Long Yingshi came really fast, less than nine o'clock in the morning, he took the business car of Tianfeng Technology, from the hotel to Tianfeng Technology.

Coming with Long Yingshi was a middle-aged man with glasses, his hair was a little gray, and he looked over 50 years old, but Wei Jiannan did not appear. Seeing Long Yingshi get out of the car, Li Tianfeng took two steps forward and said enthusiastically: "Mr. Long, welcome to Tianfeng Technology again!" ”

This is Long Yingshi's second time to Tianfeng Technology, and he is also an acquaintance with Li Tianfeng, Long Yingshi said with a smile: "I remember that the last time was not very long, and Tianfeng Technology has changed a lot." ”

Tianfeng technology is vigorously building, recruiting a lot of employees every month, purchasing a lot of machine tools and equipment every month, the changes are naturally relatively large, take the huge technology center building as an example, the last time Long Yingshi came to this building has not been capped, now, has basically completed the exterior wall decoration, it looks like that thing.

"Mr. Li, let me introduce to you, this is Comrade Liu Yong, deputy chief designer of our Second Aero Engine Design Institute."

Liu Yong took two steps forward and shook hands with Li Tianfeng warmly, and Li Tianfeng said enthusiastically: "Mr. Liu, welcome." ”

Li Tianfeng estimated that Liu Yong should be the designer of the integral blade disc, and this time he came here to take a look at the processing of this part.

"Mr. Long, let's go up and sit down first, have a cup of tea, and then go to the processing site to take a look at the parts (), how about it?" Li Tianfeng said.

Surprisingly, Long Yingshi hurriedly said: "Mr. Li, no, let's take a look at the processing of parts first." ”

Li Tianfeng was slightly surprised, he didn't think that Long Yingshi only had this part in his heart, and he attached so much importance to it, even Liu Yong next to him nodded hurriedly. "Mr. Li, you're welcome, let's take a look at the parts first."

Attaching so much importance to this part, this part must not be simple, Li Tianfeng thought so in his heart, and did not insist. Said with a smile: "Then we will enter the processing site, the processing of this part is basically nearing the end, and at present, we are preparing to refine the outer diameter of the blade tip." ”

"Finished milling the blades?" Long Yingshi was overjoyed in his heart, and his steps couldn't help but be a lot faster, "Mr. Li, the processing is relatively smooth." ”

Li Tianfeng smiled and sold a pass, "Mr. Long, wait a minute, you can take a look for yourself." Let's go, I'll take you there. ”

This integral blade disc part, which Long Yingshi is very concerned about, is placed next to a large vertical CNC grinding and milling center, which is an imported large equipment, even if the processing of this 915 mm diameter integral blade disc is not a problem.

The so-called grinding and milling center, as the name suggests, this machine can grind. It can also be drilled and milled, and the grinding head can be installed on the machine tool for grinding processing. Such as grinding the outer circle, grinding the inner hole, etc., it can also install drills, milling cutters and other alloy tools for drilling and milling. Milling surfaces, etc., are very versatile.

This brand-new large-scale vertical CNC grinding and milling center was installed and debugged in less than a few days, and only a batch of parts were processed, this time. The outer diameter of the finely ground blade tip belongs to the first formal processing of parts.

Seeing such equipment, Long Yingshi exclaimed: "Mr. Li, good guy, you also have such advanced and high-end equipment?" ”

Li Tianfeng smiled proudly, "I just bought it from abroad, nearly 20 million, and the outer diameter of the finely ground blade tip is processed on this machine tool."

Long Yingshi nodded, saw the overall blade disc next to the machine tool, and couldn't help but speed up his pace and walked over quickly, Liu Yong was the same, he also sped up his pace, and walked over quickly with a happy face.

Long Yingshi, Liu Yong and the two, with great interest, looked at this part carefully and with great interest, because the parts basically completed all the finishing processes, basically only the fine grinding of the leaf tips remained, and the parts looked basically the same as the parts on the design drawings.

It's just that this is the real part in front of you, more intuitive, more visually impactful, and the parts are perfectly processed, it looks very beautiful, Long Yingshi and Liu Yong are both experienced and very visionary characters, as soon as they saw this part, the two looked at each other, and they saw the excitement and joy in each other's eyes.

"Mr. Li, I didn't expect it, I didn't think about it, the processing of parts is so beautiful, amazing, very amazing!"

Liu Yong also said: "Mr. Li, I can't imagine that you can process the parts so well, you look at the surface of this blade, how smooth it is, tsk, the blade shape is completely machined, there is no trace of artificial polishing, this is the first time I have seen it, amazing!" ”

Liu Yong happily gave Li Tianfeng a thumbs up, the praise on his face was unobstructed, and Liu Yong did not hesitate to praise Li Tianfeng with his words.

