At this time, Chen Zhen was holding the freshly processed aluminum alloy gear, carefully examining it with a magnifying glass, because he was too focused, he didn't notice Lu Jiadong's arrival.

"Master Li, there are still pinholes on the workpiece!" Chen Zhen put down the things in his hand and rubbed his bloodshot eyes.

Standing next to him, the old master wearing blue kung fu and gray hair is named Li Deshun, who is a gold medal machine tool worker in the factory, and also the master Li in the mouth of the Chen brothers and sisters before, the reason why he is called a machine tool worker is because no matter what machinery in the factory, he will operate and maintain, and both accuracy and technology are particularly high, at this time he was full of disbelief, snatched the thing in Chen Zhen's hand and lifted it up to look at it, and then called in an incredible tone:

"How is it possible?" After looking at it for a while, Li Deshun raised his head and said to Chen Zhen: "Our process should be fine, I have been doing machining for so many years, and I still have this confidence, if you want to talk about the problem, is there a defect in the blank given by the Department of Industry!"

After listening to Master Li's words, Chen Zhen just frowned, neither affirming nor denying, but Chen Zhen's attitude made Li Deshun anxious:

"Director Chen, are you still not worried about the technology and quality of the military factory?" Although Chen Zhen is the manager of the labor service company, he has the title of workshop director in the factory, so Master Li calls him so, and when Master Li speaks, the pride unique to the workers of the military factory hangs on his face:

"The quality of the civilian factory itself is not very good, a few years ago, it was also the city's industrial bureau to give our factory a batch of billets, let us help with processing, as a result, those blanks cut two knives and broken, at that time Director Chen, you are still in the workshop, should be very clear. ”

"Dad, Master Li is right, there must be a problem with the blank given by the Industrial Bureau, otherwise this problem will not occur with our technology!"

As soon as Li Deshun's voice fell, Chen Zihao echoed that the military factory, as an industry with key investment and support from the state, has always been synonymous with technology and quality, and because of this, the workers of the military factory have an innate sense of superiority over the civilian factory, so the people around listened to Li Deshun and Chen Zihao's words, and they couldn't stop nodding their heads, feeling that Li Deshun and Chen Zihao's words made sense.

Chen Zhen listened to the words of Li Deshun and others, and sighed helplessly: "There is no problem with the blank!"

"How is this possible?"

"Yesterday I thought the same as you, is there a problem with the blank!" Before Li Deshun finished speaking, Chen Zhen interrupted him and continued: "Therefore, I went to the quality inspection department, laboratory department and heat treatment workshop last night to ask them to see if there is a problem with the quality of the blanks, and they have been inspected and told me that these blanks have no quality problems!"

Chen Zhen's words were like a basin of cold water, poured on everyone's heads, but Chen Zhen did not stop, but changed his tone and said in a very firm tone:

"So, or something went wrong in our processing, Master Li, you are the best machining master in our factory, think about it again, is there something wrong in our link!"

Then Chen Zhen looked around again, and saw that several people were a little depressed, Chen Zhen said loudly: "Don't think too much, let's just take it as a small talk, you people are the top people in our factory, ** said, practice brings true knowledge, the eyes of the masses are bright, don't hide any ideas you have, just say it!"

Chen Zhen's words mobilized everyone at once, and several people began to discuss the problems of processing technology, what heat treatment, forging, casting mold, anyway, the more you talk about it, the higher and deeper the technical difficulty is, according to this trend, these aluminum alloy workpieces should almost be ground into powder and remanufactured in the furnace.

Seeing this situation, Chen Ziyue, who had been standing next to him and had not spoken, pulled Lu Jiadong's sleeve and asked in a low voice:

"Lu Jiadong, do you know what the problem is?"

"Comrade Xiao Chen, your father seems to be a cadre!" Without waiting for Lu Jiadong to answer, Luo Fatzi behind him asked with a smile.

"Hmm!" Chen Ziyue just responded softly, and didn't pay attention to the fat man, but continued to ask Lu Jiadong: "If you know, you can say it, don't be afraid!" After Chen Ziyue finished saying this, he felt that something was wrong, so he added:

"If you're afraid, just tell me, I'll help you say it!" Chen Ziyue looked a little anxious, there was no way, looking at her father whose eyes were bloodshot, how could she not feel distressed as a daughter, but she couldn't help much, so she could only count on Lu Jiadong.

Looking at Chen Ziyue's worried eyes looking at his father, how could Lu Jiadong not understand that a daughter felt sorry for her father, so Lu Jiadong whispered to Chen Ziyue:

"If that's right, it's the cutting fluid!"

"Cutting fluid? why?" Although Lu Jiadong's voice was small, it was still heard by Chen Zhen, although the person next to him was also saying, but those problems were too complicated, Chen Zhen, who had been the director of the workshop, did not believe that ordinary agricultural machinery gears would have such complex technical problems, so when Lu Jiadong said the simple problem of cutting fluid, it suddenly aroused his interest.

