"Brother Li, help me take a look at this process, whether it is feasible to improve it in this way."

As soon as he entered the office, Li Dawu came to ask Li Tianfeng, these days, Li Tianfeng arranged some tasks for everyone, all of which are relatively simple processes, such as Li Dawu's process, which is a rough processing process, and the purpose of improvement is to improve processing efficiency.

Before Li Dawu's improvement, Li Tianfeng gave guidance and talked about his own processing ideas, and Li Dawu basically improved according to Li Tianfeng's intentions.

After a little look, seeing that there was not much difference, and basically improving according to his own ideas, Li Tianfeng said: "There are a few small problems here, the feed amount of the first rough turning is slightly smaller, the speed is increased by 50%, and the second rough turning is increasing the amount of near the knife, and the fine turning is canceled." ”

Because this process is rough machining, even after the processing is completed, there is still a millimeter of machining allowance, Li Tianfeng decisively canceled the finishing turning.

"Brother Li, in this way, the processing efficiency has been improved a lot, I asked the previous processing of this process of the worker, this process does not process a part at least two or three hours of time, we estimate that this improvement can be completed within an hour.

Li Tianfeng nodded, it is certain that the processing can be completed in an hour, the special feature of this process is that the machining allowance is large, and the accuracy requirements are not high, because it is a rough machining process, the only difficulty is that the part material is a high-temperature alloy, which is easy to wear out the tool, which is difficult for Li Dawu.

However, with the guidance of Li Tianfeng, this is not a problem, this process was quickly improved, with the processing program issued, the processing of this process of the worker master was surprised to find that the processing efficiency increased more than three times, a look at the new program list on the name of the colonel is Li Tianfeng, the worker master said in his heart, sure enough, it turned out to be Li Gong, no wonder the efficiency has increased so much.

Of course, this is a few days later.

After Li Tianfeng instructed Li Dawu, he instructed Zhang Can and He Baitao, and then assigned new tasks to the three of them.

Each of the three of them basically improves a process every day, and the improvement of these processes is not difficult, and Li Tianfeng, who is a hard bone with great difficulty, naturally did not arrange for the three of them to do.

After telling the three of them, Li Tianfeng went to the tooling and mold manufacturing branch of Factory E, where several broaches that Li Tianfeng needed were being manufactured, and these broaches were naturally prepared to be used to process the tenon and groove of the first-stage turbine disc of the turboshaft C engine.

The broach manufacturing may be completed until tomorrow or the day after tomorrow, today, Li Tianfeng is relatively free, so Li Tianfeng went out of the E factory and went to the remote factory he rented.

The curtains on the windows of the factory were tightly drawn, and it was quiet around the factory, and there were hardly any people, at most one or two villagers could be seen.

After entering the factory, the factory door was carefully closed, and suddenly, the factory was dark, and it can be seen that the shading effect of the curtains is good, and after the lights are turned on, the factory building is suddenly bright.

On the test table, the dark blue solution was very eye-catching, and naturally it was also very beautiful, Li Tianfeng's heart was slightly excited, and he thought in his heart, success or failure in this move.

To calm down the excitement in his heart a little, Li Tianfeng began to configure two reagents, one is a catalyst, and the other is a setting agent and a coagulant.

These two reagents are very complicated, and they are also very critical, that is, the configuration of the catalyst took Li Tianfeng more than an hour, looking at the golden liquid of about twenty or thirty milliliters in the test tube, Li Tianfeng often breathed a sigh of relief.

At the same time, Li Tianfeng thought in his heart that he had made a cameo appearance as a chemist this time.

Carefully poured five milliliters of golden yellow catalyst, and then carefully dripped into the blue liquid on the test table, while carefully dripping the catalyst, while carefully stirring with a glass rod, in an orderly manner.

After making this qiē, Li Tianfeng prepared another 100 ml of setting agent, and then carefully poured this 100 ml setting agent into the glass container of blue solution on the test table, and gently stirred it while pouring it.

After stirring evenly, Li Tianfeng stopped stirring, and then quietly looked at these blue liquids, time passed minute by minute, and the whole plant was very quiet, only Li Tianfeng's rapid breathing.

Li Tianfeng's breathing was so rapid, which showed that his heart was not calm at all, and he would soon witness a miracle in one fell swoop.

As time passed, at the bottom of the glass container, transparent crystals began to appear, like grains of glass, but this is not glass, this is a man-made diamond.

In that time and space, in that Li Tianfeng's memory, man-made diamonds almost completely replaced natural diamonds, and the invention of man-made diamonds was a genius chemist who used chemical methods to create perfect man-made diamonds at a low cost.

Man-made diamonds have existed for a long time, but basically they use physical methods and terrifying pressure to make carbon atoms into diamonds, that is, diamonds.

This method is difficult and costly, and gem-quality diamonds are rare, so they are not popular, and natural diamonds are widely used in the jewelry industry.

