    ??In fact, this is indeed the case.

    The kdp crystal pioneered by the Americans was something that the Soviets during the Cold War dared not care about. They imitated it and used it in sensitive areas where it should be used. Not only did the Americans not dare to fart, they also had to hold their noses and praise it.  A well used sound.

    Which other country dares to be so arrogant?  The same goes for China. The Americans are open to the world in the research field, but they are very tight-lipped in the application field. Whoever crosses the red line will not kill you in the optical field, but will not make you ecstasy in other aspects.  die.

    This is all-round hegemony supported by super comprehensive national strength.

    Therefore, Tengfei Group can use kdp crystals to make solid-state lasers, but the treatment is not as good as Japan and South Korea. Not only does it have to pay twice the patent fee, but the kdp crystal solid-state lasers produced can only be used for cutting general steel and general aluminum alloys.  .

    Yes, you read that right. Paying the IQ tax will not allow you to use it properly. It will limit you to ordinary steel and ordinary aluminum alloys.

    Ascendas Group is an aviation and aerospace manufacturing company, not a workshop that processes aluminum alloy doors, windows and iron fences for courtyards. Such conditions in the United States are really a challenge to Ascendas Group¡¯s collective IQ.

    The price is high, there are conditions, and the most important thing is that it actually insults your IQ. Five years ago, Zhuang Jianye, who wanted to take shortcuts, was so shameless that he knelt down for related American technology companies. Finally, he couldn't kneel down anymore, because kneeling down didn't mean he didn't want it.  He was embarrassed, but including himself, the lives of tens of thousands of people in the Ascendas Group were going to be taken away by the Americans in a wave.

    So Zhuang Jianye slowly stood up with his arms, then wiped the dirt from his knees, turned to his partner and said: "We are not allowed to take the shortcut, so we should do it ourselves."

    As a result, this effort will lead the world.

    Yes, it is truly No. 1 in the world, otherwise Zhuang Jianye would not be able to say that his Ascendas Group is the leader in the global laser field. This is not bragging, but a fact.

    Among other things, the nb-6600dl ultra-precision laser hole-making machine that amazed Aziz and others not only uses LBO crystals, which are different from American KDP crystals, but also Tengfei Group¡¯s completely independent intellectual property rights as the main material of solid-state lasers.  The processing technology is also not subject to foreign constraints.

    Because Tengfei Group uses femtosecond laser processing technology instead of traditional pulse laser.

    This is why Ascendas Group can use nb-6600dl ultra-precision laser drilling to replace the original electrochemical hole making equipment, becoming the key equipment for Ascendas Group's new generation flame tube and turbine blade film cooling hole processing.

    The core key is that Tengfei Group has mastered femtosecond laser processing technology.

    Although they are both lasers, femtosecond lasers are different from pulse lasers in that they have the characteristics of short time and high energy density. Because of this, the energy that femtosecond lasers act on components is not the heat energy of pulse lasers, but a similar energy.  Coulomb repulsion of ionization.

    Because this femtosecond laser excites and removes free electrons in the material when it interacts with the material, and relies on the Coulomb repulsion between positively charged material molecules to remove the material, thereby eliminating the generation of heat under this mechanism.

    At the same time, because the peak power of the femtosecond laser can reach up to 10 megawatts, and the electric field intensity is extremely high, which is much larger than the Coulomb field within the atoms, it is enough to ionize any material and realize the plasma in the working area.  form is removed.

    Based on this, the femtosecond laser can perform micro-precision cold processing such as hole making, micron-level etching, and cutting on any material, and will not produce thermal stress, recast layer, micro-cracks, etc. on the processed parts, which is enough to withstand the turbine blade air pollution.  Processing of film cooling holes and flame tube precision cooling hole groups.

    From the thermal processing of pulse laser to the plasma removal of femtosecond laser, Tengfei Group has not only broken the monopoly on solid-state lasers, but also is at the forefront of the world in processing technology.

    We must know that the precision machining of film cooling holes in today's world is still dominated by electrochemical machining equipment.

    It cannot be said that this process is not excellent. The problem is that the efficiency of electrochemical processing is really not flattering. Not only that, for different materials and different compositions, the configuration of electrochemical liquids is also different.

    So often the cost of one milliliter of electrochemical liquid is almost as much as one gram of gold.

