Super military empire

These CNC machine tools are not the same as those seen in Hongshan Machinery Factory that have not been fully assembled. The complete technical form is no longer a simple four-axis machining center by adding a worktable on the three-axis machining center.

These are real machining centers.

The workbench, which was originally only a square, has become a circle, and the center of the workbench can actually rotate by itself, and the main shaft is horizontal, unlike the vertical one.

Looking inside through the transparent safety protection door of the machining center, a rotating part with a diameter of more than 500 stops quietly on the worktable, at an angle of 90 degrees to the axis of rotation of the part, and proceeded vertically. Machining of some special-shaped structures on the arc of the part.

After processing a place, the worktable rotates while moving.

"The four-axis horizontal machining center processes the core components of the engine. Because the assembly accuracy of the engine is very high, especially the spatial position, once it deviates from the tolerance range, even if it is equipped, it will cause a lot of damage to the product. Influence. Your Soviet Union relies on a large number of equipment and fixtures to ensure accuracy. Our industrial base is not as good as the Soviet Union, and even the economic strength is too far behind. But with such a processing center, things become simpler. The cost will become lower, because less equipment is needed, and fewer skilled workers are needed..." Liu Yijiu pointed to the four-axis machining center that was rapidly and automatically processing the engine and introduced it to the Soviets.

The comparison between CNC machine tools and special-line production immediately shows the advantages and disadvantages.

Tarkaf and others looked at these processing centers that were running automatically, and their eyes began to shine.It's not that the Soviet Union can't get it, but the Soviet Union can't produce it by itself!

The Chinese have a poor industrial foundation and overall weak technological strength, but they can produce CNC machine tools on their own. Even if the cost is higher, they don’t have to worry about sanctions.

Even if Norway is exporting some advanced computer technology or electronic parts to them, it will not work all day long. The core things have to be imported. Once there is a problem, the source will be cut off immediately. If they can't produce it, even the parts will be used. Can't keep up.

In addition to the four processing centers, the deal with Toshiba is more about core parts, such as spindles, servo motors and so on.

These are the key core components.

If it is only mechanical precision processing, even if it can be solved by high-level technical workers with a file, the combination of microelectronics and machinery is not so easy.

When the Soviets saw these CNC machine tools, how could they not be moved?

"Liu, these machining centers, your annual output is very high?" Now I don't have the mind to look at those four-axis machining centers that process complex curved surfaces or process parts on their own initiative. Tarkaf asked Liu eagerly. Nineteen.

"No, I said, all of us are laboratory-produced products. We can only maintain a monthly output of about ten units. The main reason is that the control system is too complicated..." Liu Yijiu is telling the truth.

These CNC machine tools are actually far from reaching the kind of technology decades later, but there is no way.

A lot of equipment, even if it is not perfect, must be used.

First of all, we must be determined whether there are any problems, and then we must solve the problems of technology and accuracy.Just like the construction policy put forward by the country, the problem of food and clothing should be solved first, and then the problem of getting rich and running for a well-off society should be solved.

"Ohhhhhhhhh..." At the very edge of the workshop, there is a machine tool whose running speed and spindle speed are higher than other equipment. This is different from other machining centers. There is no tool magazine, no The manipulator for automatic tool changer, even the shell is not completely enclosed.

The main shaft is very small, and the beam supporting the main shaft is not very thick.

"High-speed CNC milling machines, or engraving machines, are more suitable. They are mainly used for high-speed machining of some complex curved surfaces with high precision requirements..." Liu Yijiu introduced these special equipment.

The spindle is constantly moving up and down like a fast uphill and downhill, and the workbench below is also moving back and forth, just like men and women do things, of course, the frequency is much higher than that of humans for reproduction. The original movement.

High-speed spindle, high-speed movement, but not much noise.

"High-speed milling machines mainly use high-speed, high-movement, and high-speed machining for high-speed machining, so as to obtain better cutting quality. If the cutting amount is too large, it is not suitable. We are mainly used here for semi-finishing..." Liu Yijiu introduces the role of high-speed milling.

However, he did not tell the Soviets that this kind of processing is not so easy to use for some complex parts, especially difficult-to-machine materials, such as high-temperature alloys, nickel alloys, titanium alloys, and stainless steel.Difficult-to-machine materials require too much high-speed machining of their tools.

High-speed milling machines are only suitable for processing aluminum alloys and ordinary steel parts with relatively high hardness materials.