Seeing the diamonds condensed one by one, the excitement in Li Tianfeng's heart was irrepressible, and he shouted frantically in his heart, I succeeded, I succeeded.

pinched himself hard, and Li Tianfeng, who grinned in pain, laughed happily, he was not dreaming, he really succeeded, and he used chemical methods to get artificial diamonds.

Artificial diamonds are no different from natural diamonds, which even the most sophisticated instruments and the most experienced appraisers cannot identify, because these artificial diamonds are also made of carbon atoms, and their physical structure is exactly the same as that of natural diamonds.

The dark blue liquid becomes very pale in color, almost colorless and transparent, and at the bottom of the liquid, a layer of rough diamonds of various sizes is very attractive.

Li Tianfeng immediately filtered out these diamonds, and then rinsed them clean, as for those unwanted solutions, they were flushed into the sewer, the amount of solution was very small, and it would not pollute any environment.

The diamonds are clean, very gratifying, with different shapes, but high transparency, pure without a trace of impurities, and the clarity is certainly first-class, even top-notch.

The number of diamonds is hundreds, the only pity is that these diamonds are of different sizes, the small ones may only be a few tenths of a carat, most of them are estimated to be one or two carats, and the larger ones are only a few carats, and the diamonds that exceed five carats should be very few, or even none, and Li Tianfeng does not have an electronic scale for weighing, which can only be estimated.

However, even so, even if these diamonds are not very big, but it is already a big surprise, these hundreds of pure and transparent diamond rough diamonds are definitely a huge wealth, this is the first time to make zuò man-made diamonds, and a lot can be made later.

Perhaps, it is possible to monopolize the diamond market of the entire world in the future, but before absolute strength, Li Tianfeng will definitely not do this.

Building your own aviation empire requires a lot of money, and perhaps the main source of these funds is the sale of man-made diamonds.

Happily and excitedly looked at it for a long time, as if these diamonds never got tired of looking at them, until he was a little hungry, Li Tianfeng looked at his watch, it was already noon, Li Tianfeng couldn't help but smile happily.

Packing these diamonds in a small plastic bag, putting this bag of diamonds into his pocket, and patting his pocket again, Li Tianfeng suddenly felt a sense of satisfaction.

After cleaning up the inside of the factory and locking the factory door, Li Tianfeng left the factory door with confidence. Li Tianfeng was not worried that his secret would be leaked out, on the one hand, no one would have thought that he could use chemical methods to make diamonds, on the other hand, even if he knew, he didn't know the specific process, the ratio and formula of those solutions were all in Li Tianfeng's mind, as long as Li Tianfeng didn't say it, no one would know.

"Sister Juan, where are you?"

"Tianfeng, I happen to be in the store in the provincial capital CS City, do you have a rough diamond?" Wang Juan immediately guessed what Li Tianfeng meant.

"Sister Juan, you are really like a god, I came to you with these rough diamonds, how about it?" Li Tianfeng said.

Wang Juan thought for a while and said, "I'll send a car to pick you up, it's safer." ”

The provincial capital CS City is about forty or fifty kilometers away from Songzhou, which is convenient without an hour's drive. Li Tianfeng considered that it was not a matter for him to run around with a bag of valuable diamonds, so he said: "Okay, I'll wait in Factory E." ”

After talking to Wang Juan on the phone, Li Tianfeng made another call to Chen Xiangchun to ask for a half-day leave, but Chen Xiangchun didn't ask anything, and readily approved Li Tianfeng's half-day leave.

After making this call, Li Tianfeng was a little looking forward to how much his batch of diamonds could be sold for, thinking of this, he pinched the bag of diamonds in his pocket through his clothes.

At noon, at the door of the collective dormitory, I found a restaurant at random, ordered a few dishes and ate them, there are many restaurants around the entrance of the collective dormitory, mainly the young people who live in the collective dormitory eat here, the business is good, and many restaurants taste good.

Two meats, one vegetable and one soup, one person is indeed a bit extravagant, but thinking that he will earn his first pot of gold soon, Li Tianfeng doesn't mind the meal money of one hundred and ten yuan.

Slowly and leisurely ate a good Chinese food, about one o'clock at noon, Li Tianfeng's mobile phone rang, and when he saw that it was an unfamiliar number, Li Tianfeng estimated that it should be the person sent by Wang Juan to pick him up.

Sure enough, as soon as the phone rang, a young man's voice came from inside, "Are you your husband?" I was sent by Mr. Wang to pick you up. ”

Li Tianfeng said a location, then hung up the phone and walked quickly towards this place. The place where the two of them agreed is very close to here, right next to South Avenue.

A black off-road vehicle drove over slowly, and Li Tianfeng knew that he was coming to pick him up as soon as he saw the license plate number, so Li Tianfeng waved at the off-road vehicle.