Liu Yong is happy!

I didn't think that the parts were processed so well, especially the surface of the blade, and there were no traces of artificial grinding like the blade disc I saw before, this piece of beautiful blade was completely milled out of high-speed milling with a milling cutter, very smooth, and when you look carefully, you can vaguely see the milling processing traces of the milling cutter.

It's so beautiful!

It's perfect!

I can't believe it!

Liu Yong knows the importance of this part clearly, and now, the processing quality of this part is so high-quality, Liu Yong is very happy, just like drinking cold sour plum soup on a June day, it is refreshing.

Long Yingshi is also very happy, this part is related to a heavy scientific research project, at the beginning, put this part into Tianfeng Technology processing, Long Yingshi also withstood a lot of pressure, now, the quality of parts processing is so good, Long Yingshi felt a burst of relaxation, a burst of joy rose from the bottom of his heart, straight through the Tianling cover.

"Mr. Li, I want to thank you very much, I have a treat at noon today, let's have a drink."

Li Tianfeng was also very happy, and said with a smile: "Mr. Long, then you broke the bank." ”

"It's okay, I'm so happy today!"

Long Yingshi was indeed very happy, and with great interest picked up a size measurement record table next to the parts, one size, one size looked, and saw that the sizes were all qualified, and there were some important sizes that were in the middle.

Suddenly, Long Yingshi was full of joy again, "Mr. Li, the quality of parts processing is so good, we must drink two cups at noon today." ”

Li Tianfeng took advantage of Long Yingshi and said happily: "Mr. Long, you must have a few drinks at noon, but I know that you have a lot of parts in your hands to find a machining company for OEM, consider our Tianfeng Technology, we will not let you down." ”

"No problem, let's talk about these things in detail in the afternoon." didn't think about it, Long Yingshi agreed so happily, Li Tianfeng was overjoyed.

Everyone was happy and the atmosphere was good. This part was finished yesterday afternoon with the finishing milling blade, and since yesterday afternoon, it has been preparing for the machining before the outer diameter of the blade tip, and these preparations are basically carried out.

The worker in charge of this process took a lot of strong strings, carefully and tightly wound and tightened on this piece of large blades, seeing this scene, Long Ying looked at Li Tianfeng puzzled, and his eyes seemed to say, what are you going to do?

Li Tianfeng smiled slightly and explained: "Mr. Long, this is a process method, because the requirements for fine grinding of the outer diameter of the blade tip are too high, and the blades are full of elasticity, and they are still intermittently grinding, we have to use this method to fix these blades, and then, there are things to fill between each blade." ”

And stuffing stuff!

Li Tianfeng nodded, "Filling things between the blades is also a very effective way to enhance rigidity, prevent the blades from springing and fluttering during the processing process, and improve the processing performance." ”

"Oh, there's another way." Long Ying was interested and ready to take a look.

Li Tianfeng waved his hand, and saw that Zhang Can immediately arranged two workers to bring the mixture of paraffin wax and glue that should be boiled into a liquid state with two large iron buckets, and then used a simple mold that had been prepared long ago to put it on the outside of the leaves, and then began to pour these things between the leaves.

In the end, it was the chief engineer of Factory B, and he quickly understood the principle, and Long Yingshi's eyes lit up and he looked at it with great interest.

Liu Yong obviously saw such a processing method for the first time, and he was also very interested, watching the workers busy.

Two large barrels of things were poured down, and soon, the leaves were filled with a mixture of paraffin wax and glue, and these things gradually cooled and solidified, and these things were closely combined with the blades, and the simple mold was removed, and the whole plate of leaves became a whole.

Wonderful, really wonderful!

Long Yingshi couldn't help but admire again, and at the same time, he kept this new process method in mind and prepared to test and promote it in Factory B.

"Mr. Long, it will take a certain amount of time to completely solidify, and the processing will not start until the afternoon, now I will take you to a place to relax."

"Yes." Long Ying agreed.

So, a group of people took the car out of Tianfeng technology, to the Songzhou Reservoir area, now, it is already the season of spring flowers, the scenery is very good, a warm breeze blowing, very comfortable, eat early, everyone in the reservoir fishing for an hour or two.

At noon, Long Yingshi insisted on having a treat, Li Tianfeng nodded in agreement, everyone talked and laughed, and ate a meal for one or two hours. After eating, Long Yingshi asked to hurry up and return to Tianfeng Technology Company, obviously, Long Yingshi was very concerned about the fine grinding of the outer diameter of the blade tip.

Li Tianfeng began to smile, waved his hand, everyone took the car back to Tianfeng Technology Company, sat in the reception room first, chatted, took a break, and drank tea by the way.
