The Wang family in the capital is a family of gate valves, a behemoth, and the marriage of the girls of the Wang family has no way to make their own decisions, nine times out of ten it is a political marriage, just like the marriage between himself and Wei Jin, which was a political marriage at the beginning, and the Wei family has a huge influence in the army.

Wang Juan thought in her heart, although she is a political marriage, she is lucky and happy, Wei Jin is very good, very considerate of herself, and the relationship between the two is even more very good.

Does your sister have such good luck? In case the future husband is a playboy, a gentleman, then ......

Wang Juan didn't dare to continue to think about it, and returned to Wang Ruobing and Li Tianfeng again, looking at the two, Wang Juan shook her head gently, even if Li Tianfeng is now running a relatively large enterprise, but it is almost impossible for the two of them.

Li Tianfeng and Wang Ruobing didn't seem to notice Wang Juan's expression, and after the two chatted happily, Li Tianfeng chatted with Wei Jin a few more words, and then said goodbye to everyone and put Jiajia in the car.

Not far away, the distance is only a few meters away, Liu Qingshan and others have already seen that the person in the military off-road vehicle should be Li Tianfeng's friend, seeing Wei Jin, Liu Qingshan felt a little familiar, but he couldn't remember.

Seeing that it was a young colonel, and the relationship with Li Tianfeng seemed to be very familiar, Liu Qingshan was slightly surprised in his heart, and thought in his heart, he didn't think that Li Tianfeng still had such a relationship.

Chen Dong, the representative of the army, saw that Wei Jin naturally knew, this was the commander of the Songzhou Military Division, and he heard that he had a very good relationship with his immediate boss Hu Lianggu, but now, Chen Dong suddenly realized, no wonder, no wonder, Li Tianfeng and Hu Lianggu had a good relationship, it turned out to be Wei Jin's sake.

Li Tianfeng watched Wei Jin's car leave slowly, and waved to Wang Ruobing in the car, after the car was far away, Li Tianfeng waved his hand, everyone got into the car, and the two cars, one in front of the other, drove towards Tianfeng Technology Company.

Next, the second finishing process of the flame tube is about to be carried out, for this process, Tang Jianyì has reservations, does not believe that Li Tianfeng can process the parts qualified, and Liu Qingshan is more looking forward to it, just like this, everyone will not hesitate to return to Tianfeng Technology Company, and will not stop to kill the No. 1 workshop.

Tianfeng Technology, No. 1 processing workshop.

Next to the German CNC lathe, Master Zhou is doing the preparatory work before processing, and the clamp has been placed next to the machine tool, and it can be installed on the machine tool after everyone has seen it.

Everyone walked to the side of the German CNC lathe, and the first thing to see was this CNC fixture, because the CNC fixture is installed with a flame cylinder to be processed, and the paraffin has been filled, at this time, the paraffin has been completely cooled and hardened.

Tang Jianyì squatted down, took out his reading glasses and put them on, and looked at them carefully, so when he saw it, Tang Jianyì exclaimed, "This, this, this maybe, how can there be no gap?" ”

No way!

It's impossible!

This, this is not scientific!

Thermal expansion and contraction, the volume of paraffin wax will shrink after cooling, and with the volume reduction after cooling, it will form a gap of two or three millimeters between the filled flame cylinder cavity, and this part, which is filled with paraffin, is not false, but there is no gap between the flame cylinder cavity, and the two are very tightly combined.

No way!

This was Tang Jianyì's first thought, with reading glasses, after looking carefully, after making sure that he was not mistaken, Tang Jianyì suspiciously used his fingernails to get a little paraffin down, and looked at it carefully, as if there was something strange about this paraffin.

Liu Qingshan and Cheng Gang naturally saw the difference, there was no gap between the paraffin wax and the flame tube, and the combination was very close, which was completely different from the paraffin paste used in their E factory.

Both of them nodded lightly, which can be seen that Tianfeng Technology Company has made careful preparations, and they have long taken into account the gap problem formed after the paraffin wax is cooled, and they have obviously taken what method to effectively prevent the appearance of this gap.

There is no gap, the combination between the two is very tight, these paraffin wax is filled between the inner cavity of the flame cylinder, the original hollow flame cylinder becomes solid, the rigidity is greatly enhanced, perhaps, this can really control the next processing deformation.

Tang Jianyì got a little paraffin wax with his fingernails, looked at it carefully, and even put it under his nose and sniffed it, Tang Jianyì seemed to have discovered a new continent, and said loudly: "This, this is not paraffin, this is definitely not paraffin." ”

Seeing this, Li Tianfeng smiled, and his eyes seemed to say, now you have just found out, of course this is not paraffin, no, it can also be said to be paraffin, it can also be said to be paraffin, it can also be said to be paraffin.

