Chapter Eighty-Four: The First Scrap
In Li Tianfeng's grand blueprint, this huge factory area of 1,200 acres will be built in multiple phases, and the construction time may last one or two years.
After completion, it will be an eye-catching aero engine production base, and will set up a precision machinery manufacturing center, a foundry engineering center, a material engineering center, an aero engine assembly center, an aero engine test center and so on.
In addition to these, there are also scientific research institutions, and the technology center of Tianfeng Technology Co., Ltd. will be established in the future, and the current process technology department will be incorporated into the technology center.
The technology center will include the process technology department, the aero engine design department, the real room, various research centers, etc., to provide services for the R&D, production and manufacturing of aero engines.
The precision machinery manufacturing center will have six precision machinery manufacturing workshops, all of which are the same large workshops as the first and second workshops, each workshop is a workshop of the same scale, the difference is that each workshop is engaged in precision machining of different types of aviation parts.
The foundry factory center has two large foundry workshops, engaged in the casting of various parts of aero engines, including precision casting of aero engine casing parts and blade parts.
Materials engineering center, this is Li Tianfeng must be established, because the domestic material level is limited, in the world can only be regarded as second-rate, and the gap is relatively large compared with advanced countries, in order to develop advanced aero engines, excellent all kinds of materials are essential.
It even includes some cutting-edge materials, such as new superalloy materials, titanium alloy materials, various composite materials, ceramic materials, carbon-based materials and so on.
Aero Engine Assembly Center......
Aero Engine Test Center......
……
Li Tianfeng's grand blueprint is very large, and the realization of this qiē will take one or two years at the earliest, these things are basically completed, and the huge, high-quality scientific research and technical team is also basically formed, and Li Tianfeng can start to develop his first aero engine.
In the minds of Li Tian and others, there are a large number of aero engine design materials, the latest and most cutting-edge aviation engine design and manufacturing concepts, etc., as well as various turboshafts, turbofan engine details and numbers, etc., some of which may be decades ahead of this era.
However, it is impossible to eat a fat man in one bite, only step by step, the research and development and manufacturing of aero engines, how can it be child's play, the research and development of the first aero engine, it is impossible to engage in a fifth-generation aircraft, a sixth-generation machine.
After all, it is impossible to start from scratch and build on the basic strength of Tianfeng Technology Company.
……
After looking at the No. 2 factory building, and Sun Kang went to see the technology center under construction, after looking at it for one or two hours, Li Tianfeng took a look at the time, there was still an hour before he got off work in the afternoon, and Li Tianfeng was going to go to the No. 1 workshop to have a look.
Entering the No. 1 workshop, I happened to see Zhang Can, the technical director of the workshop who was patrolling the scene, Li Tianfeng beckoned, and Zhang Can immediately trotted all the way over.
"Mr. Li, I just walked around the processing site, and it's basically normal." Zhang Can reported.
"Hmm." Nodding, Li Tianfeng said: "Let's go to Jin Youquan's CNC lathe to take a look, Jin Youquan is processing threads." ”
Zhang Can naturally understands that there is still a certain technical content for counting the threads, and the requirements for aero engine threads are relatively high, so the technical content is a little higher.
"Mr. Li, I happened to pass by Master Jin's CNC lathe just now, and the first bolt should have completed the thread counting process."
"Let's go, let's take a look." Li Tianfeng waved his hand.
The two walked towards the CNC lathe together, more than ten meters away from the CNC lathe, Zhang Can's eyes were sharp, and he saw Jin Youquan's brows locked, as if he was in trouble.
Seeing this, Zhang Can sighed in his heart, and thought to himself, "Is something wrong?" Thinking of this in his heart, Zhang Can's pace couldn't help but speed up a little.
At present, Tianfeng Technology Co., Ltd. undertakes these parts of factory E, those blank parts from factory E, as long as rough machining, semi-finishing, the difficulty is relatively low, as long as the workers operate in strict accordance with the process regulations, there will generally be no major problems.
In addition to the rough machining and semi-finishing of these blank parts, there are also some large and small bars from the E factory, which are basically used to process all kinds of bolts and nuts, because they have to be processed from the bar to qualified finished bolts and nuts, the technical content is slightly higher, and the difficulty is relatively large.
Fasteners for aero engines, even if they are just some bolts and nuts, are very demanding, not comparable to some civilian products, bolts and nuts for civilian products, you can buy them directly from the market, but these bolts and nuts used in aviation are not.
