At this time, Chen Zhen was holding up the newly processed aluminum alloy gear and checking it carefully with a magnifying glass. Because he was too focused, he did not notice the arrival of Lu Jiadong and the others.

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

Standing next to him, wearing blue kung fu, the old master with gray hair was named Li Deshun. He was the gold-medal machine tool worker in the factory and the one mentioned by the Chen brothers and sisters before. The reason why he was called a machine tool worker is because no matter what machinery the factory is, he can operate and repair it, and both the accuracy and technology are particularly high. At this time, he was disbelief and snatched the thing from Chen Zhen's hand and looked at it. Then he called it in an incredible tone:

"How is that 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 working on machining for so many years, and I still have confidence. If you want to talk about the problem, is it because the blanks given by the Industrial Department have defects!"

After hearing Master Li's words, Chen Zhen just frowned, neither affirming nor denying it, but Chen Zhen's attitude was so anxious that Li Deshun:

"Director Chen, are you not at ease with 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 that. When Master Li speaks, the unique pride of military factory workers is hanging on his face:

"The quality of civilian factories is not very good. A few years ago, the city's industrial bureau gave our factory a batch of steel billets and asked us to help with the processing. As a result, the billets were cut in two cuts. At that time, Director Chen, you were still in the workshop, so you should be very clear."

"Dad, Master Li is right. It must be that there is a problem with the blanks given by the Industrial Bureau, otherwise this problem would not occur with our technology!"

As soon as Li Deshun finished speaking, Chen Zihao echoed that military factories, as an industry that the country has focused on and supported, have always been synonymous with technology and quality. Because of this, the employees of military factories have an innate sense of superiority to civilian factories. Therefore, when people around him heard Li Deshun and Chen Zihao's words, they kept nodding, feeling that Li Deshun and Chen Zihao's words were justified.

After hearing what Li Deshun and others said, Chen Zhen sighed helplessly: "There is no problem with the blank!"

“How is this possible…”

"Yesterday I thought the same as you guys, is there something wrong with the blank?" Before Li Deshun finished speaking, Chen Zhen interrupted him and continued: "So, I went to the quality inspection department, laboratory department and heat treatment workshop last night to see if there is any problem with the blank quality. After inspection, they told me that there is no quality problem with the blank!"

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

"So, 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 as he looked at the few people feeling a little depressed, Chen Zhen said loudly: "Don't think too much, let's just treat it as a chat. You people are the top students in various positions in our factory. Chairman Mao said that practicing true knowledge will lead to sharp knowledge. The eyes of the masses are sharp. Don't hide any ideas you have, just say it out!"

Chen Zhen's words suddenly mobilized everyone. A few people began to discuss the processing technology issues in one word, such as heat treatment, forging, and casting. Anyway, the more they talked, the more advanced they became, the more technical difficulty became higher and higher. According to this trend, these aluminum alloy workpieces should almost be crushed into powder and rebuilt.

Seeing this situation, Chen Ziyue, who was standing next to her, 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!" Before Lu Jiadong could answer, Fatty Luo, behind him, asked with a smile.

"Yeah!" Chen Ziyue just responded softly, ignored Fatty Luo, but continued to ask Lu Jiadong: "If you know, just say it, don't be afraid!" After Chen Ziyue said this, she felt something was wrong, so she added:

"If you are afraid, just tell me and I'll tell you!" Chen Ziyue seemed a little anxious. There was nothing she could do about it. Looking at her father who was covered in blood, how could she not feel sorry for her daughter, but she couldn't help much, so she could only count on Lu Jiadong.

Looking at Chen Ziyue's eyes looking at her father worriedly, how could Lu Jiadong not understand the thought of a daughter feeling sorry for her father? So Lu Jiadong said to Chen Ziyue in a low voice:

"If that's right, it should be a problem with the cutting fluid!"

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

"Aluminum alloy finishing generally uses kerosene and turpentine oil as cutting fluid, or mixing the two can also be done!" Since Chen Zhen asked, Lu Jiadong answered truthfully

"Kerosene! Turpentine!" Chen Zhen's eyes suddenly lit up after hearing Lu Jiadong's words, as if he understood something. He quickly ordered Chen Zihao next to him:

"Go and bring kerosene!"

"Director Chen, this is the first time I have heard of using kerosene as cutting fluid. Can this work?" Li Deshun was a little suspicious.

"How can you know if it's okay if you don't try it?" Chen Zhen was obviously determined. Since Chen Zhen was so persistent, Li Deshun couldn't say anything.

In order to deal with the power outage, the factory specially prepared kerosene lamps, so kerosene is not difficult to find. In a blink of an eye, Chen Zihao brought kerosene and replaced the cutting fluid in the machine with kerosene. Then, at Chen Zhen's instruction, he started the machine. With the roar of prop cutting, an aluminum alloy gear was quickly completed.

Chen Zhen quickly took the gear in his hand and carefully looked at it with a magnifying glass. He found that all the pinholes that were like a stubborn disease had disappeared. He couldn't help but scream excitedly:

"Success! Success!" Then he turned around and looked around the people around him. Because of his excitement, he forgot who said the cutting fluid question, so he asked the people around him:

"Who is the first to say that it is the cutting fluid!"

Li Deshun, Chen Zihao and others looked at me, and I looked at you, no one answered. At this moment, Chen Ziyue, who was standing next to her, shouted in great excitement:
Chapter completed!
