"That's okay, just trouble Deputy Director Yun to introduce us to ......" After getting Qin Qingshan's affirmation, Zhao Hui smiled at Yun Fei.

"As for the parameters of that system, I think Mr. Qin has already told you, so I won't say more here. Let's talk about the structure of this system and some of its functions. Yun Fei paused, glanced around the conference room, shook his head, and asked a few people.

"Do you have anything like a chalkboard here that you can write on? If you can't draw a simple diagram or an assembly structure diagram, it's more difficult to say......"

"There is one in the office of the Technical Department below, I'll go get it......" Liang Qiang said that Yun Fei wanted to use the picture to explain to a few of his people, but he was suffering from the lack of a blackboard, so he hurriedly rushed out of the office. After Qin Qingshan said the parameters of this system in Yun Fei's hands, his soul was hooked by this system.

Soon, Liang Qiang entered the conference room with a small blackboard more than one meter long and about sixty centimeters wide, but found that there was no shelf in the conference room that could support the small blackboard.

"You should know better than me that a CNC system is not just a system used to control the machine tool. A complete system consists of three parts: control system, servo system and position measurement system. Of course, the core is the control system. The system in my hand, compared to the system you are designing now, is not only more structurally perfect, more reasonable in design, but more importantly, more powerful in function......"

Yun Fei said as he drew a sketch of the structure of the system on the small blackboard behind him. Although it is a simple diagram, it is clear at a glance where the various functional components are, especially the connection and location of the industrial control chip, the addition of the memory, the control path of the servo system, the placement of the core components of the position control unit and the logic unit of the programmable controller, all of which are clear at a glance on the diagram.

Let the few people who didn't see Yun Fei's design details nod.

A brief general diagram shows whether the system is structurally sound or not.

"In fact, this system is not very different from foreign systems, the biggest difference is that it combines the small plate structure of the American Dynapath system and the large plate structure of the Japanese FANUC system. This not only improves the reliability of the system, but also makes the electronic unit in the vulnerable part of the small board structure, which makes the board more convenient. Of course, the motherboard of this system cannot be purchased abroad, and we have no electronics factory in China that can do it, which I don't know very well now...... "Yun Fei's year in Qingfeng Machinery, in addition to managing factory affairs and plagiarizing this system, he really didn't inquire about the outside world.

For the strength of domestic electronics factories in the nineties, he really doesn't have a little bottom in his heart.

If nothing else, let's just say that the industrial control chip he transformed from Intel's 51 series chips, even if there is no way to produce it in China, he doesn't dare to take this abroad to find a foundry that can produce it. Let Intel know that there will be endless troubles. After all, the set of chips he designed has too strong a shadow of 8051.

This is also a matter of no way, who called the entire Chinese single-chip microcomputer research in later generations, and the 51 series occupied the mainstream position! Yun Fei was originally a halfway monk, if it weren't for Du Niang seeing a lot of various types of industrial control chips, he would even plagiarize Intel's 8051 or 8031 as it is, anyway, they now have a monopoly on this type of chip for China.

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

They have been engaged in CNC systems for so many years, and have been imitating foreign CNC systems, but they have not succeeded, let alone have their own design ideas and concepts. Now their company is only engaged in this set of control systems 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 that Qin Qingshan, who has always been disobedient to others, lost his soul after seeing Yun Fei's system at the beginning. If Huashu can't come up with a system that can compete with this system, the system that Huashu is designing now will not be recognized by the market at all. As soon as it goes public, it will be abandoned by the whole market, although it is still a seller's market. No one wants to be stupid enough to leave a more functional system and use a system with all sorts of flaws.

Especially those factories that buy CNC systems to transform ordinary machine tools for precision machining, if they have a choice, they will definitely not buy a set of expensive systems that cannot compensate for thread clearance and have no macro program functions to modify machine tools.

