A few days later, the Beijing International Science and Technology Exhibition officially began. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo

At the same time, the press conference of the Chrono Group also began. Moreover, what will be displayed is not a technology, but three technologies at the same time, how many years do others have to wait for a technology, and the three scientific and technological breakthroughs of the Chrono Group at once, this gimmick alone has attracted the attention of many people. In addition, the popularity of Su Jing and artificial intelligence is still there, and it is even more eye-catching.

"Why doesn't the Chrono Group participate in the Beijing International Science and Technology Exhibition? Even if you prefer to hold your own press conference, then you don't need to choose this time, so won't the limelight be stolen by the science and technology exhibition? ”

"I heard that there are many relationships between the Huo family and the Fu family in the Beijing International Science and Technology Exhibition, and Huo Yunshu and Fu Hongxue joined forces to suppress it, so that Su Jing could not participate in the science and technology exhibition. ”

"It turns out that there is such a thing, so Su Jing deliberately chose this day, is this to be positive?"

"How dare I go and go head-to-head with an international science and technology exhibition?"

"I don't think it's courage, it's not knowing whether to live or die. In which year did the international science and technology exhibition not attract many new high-tech and eye-catching, where can a group compare?"

"Didn't Su Jing come to the press conference, I think he knew that he was going to lose face this time. ”

Under the watchful eye, the press conference of the Chaokong Group began, Su Jing didn't come in person for some reason, but Zheng Nan and Wang Zhuo were there, and many viewers and reporters also started a live broadcast. The audience in the live broadcast room quickly broke 500,000, most of them in the face of Su Jing and artificial intelligence.

The first scientific and technological achievement displayed by the Chrono Group is the laser cutting machine, hearing this name, many viewers were stunned, subconsciously a little disappointed, laser cutting machine or something, isn't it already there, this is not new.

"Laser cutting machine?" The five families of Zhongyun City are also paying attention to the press conference of Chaokong Group at the moment, they have more or less some grievances with Su Jing, and Su Jing started in Zhongyun City, so they can't help but pay attention. Among them, Song Junyi, the eldest and youngest of the Song family, couldn't help but be stunned when he heard the laser cutting machine.

"We are about to invest in this aspect, why is it so coincidental?" Song Gaoyun, the head of the Song family, was stunned.

"It can't be said to be a coincidence, Su Jing now has to intervene in all walks of life, and it will be difficult not to encounter it in the future. However, the laser cutting machine industry is relatively mature and is developing slowly, which is a business opportunity for us, but for him, this profit is not eye-catching, right?" Song Junyi was a little puzzled.

Compared with the traditional oxyacetylene, plasma and other cutting processes, laser cutting has fast cutting speed, narrow cutting slot, small heat-affected zone, good verticality of cutting seam edge and smooth cutting edge. At the same time, there are many types of materials that can be laser cut, including carbon steel, stainless steel, alloy steel, wood, plastic, rubber, cloth, quartz, ceramics, glass, composite materials, etc.

With the rapid development of the market economy and the rapid development of science and technology, laser cutting technology has been widely used in automobiles, machinery, electricity, hardware and electrical appliances and other fields.

In recent years, laser cutting technology is developing at an unprecedented rate, with an annual growth rate of 15%~20%. Since 1985, China has grown at an annual rate of nearly 25%.

At present, there is still a big gap between the overall level of China's laser cutting technology and advanced countries, so laser cutting technology has broad development prospects and huge application space in the domestic market.

However, the outlook is relative. Compared with artificial intelligence, laser cutting machines are weak.

What's more, the laser cutting machine has been there for a long time, is developing slowly, and does not belong to any emerging industry.

"Is it actually a laser cutting machine?" Among the other people who watched the live broadcast, there were also some people in the laser cutting machine industry, who were also stunned when they heard the news, and they all subconsciously felt a trace of disappointment, which is not new.

However, when the Chaokong Group began to demonstrate the laser cutting technology, a piece of steel, wood, ceramics, and glass were cut out by the laser cutting machine according to a specific shape, which was fast and accurate, clean and neat, and it was as pleasant as cutting tofu.

"Oh my God, it's too fast. ”

"Isn't laser cutting so fast?"

"Laser cutting is very fast, but not so fast, the cutting speed of ordinary cutting machine is 0-15000mm/min, but it can reach 75000mm/min. ”

"The idle speed of an ordinary cutting machine is 0-20000mm/min, and it can reach 100000mm/min. ”

"Also, the repeated positioning accuracy is too high, the repeated positioning accuracy of ordinary laser cutting machine: ±0.03/300mm, its accuracy is more than five times higher. ”

"The focus spot is also frighteningly small, so the cutting gap is not visible, and the cut quality is extremely high. ”

"Oh my God, this is a cutting artifact. ”

"How the hell is this done?"

"Isn't this laser cutting technology better than abroad?"

"It's not just better than abroad, I don't know how many times better. ”

Song Junyi and other people in the industry are about to go crazy with excitement, and those people who don't know how to eat melons, looking at the description of industry insiders, probably understand what is going on, and can't help but be speechless.

"Oops, the batch we ordered, I'm afraid it's going to be scrapped. Song Gaoyun's face was not very good-looking.

"Also, I didn't order much, we didn't get the goods, we only gave a deposit, we don't want those goods, forget if you can't get the deposit back, buy the goods of the Chrono Group." Song Junyi said.

"That's all there is to it. Song Gaoyun nodded and said, as soon as the laser cutting technology of the Chaokong Group comes out, can other laser cutting technologies still live?

"The press conference of the Chrono Group began. At the Beijing International Science and Technology Exhibition, Huo Yunshu and Fu Hongxue were wandering around to watch the science and technology exhibition, and a polite young man wearing glasses came over and said.

"There should be a live broadcast, let's go see the live broadcast, I heard that what they want to show is not one technology, but three technologies. Huo Yunshu said.

"In terms of engines alone, I don't believe that he can achieve anything, how long has it been since he poached my talents, what can he produce? What three technologies may be just a gimmick for indiscriminate filling. Fu Hongxue said.

A few young people echoed him:

"It's useless to engage in this kind of gimmick, everyone will definitely pay attention to the science and technology exhibition when you look back, who will pay attention to his small press conference?"

"If he holds a press conference for a while, it will be forgotten, but he actually chooses this time, which Beijing International Science and Technology Exhibition is not a gathering of various emerging technologies, which is comparable to him, isn't this looking for death, I don't know how thick the sky is. ”

They turned on the live broadcast and found that the number of viewers had reached almost one million, and it was still growing rapidly, they couldn't help but be slightly stunned, and then looked at the audience's excited reactions, they couldn't help but be even more strange, it turned out that the first scientific and technological achievement was laser cutting technology, what is so surprising about this?
