Super Weapon Swap System

UNIX system is not suitable for personal computers. Look 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 personal computers, Microsoft's DOS has become the mainstream.

Specialized in technology.

They took it, made some changes and used it. Although it can support it, it is definitely not the best.

Qin Guan could only shake his head reluctantly. Fortunately, Longxin 1 is about to become a past tense. Wait until Hanxin 1 comes out, and then build the strongest computer in China!

At work, the ocean horse was very attentive. Finally, he drew the last line. Then, as long as the computer calculated it by itself, the ocean horse turned around.

At first, the ocean horse could only use the apple 2 computer, with a frequency of 1MHz, and the running speed was very slow. Now, when these computers came, the ocean horse immediately threw away the apple 2 and began to use this most advanced computer. Compared with the original, the birds and guns changed.

"Mr. Qin, are you here?" Dayang Ma also respects Qin Guan. Now, Dayang Ma knows more and more inside stories, and respects Qin Guan more and more.

This man is unfathomable.

"Mr. Qin, Mr. Qin, you finally came." just then, several people came in behind.

When he heard that Qin Guan had come back, Zhang Gong hurried out of a workshop and came here, because when Bala had orders, they could enter any workshop, including here.

After coming in, he saw Qin Guan. Zhang Gong was very excited.

"I'm from institute 114. Now, we have completed the investigation of your factory and are very interested in several kinds of equipment. If our subordinate electronic factory can have these equipment, we can carry out production better," Zhang said.

Hearing her words, the ocean horse on one side tilted his mouth: "of course you can see good things, but if you want to use them, there's no way for the time being."

After that, Dayang Ma looked at Qin Guan: "President Qin signed an agreement with Steyr company last year and promised to deliver several CNC machine tools to Steyr company. Now, the date of the agreement is coming. If we can't fulfill it at that time, there will be compensation."

If Dayang Ma doesn't say it, Qin Guan will forget that last year, because of the patent problem, 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 its own.

Qin Guan nodded: "yes, I almost forgot. Simply, let's sell the CNC machine tools here to Steyr company."

there? Hearing Qin Guan's words, everyone was stunned. These machine tools have now completed their running in in in the factory. It is time to sell them?

Qin Guan nodded: "Our CNC lathes can only process to 0.001 mm, and the accuracy is not enough. Now, a machine tool factory in China can process to 0.0001 mm. Now, we need to update our equipment to further improve the processing accuracy. These backward machine tools can be handed over to Steyr company. I think they will not refuse."

Although it is technically difficult to increase from 0.001 to 0.0001, after all, the finer it is, the harder it is.

At the beginning, Qin Guan was afraid that the precision was too high and conspicuous. Therefore, he could only find some ordinary machine tools. The c400 horizontal milling machine exchanged had three-axis linkage, and the display interface was an ordinary seven segment nixie tube. There was also a data interface. It looked high-end and high-grade. It was produced in 1990. According to the gap with foreign countries, it was equivalent to the level of foreign countries in the 1980s.

In normal use, this machine tool can easily reach about 0.005. If repeated positioning is carried out, 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, the ultra precision machining dimension and position accuracy can be 0.01 to 0.3 μ m. The shape and profile accuracy is 0.003 to 0.1 μ m. Surface roughness of steel parts RA ≤ 0.05 μ m. Copper parts RA ≤ 0.01 μ m. There is still a number in our current level to future generations, not Huaxiong's boastful style.)

Qin Guan can't be too advanced. Now it's good to get 0.0001. At the same time, another development is to improve from the original three-axis linkage to five-axis linkage!

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

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 engine crankshafts, etc. it is a machine tool with high scientific and technological content and high precision, which is specially used for processing complex curved surfaces. The machine tool system is very important for a country's aviation, aerospace, military, scientific research, precision instruments High precision medical equipment and other industries have a pivotal influence.

Three axis linkage is not enough. Only five axis linkage can process extremely special surfaces, which can make the clamping of workpieces easier. There is no need for special fixture during processing, which reduces the cost of fixture, avoids multiple clamping, and improves the machining accuracy of die.

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

Even in later generations, this kind of machine tool belongs to the Western embargo.

In order to develop this kind of machine tool, Chinese researchers are also working hard. For example, a private enterprise with only about 120 employees is shining in future generations. It is Tuopu company.

Although the number is small, their scientific research ability is quite strong, because half of this small private enterprise are R & D personnel, and their founders are several doctors from Pearl Jiaotong University.

These doctors have long studied five axis CNC machine tools. In order to industrialize these technologies, they decided to establish an enterprise.

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

Even so, they resolutely decided to start a business, because the strength of the country is inseparable from them!

However, the market is ruthless. Due to excessive R & D investment and market sales, the company nearly broke its capital chain in early 2012.

However, after learning of the dilemma faced by this high-end equipment manufacturing enterprise, the government extended a helping hand and gave support to key projects. Therefore, topu achieved financial revenue and expenditure balance in 2012, and the order amount reached 190 million yuan in 2013.

At the same time, after the company lived, it has developed the first five axis machining center with independent intellectual property rights in China, which is used to produce the core component of aircraft, rocket and automobile engine turbocharger, impeller.

At the same time, with the technical support of this five axis CNC machine tool, topu has developed other equipment, such as fully automatic drilling and riveting equipment. There is even a "big guy" with a length of 40 meters and a weight of 260 tons, which is used for butt circumferential seam friction stir welding of large cabin assembly. These equipment are all in foreign countries and belong to the scope of prohibition.

High technology, relying on foreign countries is not enough. The strength of a country must depend on itself!
