Lin Feng glanced at the direction of the gear, and said lightly: "Eyes see." ”

Seeing with his eyes, Wang Zhen's face was more ugly than eating a fly when he heard this answer.

The gear speed is about 1,000 per minute, although it is not as good as the tens of thousands of engines, but if you want to observe it with the naked eye, it is simply a fantasy.

You say that you are blind and I still believe it, and you see it with your eyes, and you are teasing me.

Lin Feng also knew that others would not believe it, but he did use his eyes to see, perhaps because of the crossing, he strengthened in all aspects, reading books at a glance and ten lines, super learning ability, and even the visual system, he could observe things that others could not see.

"Of course, this data is not necessarily accurate, just in the past 15 seconds, the gear has turned 214 revolutions, multiplied by 4 is 856 revolutions, the actual measured value, there must be a bit of a difference. If you don't believe me, take a test. ”

Wang Zhen definitely didn't believe it, so he asked someone to get the signal disk to measure the rotational speed, and prepared to expose Lin Feng's nonsense on the spot.

Soon, the signal panel was taken, and Wang Zhen personally installed the gears, and then personally tested the records.

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

855 rpm. , it is basically the same as the data visually measured by Lin Feng.

Wang Zhen doesn't believe in evil and tests again.

This time, it was just 856 rpm, which was exactly the same as Lin Feng's data, and the score was exactly the same.

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

Zhang Tianming and Zhao Feifei next to him also showed expressions of disbelief, they may not understand the lofty theory, but just by seeing the speed of the gear with the naked eye, this is simply a god skill.

What a keen sense of observation it takes.

After being amazed, Zhang Tianming asked curiously, "What causes the speed to slow down?" ”

Lin Feng didn't answer directly, but asked, "You listen carefully to the sound of the gears turning. ”

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

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

"Every three rotations of the gear, there is a subtle squeak that lasts for about 0.3 seconds."

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

"It shows that the oil groove at the bottom of the machine tool is out of oil, and the gear is not lubricated, which is poor in friction loss."

Wang Zhen explained this, and Director Zhang instantly understood, and secretly scolded the workers for being lazy....

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

"It's not a question of whether there is lubricating oil, it's a question of whether the lubricating oil is right."

"If I'm not mistaken, you should be using No. 3 lubricant, which has a big disadvantage, that is, it is very volatile at 500 degrees Celsius."

Wang Zhen personally opened the oil groove and found that there was still lubricating oil in it, but Wang Zhen was still unconvinced, "But where the lubricating oil is used for this machine tool, it will not produce a high temperature of more than 500 degrees." ”

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

Everyone looked, and sure enough, they saw a fog sprayed on the gears from the exhaust hole.

This time, Wang Zhen had nothing to say.

He asked Lin Feng rhetorically, "Then Boss Lin thinks, what kind of machine tool can our factory make qualified parts?" ”

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

Zhang Tianming and Wang Zhen glanced at each other, and their faces were stunned.

This machine tool is a 'high-end goods' that a son-in-law of the board of directors spent 30 million yuan abroad, but when he installed it, he found that this machine tool is simply chicken ribs.

Although the parts made by this machine tool have high precision and strong hardness, the size of its parts is too small, and it is impossible to process ordinary parts, and it is specially used for the production of parts for high-tech instruments.

For example, the quadriode in a supercomputer.

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

As for the son-in-law, he was criticized by his father and the other directors of the board of directors for being indecent, and he was depressed when he heard it.

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

Lin Feng nodded, "I know, but only 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 centimeters.

"It's a little small, but it can be assembled and combined later."

"Assemble and assemble?" Wang Zhenzhen really doesn't know if Lin Feng really doesn't understand or fake, can the compressive pressure of the assembled parts be compared with the single parts?

"Only by using high manganese nitride as a fusion agent can the parts assembled at a high temperature of 300 degrees meet the requirements."

"High manganese nitride? What's that? ”

"Compounds of nitrogen and manganese."

The corners of Wang Zhen's mouth twitched, "Boss Lin, although I am not very professional in chemistry, I also know that nitrogen is an inert gas, and the chemical bonds of nitrogen and manganese are both positive bonds, how can the two form chemicals?" ”

"First of all, nitrogen is not an inert gas, but it is relatively stable at room temperature, and if it is put into a specific environment, it can still cause chemical reactions.

"Of course, nothing is absolute, especially for chemistry, to make high manganese nitride, you can first make high iron nitride, and then through the displacement reaction, you can get a less stable compound."

"So how do you make high iron nitride?"

"This involves some deep chemistry, I'll write out the production steps later, you just follow the above, it's not too much trouble. As for the related theory, three years ago, in the December issue of the journal "Exploration Chemistry", in the lower right corner of page 36, there was a paper on metal nitrides, and you can check it out if you are interested. ”
