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

These are real machining centers.

The workbench, which was originally just a square, has become a circle, and the middle of the workbench can rotate by itself, and the spindle is different from the vertical type, which is a horizontal type.

Looking through the transparent safety door of the machining center, a rotary body part with a diameter of more than 500 is quietly parked on the workbench, and the rotary axis of the part is at an angle of 90 degrees, and some special-shaped structures on the arc of the part are processed vertically.

When the machining is done in one place, the table rotates while moving.

"Four-axis horizontal machining center, the processing is the core parts of the engine, due to the high assembly accuracy of the engine, 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, relied on a large number of equipment and fixtures to ensure accuracy. Our industrial base is inferior to that of the USSR, and even our economic strength is too far behind. But with such a machining center, things will be simpler, and 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 machining the engine and introduced it to the Soviets.

The comparison between CNC machine tools and special line production is presented here at once.

Takaf and the others looked at these machining centers that were running automatically, and their eyes began to glow. It's not that the Soviet Union couldn't get it. It's that the USSR itself could not produce it!

The industrial base of the Chinese is not good, and the overall scientific and technological strength is not strong, but they can produce their own CNC machine tools. Even if the cost is higher, there is no need to worry about being sanctioned.

Even if Norway exports some advanced computer technology or electronic components to them, they can't do it all day, and the core things have to be imported, and if there is a problem, the source will be cut off immediately, and they will not be able to produce it themselves. Even the spare parts can't keep up.

In addition to the four machining centers, the deal with Toshiba is more about core parts. Such as spindles, servo motors, etc.

These are key core components.

If it is only precision machining in machinery, even if it is a file that can be solved by high-level skilled workers, microelectronics and machinery can be combined. It's not that easy.

When the Soviets saw these CNC machines. How can you not be impressed?

"Liu, these processing centers, your annual output is very high?" Now I don't have the heart to look at those four-axis machining centers that process complex surfaces by themselves or take the initiative to change positions to process parts, Takaf asked Liu Yijiu very eagerly.

"No, I said, these are all products produced in the laboratory, and we can only maintain an output of about ten units per month, mainly because ......the control system is too complicated," Liu Yijiu said the truth.

These CNC machines are nowhere near the technology that they were decades later. But there is no way.

A lot of equipment, even if it's not perfect. It has to be used.

First of all, we must resolutely solve the problem of whether there is or not, and then solve the problem of technology and precision. Just like the construction policy put forward by the state, we must first solve the problem of food and clothing, and then solve the problem of becoming rich and becoming well-off.

"Woo woo woo woo ......" in the most edge of the whole workshop, there is a machine tool that is higher than other equipment in terms of running speed and spindle speed, which is different from other machining centers, there is no tool magazine, there is no automatic tool change manipulator, and even the shell is not fully enclosed.

The spindle is very small, and the beams supporting the spindle are not very thick.

"High-speed CNC milling machine, or engraving machine is more suitable, mainly used for high-speed processing of some high-precision requirements, complex surface ......," Liu Yijiu introduced these special equipment.

The spindle is moving up and down as quickly as it is going uphill and downhill, and the workbench below is also moving back and forth, just as men and women do that, with a much higher frequency than the primitive movement of human beings for the sake of reproduction.

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

"High-speed milling machine, mainly the use of high speed, high movement, snack knife amount for high-speed processing, so as to obtain better cutting quality, if the amount of cutting is too large, it is not suitable, we are mainly used here for semi-finishing ......" Liu Yijiu introduced the role of high-speed milling.

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

High-speed milling machine is only suitable for processing aluminum alloy and ordinary steel parts with relatively high hardness.

At least, that's when there was no breakthrough in tooling.

The reason why difficult-to-machine materials are called difficult-to-machine materials is not because of anything else, but because these materials have good mechanical properties and poor cutting performance. Often these materials are relatively high hardness and toughness. The tool is required to have better hardness, and the high hardness of the tool is destined to reduce the toughness......

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

Liu Yijiu will not tell the Soviets about this.

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

Even if the Soviet Union collapsed later, top-quality materials, Europe and the United States would not be exported 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, and they couldn't even wait for the time to return to the Rongcheng Hotel, so they found a conference room here and couldn't wait to start negotiations with the Chinese.

"Technology, we want 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 plays an important role in the situation of the entire industrial system, but this kind of machine tool is immeasurable for the entire military industry that needs high precision, high efficiency and low cost.

Many high-precision complex parts, relying on the master to produce the yield is too low.

"General, I said at the beginning, technology, there is no possibility. Only the whole machine is exported. Moreover, the technical performance is not compromised. Liu Yijiu shook his head firmly.

Once the Soviets had the technology, they would be able to start manufacturing on a large scale in absolutely a year or two.

At that time, there will simply be no possibility of the Republic exporting CNC machine tools to the USSR.

"Moreover, the technology of the TB-12 steam turbine had to be given first. You have a month, and if you don't give us the technology in this area, then the Americans will definitely track down the electronic products that Toshiba exported to you, and when the time comes, maybe some of the computer chips that Norway secretly smuggled into you may also be traced......" Liu Yijiu's words suddenly made the already not very harmonious atmosphere even more tense.

"Give it for free, impossible! I change it with the manufacturing technology of the CNC machine! Karloff sneered indifferently.

Smuggling equipment is far less suitable than smuggling technology.

At present, technological exchanges between the Soviet Union and the West are still very frequent.

Being able to obtain a large number of CNC machine tools in China, and even the possibility of obtaining CNC machine tool manufacturing technology, is a complete unexpected surprise for them, an opportunity to get a huge credit, how can they miss it?

"I don't want you to give it for free, it's impossible to exchange it with the manufacturing technology of CNC machine tools!" Liu Yijiu was weighing in his heart that if he gave CNC machine tool manufacturing technology, there would be bad results for the whole of China.

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

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

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

Just thinking of this, Liu Yijiu himself felt that it was impossible. The Soviets' mechanical manufacturing technology is much better than that of China, and what they want is the manufacturing technology of the numerical control system, 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 whole system.

The manufacturing technology of key mechanical parts, which the USSR would lack?

"And what do you have to exchange?" Karloff smiled and asked very easily.

As long as we can continue to talk about it, it is easy to say that it is impossible to obtain technology from Western countries, and China has it, but it cannot be obtained from Liu Yijiu, and it may be possible to get it from other units.

As long as you get the chips, on the basis of the Soviet Union, you will definitely do better than China.

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

Liu Yijiu was silent, he really didn't know what technology was better to use for the power system of a large ship.

China must develop its navy, and they have embarked on research on naval equipment, and it is useless without a power system.

"The material formulation and production process of depleted uranium alloy! The Americans' M1 tank modification should use this material......" Liu Yijiu took a deep breath, as if cutting his flesh, before he exhaled a long breath and said very heartbrokenly, "I can also provide you with pulse Doppler radar ...... again"

Liu Yijiu is already in the old book.

The Soviets are also not good at radar because the electronics industry is not good, and the performance of the American fighters is not necessarily as good as theirs, but the radar is definitely better than theirs!

And the pulse Doppler radar that Liu Yijiu is talking about now is definitely more attractive to the Soviets than the manufacturing technology of the numerical control system! (To be continued.) )
