Chapter 121 No problem
"How is it possible? How can there be no problem? The problem is big." Wei Jiannan suddenly became anxious and his voice became louder several times.
"Minister Zeng, look at the length-to-diameter ratio of this milling cutter. The milling cutter is too long. If there is a tremor during the processing process or even a direct collapse, what's the matter? We are just a part of the overall blade plate, so we can't be careless."
This milling cutter is indeed longer. Generally speaking, the thinner the milling cutter, the worse the rigidity, the thicker the shorter the better the rigidity. Under normal circumstances, it is best to use a thick and shorter milling cutter, while this milling cutter is the opposite and looks relatively slender. No wonder Wei Jiannan almost jumped up.
Zeng Qinghai didn't want to argue. For the sake of Wei Jiannan's guest, Zeng Qinghai explained: "We have carefully considered it. The overall blade plate is relatively large and the blades are relatively long. It's really not possible if the milling cutter is short."
Even the rough milled blades have been carefully considered before. The processing plan was basically checked by Zeng Qinghai himself, and finally sent to Li Tianfeng for approval. There is basically no problem. Zeng Qinghai has this confidence.
"Warman, why not do this? Try it and you will know it by saying the truth." Zeng Qinghai said.
Wei Jiannan waved his hand quickly, "That's not possible. There's only one part. You actually want to give it a try. If something goes wrong, who will be responsible?"
This is not OK, that is not OK. Zeng Qinghai was obviously a little angry and said loudly: "I'm responsible, Master Qian, start the work after the processing is ready. I want to see how something goes wrong."
"You, you, are so arrogant!"
Wei Jiannan was very angry and left. Master Qian, who was preparing for processing, looked at Zeng Qinghai worriedly and said in a low voice, "Minister Zeng. He ran away when he was angry, and would not complain to President Li."
Zeng Qinghai waved his hand and said, "Let him, let's prepare and then process it."
The preparations before processing were actually done almost. I checked it briefly and then straightened the parts again. I felt that there was no problem, Master Qian closed the safety door of the large five-axis linkage machining center and gently pressed the start button.
The machine tool started working, and a few milky white coolant in the nozzle sprayed onto the parts. The machine tool spindle began to rotate, the speed became more and more high, and the parts also began to rotate on the indexing disc.
There are three coordinate movements of the machine tool spindle, namely up and down, front and back, left and right. It is also called "x, y, z". In addition, the indexing dial on the machine tool working platform carries the rotational movement of the parts, the machine tool platform's own flip movement, one or five movements, and can be linked at the same time, so it is called five-axis linkage.
There are already domestic five-axis machining centers in China, but there are almost no ones that can truly linkage. Basically, four-axis linkage can only be achieved, which is a technical gap between home and abroad. The five-axis linkage machining machine tools that process the overall blade disc are imported equipment, and the real five-axis linkage.
Such five-axis linkage is also called six-axis linkage in China, because some domestic machine tool manufacturers like to add the rotational movement of the machine tool spindle itself, and it becomes six-axis.
The spindle of the machine tool rotates very fast, which is a high cutting. As the machine tool spindle moves, the first milling cutter begins to cut parts, which is a corrugated alloy milling cutter with a diameter of 20 mm and a length of more than 120 mm.
This milling cutter is nearly 2,000 yuan, and the quality is excellent. Wei Jiannan just now actually said that there was something wrong with the milling cutter and his head was clamped by the door panel. Zeng Qinghai thought to himself.
In fact, Wei Jiannan only knows one thing, but not the second. The length-to-diameter ratio of this milling cutter exceeds 6, but the depth of cutting is not large, so the force it bears will not be large during cutting. In addition, this milling cutter is corrugated and the edges are corrugated.
The corrugated blade is a new design that can automatically cut off metal chips during the milling process. The milled metal chips are all fine "c"-type iron chips. Such "c"-type iron chips are washed clean by the cooling liquid and will not hinder processing at all.
Although this corrugated milling cutter is not very deep, it is very fast, which completely makes up for this and makes it look very efficient. On the parts, a deep groove gradually takes shape at a visible speed, and all processing is very stable.
The milling process next to the entire blade is very long. Just like this part, it takes two or three days to mill 24 hours a day. At the same time, there are various milling cutters used, including the corrugated milling cutters, conical milling cutters, ball head milling cutters, etc.
Zeng Qinghai couldn't keep watching here. After watching for half an hour, he saw that the processing was very stable and there was no abnormality. Zeng Qinghai also left the processing site and was about to come and take a look the next day.
Once the rough milling blades of the entire blade start processing, this five-axis linkage machining center will continue to process under the control of the CNC program, even in the middle of the night, all night long. Even if all the workers get off work, the machine tool is still working and processing.
