Intelligent Industrial Empire

Yun Fei hates that he did not learn computer programming, or he would set up a software company to pirate those classic Microsoft operating systems, not to mention bankrupting Microsoft. At least, the richest man in the world in the future will be somebody, not Bill. Old stuff.

"Xiaoyun, the machining center tool magazine in the laboratory will have its first experiment tomorrow. Do you think you have time to go to the site to check it out?" Yun Fei was wandering around the sky, not even noticing that it was about to get off work.

The appearance of Wu Zhongda made Yun Fei's already good mood even more refreshing.

The military provided not only electronic personnel, but knew that Yunfei lacked many experienced professional and technical personnel in mechanical and hydraulic and pneumatic fields. It proactively provided Yunfei with dozens of them in some of their factories and research institutes. Technical engineer.With the addition of these people, the team efficiency of Situ Heyun and Sun Lin instantly improved.Most of those who joined in are over forty, but they are not comparable to the young graduate students they bring.

Yun Fei also knew the purpose of the military.

Because the country’s development focus is on the economic field, the military invests very little in military equipment. The military expenditure is not much. In addition to raising millions of standing troops and updating some really old weapons and equipment, they have to For some of the most money-burning fields such as aerospace and aviation, which are related to the entire defense industry, invest in research funds, and there is no excess funds to invest in some ordinary conventional weapons and equipment.

Without the investment of research funds, the large number of military research teams can only be left idle with wages.This is not only a serious waste, but also a sad thing for technical engineers who have no research projects.

The entry of military researchers into the research department of Jiuyi Heavy Industry is a win-win cooperation for both parties.Those grass-roots researchers in the military can maintain their research status at Jiuyi Heavy Industry, and will not gradually degenerate in research capabilities; and Jiuyi Heavy Industry has solved the problem of the lack of scientific research teams.

Of course, it is impossible for these researchers to serve Jiuyi Heavy Industry forever. As long as the stalled projects of the military are started again, these researchers belonging to the military will all be withdrawn from Jiuyi Heavy Industry and return to their units.Fortunately, Yunfei signed a five-year scientific research contract with the military represented by Zhao Xingbang.Within the scope of the contract, even if these military researchers want to withdraw, they must contact the Jiu Yi Heavy Industry and Commerce Group in advance. These are all written in the secret contract in white and black.

In the environment where a large number of state-owned enterprises went bankrupt, these military technicians and engineers were well placed. The cooperation with Jiuyi Heavy Industry has explored a brand-new cooperation model, which is also in the domestic economic situation. For the better, when the country gradually began to vigorously develop its armaments, the military’s high-precision and sophisticated weapons and equipment experienced a blowout within a period of time.This is something to come, close to the subject.

As soon as he went to work the next day, Yun Fei entered the mechanical test workshop of the scientific research building.

The development and test stages of various equipment of Jiuyi Heavy Industry are all in this test workshop.

"Lao Sun, how? Are you sure you can do it all at once?" The damn weather, getting hotter and hotter, without central air-conditioning, only powerful fans whistling in the test workshop, in time for the early morning just to work, also makes people feel Not much cooler.

"Do you think this is a test of ordinary machine tools? You can do it again, you kid, anyone who knows understands that you are a bit eager to see the machining center you produce on the market; if you don't know, you think you After the kid got a CNC milling machine in the company, his confidence skyrocketed and he became arrogant..." Sun Lin gave Yunfei a white glance.

This kid, although he has not come to the mechanical test workshop during this time, even if he goes upstairs in the electronic research laboratory, he will not enter it. He doesn't know what he is thinking about. Sometimes he encounters some problems. If I want to talk to this kid, I can't find anyone.

"I have confidence in you!" Yun Fei smiled wryly.

"This is not a CNC milling machine. Although we have been doing it for so many years, we have been successful, but the positioning accuracy problems are not so easy to solve." Situ Heyun said seriously to Yun Fei on the side.

"That's right, you kid don't want to think about it. Let's talk about the simple hat-style tool magazine first. You don't agree, you have to build a complicated disc-style tool magazine when you come up..." Regarding Yunfei's high-rise building method, Sun Lin Very upset.

It was a challenge for him to start from the more difficult places, and it was exactly what he liked.It is also because the disc-type tool magazine is far more difficult than the hat-type tool magazine. When the machine tool magazine is rotated and the tool is changed, the manipulator used to grasp the tool is likely to be unable to grasp the tool. Knife drop phenomenon.

