"Alright, it worked!"

When the last curve on the process document was processed, Fan Shibin couldn't hold back the excitement in his heart and shouted loudly.

"Whoa," the workers at the scene applauded enthusiastically.

From the beginning of the first cutting knife to the present, a full two days and two nights have passed, and the people of the entire research team, including Zhu Tiejun, have not left the scene for a single step. Meals are delivered from the cafeteria, and people can find a corner to squint for a while when they are sleepy. Anyway, it's a summer day, so you can sleep with a mattress on the ground.

Zhu Tiejun didn't know much about technology, but he was always on the scene and helped solve various problems at any time. The role of the leader's presence is very obvious, at the very least, the specifications of the meals delivered by the canteen are much higher, and they are all hot meals, and there is no delay at all.

Chen Weiguo, Zou Shicheng and other factory leaders will also come to the site every day to take a walk and ask about the cold and warmth. This tackling of key problems is a political task issued by the Department of Light Chemistry, and the factory attaches great importance to it. After Chen Weiguo visited the site several times, he solemnly announced that the factory had decided that if the key research was successful, the main personnel participating in the research would be given a bonus of 100 yuan each, and the auxiliary personnel would also be rewarded with 30 or 50 yuan. As soon as this news was released, it was immediately applauded by the personnel involved in tackling key problems.

Lin Zhenhua and Hu Yang were also on site, and their task was mainly to solve technical problems. The curves they mathematically come up with need to be realized by the workers on the machine tools, so the communication between the two sides is very important. When he has nothing to do, Yan Yuanhe will also come over to chat with them and discuss some machining problems. However, when it comes to information related to national defense equipment, Hu Yang will use the excuse to walk away, showing that he is unwilling to meddle.

Peng Gang, Zhou Houcheng and Sun Changchang are naturally the main force of the entire processing work. According to the process requirements, this shaft needs to be processed alternately between a heavy-duty horizontal lathe and a gantry milling machine, and a local quenching treatment is also carried out in the middle, which is very complicated. Several technicians have their own apprentices, who can help do some manual work, such as lifting the workpiece up and down, but the final clamping positioning, the apprentices' skills are not enough, and they have to wait for the master to check.

After two days and two nights of cutting operations, several masters stayed up until their eyes were red. But that's what they do, their eyes wide red and staring at the workpiece on the workbench to make sure the machining process is perfect.

Yan Yuanhe witnessed the entire processing process with his own eyes, and he saw it very clearly, and the skills of several senior technicians can only be described as breathtaking. It is also thanks to such technology, otherwise, no matter how good the curve of Populus euphratica is, it cannot be realized on the machine tool, and it is in vain. In Changhong Machinery Factory, there are several such high-level technicians, but unfortunately there is no such high-precision processing work to let them show their talents.

What can we do to get Xiaolin and Populus euphratica to us? Yan Yuanhe depressedly thought of bad ideas.

"Don't worry, we'll have to check again." Zhou Houcheng stopped the apprentices who were about to remove the workpiece from the fixture, turned to Sun Changyuan and said, "Master Sun, you come and touch it for me to see if there is any problem." ”

Sun Yuanyuan stepped forward and gently pushed the spindle stuck on the clamp to make it turn. His other hand, resting on the surface of the spindle, felt every slight difference.

Suddenly, Sun Changyuan stopped rotating the spindle, he touched a certain position of the workpiece with his hand for a while, and then turned back to Zhou Houcheng and beckoned: "Master Zhou, you come and touch it, it seems that there is a little bit of difference here." ”

Zhou Houcheng walked over, like Sun Yuanyuan, groping with his hands on the workpiece. After a while, he smiled and said to Sun Changyuan: "Master Sun, it's still up to you." I touched it just now, but I didn't touch it. ”

Sun Changyuan said modestly: "Where is it, you are too tired and your hands are numb, right?" ”

Zhou Houcheng nodded: "It's not that my hands are numb, it's that I'm old, and it's not good." Here, wait for me to stab again. ”

Sun Changchang turned his head and saw his son Sun Xiaodong standing behind him, so he beckoned and said, "Xiaodong, come here, before Master Zhou has no car, you can also touch it." ”

Sun Xiaodong followed his father's example, and also stretched out his hand to grope on the workpiece, for a long time, but there was only a confused look on his face. Sun Changyuan slapped him on the head and scolded: "If you invest in the world, you know how to play." Come, I'll tell you, you touch this place......"

He took his son's hand and let him feel it repeatedly on the workpiece, and finally, Sun Xiaodong shouted happily: "I felt it, it's a little off here." ”

Zhou Houcheng smiled slightly: "Old Sun, there is a successor." ”

Sun Changyuan showed a hint of relief on his face, but he said: "What kind of successor, it is much worse than when I was young." ”

After saying this, he took out a pencil from the pocket of his overalls and scratched it on the workpiece, and the place he drew was exactly where he needed another cut.

Zhou Houcheng walked to the lathe, adjusted the position of the shunting tool, and pressed the button to start the lathe. The spindle flew around, and the turning tool rubbed lightly on the axle, bringing up a hair-thin iron filing. Then, Zhou Houcheng stopped the lathe and nodded to Sun Changyuan with a smile: "Okay." ”

"Master Zhou's technique is excellent, and he can solve the problem with one knife." Sun Changchang said admiringly.

The apprentices rushed up, only to see that the path that Sun Changyuan had drawn with a pencil just now was gone, and the rest of the place was unscathed. Everyone has opened their eyes and knows that there is still a long way to go between their skills and their masters.

The turning and milling operations are completed, and the next step is to carry out fine grinding on the grinding machine to make the surface size of the workpiece fully meet the design requirements. After the finishing was completed, Fan Shibin took several technicians to repeatedly inspect the machined shaft, including using a hardness tester to test the surface hardness, using a dial gauge to check the coaxiality and so on. After a series of inspections, Fan Shibin officially announced: "The ice machine spindle is successfully processed!" ”

According to the requirements of the Light Chemical Department, Changhong Machinery Factory forged a total of four blanks, which can be replenished at any time when the processing fails. As a result, Hanhua Machinery Factory only used one blank and processed a qualified spindle.

The installation of equipment for the second fertilizer plant is also nearing completion, and now it is waiting for the installation of these two 210,000 ice machines. Xie Chunyan has been staring at the installation site, and after hearing the news that the spindle processing of the Hanhua factory was completed, she immediately asked the personnel of the Hanhua factory to rush over with the spindle immediately to participate in the installation and commissioning of the 210,000 ice machine.
