Smart Industrial Empire

"That's fine, please let Deputy Factory Manager Yun introduce us..." 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 just talk about the structure and some functions of this system." Yun Fei paused for a while, and in the conference room He glanced around, shook his head, and asked a few people.

"Do you have something like a small blackboard here that you can write on? If you can't draw some schematic diagrams or assembly structure diagrams, it will be more difficult to say..."

"It's in the office of the technical department down there, I'll get it up..." Liang Qiang rushed out of the office because he didn't have a blackboard because he wanted to use pictures to explain to Yun Fei.After Qin Qingshan mentioned the parameters of this system in Yun Fei's hands, his soul was hooked by this system.

Soon, Liang Qiang carried a small blackboard that was more than one meter long and about [-] centimeters wide into the meeting room, but found that there was no shelf in the meeting room that could support the small blackboard, and finally went to the adjacent office After moving a desk, the small blackboard stood up against the wall on the desk.

"Everyone should know better than me that a CNC system is not just a system used to control machine tools. A complete system consists of three parts: 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 not only has a more complete structure, but also a more reasonable design, and is more important. Yes, more powerful..."

While talking, Yun Fei drew a simplified structure diagram of the system on the small blackboard behind him.Although it is a simplified diagram, the location of various functional components is clear at a glance, especially the connection and location of the industrial control chip, the addition of memory, the control path of the servo system, the position control unit, the logic unit of the programmable controller, etc. The placement of core components is clear at a glance on the sketch.

Those who hadn't seen Yunfei's detailed design all nodded their heads.

A simple general picture can tell whether the system structure is complete or not.

"This system is actually not very different from foreign systems. The biggest difference is that it combines the small board structure of the American dynapath system and the large board structure of the Japanese fanuc system. This not only improves the reliability of the system, but also The electronic unit in the vulnerable part adopts a small board structure, which makes the replacement of the board more convenient. Of course, it is impossible to purchase the main board of this system abroad. Is there any electronic factory in our country that can make it? I am not very sure about this yet. Clearly..." During Yun Fei's one-year stay at Qingfeng Machinery, apart from managing factory affairs and plagiarizing this system, he really hadn't inquired about the news from the outside world.

Regarding the strength of domestic electronics factories in the 90s, he really didn't have any idea.

Not to mention anything 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 dare not take it abroad to find a foundry that can produce it. .Let Intel know, there will be endless troubles.After all, the set of chips he designed has too strong a shadow of 8051.

This is also something that can't be helped. Who told the whole of China's single-chip microcomputer research in later generations, the 51 series has occupied the mainstream position!Yun Fei was originally a monk. If he hadn’t seen a lot of various types of industrial control chips through Du Niang, he would even have copied Intel’s 8051 or 8031. Anyway, their current type of chip is monopolized by China. .

Yunfei's explanation made all the old guys who have been engaged in the research of numerical control system for decades fall into deep thought.

They have been engaged in CNC systems for so many years, and have been imitating foreign CNC systems, but they have not been successful, let alone have their own design ideas and concepts.Now the set up by their company is only used for the control system on the CNC lathe, which can be said to be extremely crude, especially before Yunfei's system diagram and Yunfei's description.

Now they understand why Qin Qingshan, who has always been dissatisfied with others, lost his mind after seeing Yun Fei's system for the first time.If Huashu cannot come up with a system that can compete with this system, the system Huashu is designing now will not be recognized by the market at all.Once listed, it will be abandoned by the entire market, although it is still a seller's market.No one wants to foolishly leave a system with more complete functions without using a system with various defects.

Especially those factories that purchase CNC systems to modify ordinary machine tools for precision machining, if they have a choice, they will never buy an expensive system to modify machine tools with a system that cannot perform thread clearance compensation and has no macro program functions.

"Actually, the biggest advantage of this system is that it can not only control CNC lathes, but also CNC milling machines. The only difference is that when setting system parameters, set various functions, action states, and frequently used values. It’s just different. It’s not so much one system, but two systems. When the system is used for milling, we can call this system the x-series; when the system is used for turning, we call it the c-series. Because customers have different needs and many functions are not available, we have to classify our system according to the needs of customers. In this way, not only will we have more product models, but customers will also reduce some of the systems they don’t like because of the system. Needed functions and less money..." Yun Fei talked about the biggest difference between his own system and the imported system.

