Unix system is not suitable for personal computers. You will know by looking at later generations. Personal computers are either Microsoft or Apple. Many people don’t know Unix. Because this system is used on servers.

Even now, unix is ​​also used on minicomputers. Although they want to sell to personal computers, Microsoft's dos has become the mainstream.

Industry specializing in surgery.

They took it, made a slight modification, and used it. Although it can support it, it is definitely not the best.

Qin Guan could only shook his head helplessly. Fortunately, Loongson One is about to become a thing of the past. When Hanxin One comes out, let's build the strongest domestic computer!

At work, Dayangmar was quite attentive, and finally drew the last line. Then, as long as the computer did the calculations, it was enough. At this time, Dayangmar turned his head.

At the beginning, Dayangmar could only use Apple 2 computers with a frequency of 1Mhz, and the running speed was very slow. Now, when these computers came over, Dayangmar immediately threw away the Apple 2 and started using this most advanced computer. Compared with the original, the shotgun is changed.

"Mr Qin, are you here?" Dayangma also respects Qin Guan, and now Dayangma knows more and more inside stories, and he respects Qin Guan more and more.

This person is unfathomable.

"Ms. Qin, Mrs. Qin, you are finally here." At this moment, several people came in behind him.

When he heard that Qin Guan had returned, Gong Zhang hurried out of a workshop and came over here, because Heribala had instructed them to enter any workshop without hindrance, including here.

After entering, he saw Qin Guan, and Zhang Gong was very excited.

"I belong to 114. Now, we have completed the inspection of your factory. We are very interested in several kinds of equipment. If our subordinate electronics factory can have these equipment, we can do better production." Zhang Gong said.

Hearing what she said, the big Yangma on the side curled his lips: "Good stuff, of course you can see it, but if you want to use it, there is no way for the time being."

After talking, Dayang Mar looked at Qin Guan: "Mr Qin, he signed an agreement with Steyr last year and promised to deliver several CNC machine tools to Steyr. Now, the date of the agreement is about to arrive. At that time we can't fulfill it, but there will be compensation."

If Dayang Mar didn't say anything, Qin Guan would have forgotten it. Last year, because of patent issues, negotiations were finally formed, and everyone cooperated for a win-win situation.

One of them is to provide Steyr with advanced CNC machine tools, at least at the same level as our own.

Qin nodded his point of view: "Yes, I almost forgot, just let's sell the CNC machine tools here to Steyr."

here? Hearing Qin Guan's words, everyone was stunned. Now that these machine tools have been run-in at the factory, they were sold at the right time to put their efforts?

Qin nodded his opinion: "Our CNC lathes can only process up to 0.001 mm, and the accuracy is not enough. Now, a certain domestic machine tool factory can already process up to 0.0001 mm. Now, we need to update our equipment. To further improve the processing accuracy, these backward machine tools will be handed over to Steyr. I think they will not refuse."

Regardless of the increase from 0.001 to 0.0001, it is technically difficult. After all, the more refined, the more difficult it is.

At the beginning, Qin Guan was afraid that the accuracy was too high and too conspicuous, so he could only find some ordinary machine tools, exchanged C400 horizontal milling machine, three-axis linkage, the display interface is an ordinary seven-segment digital tube, and there is a data interface. , It seems that the high-end atmosphere is high-grade, and it belongs to the production in 1990. According to the gap with foreign countries, it is equivalent to the level of foreign countries in the 1980s.

This machine tool, in normal use, can reach about 0.005 casually. If repeated positioning is performed, it can be reduced to less than 0.002. With the grating, the accuracy will be further reduced to less than 0.001, but it will be difficult to improve it.

(In later generations, ultra-precision machining size and position accuracy can be 0.01 to 0.3μm, shape and contour accuracy is 0.003 to 0.1μm, surface roughness steel parts Ra≤0.05μm, copper parts Ra≤0.01μm, our current Level, there will be a figure in later generations, not Huaxiong's flamboyant style.)

Qin Guan can't be too far ahead, now it's 0.0001, it's pretty good. At the same time, another development is to increase from the original three-axis linkage to 5-axis linkage!

The more the number of axes, the more complex parts can be processed, and the five-axis linkage is even more powerful.

It can be said that the five-axis linkage CNC machine tool system is the only means to solve the processing of impellers, blades, marine propellers, heavy generator rotors, steam turbine rotors, large diesel crankshafts, and so on. It is a high-tech, high-precision machine tool specially used for processing complex curved surfaces. The machine tool system has a pivotal influence on a country’s aviation, aerospace, military, scientific research, precision equipment, high-precision medical equipment and other industries. .

Three-axis linkage is not enough, only five-axis linkage can process extremely special curved surfaces, which can make the clamping of the workpiece easier. No special fixtures are needed during processing, which reduces the cost of fixtures, avoids multiple clamping, and improves mold processing accuracy.

From ordinary machine tools to CNC machine tools, it is a step, and the step is even higher with three-axis linkage to five-axis linkage.

Even in later generations, this kind of machine tool is also subject to the Western embargo.

In order to develop this kind of machine tool, Han Guo's scientific research personnel are also working hard. For example, a private enterprise with only about 120 employees will be shining in later generations, and it is Topu.

Regardless of the small number of people, their scientific research capabilities are quite strong, because half of this small private enterprise is research and development personnel, and their founders are several PhDs from Mingzhu Jiaotong University.

These PhDs have been studying five-axis CNC machine tools for a long time. In order to industrialize these technologies, they decided to establish a company.

They are well aware that the enterprise founded by technical experts is "nine die for a lifetime". Because technology holders do not understand corporate management, capital operation and related laws, there is a lack of a mechanism to combine technology capital, management capital and financial capital in China.

Even so, they decided to start a business resolutely, because the power of the country cannot do without them!

However, the market is ruthless. Due to excessive R&D investment and market sales failed to keep up, the company almost broke the capital chain in early 2012.

However, after learning of the dilemma faced by this high-end equipment manufacturing company, the government extended a helping hand to support key projects. As a result, Tuopu achieved financial balance in 2012 and achieved an order amount of 190 million yuan in 2013.

At the same time, after this company survived, it has developed the first domestic five-axis machining center with independent intellectual property rights to produce the core components and impellers of turbochargers for airplanes, rockets and automobile engines.

At the same time, with the technical support of this five-axis linkage CNC machine tool, Topu has developed other equipment, such as fully automatic drilling and riveting equipment. There is even a 40-meter-long, 260-ton "big guy", which is used for **** joint ring seam friction stir welding for large cabin assembly. These devices are prohibited from sale abroad.

High-tech, it is impossible to rely on foreign countries, a country's strength must rely on itself!
