Smart Industrial Empire

Yun Fei secretly hated that he didn't learn computer programming, otherwise he would set up a software company and pirate the classic operating systems of Microsoft, not to mention bankrupt Microsoft, at least, he, Yun, and not Bill would be the richest man in the world in the future. Old stuff.

"Xiaoyun, the tool magazine of the machining center in the laboratory will conduct the first experiment tomorrow. Do you have time to go to the site to have a look?" Yun Fei was wandering around, not noticing that it was almost time to get off work.

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

The military provides not only electronic personnel, but also knows that Yunfei lacks many experienced professional and technical personnel in mechanical and hydraulic pneumatics, so it actively provides Yunfei with dozens of personnel from some of their factories and research institutes. technical engineer.With the addition of these people, the team efficiency of Situ He Yun and Sun Lin increased instantly.Most of these joiners are over forty years old, which is not comparable to the young graduate students they bring.

Yun Fei is also clear about the purpose of the military.

Because the country puts the focus of development on the economic field, the military invests very little in military equipment. In addition to maintaining a standing army of millions and updating some really old weapons and equipment, the military expenditure has not been much. Investing research funds in some of the most expensive fields, such as the aerospace field, which is related to the entire national defense industry, there is no extra funds to invest in some ordinary conventional weapons and equipment.

Without the investment of research funds, the military's huge research team can only sit idle with their salaries.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 grassroots researchers in the military can maintain their research status in Jiuyi Heavy Industry, so that their research capabilities will not gradually deteriorate; and Jiuyi Heavy Industry.It solves the gap problem of the scientific research team that they have been lacking for a long time.

Of course, these researchers cannot serve Jiuyi Heavy Industry forever. As long as the military's stalled projects start again, these researchers who belong to the military will all evacuate Jiuyi Heavy Industry and return to their affiliated units.Fortunately, Yun Fei 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 evacuate, they must discuss with Jiuyi in advance. These are written in black and white in the secret contract.

In an environment where a large number of state-owned enterprises have gone bankrupt.These military technicians and engineers were well settled, and the cooperation with Jiuyi Heavy Industry explored a new cooperation model. This was also when the domestic economic situation improved and the country gradually began to vigorously develop armaments. , The reason why the military's high-precision weapons and equipment have blown out for a period of time.This is something to say, let's get down to business.

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 testing stage of various equipment of Jiuyi Heavy Industry.They are all in this test workshop.

"Old Sun, how's it going? Are you sure you can do it all at once?" The damn weather is getting hotter and hotter, and there is no central air conditioner.In the test workshop where there are only powerful fans whistling, even in the early morning when I just went to work, people don't feel much cool.

"Do you think this is an ordinary machine tool test? You can do it once, you boy. Anyone who knows knows that you are a little eager to see the machining center you produced appear on the market; those who don't know, think you The boy's confidence soared after he created a CNC milling machine in the company. He became arrogant..." Sun Lin gave Yun Fei a white look.

This kid, although he has not come to the mechanical test workshop for a while, even if he goes upstairs to the electronic research laboratory, he will not enter it. I don't know what the kid is up to. Sometimes he encounters some problems. If you want to talk to this kid, you can't find anyone.

"I have confidence in you guys!" Yun Fei smiled embarrassingly.

"This is not a CNC milling machine. We have been working on it for so many years. Although we have succeeded, the problems of positioning accuracy are not so easy to solve." Situ He Yun said to Yun Fei seriously.

"That's right, you don't even think about it, kid. Let's build a simple bamboo hat-style tool magazine first. You disagree, but you have to build a complicated disc-style tool magazine..." Regarding Yunfei's strategic approach, Sun Lin Very upset.

It is a challenge for him to start from the more difficult place at the beginning, which is exactly what he likes.It is also because the difficulty of the disc-type tool magazine is far greater than that of the hat-style tool magazine. After the tool magazine of the machine tool is rotated, when the tool is changed, the manipulator used to grab the knife may not be able to grasp the knife. Knife drop phenomenon.

Of course, the phenomenon of tool drop is a problem often encountered by CNC machining centers, and there are many factors for this.Generally, it is guaranteed to be within the range of a few ten-thousandths, that is to say, only one or two occasional tool changes will happen once or twice, otherwise, this kind of CNC machine tool will not be qualified at all.

The price of CNC tools is not comparable to that of ordinary tools, especially some customized CNC tools, a alloy milling cutter with a diameter of [-] mm may cost thousands of dollars, if the tool is damaged during the tool change process , 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 and machine tool are assembled, which involves many things. , Otherwise, it is impossible for China to fail to make much progress in CNC machine tools for decades. In the field of high-end machine tools, it relies on importing high-end machine tools from Germany, the United States, and Japan.

"This is not a problem. Anyway, what we are doing now is only a test machine. We still have time to gradually improve various problems." On the three-axis at the end, if you want to achieve self-sufficiency on high-end machine tools, it cannot be completed in a short period of time. It is very likely that they will not see it in their lifetime.

It would be a lie to say that Yunfei is not in a hurry.Several companies in Taiwan that are engaged in CNC machine tools are seeking to build factories in the mainland during this period.

Taiwan Youjia, Taiyu and other factories will build factories in the mainland at the latest in [-]. If the machining centers of Jiuyi Heavy Industry do not meet the technical parameters of the CNC machining centers they produce before then, for Jiuyi Heavy Industry, will be a disaster.

In China, whether it is official or private, there is a kind of blind worship for foreign technology.Everyone believes that the moon abroad is rounder than China. Otherwise, China has sent so many high-end talents to study at the expense of the state, but in the end they will automatically stay in the capitalist world to be exploited by those vampire-like capitalists.

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

The hydraulic workstation, pneumatic workstation, and tool magazine have been assembled on 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, performs positioning and positioning under some simple cutting actions. Accuracy issue.

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

The tool setting of the machining center is much more convenient than the tool setting of the 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 processing coordinate system of the part is not set separately How many knives are used in the program will default to the two-dimensional coordinates of the set workpiece.The length of each knife is different. After these tools are compensated in the length direction, as long as the program does not make mistakes, the machining accuracy of the machine tool can be guaranteed. In theory, the machining accuracy given by the program can be processed by the CNC machine tool.

"Old Wu, we used aluminum for this cutting test, and the cutting elements should not be set too small. Otherwise, the rigidity of the machine tool cannot be measured, and the machining accuracy cannot be detected..." Yun Fei said to himself Programmer Wu Zhongda said.

Although the CNC milling machines produced in the company have been sold on the market, the debuggers of these CNC machine tools in the company are still relatively unfamiliar with the programming of the machining center.Wu Zhongda the most

At the beginning of Xinkaixing in Huadu, programming was done. Lin Yajun is a machining center operator brought out by Yunfei himself. Now he is responsible for the programming of CNC machining programs and workshop management in Xinkaixing, Rongcheng.

Theoretically speaking, these two people, except for Yun Fei, are the best people in Chengdu who can find out the programming and operation skills of the machining center.After all, the entire Rongcheng, except Rongcheng Measuring Tools,

The Aerospace Seventh Institute next to it bought a few machining centers in the past one or two years, and there are not many CNC machine tools in the entire city of Chengdu.

Let’s not talk about the technical level of those CNC technicians who have been trained by German or Japanese technicians in aerospace and capacity. First heavy industry for machine tool debugging.

You know, the debugging of the test machine tool cannot be done in a day or two. (To be continued..)