    That¡¯s all. Anyway, the value of the aircraft engine itself is much more expensive than the same weight of gold. The problem is that the failure rate of electrochemical processing is too high.

    There is no way. The chemical liquid guide tube on the electrochemical processing equipment is easily corroded by the internal chemical liquid, so it needs to be replaced frequently. In addition, the coordination agency of the equipment must also coordinate in real time, otherwise the chemical liquid injection will be too fast or too slow.  It will affect the processing accuracy of the material.

    A little negligence, the wholeThe equipment will be laid out for you to see.

    If other equipment is lying around and repaired, it doesn¡¯t matter. It¡¯s all machinery anyway. It¡¯s not a big deal if it¡¯s disassembled and reassembled. The problem is that the chemical liquid still remains in the electrochemical hole-making equipment. Not only is it expensive, but some types are also  poisonous.

    So this thing is laborious to produce, and it can drive people crazy when repairing it.

    I don¡¯t know what happened to other aircraft engine manufacturing companies. Anyway, Ascendas Group was almost crazy after being tortured by this thing in the past few years, but no matter how crazy it was, it had to endure it at the time, because in addition to electrochemical precision hole processing equipment, it can be used once at normal temperature.  There is no other equipment that can replace the film cooling holes of turbine blades.

    The key to Ascendas Group¡¯s second-generation core machine is the film cooling holes of the turbine blades, which is impossible not to do.

    So no matter how troublesome it is, no matter how high the failure rate is, Ascendas Group has to admit it by pinching its nose.

    But now, Tengfei Group has mastered the solid-state laser and conquered the femtosecond laser processing technology. In the past, the processing of film cooling holes, which used to be painful at the production end, suddenly became much simpler.

    There is no need to readjust the chemical liquid according to the materials, nor to adjust the hose and speed, nor to worry about the toxicity of the chemical liquid and possible malfunctions.

    It¡¯s also normal temperature, it¡¯s also cold processing, it¡¯s also one-time molding.

    nb-6600dl ultra-precision laser hole making machine is just like an ordinary CNC machine tool. Place the parts on the workbench, then enter the CNC program, and the laser will punch out micro-precision holes one by one with femtosecond laser.

    If we have to say that the nb-6600dl ultra-precision laser hole making machine is different from other precision hole processing equipment, it is that the environmental requirements for the workshop are extremely high, almost reaching the environmental requirements of semiconductor production.

    There is no way. The inside of the nb-6600dl ultra-precision laser hole making machine is full of precision optical components. The slightest contamination will affect the processing accuracy, so the investment in the construction of the workshop is very considerable.

    But even so, the efficiency and accuracy of the nb-6600dl ultra-precision laser hole making machine are there. Even including the huge investment in the workshop, the overall cost is still one-third less than that of electrochemical hole making equipment.

    Because of this, once Tengfei Group mass-produced the nb-6600dl ultra-precision laser hole-making machine, the engine manufacturer put all the nb-66 electrochemical hole-making equipment in hand and completed a leapfrog upgrade.

    However, many of those electrochemical hole-making equipment were in good condition. It was a pity to just leave them in the warehouse and collect dust. So after Zhuang Jianye and Aziz and others discussed the laser hole-making process, Zhuang Jianye changed the subject: "We  Ascendas Group is very sincere in its cooperation with the two countries. I am also a real person. I have always been a gentleman before a villain. The nb-6600dl ultra-precision laser hole making machine is an advanced equipment that is prohibited from export in our country. This time I can bring Ah  Mr. Ziz, your entry was specially approved by the head of our headquarters in order to show our sincerity in cooperation.

    But for me personally, just looking at something is not sincerity. Just as I said to His Highnesses Abdullah and Mahmoud in Pakistan, since cooperation must be mutually beneficial and win-win, if you invest money, we will  Of course, we have to come up with good technology and good craftsmanship. This is called sincerity, right?

    Therefore, the nb-6600dl ultra-precision laser hole making machine cannot be sold. I can always provide other advanced equipment and technology to my partners. I applied to the head of the headquarters and tried my best to persuade him for three days before he relented and agreed to our takeoff.  The group sold nb-66 electrochemical hole-making equipment to the two countries. The original unit price was US$200 million, but as a sign of good faith, the price was discounted by half, to US$100 million per unit!  "

    "Really?" When Aziz heard this, his old eyes immediately widened.
