Chapter 158 The cutting machine is not what you want to use, you can use it if you want

Roger snorted and didn't say anything. Gu Lie successfully passed the ore species test, which made him feel happy. He said before that excessive modesty is pride. Gu Lie's current performance is excessive pride and self-confidence. The designer naturally knows how much information is transmitted in the image. If such a data is changed to an ordinary person, I'm afraid it will take several days to barely write it down.

The old mechanic is indeed optimistic about Gu Lie's super memory, but people's brain power is always limited. Now that it is remembered, which is only a short-term memory. He will soon forget it. This is also the reason why Gu Lie passed the ore type test and has been urged to review it again.

The precision type II cutting machine is an ancient model, but its sharpness is not bad at all. If you operate it carelessly, it will indeed hurt you. This is what Roger is most worried about.

"Since you are so confident in yourself, let's start!" Roger ignored him and put the cutter's eyes on the bridge of his nose. The other hand held the robotic arm. There was a shiny thing at the front of the arm, which should be the cutting knife.

"See clearly, the operation is very simple, but you must be careful!"

Roger used his free left hand to firmly press on a metal plate about one meter long and about half a meter wide on the table. His right hand controlled the mechanical arm to slowly fall on it. The cutting knife moved slowly, and a very small gap suddenly appeared on the metal plate.

The cutting knife fell on the metal plate, which was as easy as cutting tofu. Gu Lie stared at it. Roger was too skilled in the cutting machine and soon cut a square piece of metal from the metal plate, even saving the process of drawing lines in the early stage.

"This is a caliper. Measure whether the four corners are 90 degrees, and you will know whether my square is cut accurately or not."

Gu Lie took the caliper and silently measured the angles of the four angles, all of which were 90 degrees, which was not bad at all. So far, he is really convinced of Roger. Such a unique skill can not be easily practiced. He must have experience in operating the cutting machine for a long time.

In the absence of comparison, horizontal and vertical straight lines are the most difficult to draw. Roger completely relied on experience to complete the cutting of square plates. This kind of craftsmanship really shocked Gu Lie.

"Awesome!" Gu Lie touched the four sides of the square metal plate. Normally, after the metal is cut, there should be some metal debris. It should not be so smooth, just like cutting and polishing. Two processes are completed in one go.

"Did you see the shiny cutting knife on the mechanical arm?" Roger pointed to it and said, "This is a Lanluo drill with nine-level hardness. It is harder than black crystal, and the output is rarer. It is generally used as a cutting knife."

These are actually in the previous operation instructions. Roger just repeated it again. I hope Gu Lie can remember these basic knowledge.

There are many kinds of mechanical knowledge, which may be the most complete knowledge system left on the mainland. If you want to be proficient in this, being talented is only one aspect, and more importantly, diligent and good at learning. This is what Roger wants Gu Lie to really do.

"You can try it!" Roger is ready to give up the place.

Gu Lie said, "Cut another piece. There was an operation step that I didn't see clearly just now."

Roger nodded and said, "I can demonstrate it a few more times. As long as you think you can get started, just tell me." He started the demonstration again.

Three square holes were quickly cut out on the rectangular metal plate. When Roger finished cutting the third piece, Gu Lie said, "I think I can try it."

Roger immediately gave up his position and told him, "You must be careful when operating, especially to avoid the unprotected left hand. Lanluo drill is very sharp. If you can't control it, I'm afraid you can't keep your left hand." He said that the advice was very serious. In his opinion, safety is much more important than the normal operation of the cutting machine.

Gu Lie nodded and said, "I'll be careful!"

He bent down and put his face up. His glasses were stuck on the bridge of his nose. His eyes were blurred, and then it became extremely clear in an instant. The glasses enlarged the plate in front of him dozens or even hundreds of times. It felt like the plate was close to his eyes.

Gu Lie straightened up slightly, looked at the metal plate with his real vision, and then looked at the enlarged vision through his glasses. The gap is really too big. No wonder Roger has been carefully telling him that if he can't adapt to the switching of vision, it is really easy to hurt himself because the action is too big.

Seeing that he carefully and repeatedly measured the gap between the real and the enlarged vision, Roger nodded with a little gratification. Gu Lie was very confident and cautious at the same time. At first, he was worried that he would become arrogant because he was too confident. Now it seems that it is completely unfounded to have such an idea.

"No wonder you can be the boss of a gang at a young age. It seems that old Fowler is really discerning and not worse than me at all." Roger smiled.

Gu Lie was absorbed. Naturally, he didn't know what Roger was thinking. After repeated comparisons, he could almost adapt to the difference between the two visions. Then he put it on the glasses again, and then carefully controlled the robotic arm and sent the cutting knife into the field of vision.

His movements fully meet the requirements of "light, soft and slow", sending the cutting knife into the enlarged field of vision like a snail.

When the cutting knife is not enlarged, it is only a small piece of crystal. After zooming in, you can see the very beautiful light blue multi-sided crystal and a very sharp edge. Even if it is placed dozens or hundreds of times, it still looks thin.

Gu Lie was very careful and gently dropped the cutting knife on the metal plate. Even if he was careful, he could not accurately grasp the force because of the first use. The cutting knife was inserted into the metal plate, which was really as easy as cutting tofu.

Gu Lie's cold sweat has come down. Only by operating it himself can he feel how sharp the cutting knife is. Taking a deep breath, he carefully dragged his robotic arm and drew a fine line in front of him, which looked straight.

It took Gu Lie more than ten minutes to cut off a square, while Roger only took him less than a minute. This gap hit him very hard, but he also knew that it was done by Roger after many years of hard work, and it was not something he could compare with now.

"Well, it's okay, but it still didn't work!" Roger threw the square metal plate aside, patted his hands gently and said, "Go on, you have to cut out a piece of metal plate similar to a square today to pass the exam." After saying that, Gu Lie, who left a wry smile on his face, turned around and left.