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

The imported systems are classified according to the use, and the parameter settings define the function or something, and his system can be said to be a set of system assembly. After production, as long as a few circuit boards are added, or a few circuit boards are reduced, and then some are added or reduced when defining the function, it becomes a different control system for lathes or milling machines.

"Deputy Director Yun, we are a little difficult to understand what you said, especially the combination of large and small boards, without practice, what is the function, and the control accuracy cannot be guaranteed......" Zeng Hongqi said to Yun Fei, which is a little difficult to digest.

After all, although he has also been engaged in CNC system research for so many years, after all, it can't be compared with Qin Qingshan and Liang Qiang, the two old houses of technology, and it is estimated that Zhao Hui is not much better. What he needs to do now is to find out the faults in Yun Fei's system, and then bargain.

"I can't prove this. If a complete set of samples were placed in front of you, I think you would definitely beg me for terms without saying a word. Of course, with the sample, there is nothing for you to do, and at that time, it is not what you can get from 49% of the shares of a company with a registered capital of 10 million plus 10 million cash! ”

How could Yun Fei not understand Zeng Hongqi's thoughts? So the speech is a little unpolite, and the tone is extremely cold. His words made Zeng Hongqi feel that it was not in the subtropical April of the Pearl River Delta, but in April in Siberia.

"Deputy Director Yun, we all understand the value of your system. However, this is only a system that is still in the theoretical stage, it has not been tested, and no samples have been produced, so your asking price is a little too high? Zhao Hui saw Yun Fei put down the chalk in his hand and sat down, knowing that he would never talk about the techniques of this system now. So he began to enter his role, and began to discuss the price through the topic of Zeng Hongqi and Yun Fei.

The simple diagram that Yun Fei drew on the blackboard, they could all understand it, especially Yun Fei while drawing, and explaining the various unit wiring arrangements and control methods. They didn't expect that Yunfei's system would actually add a displacement detection unit.

At present, the domestic CNC research is still in the bottleneck, most of the research is in the study of the open-loop control system, the whole system has no feedback elements, the accuracy of the control depends on the accuracy of the motor and the screw rod. At present, the servo motor in China is still blank, and most of them are simple numerical control systems that study the power stepper motor as an actuator. Therefore, many people are ignorant about the use of servo motors, and they have no experience at all, where will they dare to design to the CNC system.

Yunfei's system not only uses servo motors, but most importantly, it has a displacement detection device. The person who designed the system came up with the idea of installing a displacement detection device at the end of the drive screw to indirectly measure the actual position of the actuator. In this way, in CNC machine tool processing, not only can the machining accuracy be effectively controlled, but it is 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 that Huadu CNC is now researching and designing, and the CNC system without feedback device can be compared.

"Hehe, this price is high? So how much do you think is the right price? Yun Fei heard Zhao Hui's words, but he was happy.

These guys who didn't appear in their own world were really not fuel-efficient lamps, and they hadn't officially entered the negotiations yet, so they actually began to lower prices.

When Yun Fei slandered Zeng Hongqi and Zhao Hui in his heart, he never thought that these guys would have to be forced by him to do not follow common sense, or even learn from him. As soon as he was called, he began to put pressure on Huadu CNC, a few guys who were several rounds older than him!

"During this time, we have also discussed many times that your system, how many shares we should give you, and how much cash is appropriate. Although we didn't see the design drawings today, but listening to your explanation, we also understand that this system is indeed relatively high-end in China, and at least it can compete with some of the poorer mid-range systems exported to our country abroad. You see, how about six million in cash, 20 percent of the shares? After all, this system still needs to wait for the production to be produced, and after countless tests, it will be able to know whether the design data can be achieved...... "Zhao Hui directly offered Yun Fei.

The reserve price they discussed, the cash did not decrease much, and the shares were reduced ruthlessly. After all, Yunfei's asking price is 10 million in cash and 49 percent of the shares.

Everyone knows that with this system, what is worth 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 Yun Fei, more than 100 sets can be sold for 10 million!
