In the office, Li Tianfeng solemnly explained many things to Yang Zhan, and he didn't dare to take it lightly at all. On the contrary, Li Tianfeng attaches great importance to it.

Yang Zhan also knows the importance of the matter, where can he dare to be a little lazy, Li Tianfeng has all the things he has explained in his heart, today is still a few days before the official start of the second-party review, no matter what, he has to surprise it.

The first is self-inspection, find all kinds of problems by yourself, no matter how big or small, as long as you find problems, you will immediately rectify them, and there are still a few days to do so, hoping to check and fill in the gaps, and strive for the other party to find fewer problems when you come to Tianfeng Technology to review.

As for not finding a problem, this seems to be very difficult, and I have never heard of a unit that has been censored, and after a strict personal inspection, no problems have been found in the end.

After explaining a lot of things to Yang Zhan, Li Tianfeng said: "Minister Yang, hurry up, if you have any questions, you can contact me directly, I fully support it!" ”

Yang Zhan nodded, turned around, and walked out of the office quickly, obviously starting this matter immediately, seeing Yang Zhan leave, Li Tianfeng nodded solemnly, and thought in his heart, there must be no problems in this second-party audit.

In the next few days, Li Tianfeng's main focus is on the upcoming two-party audit, and secondly, as long as he has a little time, Li Tianfeng will still pay attention to the development of his "TFWZ001" turboshaft engine, and begin to prepare for participating in the air show.

The development of the "TFWZ001" turboshaft engine was basically smooth, although there were some small problems every day, but the overall process was not affected, and these small problems were solved one by one.

A week passed quickly, and when he went to work on Monday, Li Tianfeng went to the entire company to inspect the whole company as usual, and saw that the four major workshops were all hot, in addition, the construction of the fifth and sixth workshops was also progressing rapidly, and Li Tianfeng was more relieved.

Since he gambled with Wang Guohong for three years, Li Tianfeng has been very stressed, and at the same time, he has breathed a sigh of relief in his heart, and he has not dared to relax at all about the development of the "TFWZ001" turboshaft engine and the infrastructure construction of Tianfeng Technology Company.

The No. 5 workshop mainly produces all kinds of sheet metal parts and welded parts. The No. 6 workshop mainly produces all kinds of fasteners and all kinds of parts. After the completion of these two workshops, the production capacity will go to a big step, especially the No. 5 workshop, which will be a professional processing workshop for all kinds of sheet metal parts and welded parts.

According to the plan, the No. 1 processing workshop mainly processes aero engine wheel discs and shaft parts.

The second workshop mainly produces all kinds of casing parts.

Workshop 3 will mainly produce various types of blades for aero engines.

Workshop 4 will mainly produce various types of structural parts.

The No. 5 workshop mainly produces all kinds of sheet metal parts and welded parts.

The No. 6 workshop mainly produces all kinds of fasteners and all kinds of parts.

The cold machining workshop is planned to be six, in addition to the hot processing workshop, the No. 7 workshop based on casting, the No. 8 workshop based on surface treatment, the No. 9 workshop mainly forging, and so on.

Each workshop has a clear product positioning, which is equivalent to specialized production, a workshop is mainly dedicated to the production of the same type of parts, which is of great help to technical management and technology improvement.

The huge plant of the fifth and sixth workshops has been capped, and the construction of supporting facilities is underway, such as electricity, ventilation, waterway construction, etc., and it is estimated that it will be officially put into use in the last two or three months.

In addition, the assembly workshop, the test workshop, the logistics warehouse, the finished parts warehouse and so on are also in full swing construction, in addition to the test workshop construction is more difficult, the rest should be fully completed before the end of this year.

At that time, the entire Tianfeng Technology Company will take on a new look, and the shotgun will no longer be the same as it is now, and it will gradually become a professional aero engine company, integrating R&D, testing and manufacturing.

After a round of several major workshops, I went to the technical center again, and when I returned to my office, the whole morning was almost over.

The company is so big, and it's really tiring to make such a round. Sitting in his boss's chair, Li Tianfeng thought in his heart.

"Jingle Bell ......"

The phone on the desk rang with a rapid ringtone, Li Tianfeng picked up the phone, and said loudly: "Hello, I'm Li Tianfeng." ”

Yang Xianfeng's voice came from the phone: "Tianfeng, it's me, the second-party audit team has entered our E factory today, and immediately started the review work, a total of six people, divided into three audit teams." ”

Li Tianfeng said: "Mr. Yang, how is the situation?" ”

Yang Xianfeng sighed and said: "It's a lot of pressure, we just started the review, and we found three general non-conformities, which is really a headache." ”

Hearing this, Li Tianfeng was silent, and just after the review began, three problems were examined, and it seems that this review team is not ordinarily powerful, at least it is very good at finding faults.

