"God, it's beautifully processed!"

Little Brown picked up a part, looked at it carefully for a long time, and then shouted excitedly, even with a critical eye, Little Brown did not find any defects in this part, on the contrary, it was very perfect, very beautiful.

One, two, three......

Little Brown was excited and happy, and was full of interest, and personally inspected several parts in a row, and each part was so perfect and so beautiful, that it was not at all like a mechanical part, but like a beautiful handicraft.

"John, I wonder how the machining dimensions of these parts are?"

"Head, the size of this batch of parts is also perfect." Seeing Little Brown looking at him, John said excitedly: "Head, because this batch of parts not only has a certificate, but each part also has a record of the measured value of the size, you see." ”

After speaking, John took out a record sheet of measured values from the wooden box containing the parts, and the actual dimensions of each size were clearly recorded, very standardized, and stamped on it. ”

Little Brown took this measured value record sheet, and looked at it happily, so at a glance, Little Brown was happy again, if the measured value record number on this table is true, then the processing quality of this batch of parts is really first-class.

Seeing the bright red seal stamped on the measured value record sheet, Xiao Brown, who was coarse in Chinese, finally recognized "Tianfeng Technology Co., Ltd." after looking at it for a long time, which was not a part processed by the International Industry and Trade Branch of Factory E.

Xiao Brown, who is not a rookie, quickly understood the reason, and thought in his heart that it must be the International Industry and Trade Branch of Factory E that processed and found this factory OEM, but this company called "Tianfeng Technology" has an extraordinary strength.

Tianfeng Technology Co., Ltd.!

Little Brown read it silently, remembering this company firmly in his heart. Then he waved his hand excitedly, "John, arrange for someone to inspect a few parts immediately, I want to take a look at it myself." ”

Soon, a bearded inspector randomly selected a few pieces from this batch of parts, carefully measured them, and after such a measurement, the bearded man said with emotion: "Boss, these parts are all qualified, and the measured dimensions are almost the same as those recorded on this form." ”

The size is consistent!

"Awesome !!"

Little Brown waved his fist excitedly, because of excitement and excitement, and even his face flushed a little, which was completely different from the mood when he came out of Old Brown's office just now.

………

Tianfeng Technology Company.

The large monolithic blade disc processed for Factory B lasted for several days, and several finishing processes were carried out very smoothly, and at this time, the machining of the fine milling blade was being carried out.

Precision milling blades, is undoubtedly the whole processing process in the highest technical content, such a large integral blade disc, the use of a relatively new, more advanced blade design, processing technology content can be imagined.

A series of technical preparations took a lot of energy, and even the processing program was simulated several times on the programming software, and after each simulation, it was also improved and optimized, and finally, Li Tianfeng also personally checked.

For this processing sequence, Li Tianfeng attaches great importance to it, no, before the parts start processing, Li Tianfeng personally went to the processing site, stood next to this large precision five-axis CNC machining center, and watched the worker Master Qian make preparations before processing.

The parts have been installed on the workbench of the five-axis CNC machining center, and because several finishing operations have been completed, the parts already look like that, even the layman will know that this is a large monolithic blade disc.

The parts look more beautiful, and the fan blades we usually see are basically the same, the only difference is that the blades are still thicker, because the blades still have machining allowances, waiting for the finishing process to begin.

At present, the maximum thickness of the blade is 5.2 mm, and the machining allowance of 1.5 mm on one side is 1.5 mm, and after the processing of this fine milling blade, the blade will be completely formed, and it will be very beautiful, and the thickness will be reduced a lot, and the thickest place is only 2.2 mm.

The parts have been loaded on the machine tool table, the beautiful milling cutters that will be used in the precision milling blades are also ready, and the worker Master Qian is doing the final inspection, and then they will be installed in the tool magazine of the machining center one by one.

The tool magazine of this machining center is relatively large, which can be loaded with a lot of milling cutters, and after these milling cutters are installed in the tool magazine, the machine tool will automatically change the tool under the control of the processing program when the blades are finished.

Precision milling of blades, this will be a long process, day and night, almost three days and two nights, continuous processing for dozens of hours.

"Boss, it is estimated that the preparation work will be completed in more than ten minutes, and you can start the finishing milling of the blade, I am really looking forward to it!" Zeng Qinghai Road.

Zeng Qinghai also spent a lot of energy on the technical preparation of this process, and the technical content is so high, there is really a little expectation, if the processing is completed smoothly and the parts are qualified, it is also a good achievement.

High-precision milling of large fan integral blade disc blades, which can be proud and proud of the whole country.

