As far as the world's top machine tool technology is concerned, the use of linear motors and non-contact hydraulic bearings has gradually become the mainstream of the top CNC machine tools.

This is particularly critical to the use of linear motors, you must know that at present in China, the most mainstream machine tools, but also in the use of ball screw bearings, and AC servo motors.

And in this ball screw bearing, and AC servo motor, we also have to import from abroad, to meet their own needs, and the automotive industry, the same as the domestic large machine tool manufacturing enterprises, to be honest, is just to complete the final assembly of this step.

However, even if we use AC servo motors produced in Japan and ball screw bearings, our machine tools are still much worse than foreign products of the same level in terms of durability and high-speed acceleration.

Even a few years later, the Celestial Empire has developed into a big country in the world's machine tool industry, but when it comes to high-tech technology, it is still the same as before, with big but not precise problems, and the real core technology has not been mastered in place.

For example, this ball screw bearing, this thing is the equipment that controls the workpiece clamped on the machine tool fixture, up and down, left and right, back and forth, to cooperate with the processing tool to process the workpiece.

Or a device that controls the tool and processes the workpiece.

But because the balls we produce are not up to standard, so in the ball screw, our products have been inferior to foreign products, don't underestimate these small balls, it is these balls, in the ball screw, the movement of the ball screw, can control the operation of the mechanical arm freely.

Once these balls are not passed, then the trend of the ball screw will be a little deviation, which will lead to the entire workpiece being completely substandard, or even completely become a waste product.

The AC servo motor controls the operation of the whole machine tool, especially the speed, angle and strength of the tool used in processing, which are controlled by this AC servo motor.

If you don't control this motor well, it will also lead to the processing of the workpiece, which is not up to standard in terms of standards, and even has a certain difference and gap with the processing workpiece of other foreign countries.

However, when our country's machine tool processing industry is still having a headache for ball screw bearings and AC servo motors, foreigners have used non-contact hydraulic bearings and current motor motors to machine tools, and they have been in this field, ahead of us for more than a generation.

This is particularly important is the application of the current motor motor, if the non-contact hydraulic bearing, compared with the effect of the ball screw bearing, is only more flexible in the control mode, is not irreplaceable, then the linear motor motor, and the processing efficiency of the AC servo motor, it is completely different.

As early as the 1996 Chicago Machine Tool Fair in the last century, large companies in the United States, Germany and Japan have begun to show the machine tools equipped with the current motor motors in front of the world, and once this machine tool was born, it also immediately showed their strong charm in front of the world.

Anyone who has been involved in machining and machine tools knows that if you want to process a straight groove on a hard workpiece, then the traditional machine tool using AC servo motor generally uses a tool to spiral forward on the surface of the workpiece, and then carve a straight groove on the workpiece.

In this way, the machine tool itself, as well as the cutter, will cause great impact and wear, but also to ensure that the motor of the machine tool works in the case of high strength, in order to ensure the forward speed of the tool, but also to ensure that the speed of the tool can reach a considerable degree, so as to complete the accurate machining of the groove. …,

However, although the AC servo motor has been adjusted many times, when encountering such a processing problem, it will still make the personnel operating the machine tool rush to a headache, because this kind of work is the most difficult to do, and a bad one is not good because of the wear at the end, or the rotation speed is not enough, it will lead to the abandonment of the entire workpiece.

However, if the linear motor motor is used, there will be no such problem, because it can convert the electrical energy into very powerful mechanical energy of linear acceleration, that is to say, the machine tool using this kind of motor, when processing the above kind of workpiece, his tool does not need to spiral forward at all, only needs to be driven by the mechanical kinetic energy of strong linear acceleration, straight forward, and can complete a very straight groove processing on the hard surface of the workpiece.

And if the acceleration is sufficient, the accuracy deviation of the entire workpiece can even be less than 0.01%, which is completely different from the machining accuracy of ordinary servo AC motors.

And the most important thing is that with such a machine tool, the stroke will be completely unlimited, for example, if the traditional ordinary AC servo motor machining center is used, because of the limitation of the ball screw bearing manufacturing process, the general such a machining center, the maximum can only process, 4-6 meters of large workpieces.