Not only can it not be purchased directly from the market, but it is also produced according to a strict production process, which is very demanding.
Li Tianfeng also found the abnormality, and also sped up his pace, and the two came to the CNC lathe together, and Zhang Can asked hurriedly: "Master Jin, what's wrong?" ”
Jin Youquan looked cramped and scratched his head, "Mr. Li, Director Zhang, there may be something wrong with the first part." ”
The thread of the first bolt has been turned, and Kim Youquan is checking the bolt with it, but the thread seems to be unqualified.
For the inspection of threads, there are professional inspection measuring tools, because the bolts are very small, there are many sizes, such as tooth shape, large diameter, small diameter, etc., these sizes, the general general measuring tools are difficult to measure, which requires the use of professional measuring tools.
What Jin Youquan is holding in his hand is a professional measuring tool for checking threads - thread gauge and stop gauge. The thread gauge can pass guò, and the thread stop gauge can not pass guò, which means that the processed thread is qualified, but the first thread processed by Jin Youquan can also pass guò if the thread stop gauge can also pass guò, which is obviously the thread is unqualified.
Taking this bolt and thread gauge and stop gauge from Jin Youquan's hand, Li Tianfeng's heart couldn't help but admire, the processed bolt is really beautiful, the bright bolt shines with the luster of metal, and there is no trace of burr on the surface, which is very smooth.
If it weren't for the unqualified inspection of the measuring tool, this is really a good product, this appearance, this appearance, even Li Tianfeng couldn't help but admire.
Zhang Can next to him also saw this beautiful bolt and couldn't help but admire: "Master Jin, the bolt is very beautifully processed, not bad!" ”
Jin Youquan is very modest, "Director Zhang, this is the processing process specification is very well prepared, as long as I strictly follow the process of processing, I can process such a product, there is no burr on the surface of the bolt, there is no need to polish at all, the CNC machining program will be cleaned when the bolt is processed, and the process specification is indispensable." ”
Hearing this, Li Tianfeng nodded, these processing technology regulations are all checked by Li Tianfeng personally, what Jin Youquan said is also the truth, as long as the processing skills of the workers are not too bad, and the processing is strictly in accordance with the process steps and parameters, such products will generally be processed.
After nodding, Li Tianfeng took the thread stop gauge and checked the thread, and if the thread stop gauge could be easily passed, it meant that the thread was unqualified.
"Master Jin, the large diameter and middle diameter of the thread are small, and if you want to adjust the knife, I think you need to add five wires to make up the knife." Li Tianfeng immediately found the crux of the problem.
"Okay, I'll adjust the knife repair right away." Jin Youquan said, and then said hesitantly: "Mr. Li, what about this bolt?" ”
Li Tianfeng didn't have to think about it, and immediately said: "This bolt is unqualified and scrapped, call the on-site inspector to come and open a scrap list, isolate it immediately, and this bolt will enter the waste area." ”
The processing of aviation parts is very strict, qualified products, unqualified products to be processed, waste products, etc., to be strictly isolated, there are also special areas for products to be processed, waste areas. Like this bolt, after scrapping, it cannot be mixed with the rest of the qualified products, it must be put into the scrap area immediately, and the bolt must also be clearly destructive.
Make an obvious destructive mark on the scrap, that is also a general method, in the processing process of aviation parts, it is generally done this, make such a mark, you can see at a glance that this is a scrap, it is impossible to mix with qualified products.
"Mr. Li, what should I do after this bolt is scrapped?" Jin Youquan asked hesitantly, obviously, what he was concerned about was that after scrapping, there would be one missing part.
However, Li Tianfeng doesn't have to worry, such small pieces such as bolts and nuts are generally a little more when feeding, and after scrapping one, it is okay to supplement and process one.
This kind of small pieces, and those large blanks are obviously different, those E factory is only responsible for processing rough processing, semi-finishing of large blanks, generally a radish a pit, one will not be more, one will not be less, how many pieces is how many.
Because it is a small piece, because there are materials, Li Tianfeng immediately said, "One more additional processing." ”
Seeing this, Jin Youquan breathed a sigh of relief, and then began the processing of the second bolt, when processing, in the program control panel of the CNC machine tool, the knife repair was changed to 5 wires, loaded the parts, carefully aligned, carefully aligned, and prepared for the processing of the second part.
