Zhao Hui went to get the contract, but he couldn''t get it right for a while. Qin Qingshan has many doubts about the system in Yunfei''s hand, and Liang Qiang is more positive and looking forward to it.

    At the urging of the two, Yunfei went to his car, took the drawing to the office and began to explain it in detail to several people.

    Now that the cooperation consensus has been reached, the equity transfer contract will be signed immediately. With an attitude of being responsible for himself, Yun Fei explained to several people in great detail this time. The various functions of the system were explained to several people separately. After Zhao Hui got the contract out, he only explained the structure of the PLC programmable controller of the NC system. He still didn''t take out the drawings of the single chip microcomputer.

    For this system, the 8-bit single chip microcomputer based on Intel''s 51 series kernel produced by many companies in Taiwan is fully competent. Taiwan has built many factories in mainland China these years. They do not exist to block technology in Chinese mainland like Europe and America.

    "For the problem of single chip microcomputer, I hope you don''t get too tangled. For Chinese mainland, foreign control is only 16 high-end products. For eight place 8051 control is not too strict, four of 8031 now how many. However, in the key parts of this system, the control ability of 8031 is not enough. At least 8051 or single chip microcomputer of the same grade is required. " When Yunfei talked about the control structure of the CNC system he copied, Qin Qingshan asked anxiously what model the MCU should choose.

    Yunfei originally copied some single-chip microcomputer synthesis of later generations, in addition to a set of most practical control chip design drawings. But at this time, he was even more afraid to take out his set of chip design drawings.

    In China, the research on single chip microcomputer has just started. If he pushes this achievement to those old men, it is estimated that there will be a problem.

    It''s reasonable for some old men to engage in numerical control research. After all, China has successfully developed numerical control machine tools in the late 1950s. If those old men have the energy and conditions to engage in computer hardware while engaging in CNC machine tools or CNC systems, he doesn''t believe it. If the old men really have this ability, they will be recruited back by the state in the first time after the great turmoil.

    Computers, in the late 1970s and early 1980s, could hardly find a few talents.

    "Single chip microcomputer, there are two structures on the market. Centralized instruction CISC and reduced instruction RISC. CISC structure, also known as von Norman structure, time-sharing multiplexing of data lines and instruction lines, rich instructions and powerful functions. However, it is precisely because of its structure that instruction and data can not be taken at the same time. The control speed is limited when the single chip microcomputer with this structure is used as the industrial control chip of the NC system. Moreover, the single chip microcomputer with this structure has one of the biggest disadvantages - the price is too high. Any good piece will cost several dollars or even tens of dollars. Even so, our system still has to use the single chip microcomputer with this structure as the control core, because the operation relationship of NC machine tool in the operation process is very complex, especially the simultaneous linkage of several axes. " Yun Fei found that these guys who engage in CNC system don''t seem to know much about these most basic things.

    Where did he know that those who engage in CNC systems in China are not like him, a guy from later generations, who has the ultimate artifact like Du Niang. As long as there is something he doesn''t understand, tell Du Niang, Du Niang will show countless results and even things he wants to relate.

    In the past, it was difficult to get an 8031 chip for domestic research in this field. There was no way for all researchers to understand it in detail.

    "...." several people who listened to him eagerly stared at Yun Fei.

    "Shit, you beat us... Our system can use not only Intel''s 8051 series, but also Taiwan Huabang W78, which I think is more suitable for our system. I won''t worry about getting stuck in the future, and the price is relatively cheap. Of course, the quality can''t be compared with that developed by the guy who grew up eating raw beef. However, this is acceptable to our domestic users. "

    Yun Fei felt that he couldn''t find anything more tired than explaining these things to a few and a half old men in his two lives. If it were not for the soul to the body, many things he browsed on the Internet in the original world would appear as long as he thought of keywords. He didn''t know what to do.

    After a while, Yun Fei was exhausted. After all, he was not very familiar with these things. He is familiar with the structure of machine tools and the operation of machining technology. CNC system, just know something. It''s really hard to fool these old professional things with these things you know.

    Qin Qingshan and Liang Qiang listened with straight eyes, while Zeng Hongqi was sleepy. Yunfei took out a cigarette and handed it to Zeng Hongqi and Liang Qiang, one for each. Regardless of them, he leaned back on the back of his chair and rested. Qin Qingshan doesn''t smoke. Yun Fei already knew.

