When it was time to work the night shift at night, Duan Yun came to the workshop on time.

Today is a very critical day for Duan Yun.

According to the agreement with those masters last night, Duan Yun may be able to get the processed parts tonight.

Han Zhonglai was still more than Duan Yun, and he had already appeared at the workstation.

However, unlike before, Han Zhong did not start the machine and start working, but squatted next to the machine and was busy with something.

"Master. Duan Yun stepped forward and said hello to Han Zhong.

"Just in time, come and help. Han Zhong pointed to the tin box in front of him with his finger and said to Duan Yun, "Grease all the parts with butter." ”

"Uh. Duan Yun saw at a glance that what was in the tin box was the finished product of the modified parts drawn on his drawings, and his heart was suddenly happy, and then he squatted in front of Han Zhong and said in surprise: "Master, have it all been made so soon?"

"Lao Xu and miller Xiao Liu in the day-shift caster workshop also helped to rush out, and Master Chen also helped with heat treatment. Han Zhong carefully buttered the gears and said without raising his head.

"Definitely, definitely. Duan Yun patted the two packs of cigarettes he was carrying in his trouser pocket with his hand and said with a smile.

Duan Yun can see that cigarettes are still 'hard currency' in the factory, and if the master is not there in the future, as long as the 'ammunition' is sufficient, he should still be able to do a lot of things.

Rich natural people are popular, and if there is no friendship, you can still find someone to help if you have benefits.

"Xiao Duan, to be honest, can your modification plan really improve processing efficiency?" Han Zhong gently placed a well-oiled sliding gear in another empty iron box, and looked up and asked Duan Yun.

"Master, didn't you see my modification drawings last night?" Duan Yun replied.

"I don't understand it all," Han Zhong shook his head, and then said: "I can understand the general meaning, but if this kind ......of technical transformation is a little wrong, if it is not done well, it will be wasted." ”

"It's okay, failure is success success!"

"Hey, I'm about to leave anyway, so I'm going crazy with you young people in the end!" Han Zhong said with a light sigh.

The expressions of the master and apprentice gradually became more and more focused.

Time passed minute by minute, and the squad leader just came over to take a look and left without asking much, after all, Han Zhong was the master in the factory, and he took good care of him up and down, even if he slept in the workshop at night, no one cared about him.

Opening the iron casing of the lathe's gearbox and feed box, Duan Yun was ready to add these gears.

Installing the gears seems simple, but in fact it is not an easy task, Duan Yun first needs to test the occlusion of each gear, and due to the limited space in the original gearbox, Duan Yun has tried his best to design the parts reasonably enough, but still needs to make some changes to the chassis shell.

Han Zhong found an electric drill and a small grinder, and tossed for a while to change the shell.

Until half past three in the middle of the night, Duan Yun had completed most of the modification, and the master and apprentice were already a little tired by this time.

Without waiting for the master's instructions, Duan Yun got up and took the half-drunk teacup of the master and went to the water room to add hot water.

At this time, Yun's mood was undoubtedly excited.

The next work will be much easier, you only need to install the two servo motors on the front and rear sides of the lathe, and then debug the wiring and power supply, and the lathe can be started.

Duan Yun was secretly glad in his heart to meet such a good master, if it weren't for Han Zhong, he would not have been able to find someone to help him process parts so smoothly, and in addition, various tools, wires, servo motors and other things could not be borrowed from the warehouse.

In any case, the current Duan Yun is about to see the dawn of victory.

After just a short rest, the master and apprentice continued to start the rest of the installation work.

The grinder and the electric drill took turns, and Han Zhong's eyes were also a little excited at this time.

After more than two hours, the sky outside had begun to show the whiteness of the fish's belly, and Duan Yun's first machine tool modification was completely completed.

The master and apprentice did not rush to debug immediately, but walked out of the door of the workshop together, found a place to smoke and rest for a while.

"Thanks to you for helping me today, master, otherwise, I wouldn't know that this technical transformation could be completed in the Year of the Monkey. Duan Yun handed Han Zhong a phoenix, took out a match to help him light it, and said with a grateful face.

"Do you know why I helped you this time?" asked Han Zhong after taking a puff of his cigarette.

"Because I'm your apprentice!" Duan Yun said with a smile.

"Hehe, that's really just one aspect. Han Zhong smiled when he heard this, and then said: "Actually, the main thing is that I feel that you are a bit similar to me when I first entered the factory when I was young. ”

"Huh?" Duan Yun was stunned when he heard this.

"I came to work in the factory just after junior high school...... Han Zhong pondered for a while, and then said: "...... Other apprentices take three years to become regular, I can be in the workshop in half a year, and I also participated in the factory-wide skills competition, won the third place in the lathe group, beating many masters, that medal is still in my home......"

"Amazing!" Duan Yun praised when he heard this.

"But I was also a restless master at that time, and I felt that it was too boring to process some simple parts on the lathe every day, and at that time, the factory focused on the production of single hydraulic struts, but the quality was not as good as it is now......" Han Zhong squinted his eyes and took another puff of cigarette, and said: "Later, after a long time, like you, I moved the idea of modifying the lathe......

"It seems that the master is a real master. Duan Yun said with a smile and a thumbs up to Han Zhong.

"What a fart!" Han Zhong pouted, and then said: "It took me a month to modify the lathe in front of me, but after less than half an hour of operation, the main motor of the lathe was burned due to too much overload......

"Poof. Duan Yun almost laughed out loud when he heard this, and then sighed: "This is really a tragic story......

"Hey, at that time, the factory was just built and was very poor, I was detained by the public security for a week because of the crime of destroying state-owned assets by modifying the lathe without authorization, and finally the old factory director personally came forward to intercede and trust me out, and the job was not lost, I am grateful to him all my life...... But since then, I have never dared to think of modifying the equipment......" Han Zhong said this, with a look of emotion.

"Master, don't worry, I'll take care of something happens. Duan Yun patted his chest and said.

"Pull it down, I'm your master, it's not your turn to take responsibility, if I really don't want to take this responsibility, I won't even let you touch the side of this lathe!" Han Zhong threw away the cigarette butt in his hand and stepped on it, and said: "I just want to understand the knot in my heart when I was young, speaking of which, this time it was actually me who stained your kid's light, even if I failed, it doesn't matter, I'm an old man at most in the factory, who can do anything to me?"
