"How is that possible? How can there be no problem? Big problem. Wei Jiannan was immediately anxious, and his voice was a few degrees louder.

"Minister Zeng, you take a look at the length-to-diameter ratio of this milling cutter, the milling cutter is too long, in case of tremor during the machining process, or even direct collapse, then how can we get it, we are such a part of the integral blade disc, we can't be sloppy."

This milling cutter is indeed longer, generally speaking, the more slender the milling cutter, the worse the rigidity, the thicker and shorter, the better the rigidity, under normal circumstances, it is best to use a stubby milling cutter, and this milling cutter is the opposite, it seems more slender, no wonder Wei Jiannan almost jumped up.

Zeng Qinghai didn't want to argue, for the sake of Wei Jiannan is face as a guest, Zeng Qinghai explained: "Wei Gong, we have carefully considered, this overall blade disc is relatively large, the blade is relatively long, and the milling cutter is really not good." ”

Even if it is rough milling blades, it has been carefully considered before, and the processing plan is basically checked by Zeng Qinghai himself, and finally sent to Li Tianfeng for approval, basically there will be no problem, Zeng Qinghai has this confidence.

"Wei Gong, if it's not like this, the facts speak, just try it and find out." Zeng Qinghai Road.

Wei Jiannan hurriedly waved his hand, "That's not good, the parts are just like this, you actually want to give it a try, if something goes wrong, who is responsible?" ”

This is not good, that is not good, Zeng Qinghai was obviously a little angry, and said loudly: "I'm responsible, Master Qian, I'll start work when I'm ready for processing, I want to see how something goes wrong." ”

"You, you, too arrogant!"

Wei Jiannan was very angry, brushed his sleeves away, and Master Qian, who was preparing for processing, glanced at Zeng Qinghai worriedly, and whispered, "Minister Zeng." He ran away angrily, so he wouldn't go to Mr. Li to complain. ”

Zeng Qinghai waved his hand and said, "Let him be, we will prepare, and then process." ”

In fact, the preparation work before processing is almost done, check it a little, and find the parts again. Feeling that there was no problem, Master Qian closed the safety door of this large five-axis linkage machining center, and then gently pressed the start button.

The machine began to work, several milky white coolant in the nozzle sprayed on the parts, the machine spindle began to rotate, the speed became more and more open, and the parts began to rotate on the index dial.

The movement of the machine tool spindle has a total of three coordinates, namely up and down, front and back, left and right. It is also called "X, Y, Z" three coordinate directions, plus the rotary movement of the indexing plate with parts on the machine tool working platform, the machine tool platform's own flipping motion, a five-movement, 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 wood that can be linked in real time. Basically, it can only achieve four-axis linkage, which is a technical gap at home and abroad. The five-axis linkage processing machine tool for processing this integral blade disc is imported equipment, and it is a real five-axis linkage.

Such a five-axis linkage is also called six-axis linkage in China, because some domestic machine tool factories like to add the rotary motion of the machine tool spindle itself, which becomes a six-axis.

The spindle of the machine tool rotates very fast, which belongs to the high degree of cutting. With the movement of the spindle of the machine tool, the first milling cutter begins to cut the parts, which is a corrugated alloy milling cutter with a diameter of 20 mm and a length of more than 120 mm.

Such a milling cutter is nearly 2,000 pieces, and the quality is excellent. Wei Jiannan just now actually said that there was a problem with this milling cutter, and his head was clamped by the door panel. Zeng Qinghai thought so in his heart.

In fact, Wei Jiannan only knows one of them, but does not know the second, the length and diameter ratio of this milling cutter is more than 6, but the depth of cut is not large, the depth of cut is not large, and the force will not be large when cutting.

The corrugated cutting edge, a new design, automatically cuts off the metal chips during the milling process, and the milled metal chips are all fine "C" iron chips, which are washed clean by the coolant and do not hinder the processing at all.

Although the depth of cut of this corrugated milling cutter is not large, but the speed is very fast, which completely makes up for this, and the processing efficiency is very high.

The milling process next to the integral blade takes a very long time, just like this part, 24 hours a day continuous milling, but also two or three days, at the same time, the milling cutter used is also various, there are just a corrugated milling cutter, as well as a conical milling cutter, as well as a ball nose milling cutter and so on.

Zeng Qinghai couldn't keep watching here, after watching for more than half an hour, he saw that the processing was very stable and there was no abnormality, Zeng Qinghai also left the processing site, preparing to come and have a look again the next day.

The rough milling blade of the integral blade, once the processing begins, this five-axis linkage machining center will be under the control of the CNC program, and it will continue to be processed, even at night, in the middle of the night, all night long, even if the workers are all off work, this machine tool is also working and processing.

