"Xiao Yun, why do you have time to come? Let''s see how we can improve the positioning accuracy of our rotary table... "See you later

    Daoyunfei, a busy man, appeared in his office. Situ Heyun hurried to pull Yunfei to the experimental workshop.

    Since the last time Yunfei sprayed that the rotary table they designed was too large, they soon made the whole hydraulic system and electronic circuit system

    The jointly controlled rotary table has been reduced by one third. Although it has not reached the degree that the length and width of cloud Fei are less than 40 cm, liquid

    Pressure workstation and pneumatic workstation together are even as large as a machining center.

    For the military that urgently needs four axis CNC machine tools to carry out some high requirements on geometric tolerance, as long as it can produce a return

    Products in the drawing stage are OK.

    Therefore, when the miniaturization has just been completed and has not been finally completed, and the accuracy is not very ideal, the military can''t wait

    We placed an order for twenty sets.

    For this, Yun Fei scolded Zhao Xingbang when he knew it. That''s shameless. It''s agreed that half of the family will buy it

    For those who have the right to operate, the goods, on the pretext of their heavy production and no time for production, put their own ten sets of rotary worktables and

    The supporting hydraulic and pneumatic workstations were handed over to their own machining factories.

    Placing military production orders to factories controlled by the military is just putting money from the left hand to their right hand. No matter what happens, it is the most important thing

    It was still in the military pocket.

    "What is your positioning accuracy now?" Yunfei was not in the mood to see what rotary worktable, but thought of if his own CNC

    If the milling machine wants to be produced within half a year, it still needs the strong support of these two old goods. In addition, as long as its own CNC milling machine is produced, although

    Can not produce four axis machining centers, but the production of four axis milling machines is also good.

    Four axis CNC milling machine is definitely a big killer in China in this era!

    I forgot about the four axes just now.

    "At present, our rotation accuracy can only be controlled within 0.1 °, that is, six points. In order to achieve the rotation error of 0.01 ° you said, I

    We still have a long way to go. " Situ Heyun said to Yunfei.

    The precision of four-axis rotary positioning needs not only the control of NC system, but also the control precision of hydraulic servo system. however

    Now Sun Lin doesn''t dare to touch the hydraulic chuck at all. After all, they are just getting started in this research. They can only install it on the rotary workbench

    Mechanical chuck of upper bed.

    "I think if it takes several to replace the 8-bit industrial control chip in their dragon CNC system with a 32-bit industrial control chip, with your current hydraulic pressure

    Technical level, should be able to achieve 0.05 ° accuracy. Huashulong CNC is originally designed for three-axis CNC milling machines and machining centers

    Yes, for the four-axis control, it is still very reluctantly. " Dragon CNC is designed by itself. What are the advantages and defects of Yunfei

    This designer is even clearer than Qin Qingshan and others.

    The CNC system used to control the installation of the fourth axis rotary table was transformed in Yunfei''s 91 heavy industry. Although only

    Only one more rotary shaft is controlled than the three-axis machining center, but more than ten 8-bit industrial control chips are added, and the whole system is three points larger than the original

    More than one.

    If you still put it on the machining center as before, there is no way. After all, the imported machining centers are controlled by the PLC control panel

    It doesn''t take up much space. Yunfei finally had no choice but to order tanaliya''s Electronic Research Institute to transform the transformed department

    The system is made into an independent control cabinet, which is used to be placed separately next to the machine tool.

    "32-bit industrial control chip? This is a dream. You know, it is difficult for us to get 16 bit industrial control chips in China, if not Taiwan

    There are several chip manufacturers in the bay. We may not even get 8-bit industrial control chips in China. Look at those TV sets and refrigerator manufacturers

    Most of them still use two or four digit industrial control chips! " Situ Heyun was noncommittal about Yun Fei''s statement.

    How many people in China don''t know about the domestic situation?

    For situ Heyun''s words, Yunfei was equally noncommittal. The corners of his mouth just tilted slightly and replied to his calm expression. Then, since

    The production of 32-bit industrial control chips will give this old guy who has been engaged in electronic circuits all his life a surprise. I hope he won''t be surprised by himself

    The surprise for them is exciting.

    Now, Yunfei has a hand on these two old guys. If these two old guys know they are working on 32-bit industrial control chips, they will end up in the end

    To estimate, it must be like this rotary table.

    There are many state-owned electronic factories, but most of them are producing some backward products. I can''t put every one in the future in vain

    In, hundreds of millions or even billions of dollars of projects were handed over to the state or state-controlled factories. In the end, you won''t get any benefits

    , no one wants to be a wrongdoer all the time.

