Chapter 382 Transfer of Equipment

    ¡°If someone else had said it, the head of the headquarters would not be like this, but when Peng Chuan and Wei Guangping nodded with certainty, the head of the headquarters knew that this was 80% correct.

    ¡°After all, the head of the headquarters is also a person who has been through the war years, and his judgment of people is still very accurate. Although the previous companions Peng Chuan and Wei Guangping were like wooden men, they were so nervous that they didn¡¯t know how to speak.

    However, the character of the two people was also touched by the head of the headquarters. Seeing that the two people definitely agreed, the head of the headquarters asked Zhuang Jianye with peace of mind.

    The chief asked this, so Zhuang Jianye naturally couldn't neglect it. He took the head of the headquarters and others to carefully look at the processing process of the entire set of equipment and several semi-finished products that had not yet been processed. He quickly told Peng Chuan: "Lao Peng, you  Go get the samples we made a few days ago."

    Peng Chuan was startled for a moment, then realized what he was doing. He responded and 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. We have not yet studied the more complex nickel-based alloys and titanium-based alloys, so we don't know.  The chief just mentioned what Factory 146 mainly produces. If the alloy structure of the parts is complicated, we may need to concentrate on research Haha, after all, our factory"

    Zhuang Jianye was hesitant as he spoke, and with appropriately flushed cheeks, he had just the right expression for a person who was weak but shy to show off his strength.

    Chemical milling is a common process for cutting complex thin parts such as the leading edge of aircraft wings and skins. After all, if the two to three millimeter thick blanks are processed purely mechanically, it is easy to cause damage to the parts due to poor precision control.

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

    However, this is not worthwhile in terms of cost. You must know that the complex thin parts of the skin on an aircraft need to be thousands at least. Among other things, similar parts of the Zeus-3 UAV sold by Tengfei Factory to Europe  There are more than 3,400 children.

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

    If each one needs to be processed with a multi-axis CNC machine tool, not only the tooling will need to be hundreds of plans, but the CNC programming will also need to be hundreds of times, and it will have to be replaced anytime and anywhere according to the production progress.

    This is equivalent to an invisible increase in labor costs several times.

    What's more, for mass production, the number of such high-precision machine tools must not be small. That's it. The problem is that the types must be large, medium, and small. Otherwise, you can use small five-axis machine tools that process palm-sized parts.  The axis machining center cannot handle the wasp-waisted curved surface skinning of the three- to four-meter-long fuselage even if it is stretched to its limit.

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

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

    On the other hand, chemical milling is much more cost-effective. As long as the actual conditions are adjusted well, the temperature is controlled well, 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 a process similar to machining.  , not only the batch size is large, but also repeatable, and the cost will naturally be greatly reduced.

    ¡°It¡¯s just that this seemingly uncomplicated process has two core points. One is the real-time measurement of the component when the chemical reagent is soaked; the other is the preparation of the etching liquid based on the characteristics of the material itself.

    The previous Tengfei factory was not a problem. Thanks to its accumulation in laser precision measurement, Tengfei factory has cooperated with the North China Institute of Optics to carry out research on other precision measurement aspects, and is already at the forefront of the country in this regard.

    What gives Tengfei Factory a headache is the accurate parameters and detailed metallographic characteristics of other alloy materials. There is no way, no matter how Tengfei Factory is doing, it is impossible to cover everything. The material is another technology tree, and it is also a huge pit. Tengfei Factory has already  Being unable to extricate itself from the aviation engine and special equipment, and adding composite materials, Tengfei Factory was exhausted both physically and mentally. It really did not have the ability to jump into the third pit, so it made some aluminum alloy etching fluids.  Just had to stop.

    But the problem is that we can¡¯t just stand still. After all, nickel-based alloys and titanium alloys will be widely used in future manned aircraft. If we don¡¯t figure it out, it will be very detrimental to Ascendas Factory¡¯s entry into the field of manned aircraft.

    So Zhuang Jianye gave an Oscar-winning performance, but he was hesitant to speak, and he was very shy. To put it bluntly, he wanted to use the head of the headquarters to get the national team to take action, and then Tengfei Factory would reap some benefits from behind.

    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 acceptable, I will coordinate with relevant departments to tackle the problem"

    As soon as he said these words, Zhuang Jianye's heart skipped a beat, and he finished his thoughts. He was a little bitch who was always playing tricks with others, so he was just asking for abuse. Now he's fine, and he has been looked at by the head of the headquarters, his heart, liver, spleen, stomach and kidneys.  Toru, you are still picking up a bargain. If you don't get picked up as a bargain, just burn the incense.

    So Zhuang Jianye¡¯s gleaming eyes quickly dimmed. Although he still agreed with a smile, his energy was much weaker than before.

    The head of the headquarters looked at the slumped Zhuang Jianye with a smile, and his smile became even brighter. He immediately turned to look at the parts next to him who were still confused by the extreme flip. The leader ordered: "This kind of basic research, I  I think your ministry should take the lead. If you can contact the aerospace department, the two of you can pool your strength together and select capable companies, units and universities to participate. This is called concentrating strength to do big things. This is our characteristic.  It is also an advantage of our system.¡±

    Then he pointed to the chemical milling equipment in front and continued: "A company that can build such equipment is very good, and it can make some appropriate policy inclines."

    The leaders of the ministries and commissions nodded quickly. This is considered an instruction. After returning home, it will be sorted out and turned into a formal document. As for Zhuang Jianye, he breathed a long sigh of relief. He finally joined the national team. A big stone fell to the ground.

    At this time, Peng Chuan also came over with two reinforced skin parts the size of a washbasin. The middle-aged officer surnamed Zhao quickly came up to him and held the parts in his hand. The skin on them was like a piece of paper sticker.  The four reinforced ribs are so thin that it makes people's hearts tremble, and they are afraid that they will break if they are not careful.

    The middle-aged officer surnamed Zhao also used the centralized measuring instrument to do it very carefully, then nodded with satisfaction, then turned to Zhuang Jianye and asked: "The quality of the components is very good, which means your equipment is very good. I don't know if you have  Not interested in transferring this equipment?"
