If someone else said it, the head of the headquarters would not be like this, but Peng Chuan and Wei Guangping nodded very affirmatively, and the head of the headquarters knew that this was eighty percent right.

How to say that the head of the headquarters is also a person who came from the war years, and his vision of people is still very accurate, although Peng Chuan and Wei Guangping, who accompanied him before, were like wooden people, and they were nervous and didn't know how to speak.

But the temperament of the two was also touched by the head of the headquarters, and seeing that these two people agreed with each other, the head of the headquarters asked Zhuang Jianye with a relaxed heart.

The chief asked so, Zhuang Jianye naturally couldn't be lazy, and took the head of the headquarters and other figures to carefully look at the processing process of the whole set of equipment, and a few semi-finished products that had not yet completed processing, and hurriedly ordered Peng Chuan: "Old Peng, you go and bring the samples we made a few days ago." ”

Peng Chuan was stunned for a moment, then reacted, and hurriedly trotted all the way to the finished product warehouse to get something.

Zhuang Jianye pointed to the chemical milling equipment in front of him and said: "At present, we have only studied the chemical milling process of several aluminum alloys, and we have not yet studied the more complex nickel-based alloys and titanium-based alloys, so I don't know what the 146 factory just mentioned by the chief is mainly producing...... Hehe, after all, our factory ......"

Zhuang Jianye said and spoke, and then stopped talking, with an appropriate flush of cheeks, and grasped the expression of a person who was not strong but was ashamed to show just right.

Chemical milling is a common process for cutting complex thin parts such as the leading edge of aircraft wings and skin, after all, if the blank with a thickness of two or three millimeters is processed by pure machining, it is easy to cause damage to the components due to poor precision control.

Even with the popularization of CNC machine tools, the accuracy has been greatly improved, and even multi-axis CNC can achieve the accuracy that was previously unattainable, which is enough to complete the processing of light and thin parts with complex curved surfaces.

However, this is not worth the cost, you must know that there are thousands of complex and thin parts of the skin on an airplane, not to mention that there are more than 3,400 similar parts of the Zeus-3 UAV sold to Europe by the Tengfei factory.

Divided into more than a dozen categories, hundreds of varieties.

If each one has to be processed with multi-axis CNC machine tools, the tooling alone will have to do hundreds of solutions, not to mention the CNC programming, and it will also have to be replaced anytime and anywhere according to the production schedule.

This is equivalent to an invisibly multiplier labor cost.

What's more, if you want to mass production, the number of such high-precision machine tools must not be less, if so, the problem is that the type must also be large, medium and small, otherwise you use a small five-axis machining center to process large parts, and you can't get the three, four-meter-long fuselage bee waist curved skin.

Similarly, a body machine that can process a body with a diameter of seven or eight meters cannot finish parts the size of a fingernail.

And there are not one or two parts like this, but thousands, tens of thousands, if they are all processed with this kind of high-end machining, no one can play with it.

On the other hand, chemical milling is much more cost-effective, as long as the actual deployment is good, the temperature is controlled, the parts to be processed are reserved, and then soaked in the chemical pool, and the erosion effect of the chemical reaction is used to complete the machining similar processing process, which is not only large in batch, but also repeatable, and the cost will be greatly reduced.

However, this seemingly uncomplicated process has two core points, one is the real-time measurement of the part when the chemical agent is immersed, and the other is the preparation of the erosion fluid based on the characteristics of the material itself.

The previous Tengfei plant is not a problem, thanks to the accumulation of laser accurate measurement, Tengfei factory has cooperated with the North China Institute of Optics to carry out other research on accurate measurement, which has been in the forefront of China.

What makes Tengfei factory a headache is the accurate parameters and detailed metallographic characteristics of other alloy materials, no way, Tengfei factory in how, it is impossible to do everything, the material is another science and technology tree, but also a huge pit, Tengfei factory has been in the aviation and special equipment two pieces can not extricate themselves, plus a composite material, Tengfei factory has long been physically and mentally exhausted, really unable to jump into the third pit, so a few aluminum alloy erosion fluid had to stop.

But the problem is that it is not possible to move forward like this, after all, nickel-based alloys and titanium alloys are very widely used in manned aircraft in the future, and if you don't figure it out, it will be very unfavorable for Tengfei Factory to enter the field of manned aircraft.

So Zhuang Jianye came up with an Oscar-level performance, and he wanted to stop talking, and he was shy, to put it bluntly, he wanted to use the head of the headquarters to let the national team go out, and then take off the factory to get some benefits in the back.

As a result, the head of the headquarters didn't even look at Zhuang Jianye, and waved his hand: "You don't have to worry about this, as long as your product performance is okay, I will coordinate with relevant departments here to tackle key problems......"

As soon as these words came out, Zhuang Jianye chuckled in his heart, and his heart was finished, he was such a little fresh meat and played with people in the old drama, so he didn't know what to do with abuse, now it's okay, he was seen through by the head of the headquarters, his heart, liver, spleen, stomach and kidneys, and he picked up cheap, and he didn't take it as cheap to pick it up.

So Zhuang Jianye's glowing eyes quickly dimmed, although he still smiled and agreed, but his spirit was much weaker than just now.

The head of the headquarters looked at Zhuang Jianye with a smile, smiled more and more brightly, and then turned his head to look at the part next to him that was still a little confused by the flip and ordered: "This kind of basic research, I think it is still led by your ministries and commissions, if you can contact the aerospace department, the two of you can concentrate together, and select capable enterprises, units and universities to participate together, this is called concentrating on doing big things, this is our characteristics, but also our institutional advantages." ”

Then he pointed to the chemical milling equipment in front and continued: "The company that can make such equipment is very good, and it can do some policy tilt appropriately." ”

The leaders of the ministry and commission nodded hurriedly, this is considered an instruction, and after going back, it will be an official document after a little tidying up, as for Zhuang Jianye, he breathed a long sigh of relief, he finally got on the national team, and a big stone fell to the ground.

At this time, Peng Chuan also came over with two basin-sized stiffener skin parts, and the middle-aged officer surnamed Zhao hurriedly greeted him and held the parts in his hand, and the skin on it was as if a piece of paper was pasted on the four stiffeners.

The middle-aged officer surnamed Zhao also carefully used the centralized measuring instrument to do it, and then nodded with satisfaction, then turned his head to look at Zhuang Jianye and asked: "The quality of the parts is very good, which means that your equipment is very good, I wonder if you are interested in transferring this set of equipment?"