Imported systems are classified according to usage, parameter settings define functions, and his system can be regarded as a system assembly.After production, just add a few circuit boards, or reduce a few circuit boards, and then add or reduce some when defining functions, and it becomes a different control system for lathes or milling machines.

"Deputy Director Yun, it's hard for us to understand what you said, especially the combination of large and small boards. Without practice, there is no way to guarantee the function and control accuracy..." Zeng Hongqi said to Yunfei These are a little hard to digest.

After all, although he has also been engaged in the research of CNC systems for so many years, he cannot compare with Qin Qingshan and Liang Qiang, two technical old houses, and it is estimated that Zhao Hui is not much better.All he needs to do now is to find out what is wrong with Yunfei's system, and then bargain.

"For this, I can't give a proof. If there is a complete set of samples in front of you, I think you will definitely ask me to make a condition without saying a word. Of course, with the samples, there is nothing for you, that At that time, it is not what you, a company with a registered capital of 1000 million, can get 40.00% of the shares plus 1000 million in cash!"

How could Yun Fei not understand Zeng Hongqi's thoughts?That's why he spoke a little impolitely, with an extremely cold tone.His words made Zeng Hongqi feel that he was not in the subtropical April of the Pearl River Delta, but 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. Is your asking price too high? Seeing Yun Fei put down the chalk in his hand, Zhao Hui sat down, knowing that he would never talk about the technology of this system now.So I started to enter my role, and started to discuss the price through the topic of Zeng Hongqi and Yun Fei.

They could understand the sketches drawn by Yunfei on the blackboard, especially when Yunfei was drawing while explaining the arrangement of various unit circuits and control methods.They didn't expect that Yunfei's system actually added a displacement detection unit.

At present, domestic numerical control research is still a bottleneck. Most people's research is on open-loop control systems. The entire system has no feedback components, and the control accuracy depends on the accuracy of the motor and screw.At present, the servo motor is still a blank in China, and most of them are simple numerical control systems that study power stepping motors as actuators.Therefore, many people are ignorant about the use of servo motors, and have no experience at all. How can they dare to design it on the CNC system.

Yunfei's system not only uses servo motors, but also has a displacement detection device most importantly.The person who designed this system actually thought of installing the displacement detection device at the end of the drive screw to indirectly measure the actual position of the actuator.In this way, in the machining of CNC machine tools, not only can the machining accuracy be effectively controlled, but also it is easy to debug.At the same time, such a system will have better stability during operation.

It is far from being able to compare with the open-loop control system that Huadu NC is currently researching and designing, the kind of NC system without feedback device.

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

These guys who didn't appear in my own world are really not fuel-efficient lamps. They have not officially entered the negotiation yet, and they have started to lower the price.

When Yun Fei was slandering Zeng Hongqi and Zhao Hui in his heart, he never thought that he had to force these guys to act unreasonably, or even learn from him.Who told him to start putting pressure on Huadu NC who were several rounds older than him as soon as he came!

"During this period of time, we have also discussed many times. How many shares and how much cash should we give you for this system of yours? Although we didn't see the design drawings we believed in today, we understand it after listening to your explanation. This system is indeed relatively high-end in China, at least it can compete with some relatively poor mid-range systems exported to our country from abroad. Look at this, how about 600 million in cash and 20.00% of the shares? After all, this system , still need to wait for the production, and after countless tests, we can know whether the design data can be achieved..." Zhao Hui directly asked Yun Fei for a price.

The base price they negotiated, the cash did not decrease much, but the shares were greatly reduced.After all, Yunfei's asking price is 1000 million in cash and 40.00% of Jiu's shares.

Everyone knows that with this system, what is valuable is not the 1000 million cash, but the shares of the company that produces and sells this system!If this system can realize all the functions proposed by Yunfei, more than 100 sets can be sold for 1000 million!