The machine tool will automatically change the tool, according to the control of the CNC program, automatically change the tool from the machine tool magazine, don't worry, and there is no need to send workers to guard in the middle of the night.

CNC milling of blades, although the technical content is very high, but the technical content is reflected in the process technicians, for the operators, it is not very high, on the contrary, the workers who operate the processing will be very easy.

Just like the master Qian who operates this five-axis linkage CNC machining center, ready for processing, once the processing is started, it is very easy, sleeping next to it, playing with mobile phones, of course, Tianfeng Technology has strict management, working hours, especially in the production and processing site, it is absolutely not allowed to sleep, play with mobile phones.

Office.

Li Tianfeng is thinking about the design of the core engine of the "TFWZ" turboshaft engine, which has a power-to-weight ratio of 9 and an output of 1800kW advanced turboshaft engine.

"Bang !!"

The door of his office was violently pushed open, and even Li Tianfeng couldn't help but be startled, thinking in his heart, who is this, so bold.

Under normal circumstances, during working hours, the door of Li Tianfeng's office will not be locked, it will only be concealed, and when someone comes to his office, he will knock on the door first, and then come in after getting permission.

Wei Jiannan!

Li Tianfeng raised his head and immediately saw the person who came, this morning, Li Tianfeng had seen it, but he didn't expect Wei Jiannan to break into his office.

Since becoming the boss, Li Tianfeng's cultivation seems to be getting better and better, and he is not angry, and said calmly: "Wei Gong, is there something?" ”

Wei Jiannan immediately said dissatisfiedly: "Mr. Li, the overall blade disc has begun rough milling blade processing, I went to see the ...... with Minister Zeng just now."

After listening to Wei Jiannan's speech, Li Tianfeng couldn't help but smile, "Wei Gong, drink a cup of tea first." After speaking, Li Tianfeng motioned to Liu Wei, who had just come in, to pour Wei Jiannan a cup of tea.

Obviously, Liu Wei heard the movement and immediately came over, and when she heard this, Liu Wei poured a cup of tea, and then retreated from the door.

Wei Jiannan drank the cup of warm tea in one go, and then said: "Mr. Li, it really can't go on like this, there will be big problems in processing." ”

Li Tianfeng gave a slightly calm look, and smiled lightly: "Wei Gong, don't worry, there is no problem, in this way, we have a few good attractions in Songzhou, I will arrange someone to take you to play and relax." ”

Where did Wei Jiannan have the heart to travel in the mountains and rivers, seeing that Li Tianfeng didn't believe that there would be a problem, and he knew that it was useless to keep talking, so he left angrily.

Li Tianfeng smiled, obviously very confident in the rough milling of the blade, seeing that Wei Jiannan was gone, Li Tianfeng did not take it to heart, and continued to think about some things in the design of the "TFWZ" turboshaft engine.

It didn't take long for the mobile phone on the desk to vibrate, Li Tianfeng picked it up and saw that it was actually Long Yingshi from Factory B, Li Tianfeng thought in his heart, the speed is really fast, obviously, Wei Jiannan reacted to the situation to Long Yingshi, and if it was not good, it was a complaint.

"Mr. Li, I just heard Wei Gong react to some situations......

Li Tianfeng interrupted Long Yingshi's words, and said with a smile: "Mr. Long, you can rest assured, there is no problem, the processing is normal, in two days, you call Wei Gong to go to the processing site to take a look in person, rest assured!" ”

Seeing that Li Tianfeng was so confident, Long Yingshi didn't say anything, and the two hung up the phone after chatting for a while.

Rough milling of blades, this process Li Tianfeng personally approved, even the CNC program of processing is the same, Li Tianfeng really doesn't worry about what will go wrong.

………

It's about to end at work.

Li Tianfeng felt that there was a text message on his mobile phone, and when he took it out, he saw that it was sent by Ouyang Feifei, after reading the text message, Li Tianfeng was happy, this little girl, has been getting more and more active recently, no, he asked himself to go shopping after work.

Thinking about it, there was no entertainment at night, Li Tianfeng smiled slightly, and sent a text message back to Xiao Nizi, promising that the two of them would go shopping together in the evening.

Li Tianfeng thought in his heart, Xiao Nizi is so active, maybe something will happen tonight, Li Tianfeng has a little such a premonition in his heart.

After the end of work, because today is Friday, the majority of employees happily began to get off work, and Li Tianfeng also tidied up the text on his desk a little.

"Brother Li, shall we leave now?"

Outside the door, Ouyang Feifei was walking in with a happy face, and had already changed out of her work clothes, with a beautiful face, Li Tianfeng thought in his heart, Fei Fei seemed to be getting more and more beautiful.

In fact, Ouyang Feifei is already beautiful, and recently, she has paid special attention to dressing herself, coupled with the nourishment of love, she is really getting more and more beautiful.
