control methods while drawing. They didn''t expect that a displacement detection unit was added to the non cloud system.

    At present, the domestic NC research is still a bottleneck. Most people''s research is on the open-loop control system. The whole system has no feedback components, and the control accuracy depends on the accuracy of motor and screw. At present, servo motor is still a blank in China, and most of them study the simple CNC system of power stepping motor as actuator. Therefore, many people are ignorant about the use of servo motors. They don''t have any experience at all. Where would they dare to design CNC systems.

    Yunfei''s system not only uses servo motor, but also has displacement detection device. The designer of this system actually thought of installing the displacement detection device at the end of the transmission screw rod to indirectly measure the actual position of the executive parts. In this way, in the machining of NC machine tools, it can not only effectively control the machining accuracy, but also easy to debug. At the same time, such a system will be more stable during operation.

    It is far from the open-loop control system studied and designed by Huadu CNC, which can be compared with the CNC system without feedback device.

    "Hehe, is the price too high? How much do you think is appropriate? " Yun Fei was happy when he heard Zhao Hui''s words.

    These guys who didn''t appear in their own world are really not fuel-efficient lights. They started to lower the price before they officially entered the negotiation.

    Yun Fei never thought that these guys would have to be forced by him or even learn from him if they didn''t follow the common sense. Who told him to come and start putting pressure on Huadu CNC, who are several rounds older than him!

    "During this period, we have also discussed many times. How many shares and how much cash should we give you for your system. Although we didn''t see the design drawings we believe in today, we also understand from your explanation that this system is indeed relatively high-end in China. At least it can compete with some poor medium-sized systems exported to our country from abroad. You see, how about six million in cash and 20% of the shares? After all, this system still needs to be produced. After countless tests, we can know whether it can reach the designed data... "Zhao Hui directly asked Yunfei for a price.

    The reserve price they discussed did not decrease much in cash, and the shares could be reduced ruthlessly. After all, the non asking price of cloud is 10 million cash and 49% shares.

    Everyone knows that with this system, the value is not the 10 million cash, but the shares of the company that produces and sells this system! If this system can realize all the functions proposed by the cloud, more than 100 sets can be sold for 10 million!