    Especially this time, the crisis of Jiuyi heavy industry is largely the means of those guys who wanted to rob Jiuyi heavy industry from themselves last time

    , if they know about the project they are working on now, it is estimated that they will rush to Jiuyi heavy industry even more madly.

    Chinese people have one of the worst habits - it''s better to be broken than complete! In China, there are many people who suffer from red eye disease. They can''t get it by themselves,

    No one else can get it. So when those people know that they can''t get the benefits that will be brought by Jiuyi heavy industry, they will definitely bite their teeth and give it to Jiuyi heavy industry

    In the bud.

    In the world of Yunfei, these guys destroyed many promising companies in the 1990s.

    When Yunfei and situ Heyun arrived at the experimental workshop, Sun Lin was directing several nine level assemblies transferred from Zhao Xingbang

    The fitter removed a hydraulic rotary table only half a meter square.

    "You guy, come on, what''s the matter with us old guys?" Sun Lin knew this when he saw that Yunfei and situ came together to find him

    The boy doesn''t go to the three treasures hall without anything. Otherwise, the boy won''t excitedly inform him that the prototype has been produced last time,

    As a result, the boy said nothing about the thing they spent several months working out. In the end, it''s almost a month now, and there''s nothing

    When I came to the experimental workshop again, I didn''t have nothing like before. I came to see myself and situ.

    "Well, Mr. Sun, you seem to be a snobbish man. Why do you let the boy who has been working hard for the second old man

    ”Yun Fei secretly scolded the older and more refined old thing in his heart, and squeezed out a smile.

    "You boy, don''t be too brave. What''s the matter? Just say it directly. You are a teenager, in my nearly 70 year old

    What''s in front of the boss? " Sun Lin knows that Yunfei must have something to do when he comes here this time, otherwise he won''t appear here at this time, you know

    Road, the factory has just started. Yun Fei, a young man who doesn''t have many capable generals, must be in trouble. Coupled with the smile on his face

    Rong is so reluctant, if not clear.

    Hearing Sun Lin''s words, situ Heyun found that Yunfei was different from the past. He couldn''t help patting his head.

    Sun Lin wiped his hands carelessly with the cotton yarn on the workbench, and took Yun Fei to the office at the door of the workshop.

    "Come on, what''s hard to say before us? What happened in your factory? " When he got to the office, Sun Lin put it in the office

    A few guys who were drawing with pencils and rulers drove out, made a cup of tea for themselves with greasy hands, and then looked at Yun Fei seriously

    Asked.

    Yun Fei pinched and didn''t know what to say.

    I left two old guys just to let them be free labor. Now that things have come to an end, I don''t know what to do

    It''s hard to say, especially when you see two old guys with gray hair.

    He knew that if the two old people promised to help themselves, they had to work overtime every day to work out the basic design of a simple CNC milling machine in a month

    Not necessarily. With the temper of the two old people, it is estimated that they eat and live in the office and are light.

    "You boy, you''re still holding it up now. Let go if you fart, or get out..." Sun Lin saw Yun Fei''s sad face and kept looking at him

    He and situ Laohuo turned their faces, but they didn''t say anything. They couldn''t help being angry.

    Yun Fei sighed. He didn''t really want to exploit the two old people who should have lived for a long time, but if he didn''t ask them, he wouldn''t be alone

    It''s hard to rely on the Soviet Union, just the quasi expert level savavsky. These two old guys are immersed in mechanical and electronic aspects

    Life, especially the research direction is still CNC machine tools, which is not comparable to savavsky.

    "You mean, you want me and situ to help you preside over the research of CNC milling machines and even machining centers?" After listening to Yun Fei, I''m not for nine

    After a description of the current situation of heavy industry, the faces of the two old guys became ugly.

    The current domestic investment environment is really too bad. Those people are too bad!

    "Yes, although the engineers from the Soviet Union are mechanical, they are not people in the direction of CNC machine tools, so they are engaged in design

    When planning, it has great limitations. I''d like to ask the two old people for help. Only if we get out the CNC milling machine in a short time will the dilemma faced by 91 heavy industry be solved

    readily solved. Dissatisfied with you two, I''m almost out of money now... "Yun Fei nodded heavily and said to the two elders.

    "Didn''t you borrow $30 million from the bank? You brought back more than ten million yuan from Huadu. It''s useless so soon? " Although it''s just research

    Yes, but for tens of millions of huge money to spend so fast, the two old guys are also taking a breath.