Of course, the phenomenon of tool drop is a problem often encountered by CNC machining centers, which has many factors.Generally, it is guaranteed to be in the range of a few ten thousandths, that is to say, only once or twice in a tool change of 10,000 times, otherwise, this kind of CNC machine tool will not be qualified.

The price of CNC tools is not comparable to that of ordinary tools, especially some customized CNC tools, a 10 mm diameter alloy milling cutter, there may be thousands of dollars, if the tool is dropped during the tool change process and damaged , Who would dare to buy such a machine tool?

These days, the test workshop has been working on this thing day and night. If the hydraulic and pneumatic aspects are controlled separately, there is no problem. Now the entire tool magazine is assembled with the machine tool. This involves many things. Otherwise, China would not have been able to make much progress in CNC machine tools for decades. In the field of high-end machine tools, it relied on imports of high-end machine tools from countries such as Germany, the United States, and Japan.

"This is not a problem. Anyway, what we are doing now is just a test machine. We still have time to gradually improve various problems." The two veterans are more anxious than Yunfei. The development of foreign CNC machine tools is changing with each passing day. China is still at the lowest level. If you want to achieve self-sufficiency on high-end machine tools on the three-axis at the end, it cannot be completed in a short time. It is very likely that they will not see it in their lifetime.

If Yun Fei is not eager, it is false.Several Taiwanese companies engaged in CNC machine tools are seeking to build factories in the mainland during this period.

Taiwan’s Youjia, Taiyu and other factories will build factories in the mainland at the latest in 1995. If the machining center of Jiuyi Heavy Industry does not meet the technical parameters of the CNC machining center they produce, for Jiuyi Heavy Industry, It will be a disaster.

In China, whether it is official or private, there is a blind worship of foreign technology.Everyone believes that the moon abroad is rounder than China. Otherwise, so many high-end talents from China would spend the fees provided by the state to learn, but in the end they would automatically stay in the capitalist world and let the vampire capitalists exploit it.

"Prepare the program, install all the tools, hurry up!" The machine bed is a machining center specially produced by Jiuyi Heavy Industry with an X stroke of 800mm, a Y-axis stroke of 500mm, and a Z-axis stroke of 500mm. The center is the most widely used in China's CNC machining market.

The hydraulic workstation, pneumatic workstation, and tool magazine have been assembled in the first day. The first experiment today is that the machining center after the assembly calls the tool in the CNC tool change code program to perform positioning and positioning under some simple cutting actions. Precision issues.

Under Sun Lin's command, Lin Yajun, who was seconded from Xin Kaixing next to him, skillfully installed various knives, and quickly completed the calibration of each knife in the Z-axis direction.

The tool setting of machining center is much more convenient than the tool setting of CNC lathe. The X-axis and Y-axis directions only need to set the workpiece coordinate system for the parts to be processed. After the tool setting is completed, as long as the part's processing coordinate system is not set separately, it does not matter. How many tools are used in the program will default to the set two-dimensional coordinates of the workpiece.The length of each tool is different. After the tools are compensated in the length direction, the machining accuracy of the machine tool can be guaranteed as long as the program does not make mistakes. In theory, the CNC machine tool can process the machining accuracy given by the program.

"Old Wu, we used aluminum for this cutting test, so the cutting elements should not be set too small. Otherwise, it is impossible to measure the rigidity of the machine tool, and the machining accuracy cannot be detected..." Yun Fei touched him by himself Said Wu Zhongda, the programmer.

Although the CNC milling machines produced by the company are already on the market, the debuggers of these CNC machine tools in the company are still relatively unfamiliar with the programming of machining centers.Wu Zhongdazu

Starting to enter Huadu Xinkaixing is to do programming. Lin Yajun is a machining center operator brought out by Yunfei himself. Now he is responsible for the NC machining programming and workshop management of the entire Chengdu Xinkaixing.

These two people, in theory, apart from Yun Fei, the entire Rongcheng can find the person with the best skills in programming and operating the machining center.After all, the entire Rongcheng, except Rongcheng Measuring Tools,

The Seventh Aerospace Academy next to it has bought a few machining centers in the last one or two years, and there are not a few CNC machine tools in Chengdu.

Let’s not talk about the technical level of the aerospace and capacity CNC technicians trained by German or Japanese technicians. The relationship between a few companies is not very good, and they will certainly not lend to nine CNC technicians who are too busy with production tasks. First heavy industry conducts machine tool debugging.

You know, the commissioning of a test machine cannot be done in a day or two.
