Hoffman personally poured a cup of tea for Liu Lang and Sun Hu, and said as he poured it.

"Jimmy, this is the tea I bought from Frankfurt Chinatown, it is the best tea, the other party told me that this kind of tea only produces two kilograms a year, and in ancient times it was the tea that your Chinese emperors drunk, come, taste it!"

Liu Lang almost laughed out loud when he heard it, and the tea that the ancient emperor drank, where can you see this kind of tea in Germany? Obviously, this guy was deceived, but Liu Lang didn't point it out, after all, it was a bad thing.

Liu Lang picked up the teacup and took a sip, very ordinary tea, only two yuan a pound in China, a mid-range product.

"How's this tea?"

Obviously, this was specially bought by Hoffman for Liu Lang, of course he wanted to know Liu Lang's feelings.

"Well, good tea, I can't drink this kind of good tea in the United States, thank you!"

Liu Lang's answer made the other party very happy, of course he couldn't sweep away the other party's interest.

"Hoffman, let's go to your workshop first!"

Liu Lang didn't want to waste time.

"No problem, let's go!"

Hoffman took the two of them down the office building, and then walked into a factory, put on protective equipment at the door, and everyone who entered the workshop had to wear blue overalls, hard hats and protective glasses, hats and protective glasses Liu Lang was fine, and his head had to wear the largest hat, but he was very short, and there was no suitable clothes for him, so he could only find the smallest one to wear, as if he had a robe on his body.

Dressed in protective clothing, Hoffman pushed open a door, and immediately a hot wind blew in, apparently blowing the dust off the three of them.

The three of them walked through a short corridor, and when they turned the corner, their eyes suddenly opened up.

There are more than a dozen electronically controlled machine tools in the spacious and bright workshop, and a worker is carefully operating in front of each machine.

"Jimmy, our company produces many types of knives, white steel knives, tungsten steel knives, alloy knives, and purple knives, especially purple knives are the best, which can be used for high-speed cutting and are not easy to wear, and now these workers are making different kinds of purple knives. ”

Hoffman attaches great importance to Liu Lang, and as soon as he came up, he showed the other party the most technical tools, of course, he showed Liu Lang to show sincerity, he didn't know that Liu Lang himself was a mechanical expert, and his level was higher than his in many aspects, if he knew Liu Lang's true identity, Hoffman might not be so casual.

"Oh, your factory is much better than my friend's, his factory is full of noise, the machines run so deafening that they can deaf people's ears, and the factory is so dirty, there are oil stains everywhere, there is nowhere to stay, I don't want to go a second time when I go once. ”

Liu Lang pretended to be surprised.

"Jimmy, your China's mechanical level is not enough, the mechanical equipment is mostly mechanical connecting rod mode, of course there is a huge noise in operation, and my equipment here is an electric drive bearing, in our country is a relatively high level, of course, your country is now developing very fast, maybe in four or five years this equipment will also be popular. ”

"Well, huh, these knives seem to be different, huh?"

Liu Lang began to "pretend to be crazy and stupid".

"Of course it's different, this is a flat-bottomed knife, used for flat and straight sides, clear plane angles, this is a ball knife, used for various curved surfaces, light knives, this is a bullnose knife, used for steel roughing, and rough leather knives.

These are divided according to the cutter head, and there are also according to the shank: straight rod knife, which is an oblique rod cutter.

These are divided according to the blade, two-edged, three-edged, four-edged, the more blades, the better the effect, but the more work done, the speed and feed are adjusted accordingly, and the number of blades is long and long.

In addition, there are ball knives and flying knives, the advantage of flying knives is that they can clear the bottom corner, the force is large and the light is bright, and it is more used for contour shape, sometimes the flying knives do not need to be in the light, and the disadvantage is that the concave size and plane ruler are less than ......... when the diameter of the flying knives is smaller. ”

Hoffmann is a "technical master" who talks a lot about all kinds of knives.

"Well, well, these knives are so beautiful, why can you make such beautiful knives and my friend can't?

Of course, Liu Lang knows these knives, but they are just ordinary common-sense questions, and what Liu Lang wants to know is some unique processes of the other party in making knives.

Hoffman didn't know that Liu Lang was an expert, and he never thought that Liu Lang's attainments in machinery had reached the pinnacle, he was the chairman of Shengtang Company, a billionaire, and such a rich person would engage in machinery? This is not logical, in addition, Hoffman saw that Sun Hu was not a peer, although the engineers were a little upright, but there was no one like Sun Hu who followed Liu Lang closely, and the fool could see that he was Liu Lang's bodyguard.

A child and his bodyguard, the two of them are laymen, even if they put the most core technology in front of them, it is useless, because you can't understand it.

This is Hoffman's idea, so he doesn't have any concerns about Liu Lang.

Liu Lang is also playing an "ignorant" person at this time, who can't ask some professional questions, and can only knock on the side, unintentionally letting the other party "confess himself", which is a psychological suggestion and uses Hoffman's obsession with technology.

Sure enough, Liu Lang's question ignited the other party's interest, and then he took the two of them to the next workshop, the mold workshop.

"This is our mold manufacturing workshop, mold design is the core technology of our factory, this workshop is usually not open to the public, but Jimmy you can. ”

Hoffman secretly glanced at Sun Hu as he spoke, and found that the other party's attention was not on those devices at all, and he once again confirmed that his guess was correct, and the other party was a layman at all, so he continued.

"At present, most mold factories realize that high-speed machining requires more than just short processing time, and sometimes long-term machining parts are better than short-term machining parts. ”

Liu Lang listened and pretended to think for a while.

"That friend of mine once said that the machine tools in your developed countries are fully automatic, the efficiency is very high, and the time it takes to process ten parts is shorter than the time it takes to process one part in our country, it seems that he is wrong. ”

Hoffman waved his hand.

"No, no, it mainly depends on the process, other companies may be faster than us, but the process is not always faster, but it has to be perfectly combined......... Well, Jimmy, have you seen the race cars?"

"Of course, I once watched an F1 race with a friend in the United States!"

"Wow, F1, that's exciting, but it's nowhere near as good as Adès' concert............ Well, far from it, our craft is similar to the driving of a race car. ”

At the mention of Adeth Hoffman, a smile broke down.