Liu Qingshan also used his fingernails to get a little down, looked at it carefully and asked, "Tianfeng, this looks like paraffin, but if you look closely, it is different from ordinary paraffin, what is this?" ”

Li Tianfeng smiled slightly, revealing the mystery, "Mr. Liu, this is a mixture of paraffin wax and a special low-melting point glue, we take into account that the shrinkage of paraffin wax is relatively large, so we will mix it in a certain proportion, and then add certain other ingredients to boil this special 'paraffin', even if this kind of thing is cooled and hardened, it will not have obvious shrinkage, and it will be closely combined with parts." ”

"Oh." Liu Qingshan suddenly realized, and then asked curiously, "Tianfeng, what kind of low-melting point glue is this, and what kind of ratio is it boiled into?" ”

Li Tianfeng smiled incomprehensibly, as if to say, Mr. Liu, this is a secret, it is inconvenient for me to disclose it.

Originally, Liu Qingshan planned to inquire about the detailed ratio and boiling method of this kind of thing, and in the future, if Factory E has similar thin-walled parts processing, it can be filled with this kind of thing, and the processing method similar to this one will be adopted.

However, seeing Li Tianfeng's eyes, Liu Qingshan knew that if he continued to ask, people would not tell him, this was a craft secret, and people naturally wanted to keep it secret.

Although there was a slight regret in his heart, Liu Qingshan's good mood was not affected, the inner cavity of this part was filled so well, there was not the slightest gap, Liu Qingshan seemed to see the hope of success, and thought in his heart, perhaps, Tianfeng Technology can give himself a huge surprise.

"Master Zhou, load the parts and fixtures on the machine and start processing." Li Tianfeng personally gave orders.

Hearing this, Master Zhou was not lazy at all, and immediately installed the parts and fixtures skillfully on this German CNC lathe, and then began to install a number of CNC tools, these tools, Master Zhou has checked them again, very good tools, all new knives.

Liu Qingshan also seemed to see that the quality of the knife was good, so he personally picked up a grooving knife and looked at it, and sighed: "Tianfeng, this knife is good." ”

Li Tianfeng said with a smile: "Mr. Liu, this is a non-standard tool specially designed for processing the outer circle of precision and narrow grooves outside the flame tube, thousands of yuan a piece, we have invested a lot of money, and this time the processing of the flame tube is a loss." ”

The real loss will naturally not, Liu Qingshan knew this, and said with a smile: "Tianfeng, I see that you are wealthy, just a few thousand yuan, it's nothing, it's drizzle." ”

"Haha......"

After speaking, the two looked at each other, laughed, the atmosphere is good, there is no trace of tension, the paraffin filling just now is very good, and this good quality special knife is specially designed, everyone seems to see the hope of success. Tang Jianyì also smiled slightly, as if he also recognized the CNC turning tool used for grooving.

After installing the knives, checking them, finding the right parts, and setting the knives, Master Zhou did it in an orderly manner, and Tang Jian looked at this qiē personally, nodding his head from time to time, obviously approving this qiē.

"Mr. Li, maybe my concept needs to change a little, maybe we can see success this time, maybe we can process qualified parts this time." Tang Jian yì said.

Hearing this, Li Tianfeng laughed, and sighed in his heart, Tang Jian is such a stubborn and such a person who admits reason, it is not easy to make such a concession!

As soon as you are ready, you are ready to start the official processing.

Master Zhou glanced at Li Tianfeng, obviously asking for instructions, Li Tianfeng nodded, and when he saw that he was allowed, Master Zhou immediately gently pressed the green machine tool start button, and the machine began to work and start processing......

Through the glass of the safety door of the machine tool, you can basically see the processing situation inside, only to see that under the spray of the coolant of the white flowers, the sharp turning tool lightly cuts off the iron filings, moisturizing things silently.

It takes more than an hour to process, however, at such a critical moment, we have no intention of leaving the processing site, we are patiently waiting next to the German CNC machine tool, and from time to time take a look at the processing situation in the machine tool.

The machine tool has been steady and very slight beep, the processing is normal, more than an hour later, the machine began to retract, the processing is about to be completed, everyone is full of interest, full of anticipation immediately stepped forward two steps, ready to witness this exciting moment.

The machine tool was completely withdrawn, and then stopped, which means that the processing of this process is all completed, whether it is good or bad, you can see the real chapter immediately, everyone's eyes are full of eagerness, look at the number of cars Master Zhou.

Master Zhou never thought that he would one day become such a focus, suddenly, his heart was slightly excited, straightened his chest, strode forward, and forcefully opened the safety door of the machine tool, and the processed parts were exposed in front of everyone.

Master Zhou took the air gun and carefully blew the parts to clean the coolant on them, and the parts looked very bright and seemed to be a little dazzling.

Everyone can't wait for Master Zhou's action to be faster, and immediately remove the parts quickly, and quickly measure whether the parts are processed or not.

"Hurry up, hurry up."

Chen Dong seemed to be the most uncontrollable, and hurriedly urged out, seeing this, Li Tianfeng couldn't help but smile happily.
