Chapter 2027

In the first few minutes, the experts had no idea. Even if there was no coolant, the tool could support at the beginning. However, as time went on, more and more things were cut. The experts were sweating with nervous palms and staring at the tool, I was worried that the tool would be damaged due to overheating, but after more than ten minutes, the tool was still intact and there was no sign of overheating at all.

An hour later, the CNC machine tool finished its work, and the cutter was still intact. Zhang Ming curiously approached the cutter and stretched out his finger. The distance between the finger and the cutter was very close, and it seemed that he was about to arrive. He didn't feel the heat in his imagination, so Zhang Ming put his finger on the cutter directly. When his finger touched the cutter, Zhang Ming jumped up and quickly retracted his finger, Looking at the knife in horror.

Other people think that Zhang Ming is hot. Most normal people think that a lot of heat will be produced in the cutting process. This is a common sense, just like one plus one equals two. There is no doubt about it.

"Deputy group leader Zhang, you are too upset. You must be very busy with the cutting tools just after cutting. At least there are several hundred degrees of high temperature, which will burn people. But it's strange to say that the cutting tools don't see the signs of overheating. What's the matter? Is it a new type of alloy Other experts frowned and said, as they spoke, they approached Zhang Ming to see if his finger was seriously scalded.

Zhang Ming stretched out his finger, shook it in front of the experts, and said, "ladies and gentlemen, I'm not scalded. There's nothing wrong with my finger."

"Then why did you react that way?" The experts asked suspiciously.

Zhang Ming said, "because the cutting tool is cold, I won't cheat you. You can try it yourself." Although Zhang Ming can't believe it's true, he can't help but believe it.

Driven by curiosity, the experts came over one after another and reached out to touch the knife. Everyone was very cautious. When the first person touched it, he subconsciously retracted his fingers, then touched it again, and then exclaimed, "it's really cold. What's the matter?"

Other experts also went to touch the cutting tool. Yes, it was really cold. After a high-intensity cutting without using coolant, the cutting tool was not only not overheated, but also cold. This was followed by the discovery of alien like, shocking.

Is it because the machine tool cooled naturally after it stopped?

In order to verify the idea in their hearts, the experts started the CNC machine tool again and began to carry out high-strength cutting. This time, they chose the most difficult cutting, cutting a high-strength alloy into extremely complex parts with high precision requirements, cutting a large number of alloy metals, which is a great test for CNC machine tools and cutting tools.

When it was finished, the experts could not wait to touch the knife. Although they were very hearty, they still felt it hard. Then all the experts were confused, and the knife was cold.

One of the experts said: "even if it's rubbing the palm, if it's fast, it feels hot, not to mention the high-speed cutting tool, why is it cold?"

Su Yang said faintly: "after my improvement, the cutting tool is not only heat-resistant, but also extremely sharp, with high precision and long service life. It is estimated that it can be used for 50 or 60 years."

Bang... Bang

The experts fainted!
