Skilled craftsmanship

  "Alright, succeeded!"

  When the last curve on the process sheet was finished, Fan Shibin couldn't hold back his excitement and shouted loudly.

  "Bravo! Bravo!" The workers on site applauded warmly.

  From the first cut to now, two days and two nights have passed, and the entire research team, including Zhu Tiejun, has not left the scene. Meals were delivered from the cafeteria, and people who were tired would find a corner to take a nap whenever they wanted. Anyway, it's also summer now, so just spreading out a cooling mat on the ground can be enough for sleeping.

  Zhu Tiejun didn't know much about the technology, but he always stayed on site and helped solve various problems at any time. The presence of a leader had a very obvious effect - at the very least, the food sent by the cafeteria was of much higher quality, and it was all hot dishes, not delayed in the slightest.

  Chen Weiguo, Zou Shicheng and other factory leaders also came to the scene every day to ask about the situation. This time, the task was a political task assigned by the Light Industry Hall, and the factory attached great importance to it. After Chen Weiguo visited the scene several times, he solemnly announced that the factory had decided that if the task was successfully completed, the main participants would each receive a bonus of 100 yuan, and auxiliary personnel would also receive rewards of 30 or 50 yuan. As soon as this news was released, it received unanimous applause from the personnel participating in the task.

  Lin Zhenhua and Hu Yang also stayed on the scene, their main task was to solve technical problems. The curve they calculated using mathematical methods needs to be implemented by workers on machine tools, so communication between the two parties is very important. When he had nothing to do, Yan Yuan would come over and chat with them, discussing some mechanical processing issues. However, whenever it involved information related to national defense equipment, Hu Yang would make an excuse to leave, showing that he was unwilling to get involved.

  Peng Gang, Zhou Houcheng and Sun Changyuan were the main forces in the entire processing work. According to the process requirements, this shaft needs to be processed alternately between heavy-duty lathes and planer milling machines, and local quenching treatment is also required in the middle. The work was very complicated. Each technician had their own apprentices who could help with some physical labor, such as lifting the workpiece up and down, but for the final clamping and positioning, the apprentices' skills were not enough, and they had to wait for the master to take care of it.

  Two days and two nights of cutting work, several masters were so tired that their eyes turned red. But they just kept staring at the workpiece on the workbench with wide open and bloodshot eyes, ensuring that the processing process was accurate to every detail.

  Yan Yuan witnessed the entire processing process with his own eyes, and he saw it very clearly. The skills of several senior technicians can only be described as breathtaking. Fortunately, there are such techniques, otherwise, no matter how good Hu Yang's curve calculations were, they could not be implemented on machine tools, which would be a waste. In Changhong Machinery Factory, there are also several technicians with such high levels, but unfortunately, there is no such high-precision processing work to let them show off their skills.

  Think of a way to get Xiao Lin and Hu Yang over there. Yan Yuan thought gloomily, thinking of bad ideas.

  "Don't be in a hurry, we need to check again." Zhou Houcheng stopped the apprentices who were about to disassemble the workpiece from the fixture and turned to Sun Changyuan, saying: "Master Sun, come and feel it for me, see where there's still a problem."

  Sun Changyuan walked forward, gently pushing the stuck main shaft in the chuck to make it rotate. His other hand rested on the surface of the main shaft, feeling every subtle difference.

  Suddenly, Sun Changyuan stopped the rotation of the main shaft. He used his hand to feel a certain position on the workpiece for a while, then turned back to Zhou Houcheng and said: "Master Zhou, come and feel it, this place seems to be off by a bit."

  Zhou Houcheng walked over, just like Sun Changyuan, and felt around the workpiece with his hands. After a while, he smiled and said to Sun Changyuan: "Master Sun, you're still the best. I also felt it just now, but I didn't find anything."

  Sun Changyuan humbly said: "Nonsense, you're just too tired, your hands are numb, right?"

  Zhou Houcheng nodded: "It's not numbness, it's old age, I'm no longer capable. Come on, wait for me to sharpen the knife again."

  Sun Changyuan turned his head and saw his son Sun Xiaodong standing behind him, so he beckoned to him and said: "Xiaodong, come over here. Take advantage of Master Zhou not having a car yet, you also come and feel it."

  Sun Xiaodong imitated his father, also stretching out his hand to feel the workpiece, for a long time, but on his face there was only a confused expression. Sun Changyuan patted him on the head and scolded: "Good-for-nothing, you just know how to play. Come, I'll tell you, touch this place..."

  He pulled his son's hand and let him feel the workpiece repeatedly. Finally, Sun Xiaodong exclaimed happily: "I felt it out, this place is a bit off."

  Zhou Houcheng smiled slightly and said: "Old Sun, there is someone to inherit after all."

  Sun Changyuan's face showed a hint of relief, but he said, "What successor, compared to when I was young, it's much worse."

  After saying that, he took out a pencil from the breast pocket of his work uniform and drew a line on the workpiece. The place where he drew was exactly where another cut was needed.

  Zhou Houcheng walked up to the lathe, adjusted the position of the cutting tool, and pressed the button to start the lathe. The main shaft spun around, and the cutting tool lightly scraped against it, producing a thin strip of iron filings as fine as hair. Then, Zhou Houcheng stopped the lathe and nodded at Sun Changyuan with a smile: "Alright."

  "Master Zhou's skills are indeed impressive, one knife and the problem is solved." Sun Changyuan said with admiration.

  The apprentices rushed up, only to see that the lines drawn by Sun Changyuan with a pencil had disappeared, and other places were intact. Everyone was enlightened, knowing that their skills were still far behind their master's.

  The car processing is completed, and the next step is to grind on the grinding machine to make the surface size of the workpiece fully meet the design requirements. After the fine grinding was completed, Fan Shibin led several technicians to conduct repeated inspections on the processed axle, including testing the surface hardness with a hardness tester, testing the coaxiality with a thousandth table, and so on. After a series of inspections, Fan Shibin formally announced: "The ice machine main shaft processing is successful!"

  According to the requirements of Qinghua Hall, Changhong Machinery Factory forged a total of four blanks, preparing for the possibility of processing failure at any time. As a result, Hanhua Machinery Factory only used one blank and processed a qualified main shaft.

  The equipment installation work of the second fertilizer plant has also come to an end, and now it's just waiting for the installation of these two 210,000 ice machines. Xie Chunyuan has been staring at the installation site, and after hearing the news that the main shaft processing of the Hua Factory was completed, she immediately asked the personnel of the Hua Factory to bring the main shaft over and participate in the installation and debugging work of the 210,000 ice machine.