Zhang Can also said: "Boss, if the precision milling blade of this part is completed smoothly, it will accumulate a lot of experience for the processing of similar parts in the future." ”

Li Tianfeng nodded, and out of the corner of his eye, he saw Wei Jiannan, who was holding the entire process manual, and was looking at it seriously, and did not speak, but he frowned from time to time while looking at it.

This whole process specification was brought down by Zhang Can and placed on the work table next to the machine tool. The whole process specification, a thick book, 16K size, all the processes of this integral blade, from the first process to the last process, there is a complete set.

In general, at the processing site, what process is processed, the workers will register and borrow the process card of which process from the on-site data room, and the process technicians generally use the entire process specification.

After reading this process specification, Wei Jiannan said: "Mr. Li, there seems to be a problem with this processing process!" ”

"Oh, I want to hear about it." Li Tianfeng asked with a smile.

Wei Jiannan said: "Mr. Li, you look at the processing process of the parts, you first mill the blade, wait for the blade to be completely formed, and then grind the tip of the blade, which is not appropriate and will cause problems." ”

Li Tianfeng smiled and said, "Wei Gong, how do you think it should be processed?" ”

Wei Jiannan said: "Mr. Li, after the completion of the blade milling, the blade will be finalized, and then you will grind the outer diameter of the blade tip, you know, the size of the outer diameter of the blade tip is very important, not only only the tolerance of 5 wires, but also the tip of the blade beats very strictly, and then grinding the blade tip after the precision milling blade is not appropriate, I am afraid that there will be problems." ”

Seeing Li Tianfeng looking at himself with a smile and motioning for himself to continue, Wei Jiannan continued: "Because the blade has been finished milling, the blade is very thin, and the blade tip grinding belongs to intermittent grinding. ”

Li Tianfeng said with a smile: "Wei Gong, you know one, you don't know the other, I said that if the outer diameter of the blade tip is processed to the final design size before the precision milling of the blade, and then the blade is finished milling, the blade will become longer after the finish milling, and the outer diameter of the blade tip that has been processed to the final design size will be out of tolerance, do you believe it or not?" ”

How can it be!

The leaves will also get longer! Who to fool!

Of course Wei Jiannan didn't believe it, this was simply unheard of, "Mr. Li, you're kidding, this, I don't believe it, and it's impossible." ”

"Wei Gong, whether you believe it or not, anyway, I believe it, we will process according to the current processing technology, first precision milling blades, and then grinding the outer diameter of the blade tip, the process will not change!"

Anyway, I believe it!

Zeng Qinghai and Zhang Can glanced at each other, and both of them laughed softly, they didn't think that their boss was so humorous at this time.

Hearing this, Wei Jiannan blushed, and said loudly: "If you don't change the processing process, then wait for the parts to be scrapped, I can't stay in your Tianfeng Technology, I'll go back to Factory B." ”

After speaking, Wei Jiannan left angrily.

That's it!

Zeng Qinghai and Zhang Can glanced at each other again, and Zhang Can whispered: "Boss, he's leaving?" ”

Li Tianfeng said disapprerovingly: "Let's go, let's process ours, and start the processing of the fine milling blade when we are ready." ”

The preparation before processing was very smooth, and after it was ready, the worker Master Qian asked: "Mr. Li, start processing?" ”

Li Tianfeng waved his hand: "Start processing!" ”

Press the green start button, the machine tool starts to work, and begins to carry out the precision milling of the blade, such a five-axis linkage processing, which looks pleasing to the eye and is very ornamental!

After everyone watched it with great interest for one or twenty minutes, Li Tianfeng was about to leave, and his mobile phone rang, and when he saw that the caller ID was "Yang Xianfeng", Li Tianfeng smiled slightly, I don't know what Yang Xianfeng is looking for himself, do you invite yourself to dinner again.

Last time, Yang Xianfeng basically invited himself to eat in the lotus hall of the state-guest hotel when he got off work, Li Tianfeng thought in his heart, now it's almost time to get off work, won't he really invite himself to eat again.

As soon as the phone was called, Yang Xianfeng's hearty voice came, "Tianfeng, how about two drinks after work?" Or the old place, the Lotus Hall of the State Guest Hotel. ”

Really invite yourself to dinner, Li Tianfeng was surprised for a while, and thought in his heart, what is the matter with inviting himself to dinner this time?

"Mr. Yang, you're welcome, then see you in the Lotus Hall."

Li Tianfeng was very refreshing, and immediately agreed, the last time he invited himself to dinner, he gained a lot, and took a processing business of more than 10 million US dollars, is there a good thing this time?
