In the office, Li Tianfeng solemnly explained many things to Yang Zhan and did not dare to take them lightly at all.△ On the contrary, Li Tianfeng attached great importance to them.

Yang Zhan also knew the importance of the matter and did not dare to be negligent at all. He remembered everything Li Tianfeng told him one by one. Today, there are still several days before the second party review officially begins, so no matter what, he will have to attack.

The first thing is to do is to check your own problems. No matter how big or small the problem is, you will correct it immediately as long as you find the problem. There are still a few days left. I hope to check for omissions and fill in the gaps and try to find fewer problems when the other party comes to Tianfeng Technology for review.

As for not finding any problem, it seems very difficult. I have never heard of any reviewed unit after strict personal review, but in the end no problem was found.

After explaining many things to Yang Zhan, Li Tianfeng said: "Minister Yang, act quickly. If you have any questions, you can directly contact me. I will support you with all my support!"

Yang Zhan nodded, turned around, and walked out of the office quickly. It was obvious that he started this matter immediately. He watched Yang Zhan leave. Li Tianfeng nodded solemnly and thought to himself that there must be no problems with the second party review this time.

In the next few days, Li Tianfeng will focus on this second-party review that will be about to begin. Secondly, as long as you have a little time, Li Tianfeng will still pay attention to the development of his "tfwz001" turboshaft engine and begin to prepare for the air show.

The development of the "tfwz001" type turboshaft engine is basically smooth. Although some small problems occur every day, the overall process is not affected, and these small problems are solved one by one.

A week passed quickly. When he went to work on Monday, Li Tianfeng inspected the entire company as usual. Seeing that the four major workshops were in full swing, the construction of workshops No. 5 and No. 6 was also progressing very quickly, Li Tianfeng felt more relieved.

Since he had bet with Wang Guohong for three years, Li Tianfeng has been under great pressure. At the same time, he breathed a sigh of relief and did not dare to relax at all about the development of the "tfwz001" turboshaft engine and the infrastructure of Tianfeng Technology Company. On the contrary, he has always put in full force.

Workshop No. 5 mainly produces various types of sheet metal parts and welded parts. Workshop No. 6 mainly produces various types of fasteners and parts. After these two workshops are built, the production capacity will rise to a big step, especially Workshop No. 5, 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 aviation engine roulette and shaft parts.

Workshop No. 2 mainly produces various receiver parts.

Workshop No. 3 will mainly produce various types of aircraft engine blades.

Workshop No. 4 will mainly produce various structural parts.

Workshop No. 5 mainly produces various types of sheet metal parts and welded parts.

Workshop No. 6 mainly produces various fasteners and parts.

There are six cold machining workshops, including hot processing workshops, No. 7 workshops mainly cast, No. 8 workshops mainly surface treatment, No. 9 workshops mainly forged, etc.

Each workshop has a clear product positioning. This is equivalent to professional production. A workshop mainly specializes in the production of the same type of parts, which is of great help to technical management, technical improvement, etc.

The huge factory building in the No. 5 and No. 6 workshop has been topped off, and supporting facilities are underway, such as power, ventilation, waterways, etc. It is estimated that it will be officially put into use in the past two or three months.

In addition, the construction of the final assembly workshop, test workshop, logistics warehouse, finished product accessories warehouse, etc. is also being fully launched. In addition to the difficulty of construction of the test workshop, the rest should be fully completed before the end of this year.

By then, the entire Tianfeng Technology Company will be completely renewed, and the shotgun will be replaced with cannons. It will no longer look like it now. It will gradually become a professional aviation engine company, integrating R&D, testing and manufacturing.

I visited several major workshops and went to the technical center. When I returned to my office, the whole morning was almost over.

The company is so big, it’s really tiring to patrol like this. Sitting on his boss’ chair, Li Tianfeng thought to himself.

"Dingling..."

The phone on the desk rang out in a hurry. Li Tianfeng answered the phone and said aloud: "Hello, I am Li Tianfeng."

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

Li Tianfeng said: "Mr. Yang, what's the situation?"

Yang Xianfeng sighed and said, "It's so stressful. I just started the review and found out that our three general unqualified items were really a headache."

Hearing this, Li Tianfeng was silent and began to review three issues. It seems that this review team is not ordinary, at least it is very good at finding faults.

Yang Xianfeng continued: "By the way, Tianfeng Technology will be reviewed on Wednesday morning. Two people will come over. After a long period of review, Tianfeng must not let them examine serious unqualified items, otherwise it will be very troublesome."

