Take Off My Aviation Era

Chapter 1239: Zero.15mm diameter film cooling hole

After hearing Zhuang Jianye's words, there was only one person in charge of the aviation development plant present, and their expressions were not pretty. There is no way that they have more or less Japanese processing equipment in their factories.

It’s not that these factories don’t want to use European and American equipment. The problem is that European and American equipment is not only expensive, but also has a particularly poor after-sales service. It often takes at least two months for the equipment to be broken and maintenance personnel from European and American manufacturers. All costs of the manufacturer's maintenance personnel shall be paid by the customer.

Eat well, live well, and play well, so that many aviation companies feel that they have not hired a foreign master who can help solve the problem, but have found a foreign grandfather to find their sins.

In contrast, Japanese equipment is not only relatively cheap, but also much more humane than European and American manufacturers in terms of after-sales. In addition, the details of Japanese equipment are well done, and the processing accuracy can also meet most of the needs of domestic aviation production. Therefore, domestic Major aviation factories have successively adopted Japanese processing equipment since the 1990s.

Of course, there are also individual factories that choose Japanese products not only because of equipment costs and after-sales issues, but for other purposes, such as the person in charge of the aviation manufacturing plant at Jiangangzhuang Jianye just now.

All the equipment of the aviation factory under his leadership is all Japanese products. That's all. As long as he has the opportunity, he will praise the high precision of Japanese equipment and the craftsmanship of the manufacturer at the small meeting, and try to introduce other brother factories to purchase Japanese products. product.

Obviously, it is because of the trust in Japanese products and the quality of Japanese equipment.

In fact, his eldest son studied in Japan after graduating from university. Not only did he receive joint funding from several large Japanese equipment manufacturing companies, he also established his own trading company and became the sole agent of those Japanese equipment manufacturers in China. .

So it’s not difficult to understand the actions of the person in charge of the Hangfa Manufacturing Factory. What helped the factory to upgrade its technology, and what worshipped the Japanese craftsman spirit? Obviously, I was helping my son make money secretly.

Talking about doctrine properly, and in my heart, tm is business!

Because of this, others have heard what Zhuang Jianye said. They are just a little worried about what to do if the Japanese equipment fails. After all, the opportunity to produce world-class guide blades is rare, and this opportunity should not be missed.

However, the person in charge of the Hangfa Manufacturing Factory was furious. You can smash the pot of our factory. You are still planning to smash your own pot. You Zhuang Jianye is a bit deceived, so the hanger who has been silent for a while The person in charge of the manufacturing plant couldn’t help it anymore, and opened his mouth directly: “Comrade Zhuang Jianye’s opinion is that I cannot agree. The quality of Japanese equipment is world-renowned, and their machining achievements are comparable to those of Germany. Japanese companies have a good artisan spiritual culture. Every piece of equipment they produce can no longer be regarded as an industrial product, but should be called a work of art.

So Comrade Zhuang Jianye just said that the accuracy of Japanese equipment is not enough, and it is a smashing thing. I think Comrade Zhuang Jianye’s one-sided personal understanding is that our factory uses Japanese equipment, which has always been very good, why there is no poor accuracy. Case?

Therefore, I have to doubt whether Ascendas Group has made any mistakes in the use of certain Japanese equipment. If so, I suggest that the cadres and employees of Ascendas Group go to our factory to exchange and learn. Others dare not say that they are in the use of Japanese equipment. Our factory still has some experience..."

After speaking for a while, he took a bottle of mineral water from the secretary beside him and took a sip to moisturize his throat, and then slowly continued: "What's more, all brother factories have introduced more or less. Japanese equipment is purchased at the expense of the country’s precious foreign exchange. How can it be discarded because the accuracy of Japanese equipment is not good? This is not a waste, but a serious loss of state-owned assets. Who bears the responsibility? Not to mention, Japanese equipment Is it really low precision? As I said before, there should be some misunderstandings about Japanese equipment, so I suggest..."

The person in charge of the Hangfa Manufacturing Factory deserves to be the central management cadre who has climbed all the way to this position. His eloquence is so good, and Barabara talked a lot later, which can be described as eloquent, well-organized, and extremely logical.

People in charge of other aviation development plants nodded their heads. It was not how good the director of the aviation development factory said, but the sentence "This is not a waste, but a serious loss of state-owned assets. Who bears this responsibility?" The big hat was buckled, and the people in charge of the other aviation development factories were a little bit too much to stand up to one of them.

Since I can't stand it, I can only agree with it. What else can I do? Could it be that you jumped up and said that the Japanese equipment that you spent hundreds of millions of yuan to purchase was thrown into the garbage?

Dare to say that today, and tomorrow I will wait for the end of get out of class to go home for the elderly!

Zhuang Jianye did not expect that the second time he raised the equipment problem, he would be thrown back by the middle-aged Mediterranean oily man in front of him who was always stinking. However, the whole person was neither angry nor surprised, but was very peaceful in his hands. The metal core and wave spring were completely extracted and passed to the person in charge of the aviation manufacturing factory who was still talking about the benefits of the Japanese equipment: "Leader, look at the average thickness of less than 5mm, and the material is hard. What kind of Japanese equipment can the 1845 0.15mm diameter film cooling holes on the brittle second-generation nickel-based alloy metal core be processed?"

The person in charge of the Hangfa Manufacturing Plant who was talking eloquently heard Zhuang Jianye's words and was stunned for a moment. Obviously, being interrupted made this a bit uncomfortable, and immediately the already smelly old face showed a wave of anger. Speaking of being suddenly interrupted at the most critical point, in the eyes of this central management cadre, it is no less than being forcibly terminated by someone driving a car with a beautiful woman. The **** turns 100% into anger, and he still doesn’t vent his anger. The kind of profit.

However, before he completely let his anger out, www.readwn.com immediately realized something, and quickly exclaimed in surprise: "What did you say? There are film cooling holes on the metal core? Didn't you just say that the entire blade is covered? Does it rely on ceramics to hard-eat the high-temperature jet from the combustion chamber?"

"Ceramic materials are indeed hard to eat high-temperature jets, but scientific common sense must be respected. Junior high school students know the common heat conduction effect. Don't you, a senior leading cadre who leads the navigation hair factory, knows it?

It should be known that the internal metal core is only a second-generation nickel-based alloy material, which can only withstand a high temperature of 850 degrees Celsius. If some cooling treatment is not done, the heat resistance of the ceramic material will be close to 900 degrees Celsius. "

"This...this...this..."

After hearing Zhuang Jianye’s words, the person in charge of the Hangfa Manufacturing Factory opened his mouth and wanted to say something, but before he could figure out what to say, Zhuang Jianye gave the metal core plug in his hand to the Hangfa Manufacturing. The person in charge of the factory asked unceremoniously: "Don't do this or that, just say, can the Japanese equipment make more than 1,800 special craft holes with a diameter of 0.15mm on the surface of a five-millimeter-thick complex blade? If so, we will buy as many such equipment as they have in Japan, and we will not hesitate to bankrupt our family!"