The machine tool will automatically change the tool, and according to the control of the CNC program, it will automatically change the tool from the machine tool magazine. There is no need to worry, and there is no need to send workers to guard the night in the middle of the night.
Although the technical content of the blade is very high, this technical content is reflected in the process technicians, and it is not very high for operators. On the contrary, the workers who operate and process will be very relaxed.
Just like Master Qian who operates this five-axis linked CNC machining center, he is ready for processing. Once the processing starts, it is very easy. Sleeping next to him or playing with mobile phones. Of course, Tianfeng Technology has strict management. During working hours, especially at the production and processing site, it is absolutely not allowed to sleep or play with mobile phones.

office.
Li Tianfeng is thinking about the core engine design of the "tfwz" type turboshaft engine. This advanced turbine shaft engine with a power-to-weight ratio of 9 and an output power of 1800kw must be considered by Li Tianfeng himself.
"Bang!!!"
The door of his office was pushed open violently, and even Li Tianfeng was shocked and thought to himself, who is this, so bold.
Generally speaking, during working hours, the door of Li Tianfeng’s office will not be locked, but will only be hidden. When someone comes to his office, he will knock on the door first and then come in after being allowed. However, he does not knock on the door, pushing the door hard, and then breaking in.
Wei Jiannan!
Li Tianfeng looked up and immediately saw the person coming. Li Tianfeng had seen him this morning, but unexpectedly, Wei Jiannan broke into his office.
Since becoming the boss, Li Tianfeng seems to have improved his cultivation, and he is not angry. He said calmly: "Mr. Wei, is there anything wrong?"
Wei Jiannan immediately said with dissatisfaction: "Mr. Li, the overall blade plate has started rough milling and blade processing. I went to see it with Minister Zeng just now..."
After listening to Wei Jiannan's speech, Li Tianfeng couldn't help but smile, "Waiting, drink a cup of tea first." After that, Li Tianfeng signaled Liu Wei, who had just come in, to pour Wei Jiannan a cup of tea.
Obviously, when Liu Wei heard the news, she came over immediately. Upon hearing this, Liu Wei poured a cup of tea, then hid the door and retreated.
Wei Jiannan drank the cup of warm tea in one breath and said, "Mr. Li, this is really not enough, there will be big problems with the processing."
Li Tianfeng gave a look of peace and smiled softly: "Waiting, don't worry, there is no problem. In this way, there are several good attractions in our Songzhou. I will arrange someone to take you to have fun and relax."
Wei Jiannan had no intention of traveling around the country and rivers. When he saw Li Tianfeng, he didn't believe there would be any problems. He knew that it would be useless to continue talking, so he left angrily.
Li Tianfeng smiled and was obviously very confident in the rough milling of the blades. Seeing that Wei Jiannan had left, Li Tianfeng did not take it seriously and continued to think about some things in the design of the "tfwz" type turboshaft engine.
Not long after, the cell phone placed on the desk vibrated. Li Tianfeng picked it up and saw that it was Long Yingshi who called him in Factory B. Li Tianfeng thought to himself, the speed was really fast. Obviously, Wei Jiannan Xianglong Yingshi responded to the situation. To put it bluntly, he complained.
"Mr. Li, I just heard from the sanitation worker's reaction to some situation..."
Li Tianfeng interrupted Long Yingshi's words and said with a smile: "Mr. Long, don't worry, there is no problem, everything is processed normally. In two days, you will ask the ward to go to the processing site to take a look at it yourself, don't worry!"
Seeing that Li Tianfeng was so confident, Long Yingshi didn't say anything. The two chatted for a while and hung up the phone.
Li Tianfeng personally reviewed the blade rough milling process, even the CNC program is the same. Li Tianfeng really doesn’t worry about any problems.
………
Getting off work is approaching.
Li Tianfeng felt that there was a text message on his mobile phone. He took it out and saw that it was sent by Ouyang Feifei. After reading the text message, Li Tianfeng was happy. This little girl has become more and more proactive recently. So, she asked me to go shopping after getting off work.
Thinking about it, there was no social engagement at night, Li Tianfeng smiled slightly, replied to the little girl with a text message, and promised that the two of them would go shopping together in the evening.
Li Tianfeng thought to himself, the little girl is so proactive, maybe something will happen tonight, and Li Tianfeng had a little premonition in his heart.
After the time for get off work, because today is Friday again, the employees happily started to get off work, and Li Tianfeng also sorted out the documents on his desk.
"Brother Li, are we going to set out now?"
Outside the door, Ouyang Feifei was walking in with a happy look on her face, and had already changed out of her work clothes and looked beautiful. Li Tianfeng thought to himself that Feifei seemed to be getting more and more beautiful.
In fact, Ouyang Feifei is already beautiful, and recently, she has paid special attention to dressing up herself. In addition, the nourishment of love makes her really beautiful.
