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

"Xiaoyun, the machining center tool magazine 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 in the world, not noticing that it was almost time to get off work.

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

The military not only provided electronic personnel, but also lacked many experienced professional technical personnel in mechanical, hydraulic and pneumatic aspects, and took the initiative to provide Yunfei with dozens of technical engineers in some of their factories and research institutes. With the addition of these people, the team efficiency of Situ Heyun and Sun Lin instantly improved. Most of these people are over forty years old, which is not comparable to the young graduate students they are carrying.

As for the purpose of the military, Yun Fei is also clear.

In addition to raising a standing army of more than one million and updating some weapons and equipment that are really old, the military also has to invest research funds in some cutting-edge fields that have a bearing on the entire national defense undertaking, such as the aerospace field, which burns the most money, and there is absolutely no extra funds to invest in some ordinary conventional weapons and equipment.

Without the investment of research funds, the military's huge research team would have to be idle on salaries. This is not only a serious waste, but also a sad thing for technical engineers who do not have a research project.

The entry of military researchers into the research department of Jiuyi Heavy Industry is a win-win cooperation for both sides. Those grassroots researchers in the military can maintain their research status in Jiuyi Heavy Industry and will not gradually degenerate in their research capabilities; And 91 Heavy Industry. It solves the problem of the shortage of scientific research teams that they have been lacking.

Of course, these researchers cannot serve Jiuyi Heavy Industry forever, as long as the military's stalled projects are started again, these researchers belonging to the military will all be evacuated from Jiuyi Heavy Industry and return to their home 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 communicate with Jiuyi Heavy Industry and Commerce in advance, which are written in white and black in the secret contract.

In an environment of a large number of bankruptcies of state-owned enterprises. These technical personnel and engineers of the military have been well resettled, and the cooperation with Jiuyi Heavy Industry has explored a new mode of cooperation, which is also the reason why the military's high-precision and sophisticated weapons and equipment have exploded for a period of time when the domestic economic situation has improved and the country has gradually begun to vigorously develop armaments. This is an afterword, and let's get down to business.

As soon as he got 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. It's all in this test workshop.

"Old Sun, how is it? Are you sure you can get it all at once? "It's damn weather, it's getting hotter and hotter, there's no central air conditioning. Only in the test workshop with a powerful fan whistling, even in the early morning of this just gone to work, people don't feel much cool.

"Do you think this is an ordinary machine tool test? One more time, you kid. Anyone who knows the Tao understands that you are a little eager to see your own processing center appear on the market; I don't know what to do, I thought that your kid's confidence skyrocketed after making a CNC milling machine in the company. Arrogant......" Sun Lin glanced at Yun Fei.

This kid, although he has not come to the mechanical test workshop during this time, even if he goes upstairs to the electronic research laboratory, he will not enter here, and I don't know what the idea of this kid is, sometimes I can't find anyone when I want to discuss with this kid when I encounter some problems.

"I have faith in you!" Yun Fei laughed wryly.

"This is not a CNC milling machine. We have been doing it for so many years, although we have succeeded, but this problem of positioning accuracy is not so easy to solve. Situ Heyun said seriously to Yun Fei on the side.

"That's it, you kid don't want to think about it, let's talk about making a simple bucket hat knife magazine first, you don't agree, you have to build a complex disc knife magazine as soon as you come up......" Sun Lin was very unhappy with Yun Fei's high-level approach.

Starting from the more difficult parts is a challenge for him, and that's what he likes. It is precisely because the difficulty of the disc tool magazine is far greater than that of the bucket hat tool magazine, after the machine tool magazine rotates, and then the tool is changed, the manipulator used to grasp the knife is likely to not be able to grasp the knife and the knife will fall off.

Of course, the phenomenon of tool drop is a problem often encountered in 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, 10,000 times of tool change, there will be one or two occasional occurrences, otherwise, this CNC machine tool is not qualified at all.

The price of CNC tools is not comparable to ordinary tools, especially some specially customized CNC tools, a ten-millimeter diameter alloy milling cutter, there may be thousands of pieces, if it is damaged because of the loss of the tool in the process of changing the tool, such a machine tool, who dares to buy?

These days, the test workshop has been working day and night on this thing, if the hydraulic and pneumatic aspects are controlled separately, there is no problem, now the entire tool magazine and machine tool assembly, this involves a lot of things, otherwise, China can not make much progress in CNC machine tools for decades, in the field of high-end machine tools, are relying on the import of high-end machine tools from Germany, the United States, Japan and these countries.

"This is not a problem, anyway, what we are doing now is just trying to test the machine, and we still have time to gradually improve various problems." Two old goods than Yun Fei more eager, foreign CNC machine tools, the development of each passing day, China is still trapped in the lowest-end three-axis, in order to achieve self-sufficiency in high-end machine tools, not in a short period of time can be completed, it is very likely, they will not see it in this life.

If Yun Fei is not eager, it is false. Several companies in Taiwan that make CNC machine tools are seeking to build factories in the mainland during this time.

Taiwan's Youjia, Taiyu and other factories will build factories in the mainland in 95 years at the latest, if before that, the machining center of Jiuyi Heavy Industry does not meet the technical parameters of the CNC machining center they produce, it will be a disaster for Jiuyi Heavy Industry.

In China, both official and non-governmental, there is a blind worship of foreign techniques. Everyone thinks that the moon abroad is rounder than China, otherwise, China will send so many high-end talents and spend the money provided by the state to study, but in the end it will automatically stay in the capitalist world and be exploited by those vampire-like capitalists.

"Get the program ready, all the knives are loaded, hurry up!" The machine bed is the use of Jiuyi Heavy Industry specially produced X-stroke 800mm, Y-axis stroke 500mm, Z-axis stroke 500mm machining center, this type of machining center, in China's CNC machining market, the most widely used.

Hydraulic workstation, pneumatic workstation, tool magazine in the first day has completed the assembly, today's first experiment is the assembly of the machining center after the assembly in the CNC tool change code program called the tool, positioning and some simple cutting action in the case of positioning accuracy.

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

After the machining center tool setting is completed, as long as the machining coordinate system of the part is not set separately, no matter how many tools are used in the program, the two-dimensional coordinates of the workpiece will be set by default. The length of each tool is different, after compensating these tools in the length direction, as long as the program is not wrong, the machining accuracy of the machine tool can be guaranteed, theoretically speaking, the machining accuracy given by the program, the CNC machine tool can be processed.

"Lao Wu, we are using aluminum in this cutting test, and the cutting elements should not be set too small. Otherwise, there is no way to measure the rigidity of the machine tool, and there is no way to detect the machining accuracy...... "Yun Fei said to Wu Zhongda, who was programming by himself.

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

Lin Yajun is the machining center operator brought out by Yun Fei himself, and is now responsible for the CNC machining programming and workshop management of the entire Rongcheng Xinkaixing.

These two people, theoretically speaking, are the people who can find out the best in the programming and operation skills of the machining center in the entire Rongcheng in addition to Yun Fei. After all, the entire Rongcheng, in addition to the Rongcheng measuring tools,

The Seventh Academy of Aerospace next to it has bought a small number of machining centers in the past one or two years, and there are not a few CNC machine tools in the entire Rongcheng.

Not to mention the technical level of the CNC technicians who have been trained by German or Japanese technicians in aerospace and capacity, the relationship between several companies is not very good, and the CNC technicians who are not busy with production tasks will definitely not be lent to Jiuyi Heavy Industry for machine tool debugging.

It is important to know that the debugging of the test machine tool is not something that can be done in one or two days. (To be continued......)