"Aluminum alloy finishing generally uses kerosene and turpentine as cutting fluids, or a mixture of the two!" Since Chen Zhen asked, Lu Jiadong answered truthfully

"Kerosene! turpentine!" Chen Zhen listened to Lu Jiadong's words, his eyes suddenly lit up, as if he understood something, and hurriedly instructed Chen Zihao next to him:

"Go get the kerosene!"

"Director Chen, it's the first time I've heard of using kerosene as cutting fluid, can this work?" Li Deshun was a little skeptical.

"How do you know if you can't do it if you don't try!" Chen Zhen obviously made up his mind, since Chen Zhen was so persistent, Li Deshun couldn't say anything.

In order to cope with the power outage, the factory specially prepared kerosene lamps, so kerosene is not difficult to find, in the blink of an eye, Chen Zihao took the kerosene, replaced the cutting fluid in the machine with kerosene, and then under the instruction of Chen Zhen, started the machine, with a roaring sound of prop cutting, an aluminum alloy gear was quickly processed.

Chen Zhen hurriedly took the gear into his hand, carefully checked it with a magnifying glass, and found that all the pinholes that were like stubborn diseases before were gone, and he couldn't help but exclaim excitedly:

"Success, success!" Then he turned his head and looked around at the people around him, and because of his excitement, he forgot who was talking about the cutting fluid, so he asked the people around him:

"Who was the first to say that it was the cutting fluid problem?"

Li Deshun and Chen Zihao and others, you look at me, I look at you, no one answered, at this moment, Chen Ziyue, who was standing next to him, shouted excitedly:

"Lu Jiadong, Dad, it's Lu Jiadong!"

Chen Zhen couldn't help but be stunned when he heard Lu Jiadong's name, and looked back at his daughter, Chen Ziyue at this time seemed even more excited than his father:

"It's the Lu Jiadong who told you yesterday that helped repair the machine!"

As soon as Chen Ziyue said this, Chen Zhen remembered, so he came to Lu Jiadong with an arrow and held Lu Jiadong's hand tightly with both hands:

"Comrade Xiao Lu, you have helped us a lot!"

"Hmph, I don't know who said yesterday that someone was a blind cat who ran into a dead mouse!" Without waiting for Lu Jiadong to answer, Chen Ziyue on the side glanced at his father and said sourly.

After listening to Chen Ziyue's words, Chen Zhen was not angry, but said with a smile: "It's that Dad doesn't seek truth from facts, or our Xiaoyue is the best!"

Hearing her father's praise, Chen Ziyue was extremely happy, like a general who had just won a battle, and smiled brighter than all the people present.

"Comrade Xiao Lu, can't aluminum alloy use emulsion as cutting fluid?" The problem of the workpiece was solved, everyone was very happy, but Li Deshun frowned, he was taught by the master since he was a teenage apprentice, cutting metal must use emulsion, and there has been no mistake in the past few decades, but today he has planted a heel on the aluminum alloy, so he didn't understand, so he stepped forward and asked.

"Different metals need different cutting fluids when machining" Lu Jiadong saw Li Deshun asking, and he also had to answer questions: "The cutting fluid used in our factory is a medium-acid emulsion used for steel, and the emulsion contains hydrogen elements, which react with aluminum and cause pinholes in aluminum alloys. ”

"That's true!" As soon as Lu Jiadong's voice fell, Chen Zhen took the words: "I read a book before, and I also said so, but I have too many thoughts, and I have long forgotten it, if it wasn't for Xiao Lu to bring it up, I wouldn't have thought that it was the problem of cutting fluid, our factory processes steel, and there are almost no other metal alloys, and the experience in this area is indeed very lacking!"

"What is lacking has to be made up, Xiao Lu knows so much, just can teach us what kind of cutting fluid is used in other metal alloys!"

"Lao Li, what are you doing here? Could it be that you want to worship Xiao Lu as a teacher?" A master next to him who had a good relationship with him looked at Li Deshun like this, worried that he was a little out of shape, so he half-jokingly reminded him to pay attention.

Unexpectedly, Li Deshun turned his head and glanced at him: "What's wrong with apprenticeship? People are stronger than us, so we have to have a dim sum, why are you Lao Du not convinced? Why don't you even understand a hair after more than ten days!"

Although Li Deshun is old, he is a typical technical nerd, and he sincerely admires people with strong skills, but because of this, he is a person who has one thing to say and two things to say, and he is relatively poor in dealing with people, and he doesn't care if he offends people.

Chen Zhen knew that Li Deshun's shaft strength had been committed again, so he hurriedly grabbed Li Deshun: "Master Li sees that it's noon, no matter what, you can't let Xiao Lu go hungry and teach you no!"

Li Deshun thought about it and felt that what Chen Zhen said made sense, so he nodded: "Okay, just listen to Director Chen!"
