These CNC machine tools are different from those seen in Hongshan Machinery Factory that have not been fully assembled. The complete technical form is no longer to install a workbench on the three-axis machining center to form a simple four-axis machining center.

These are real machining centers.

The original square workbench turned into a circular shape, and the middle of the workbench can actually rotate by itself. The difference between the spindle and the vertical one is horizontal.

Looking inside through the transparent safety protection door of the machining center, a rotating body part with a diameter of more than 500 was quietly stopped on the workbench, at an angle of 90 degrees to the rotation axis of the part, and processing some special-shaped structures on the arc of the part is vertically carried out.

After processing a place, the workbench rotates while moving.

"The four-axis horizontal machining center is processed on it. 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 have a great impact on the product. You, the Soviet Union, relying on a large number of equipment and tooling fixtures to ensure accuracy. Our industrial foundation is not as good as the Soviet Union, and even the economic strength is far inferior. But with such a machining center, things become simple and the cost will become lower, because there are fewer equipment and fewer technical workers..." Liu Yijiu pointed to the four-axis machining center that was quickly and automatically machining the engine and introduced to the Soviets.

The comparison between CNC machine tools and dedicated line production shows the advantages and disadvantages here.

Takav and others looked at these machining centers that were operating automatically and their eyes began to shine. It was not that the Soviet Union could not do it, but that the Soviet Union could not produce it itself!

The Chinese have poor industrial foundation and their overall technological strength are not strong, but they can produce CNC machine tools themselves. Even if the cost is higher, they don’t have to worry about being sanctioned.

Even if Norway exports some advanced computer technology or electronic parts to them, it will not work all day long, and core things must be imported. Once a problem occurs, the source will be cut off immediately. If they cannot produce them themselves, even spare parts will not be able to keep up.

In addition to four machining centers, the transactions with Toshiba are more of core spare parts, such as spindles, servo motors and other things.

These are key core components.

If it is just precision machining in mechanical aspects, even if it is possible for advanced technical workers to solve the problem with files, it is not so easy to combine microelectronics and machinery.

How could the Soviets not be moved when they saw these CNC machine tools?

"Liu, your annual output of these machining centers is very high?" Now there is no time to look at the four-axis machining centers that process complex curved surfaces themselves or actively change positions to process parts by themselves. Takav asked Liu Yijiu very anxiously.

"No, I said, we are all products produced in laboratories, and we can only maintain the output of about ten units per month. 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 technology that will be decades later, but there is no way.

Many equipment, even if it is not perfect, must be used.

First of all, we must firmly resolve the problem of existence or not, and then solve the problem of technology and precision. Just like the construction policy proposed by the country, we must first solve the problem of food and clothing, and then solve the problem of getting rich and well-off.

"Wuwuwuwuwu..." At the edge of the entire workshop, there is a machine tool with higher operating speed and spindle speed than other equipment. This is different from other machining centers. There is no tool magazine, no robot that automatically changes the tool, and even the shell is not completely closed.

The spindle is very small, and the beam supporting the spindle 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 surfaces with relatively high accuracy requirements..." Liu Yijiu introduced these special equipment.

The main shaft is moving high and low like a rapid uphill downhill, and the workbench below is also moving back and forth, just like men and women doing that, of course, the frequency is much higher than the primitive movement of humans for reproduction.

The spindle at high speed moves without much noise.

"High-speed milling machines mainly use high-speed rotation, high movement, and snack tool volume for high-speed processing to obtain better cutting quality. If the cutting volume is too large, it is not suitable. We are mainly used for semi-finishing processing here..." Liu Yijiu introduced 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-process materials, such as high-temperature alloys, nickel alloys, titanium alloys, stainless steel, etc. The difficult-to-process materials have too high requirements for high-speed processing 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 true when the tool has not made any breakthroughs.

The reason why difficult-to-process materials are called difficult-to-process materials is not because of anything else, because these materials have good mechanical properties and poor cutting performance. Often, these materials have relatively high hardness and good toughness. It is destined that the toughness will decrease if the tool has better hardness and high hardness.

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

Liu Yijiu would not tell the Soviets about this.

Perhaps, with the industrial level of the Soviets and the abilities of Soviet experts, they will develop some more powerful knives!

Even if the Soviet Union collapsed later, the top materials, Europe and the United States, would not be exported to China.

These materials are basically used in top-level military manufacturing.

After visiting the factory, the Soviets couldn't wait to negotiate with Director Liu, and they couldn't wait to return to the Rongcheng Hotel, so they found a conference room here and couldn't wait to negotiate with the Chinese.

"We need a complete set of technology. As long as we produce technology, everything else is easy to talk about!" The role of CNC machine tool manufacturing technology in the situation of the entire industrial system is not to mention, but the role of this kind of machine tool in the entire military industry that requires high precision, high efficiency and low cost is immeasurable.

Many high-precision complex parts are produced by the masters, and the yield rate is too low.

"General, I said from the beginning that technology is impossible. There is only the whole machine export. Moreover, the technical performance is not discounted." Liu Yijiu shook his head firmly.

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

By then, there would be no possibility of anything happening when the Republic exported CNC machine tools to the Soviet Union.

"And, the technology of the tb-12 steam turbine must be given first before talking about it. If you don't give us this technology in a month, then the Americans will definitely track down the electronic products exported to you by Toshiba. At that time, perhaps Norway secretly smuggled some of your computer chips and other things may be found..." Liu Yijiu's words immediately made the originally unharmonious atmosphere even more tense.

"It's impossible to give it for free! Use the manufacturing technology of CNC machine tools!" Karov sneered indifferently.

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

Nowadays, the Soviet Union and the West have very frequent technical exchanges.

In China, you can obtain a large number of CNC machine tools, and even obtain the manufacturing technology of CNC machine tools. This is a completely unexpected surprise for them. How can you miss an opportunity to obtain huge contributions?

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

What to use to exchange technology from the Soviets was also a headache for Liu Yijiu.

What can be replaced basically cannot be given to the Soviets.

If they were given machine tool technology, they would not give them manufacturing technology for CNC systems?

When Liu Yijiu thought about this, he thought it was impossible. The Soviets' mechanical manufacturing technology was much better than China. What they wanted was the manufacturing technology of CNC systems, or in other words, what the Soviets wanted was mainly chip manufacturing technology.

The most core of CNC system is chips.

This is the core of the entire system.

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

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

As long as we can continue to talk, it is easy to say that there is no possibility of obtaining technology from Western countries. China has it, but it cannot be obtained from Liu Yijiu, and perhaps it can be obtained from other units.

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 have undergone large-scale dressing of the entire industrial system.

Liu Yijiu was silent. He really didn't know what technology to use to exchange for a large ship's power system.

China must develop its naval force. They have started researching naval equipment, and it is useless to have no power system.

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

Liu Yijiu has made up his old job.

The Soviets also did not work in radar because the electronics industry was not good. American fighter jets may not have the performance of theirs, but radar is definitely better than theirs!

The pulse Doppler radar that Liu Yijiu mentioned now is definitely more attractive to the Soviets than the manufacturing technology of CNC systems! (To be continued.)