At least, this is the case when the tool has not made breakthrough progress.

Hard-to-machine materials are called hard-to-machine materials, not because of anything else, but because these materials have good mechanical properties and poor cutting performance.Often these materials have higher hardness and better toughness.The tool is required to have better hardness. The high hardness of the tool is destined to decrease the toughness...

In mechanical materials, if a certain material can combine mechanical properties such as high hardness, toughness, and even high plasticity, it will definitely cause a change in a certain field.

These, Liu Yijiu would not tell the Soviets.

Perhaps, based on the industrial level of the Soviets and the skills of Soviet experts, they will develop some more powerful knives!

Even if the Soviet Union disintegrated later, Europe and the United States would not export top materials to China.

These materials are basically used in top military manufacturing.

After visiting the factory, the Soviets couldn't wait to start negotiations with Director Liu. They couldn't even wait for the time to return to the Rongcheng Hotel. They found a conference room here and couldn't wait to start negotiations with the Chinese.

"Technology, we need a full set of technology, as long as we give us production technology, everything else is easy to talk about!" The manufacturing technology of CNC machine tools has no effect on the situation of the entire industrial system. For the efficiency, low-cost military industry, the effect is immeasurable.

For many high-precision and complex parts, the yield rate produced by the master craftsman is too low.

"General, I said at the beginning, technology is impossible. Only the whole machine is exported. Moreover, the technical performance is not discounted." Liu Yijiu shook his head firmly.

Once the Soviets had the technology, they would be able to start mass production in one or two years.

At that time, there will be no possibility that the Republic will export CNC machine tools to the Soviet Union.

"Furthermore, the technology of the tb-12 steam turbine must be discussed first. You have a month. If you don’t give us this technology, then the Americans will definitely trace the electronics that Toshiba exports to you. Products, at that time, maybe some of the computer chips that Norway smuggled to you might also be tracked down..." Liu Yijiu's words suddenly made the otherwise unharmonious atmosphere even more tense.

"It's free, it's impossible! Replace with the manufacturing technology of CNC machine tools!" Karlov sneered indifferently.

Smuggling complete sets of equipment is far less suitable than smuggling technology.

Technical exchanges between the Soviet Union and the West are still very frequent.

To be able to obtain a large number of CNC machine tools in China, and it is even possible to obtain the manufacturing technology of CNC machine tools, this is completely an unexpected surprise for them. How can they miss an opportunity that can obtain great credit?

"Don't let you give it for free, it's impossible to exchange it with the manufacturing technology of CNC machine tools!" Liu Yijiu thought in his mind what bad results would be for the whole of China if CNC machine tool manufacturing technology was given.

It also caused Liu Yijiu's headache to exchange something from the Soviets for technology.

What can be exchanged is basically not available to the Soviets.

If you give them machine tool technology, not CNC system manufacturing technology?

Just thinking of this, Liu Yijiu himself felt impossible.The mechanical manufacturing technology of the Soviets is much better than that of China. What they want is the manufacturing technology of numerical control systems, or in other words, what the Soviets want is mainly the manufacturing technology of chips.

The core of the CNC system is the chip.

This is the core of the entire system.

Will the Soviet Union lack the manufacturing technology of key mechanical parts?

"Then what can you change?" Karlov smiled and asked easily.

As long as the talks can continue, it is easy to say that it is impossible to obtain technology from Western countries. China has it. It cannot be obtained from Liu Yijiu. Perhaps it can be obtained from another unit.

As long as the chip is obtained, based on the Soviet Union, it will definitely do better than China.

At that time, the Soviet Union could carry out a large-scale transformation of the entire industrial system.

Liu Yijiu was silent. He really didn't know what technology would be better for the power system of a large ship.

China must develop the navy. They have started the research of naval equipment. It is useless without a power system.

"The material formula and production process of the depleted uranium alloy! The improved American m1 tank should use this material..." Liu Yijiu took a deep breath, as if he had cut his flesh, and let out a long breath. , Said with a heartache, "I can also provide you with pulse Doppler radar..."

Liu Yijiu has laid his laurels.

The Soviets also did not do well in radar because the electronics industry was not good, so the American fighters may not have their performance as good, but the radar is definitely better than theirs!

And Liu Yijiu’s pulse Doppler radar is more attractive to the Soviets than the manufacturing technology of CNC system!