The issues found for review are divided into three levels: general unqualified items, serious unqualified items, major unqualified items, and general unqualified items that were examined were slightly better. They can generally pass after rectification. However, if it is serious unqualified items, it will be very troublesome. If it is a major unqualified item, then it will be completely finished.

Li Tianfeng said: "We are speeding up our internal audit and rectify the problem immediately when we find it."

Yang Xianfeng nodded: "There are more than a dozen machinery manufacturing companies that have business relationships with our e-factory. I am quite at ease with Tianfeng Technology. Tianfeng, I will bring them here in person on Wednesday. If I can help you some things, I will do my best to help you."

"Mr. Yang, then thank you."

"Tianfeng, why are we polite? Then I'll say that we'll see you on Wednesday morning."

"Yeah, goodbye."

After hanging up the phone, Li Tianfeng thought to himself that Yang Xianfeng is quite good and is more helpful to him. He is considered a true friend of his.

Technology Center, Aero Engine Design Institute.

Li Tianfeng and Qiu Wen'an are together. On the computer screen, the combustion chamber receiver of the "tfwz001" type turboshaft engine is a three-dimensional figure. The combustion chamber receiver and flame cylinder are both important and key parts of the combustion chamber part of the aircraft engine.

The flame tube has already completed the design work and is currently underway. The design progress of the combustion chamber receiver is a little later. At this time, the design has been basically completed. The two are discussing some details, saying that it is a discussion, and basically Qiu Wen'an is humbly asking for advice.

"Boss, there are two sets of design plans for the combustion chamber receiver. The first set is designed as sheet metal parts, mainly using stamping and welding processes, and the second set uses forging cutting technology, and a forging blank is processed bit by bit by bit.

These two design plans have their own advantages and disadvantages. The first design plan is suitable for large-scale mass production, and the second design plan is suitable for fine work.

Li Tianfeng pondered for a moment and said, "My personal opinion is to adopt the first solution. Our "tfwz001" type turboshaft engine must consider mass production from the design, and use stamping and sheet metal welding, which is the most suitable."

Qiu Wen'an said worriedly: "Boss, will the use of stamping and sheet metal welding affect the quality?"

Li Tianfeng smiled and said, "No, you must fully believe in your design level. Come on, let's focus on the first design plan."

During World War II, the famous Thomson submachine gun initially used mechanical cutting parts, which had high processing costs and a long production cycle. Later, stamping parts were widely used, which not only did the cost decrease, but the production cycle was greatly shortened. Moreover, the production batches could surge, reaching the production scale of millions.

The "tfwz001" type turboshaft engine is positioned as the power of an armed helicopter. It must consider the production cost and the situation in case of war. Inflammable receivers, turbine receivers, etc., Li Tianfeng is preparing to widely adopt stamping and sheet metal welding designs to facilitate future large-scale production.

Such designs, as long as they are designed properly and fully considered, will not affect the quality, because stamping and sheet metal welded parts can also be processed very precisely. For example, after welding, mechanical processing can be carried out, and some precision positioning holes and high-precision installation planes can be fine-processed to fully meet the design requirements.

Seeing Li Tianfeng say this, Qiu Wen'an nodded. In Qiu Wen'an's heart, as long as Li Tianfeng checks the design, he will be full of confidence.

The two discussed the first design plan for a long time. Li Tianfeng put forward many very useful suggestions on the design, and even mentioned some new design concepts and ideas. After this discussion, Qiu Wen'an found that he was very rewarding, at least he gained a lot in the design of the combustion receiver.

Qiu Wen'andao: "Boss, based on your improvement opinions, I will immediately organize the design of the combustion chamber receiver to improve and perfect the design."

Li Tianfeng nodded: "After the design is completed, I will give it to me to see. If there is no problem, you can draw a picture and then start the processing of the first combustion chamber receiver."

"Okay, I should be able to complete the improvement and improvement this week. Once it is completed, I will send it to the boss for review immediately."

Wednesday morning.

The second-party review expert team will review Tianfeng Technology Company today. At around 8:30 in the morning, a Mercedes-Benz business car drove over from Songzhou Avenue and stopped at the gate of Tianfeng Technology Company. The first person to get off the bus was Yang Xianfeng, and then the person to get off the bus was an old man in his sixties, wearing glasses and gray hair.