    "Factory director Yun, we are using Huabang''s chips now. Can we use this set of machine tools that can control three-axis linkage?" Qin Qingshan digested the things Yunfei said just now. Seeing that Yunfei was about to fall asleep, he asked Yunfei eagerly. They used to assemble systems and various accessories from all over the world. As long as they can get them, be compatible, put them together and make the system run, they will be very grateful.

    Now lsk9201 can no longer mess around like the systems they have assembled. If its reputation is ruined, it will not only be sorry for the old people who have struggled for this system for 30 years, but also for the 40% shares they lost.

    It can be said that Yunfei''s system allows him to see another world, and the things Yunfei is talking about now seem to be the key to open the door he looks at but can''t touch.

    Qin Qingshan didn''t think about where Yun Fei came from. He took it for granted that Yun Fei knew these things. The other two also didn''t have any unexpected feelings. Originally, Yunfei was worried that he talked too much and couldn''t explain where he came from. After all, Yunfei knows more about these things produced abroad than Qin Qingshan. Now he doesn''t want to say more. If he says too much, he will always show his feet.

    "Lao Qin, Mr. Yun, the contract has been completed. Let''s have a look first..." just at this time, Zhao Hui came in with a printed contract.

    The contract is very simple. It states that Yunfei exchanged lsk9201 for 40% of the shares of Huadu CNC Equipment Co., Ltd. and 12 million in cash. Yunfei doesn''t interfere with the company''s daily operation, just be a technical consultant and wait for the year-end dividend

    Qin Qingshan took the contract, read it and then handed it to Zeng Hongqi and Liang Qiang. Finally, after they determined that there was no problem, they seriously signed his name as the boss. Yun Fei carefully read the contract word by word and found that the contract was written in detail, although it could not be compared with the commercial contract samples he saw online. This three page contract was very clear about the responsibilities and obligations of both parties. He mentioned the pen handed over by Zhao Hui and signed his name under the eyes of several people.

    Yun Fei left, leaving a thick pile of drawings, taking away two million cash checks from ICBC and 40% equity of Huadu CNC. For the remaining 10 million cash, the contract clearly stipulates that Yunfei must assist Huadu CNC to completely produce the system. When the lsk9201 sample is produced and can achieve more than 70% of the function of the drawing design, the equity transfer contract will take effect, and pay the remaining 10 million cash to Yunfei at the same time.

    In other words, what Yunfei gets now is equivalent to a deposit.

    Yunfei doesn''t care much about this. After all, the drawings have indicated how to select various hardware of this CNC system. If it takes a few months, Yunfei will have a headache whether he has chosen the wrong partner.

    This world is no longer his original world, and the number of flowers is not the number of flowers that the original world and foreigners are in the tripartite confrontation. Even if there is a problem, the number of flowers can not produce the simplest lathe control system in a short time, Yunfei can only admit bad luck.

    Who told him to measure the present world from the perspective of his original world!

    Yunfei refused to spend several shareholders to stay for dinner and celebrate. He now needs to go to Jimin hospital to see his uncle, and then Huixin Kaixing. It is estimated that Ren Zhiguo is flirting with his secretary and scolding himself and Wang Qingfeng.

    After Yun Fei left, Qin Qingshan began to study the drawings left by Yun Fei in detail. They must study this set of drawings thoroughly in the shortest time, and then produce samples. After the test, they will bring the system to the market.

    After all, now several of them are carrying 12 million loans from ICBC, especially Qin Qingshan. According to his original share of shares, one person accounts for nearly 9 million loans. If he can''t get the system listed and put it on the market in time, the annual interest of 10% will be enough to give him a headache. If he is in debt, he won''t expect to work out the numerical control system again.

    Now it''s early April. Qin Qingshan discussed with several people that we must complete all kinds of tests of lsk9201 before September, and then we can seize the opportunity to appear at the Huadu fair, which may save a lot of promotion expenses.

    Of course, Yunfei just suggested that the first set of C series system for lathe should be developed first according to the drawings, so as to facilitate the return of funds. Qinqingshan several people want to get out the C series lathe system and X Series milling machine system at one time. After all, they have also produced nearly 100 sets of CNC systems. They know that the assembly system is very simple. The only complex thing is to input the setting of various functional parameters and the PLC ladder logic control program for various controls.

    The PLC ladder program has been left in the c-series lathe system, and the X-Series milling machine system ladder program is not difficult to do. After all, it is too long. It is far from as easy as he was to compile the ladder program of the simple system of Wang Qingfeng''s second-hand milling machine.

    If Yunfei has a four-axis machining center without ladder program in front of him, Yunfei can only stare.
