Take Off My Aviation Era

When he said this, Zhuang Jianye was bold and bold, and Merlinz was shocked.

But astonished to the astonishment, Merlinz did not believe in Zhuang Jianye's nonsense, but carefully looked at each device one by one, only to find that what Zhuang Jianye said was true.

Others may not understand what ultrasonic vibration processing technology is, but Merlinz, who started as aerospace technology and involved in the purchase and resale of aerospace parts, has long heard of it.

Even in the early years when Fairchild Aviation Manufacturing Company was profitable, Merlinz, who had just squeezed into Fairchild's senior management, advocated the introduction of several similar equipment for processing some materials with high hardness and brittleness.

So it is no stranger to ultrasonic vibration processing technology.

The so-called ultrasonic vibration processing technology, as the name suggests, is to add vibration elements in the machining process. Because the working frequency range of vibration is generally 17.5~48 kHz, which basically belongs to the frequency range of ultrasonic, it is called "ultrasonic vibration processing".

As for the generation of ultrasonic vibration, the high-level signal generator with piezoelectric ceramics as the core promotes the corresponding contraction and expansion of the piezoelectric ceramics through the discharge effect of the piezoelectric ceramics, thereby obtaining high-frequency vibrations of 17.5 to 48 kHz. The amplitude is not large, only 2~3 microns, which is not enough to affect the tool or drill used for machining.

Therefore, it must be further amplified to 3~50 microns by the horn device, and then controlled by a series of software and hardware. At the point of maximum amplitude, it is attached to the diamond particles or other hard materials of the tool or drill bit, and then hits the tool together. Surface, so that the effect of collaborative processing is achieved.

In this way, the benefits are obvious. Due to the additional properties of ultrasonic vibration, the mechanical processing equipment changes from periodic vibration only to regular forced vibration under periodic excitation, which not only suppresses the vibration of the tool or drill bit. It reduces the force and high temperature generated by machining, and enhances the dynamic stability of the machining system, thereby improving the quality of machining and the life of the tool or drill.

Of course, to achieve the above advantages is not as simple as installing an ultrasonic vibration processing generator, but requires an unusual knowledge and understanding of mechanical processing equipment.

This is not a simple disassembly that can be installed, except for a few faults to be expertly repaired, but it needs to be familiar with every detail and data.

The reason for this is very simple, that is, the machining equipment using ultrasonic vibration processing technology still has a key step that cannot be avoided, that is, adjustment.

Just like the car chassis, it is really not produced. It can be opened directly by installing a metal shell. The adjustment of the chassis is also an important part. Too soft or too hard will not work. Only impartiality can bring out the best of the vehicle. Good performance.

The same is true for machining equipment that uses ultrasonic vibration processing technology. It is not difficult to install an ultrasonic vibration generator. The principle lies in it. As long as ordinary workers who have received basic machining training look at the manual, they can easily install a piece of equipment. The modification is complete.

The question is, can such equipment be used?

Of course not.

The reason is simple. Do the frequency and amplitude of ultrasonic vibration match the spindle speed? Can it be transferred to the tool or drill bit of the equipment at the point of maximum amplitude? Should the feed rate of the equipment be matched? If the equipment has gears, should the amplitude of the ultrasonic generator be reduced first or the spindle speed should be controlled first? If it is a numerical control device, how should the various effects of ultrasonic vibration be integrated into the numerical control program...

All kinds of problems are different, but they can not be completed by general workers who are familiar with mechanical disciplines. They need to be completed by senior institutions that are fully knowledgeable about different equipment, different processes, and different processes. In other words, they have very rich experience in using equipment. Professional organizations with related manufacturing technologies are qualified to play these things.

Because of this, in the world, it can be said that there are only a handful of ultrasonic vibration processing technologies, and it is nothing more than the former Soviet Union, Japan and Germany that are among the top three.

With the disintegration of the Soviet Union, Russia has been behind in CNC machine tools for a long time. The ultrasonic vibration processing technology that used to be proud of is beginning to decline like this country. Japan is a little better, but as the asset bubble bursts, the economy begins to stagnate. In this regard, we are now tired.

Only after the agreement, Germany still leads the way in ultrasonic vibration processing technology. This is also an important reason why German machining equipment is internationally renowned. In addition to its strong background in mechanical equipment production, Germany has comprehensive adjustments in ultrasonic vibration processing technology. Do the best, so that the stability, controllability, and machining accuracy of German machine tools that apply this technology are the best in the world.

Even the United States, which claims that technology has crushed the solar system, sighs. It’s not that the United States can’t play ultrasonic vibration processing technology, but that the adjustments made by the Americans are not as silky as the Germans, plus the United States. People prefer to use high-precision processing equipment to manufacture high-precision products.

So customers ask what is your product made of?

Answer: Laser primer, electron beam coating, and plasma isolation. How do you listen to it? By the way, you can sit on the floor and start the price to earn more labor costs.

If you answer, it is produced with machining equipment equipped with ultrasonic vibration processing technology, which forces the grid to drop several levels immediately. How to sit down and raise the price?

This is why Fairchild was preparing to introduce similar equipment, but finally gave up and turned around to build an electron beam equipment that was three times more expensive.

No way, others have it, you don't, and customers think that your production technology is backward, so they won't give you an order.

But in this way, the price of domestic aerospace parts and accessories in the United States is soaring. In the end, Lockheed, which wants to reduce costs, has to turn around and seek the best solution. UU reading www.uukanshu. com

And all kinds of processing equipment using ultrasonic vibration processing technology is one of the few ways to control the cost of aerospace products. After all, the cost of mechanical processing equipment is much lower than that of lasers and electron beams. The addition of ultrasonic vibration processing technology is at best only half of high-precision equipment such as lasers and electron beams.

But what it makes is no better than high-precision equipment such as lasers and electron beams, and even has advantages that other equipment does not have in the processing of carbon fiber composite materials and metal matrix composite materials.

Therefore, Zhuang Jianye said that he wanted to bring down the cost of satellites, not just empty words, but insights that can be achieved.

However, Merlinz is not concerned about this at the moment, but looking at the dazzling DL series of professional aerospace equipment in front of him, his breath is constantly rising, and a big fat face dissatisfied with freckles is like a cooked crab, flushing. One slice is not exciting, but stimulated by the many devices that apply ultrasonic vibration processing technology.

So much so that I can’t help but roar, and send out three repetitive soul questions: “Is this China? Has Ascendas’ expertise in special aerospace equipment already terrifying? Um... Am I dreaming, at home? Sleepwalking in the living room..."
