Lin Feng glanced at the direction of the gear and replied lightly: "You can see it with your eyes."

Just now, Lin Feng's thinking entered a high-speed operation state. After time slowed down, his vision could barely keep up with the gear speed.

When Wang Zhen heard this answer, his face looked even worse than eating a fly.

The gear speed is about one thousand per minute. Although it is not as good as the engine, it is simply a fantasy to observe it with the naked eye.

I still believe you said you were blind and you were fooled. You were teasing me.

Lin Feng also knew that others would not believe it, but he did see it with his eyes. Perhaps because of time travel, he strengthened all aspects. He read at a glance, had super strong learning ability, and even had visual systems that could observe things that others could not see.

"Of course, this data may not be accurate. In the past 15 seconds, the gear rotated 214 revolutions, and multiplied by 4 to 856 revolutions. The actual measured value must be a bit different. If you don't believe it, you can test it."

Wang Zhen certainly didn't believe it, so he found someone to get a signal disc for measuring the speed, preparing to expose Lin Feng's nonsense on the spot.

Soon, the signal disc was taken, and Wang Zhen personally installed the gears and then personally inspected and recorded them.

A minute passed quickly, and everyone was stunned when they looked at the numbers displayed on the signal disk.

855 turns. Damn it, it is basically the same as Lin Feng’s visual data.

Wang Zhen doesn't believe in evil, so he tests it again.

This time, it happened to be 856 reps, which is exactly the same as Lin Feng's data, and is not bad at all.

Wang Zhen was convinced, completely convinced, and his eyes looked at Lin Feng like a monster.

Zhang Tianming and Zhao Feifei next to them also showed incredible expressions. They may not understand the high-level theories, but just seeing the speed of the gears with the naked eye is simply a magical skill.

What a keen observation that requires.

After amazement, Zhang Tianming asked curiously again, "What causes the speed to slow down?"

Lin Feng did not answer positively and asked back, "You listen carefully to the sound of the gears rotating."

Everyone listened carefully, but Zhang Tianming and Zhao Feifei couldn't hear the problem.

Only Wang Zhen heard the trick, and he explained with an ugly face:

"Every three weeks the gear turns, it makes a slight squeak, lasting about 0.3 seconds."

"What does this mean?" Zhang Tianming asked hurriedly.

"It means that the oil tank at the bottom of the machine tool is out of oil, the gears are not lubricated, and there is a lack of friction loss."

Wang Zhen explained this, and Director Zhang instantly understood and cursed the worker to be lazy...

But Lin Feng next to him shook his head and expressed his own opinions.

"It's not about whether there is a lubricant or not, but about whether the lubricant is right or not."

"If I'm right, you should be using No. 3 lubricant. This lubricant has a big disadvantage, that is, it is very easy to evaporate at high temperatures of 500 degrees."

Wang Zhen personally opened the oil tank and found that there was indeed lubricant inside, but Wang Zhen was still dissatisfied. "But where this machine tool uses lubricant, it will not produce high temperatures above 500 degrees."

Lin Feng pointed to a place in the machine tool, "There is the position of the gear close to the exhaust hole of the air compression box, and the air temperature discharged from the exhaust hole in each round is around 600 degrees."

Everyone looked at it and saw a mist spraying on the gears from the exhaust hole.

This time, Wang Zhen had nothing to say.

He asked Lin Feng, "Well, Boss Lin thinks, which machine tool can make qualified parts in our factory?"

Lin Feng raised his hand and pointed to the HS_859 small machine tool placed in the corner.

Zhang Tianming and Wang Zhen looked at each other, their faces full of shock.

This machine tool is a "high-end product" that a young man from the board of directors spent 30 million to buy back abroad. However, after installing it, he found that this machine tool was nothing.

Although the parts made by this machine tool are highly accurate and hard, the size of their parts is too small, so it is impossible to process ordinary parts. They are specially used for the production of high-tech instruments.

For example, the quadrupole in a supercomputer.

How could they have a list of high-tech instruments in a medium-sized processing plant? So this machine tool has been placed in the corner and has not been used for three years.

As for the young master, he was criticized by his father and other directors of the board of directors, and he heard that he was depressed.

"Boss Lin, this HS_859 machine tool can only process parts within 6.3 cm."

Lin Feng nodded, "I know, but the parts it makes can meet the technical standards we require."

"But it's too small." Wang Zhen couldn't help but say.

In Lin Feng's order, the smallest parts are 30 cm.

"It's a little smaller, but you can assemble and combine it later."

"Assembly combination?" Wang Zhen really didn't know whether Lin Feng really didn't understand or was fake. Can the pressure resistance and pressure of assembled parts be compared with single parts?

"Only parts that are assembled at 300 degrees high temperature can meet the requirements."

"High manganese nitride? What is that?"

"Compounds of nitrogen and manganese."

Wang Zhen twitched the corner of his mouth, "Boss Lin, although I am not very professional in chemistry, I also know that nitrogen is an inert gas, and the chemical bonds between nitrogen and manganese are both regular valence bonds. How can both form chemical substances?"

"First of all, nitrogen is not an inert gas, but is relatively stable at room temperature. If placed in a specific environment, chemical reactions can still occur. Of course, the compounds synthesized after this reaction are very unstable and can easily trigger disproportionate reactions."

"Of course, nothing is absolute, especially for chemistry. To make high manganese nitride, one can first make high iron nitride, and then through the replacement reaction, an unstable compound is obtained."

"How to make high iron nitride?"
