Start with the aviation industry

Chapter 66
Factory office building, reception room.

The steaming hot tea was brought up one by one. Xiao Liu, who was in charge of making the tea, was a little nervous. After putting a cup of hot tea in front of everyone, he quietly withdrew.

When he got outside the reception room, Xiao Liu quietly let out a sigh of relief, my God, it's really unusual for so many leaders to come!
She works as a receptionist, and this kind of scene rarely happens a few times a year. The standard here is a bit high today.

Although there were not many people in the reception room, just a dozen or so people, almost all of them were big bosses.

For the Phoenix factory, Wang Tianfang, the deputy director and chief engineer, and Meng Bowen, the deputy director of production.

Phoenix Aero-Engine Design Institute is headed by Zeng Zhihong.

There are five or six people in the military, including Zhong Zimin, the representative of the general army stationed in Fenghuang Factory, and Feng Shuiqing, the representative of the deputy general army.

This is not the highest level, Zhang Fenjin, the head of a new type of missile with the highest level, came in person.

Zhang Fenjin and his party first went to the Phoenix Aero-engine Design Institute to investigate the relevant situation and progress, and now they have arrived at the Phoenix Factory with only one purpose, that is, the design and development of a new type of missile.

"Everyone, I won't talk about the importance of this type of missile. Our military has also put forward very high requirements on the performance of the missile, including its engine."

Zhang Fenjin personally introduced the situation of the missile, and then his face straightened, "We are quite satisfied with the design progress. Many parts have entered the design verification work, including the turbine part will also enter the design verification."

"The turbine design has been greatly improved this time. It is no longer precision casting, but milling of the overall blade. I am not worried about its performance at all. What I am worried about is its manufacturing."

"I know that the machining difficulty of this turbine disk lies in the machining of the blades. I am worried about its machining quality and its machining efficiency."

Quality is one aspect, but also processing quantity.

It is not like an aero engine, which produces a dozen or dozens of units a year, but at least hundreds of them a year.

Zhong Zimin took over the topic, obviously also worried about this aspect, "The milling efficiency of blades is generally not high. I estimate that the milling of a whole turbine disk blade may take as long as dozens of hours."

Dozens of hours, that is, maybe two or three days.

It does take so long for many integral blade discs. In addition, few factories in China have the processing capacity of integral blade discs.

It not only requires high precision, but also requires five-axis linkage CNC machine tools. In 1990, there were not many such machine tools in the whole country.

Seemingly aware of the military’s concerns, Wang Tianfang said, “Our Phoenix Factory will undertake the milling of the blades for the overall turbine disc used for design verification. We will know how long it will take, and we will also have it in mind. A reference."

The meaning is obvious, how long the processing time is required can be seen through the processing of these three integral turbine disks.

Zeng Zhihong added, "Boss Wang is right. We will soon know how long it will take. We have already sent three integral turbine disks to workshop 406."

The leaders were drinking tea in the reception room of the factory office building, while discussing the future processing of the overall turbine disk, while Lin Feng sat in front of his computer, earnestly programming.

Finally compiled.

Lin Feng carefully checked the NC program with hundreds of lines and thought there was nothing wrong with it, so he saved it in a [-]-inch floppy disk.

The [-]-inch floppy disk is the main carrier. Now there are no USB flash drives, mobile hard disks and the like. After the program is compiled, it is copied into the CNC machine tool at the production site through the [-]-inch floppy disk.

The NC program is done, and the processing can be carried out as soon as the NC tool arrives.

Lin Feng raised his hand to check the time, he would be off work in less than 10 minutes, where should he go for a bite to eat after get off work, should he go to the staff canteen in the factory, or go to a restaurant.

He had money in his pocket, and it was quite a lot. Lin Feng's appetite was getting worse and worse. The food in the cafeteria could hardly satisfy his mouth. Now he needed to eat meat every now and then.

Thinking about where to eat after get off work.

"Boom, boom, boom."

There was a knock on the door of the office. Who was it? Lin Feng was rather puzzled. If it was someone from Workshop 406, there were very few people who knocked on the door so politely.

"Come in, the door is unlocked."

The one who gently opened the door was a young man who looked less than 30 years old. He pushed the door halfway open, leaned out half of his body, and asked cautiously.

"You are a forest worker, right?"

"Yes, I am Lin Feng."

Hearing this, the young man breathed a sigh of relief, walked in and said, "Gong Lin, I brought you something."

Good guy, it looks like there are quite a lot of things!
There is a handbag in his hand, which is bulging and looks very heavy.

The young man said, "I'm from Phoenix Institute. I'll send you the design drawing of the whole turbine disk and the tools you need."

While talking, he took out things from his bag and put them on the table one by one.

The first is the design drawing of the overall turbine. He thinks this is the most important. If the parts need to be processed, they must be programmed. Lin Feng must read this drawing.

What he didn't know was that Lin Feng had already firmly memorized the contents of the blueprint in his head, and he had already compiled the CNC program, so there was no need for the blueprint at all.

However, since it was sent all the way, Lin Feng accepted it politely, and spread out the design drawing on the big table. After looking at it for a while, it was a brand new design drawing, which still smelled pungent. The taste is probably fresh orchid.

Then there are those alloy knives.

There are a total of five types of alloy milling cutters, all of which were designed by Lin Feng. There are a dozen of each of them, wrapped in waste newspapers.

The young man put these alloy milling cutters on the table one by one, "Gong Lin, all the cutters you designed are ready, take a look."

So fast!
Lin Feng was slightly surprised, originally thought it would take ten days and half a month, but actually finished it all in one week and delivered it to him.

Opening the wrapped newspaper, Lin Feng picked up one of the milling cutters and looked at it.

Soon he nodded in satisfaction. He didn't know which knife factory Fenghuang had found to make the knife. The quality of the knife was very good, and it was also beautifully made.

The young man said, "Gong Lin, I have already delivered the things to you. In addition, the three integral turbine discs have also arrived at your production site. I would like to ask when you can start processing."

He hoped that the sooner the better, not only him, but Zeng Zhihong probably meant the same thing.

Lin Feng replied, "Since everything is ready, we can start processing the first piece tomorrow morning."

tomorrow morning!

The young man immediately showed a look of surprise, and said in addition to being happy, "Gong Lin, I will work hard for you."

He thought that Lin Feng might work overtime tonight, for example, he needed to compile the CNC machining program. What he didn't know was that the CNC program had already been compiled.

After obtaining the exact time, the first piece of processing can be started tomorrow morning, and he left happily.

　Guys, help me to cast a few recommendation votes, the number of recommendation votes is really a bit small!