However, if the machine tool with a linear motor is used, there is no need to worry about this at all, because the linear motor is used to drive the stator, the stator can be extended indefinitely, which means that his X-axis is not limited, so such a machining center can process a workpiece with a length of more than 40 meters, which is easy and not difficult at all.

And the positioning accuracy of this machine tool is very high, because it adopts the closed-loop positioning measure of the grating, the accuracy of this machining center can generally be controlled between 0.1-0.01 mm, and the error tracking is reduced by more than 200 times, and the nano-level control can be fully realized.

All in all, this kind of airport is definitely the latest generation of extremely high-precision products, which is very suitable for processing parts of cars, trucks, airplanes, ships and other large machinery.

If it is used in the military, then this kind of machine tool for the improvement of the military level, it is like a tiger wings, processing military aircraft or warships and submarines of the workpiece, it is a piece of cake, and even the processing of missile parts is absolutely not a problem.

But it is precisely because of this kind of machine tool that the Western world countries led by the United States, regarding such machine tools, are also very strictly controlled over the export of our Celestial Empire.

Out of some castration version, or a simplified version that will not have much effect on the production process of our country, they allow exports like the Celestial Empire, but as long as the machining technology of the Celestial Empire can be improved, they are not allowed to export to the Celestial Empire.

And in these countries, that is, Germany once exported a few very serious versions of the castration to the Celestial Empire, the United States and Japan, are not allowed to export to the Celestial Empire at all.

And the machine tools imported by Germany to the Celestial Empire, because the castration is very serious, so there is not much prominence in performance, plus the Germans are used to the lion's big mouth, the asking price of those machine tools is not expensive, and some domestic departments have given up the idea of introducing this machine tool from abroad.

Later, some universities or scientific research institutions were also organized in China to develop this kind of machine tool, but every year a lot of silver was smashed down, but the result was cheaper than the national liquor Moutai, as well as luxury hotels around the country, as for the scientific research results, but can only come up with more than one or two generations of products that are worse than others......

Jin Xiaoqiang had also entrusted Naruto Shinyuki to smuggle some large machining centers and smelting equipment from Japan before, but he did not get such machine tools. …,

Because he knew that in a country like Japan, which was very cautious about the Celestial Empire, it would definitely be even more difficult to get such equipment.

Although Naruto Shinyuki also got some machine tools that are currently the world's mainstream technology, they were also made when the security department opened one eye and closed one eye.

If he really wants to engage in such a sensitive equipment, I'm afraid that Naruto will not be able to sit in the position of the current president of the Ono Import and Export Trading Company in a beautiful way, and I am afraid that Guantanamo is the most suitable destination for him.

The reason why Japan's security agency turned a blind eye to Nato's cautious behavior of entrapment and private hiding was also related to the domestic economic recession for many years.

They are the world's largest exporter of machinery, and according to their estimates, the Celestial Empire's machining capacity is at least thirty years behind theirs.

Moreover, the demand for high-end CNC machine tools in the Celestial Empire is also very large, but because the Americans strictly abide by the Batumi agreement, they can only look at this cake but can't eat it, which also makes them feel a headache.

As long as the Celestial Empire can slowly improve the level of their machine tools, then the Americans will eventually have to relax the supervision of the Batumi agreement.

At that time, as long as the Americans open their mouths, they will take their best products and swarm into the Celestial Empire market, and crush all the local machine tool enterprises in the Celestial Empire, so that the market will still be theirs......

It's a pity that the Japanese don't know that Jin Xiaoqiang has begun to secretly start the independent research and development of machine tools, and has made such great progress, otherwise I am afraid that they will not be killed, so let these technologies flow into the Celestial Empire.

And this time, I don't know if it's a toss. Excel's luck is good, or should it be said that Jin Xiaoqiang's luck is good, the two people who have their own needs actually bumped into each other all of a sudden......

"Mr. Xcel, how much are those machines of yours worth? And how much do you owe to the bank, and how much money does Derek have in total? ”

Jin Xiaoqiang asked Fan with a smile. Xcel arrived, he was fascinated by this guy's machines......