Yang Xianfeng continued: "By the way, on Wednesday morning, Tianfeng Technology will be reviewed, and two people will come over to review it for half a day, Tianfeng, don't let them review the unqualified items, otherwise, it will be very troublesome." ”

The problems that come out of the review are divided into three levels, general non-conformities, strict non-conformities, heavy dà unqualified items, and the general non-conformities that are reviewed are slightly better, and they can generally pass guò after rectification, but if it is a strict non-conformity, it will be very troublesome, and if it is a heavy dà non-conformity, then it will be completely finished.

Li Tianfeng said: "We are stepping up our own internal audit, and we will rectify the problems immediately when we find them. ”

Yang Xianfeng nodded: "There are more than a dozen machinery manufacturing companies that have business relations with our E factory, Tianfeng Technology, I am more assured, Tianfeng, I will personally bring them over on Wednesday, if there are some things that can help, I will try my best to help you." ”

"Mr. Yang, thank you then."

"Tianfeng, what is polite between us, then let's say okay, see you on Wednesday morning."

"Well, goodbye."

After hanging up the phone, Li Tianfeng thought in his heart, Yang Xianfeng's personality is still good, and he is also more helpful to himself, and he can be regarded as a real friend of himself.

Technical Center, Aero Engine Design Institute.

Li Tianfeng and Qiu Wenan were together, and on the computer screen, it was the combustion chamber casing of the "TFWZ001" turboshaft engine, and it was a three-dimensional three-dimensional pattern. The combustion chamber casing and flame barrel are all important and key parts of the combustion chamber part of the aero engine.

The flame tube has already completed the design work, at present, the processing is being carried out, the design progress of the combustion chamber casing is a little late, at this time the design has been basically completed, the two are discussing some details, saying that it is a discussion, basically Qiu Wenan is humbly asking for advice.

"Boss, there are two sets of design schemes for the combustion chamber casing, the first set is designed for sheet metal parts, mainly using stamping and welding processes, and the second set uses the forging cutting process, which processes a forging blank through guò machining and processing it little by little.

These two sets of design schemes, each has its own advantages and disadvantages, the first set of design schemes, suitable for large-scale mass production, the second design scheme is suitable for fine work.

Li Tianfeng sighed and said: "My personal opinion is to adopt the first set of schemes, our "TFWZ001" turboshaft engine must be designed to consider mass production, using stamping and sheet metal welding, which is the most suitable. ”

Qiu Wenan said worriedly: "Boss, the use of stamping and sheet metal welding will not have an impact on the quality." ”

Li Tianfeng said with a smile: "No, you have to fully believe in your own design level, come, let's focus on the first set of design schemes." ”

During World War II, the famous Thomson submachine gun initially used mechanical cutting parts, the processing cost was very high, and the production and manufacturing cycle was relatively long.

The turboshaft engine of the "TFWZ001" type is positioned as the power of a helicopter gunship, and it is necessary to consider the cost of production, as well as the situation in the event of war. Burning casings, turbine casings, etc., Li Tianfeng is ready to widely adopt stamping and sheet metal welding designs to facilitate large-scale production in the future.

Such a design, as long as the design is properly considered, fully considering the manufacturability, will not affect the quality, because stamping and sheet metal welding parts, can also be processed very precisely, such as after the welding is completed, the machining can be carried out, some precision positioning holes, high-precision installation planes can be finished, fully meet the design requirements.

Seeing Li Tianfeng say this, Qiu Wenan nodded, in Qiu Wen'an's heart, as long as Li Tianfeng checked the design, he was full of confidence.

For the first set of design schemes, the two discussed for a long time, Li Tianfeng put forward a lot of very useful suggestions for improvement in the design, and even said some new design concepts and ideas, so after a discussion, Qiu Wenan found that he had gained a lot, at least in the design of the combustion casing.

Qiu Wen'an said: "Boss, according to your suggestions for improvement, I will immediately organize the improvement of the design of the combustion chamber casing." ”

Li Tianfeng nodded: "After the design is completed, send it to me to see, if there is no problem, you can produce the drawing, and then start the processing of the first combustion chamber casing." ”

"Okay, it should be done this week, and once it's done, I'll send it to my boss for review."

………

Wednesday morning.

The two-party audit expert team will audit Tianfeng Technology Company today, at about half past eight in the morning, a Mercedes-Benz business car drove from the direction of Songzhou Avenue, stopped at the gate of Tianfeng Technology Company, the first to get off is Yang Xianfeng, and then got off is an old man who is nearly sixty years old, wearing glasses and full of gray hair.
