Chapter 120 The Night Shift Boss
In the evening, after Duan Yun came to work in the workshop, he began to test the newly modified lathe.

The notice of the technical improvement competition has been sent to all workshops. In order to facilitate the people from the technical department to come and test, the first workshop specially set aside an idle lathe for modification. During the day, many technicians have already disassembled the casing for testing. And at night, it became Duan Yun's exclusive workstation.

With less than two weeks to go before the technical transformation competition at the end of the month, Duan Yun decided to make preparations in advance.

After saying hello to the monitor, Duan Yun took tools to disassemble the casing, Cui Lin and Lei Zi also put down their work and came to help Duan Yun.

Now that Gao Lei was expelled from the factory and detained at the police station, Duan Yun has become the leader of the night shift team in a workshop. Many young workers are quite respectful when they see him. They open their mouths to call Duan Ge, and they are responsive .

This is actually a very natural thing. Duan Yun fights fiercely, and he is a popular person in front of the secretary in the factory. Whether it is the workshop director or the monitor, he must give him some face, and more importantly, Cui Linleizi, etc. He made a lot of money from Duan Yun, and after the news got out on the night shift team, other Gao Lei's younger brothers also started planning to hang out with Duan Yun.

Duan Yun just said that he needed help, and the young workers on the night shift rushed up and helped Duan Yun dismantle the shell.

Taking out the refitting workpiece that had already been processed from the tool cabinet, Duan Yun quickly started the assembly work.

The few who came to help worked very hard. It took less than 10 to [-] minutes to install all the modified lathe workpieces in place. Finally, after smearing some butter, it was considered a success.

Although Duan Yun was full of confidence in his modified technology, when it came to the formal test, he still felt a little nervous.

In addition, what Duan Yun is processing this time is the tooth blank, which is more difficult than the previous stigma. In addition, the tooth blank is also the main workpiece processed by the lathe workers in the first workshop.

"Buzz!"

The moment the power is turned on, the main motor rotates rapidly.

While the main shaft rotates, it passes through the bridge gear and drives the polished rod next to it. The worm on the polished rod drives the worm gear and connects to the longitudinal cam on the worm gear. Using limit switches and electromagnets, the cut steel blank placed on the angle iron is quickly The spring chuck against the front of the spindle is fixed, and then the longitudinal knife is fed to the specified position.

The distance and movement of the modified sound a bit complicated, but in fact this series of movements all take place in one breath.

"prick!"

There was a sharp metal cutting sound, dark blue iron filings rolled down in circles, and a precision-turned sleeve was quickly cut.

"Click!"

The lever pushes the horizontal turning tool forward, the processed workpiece part is cut off, the spring chuck is released, and the waste also rolls down into the iron box below the spring chuck.

"Brother Duan is too good!"

"Awesome! This is called technology!"

"I said that once Brother Duan makes a move, the scum in the technical department will have no choice but to bow down!"

Seeing that the first workpiece was processed quickly, the young workers who were watching by the side immediately flattered.

The lathe modified by Duan Yun this time is similar to the basic principle of last time, but in fact, the speed of the new lathe is much faster than that of the old lathe before. In addition, the automatic processing program set by Duan Yun this time is divided into rough turning and fine turning. In two steps, a large number of tooth blanks are produced by rough turning first, and then the tool head is changed manually, and the amount of cutting tool is adjusted for fine turning. Therefore, Duan Yun has made a lot of new improvements to the new lathe this time. As far as the automatic modification of the lathe is concerned, the technical content is much higher.

"Brother Duan, the size is completely qualified." At this time, Cui Lin took out a processed workpiece and measured it, then said with a smile on his face.

"Papa papa!" There was applause all around.

Duan Yun glanced at his watch, but didn't intend to turn off the lathe.
Although the young workers around have been flattering Duan Yun, Duan Yun knows that the experiment is not over yet.

From twelve o'clock in the evening to two o'clock in the morning, the other young workers around gradually dispersed, but Duan Yun was still watching the operation of the automatic lathe.

In Duan Yun's view, in addition to efficient operation of a mature technical transformation project, it is more important to ensure the long-term safe and stable operation of the machine tool.

After two o'clock, Duan Yun replaced the cutter head with a YT30 cutter head and started finishing turning.

Duan Yun didn't finish the test until four o'clock in the morning. After turning off the lathe, Duan Yun touched the iron shell of the lathe again. After feeling that the temperature was normal, he breathed a sigh of relief.

For four full hours, Duan Yun processed 81 tooth embryos, all of which were qualified, which stunned Huang Haitao, the monitor who had been watching by the side!
You know, at present, the most skilled lathe workers in the first workshop can process this kind of tooth embryos, even if they only process rough lathes, they will definitely not exceed [-] per day. Fourteen or five qualified tooth embryos of this specification!
Duan Yun made [-] tooth embryos in an hour. If calculated according to eight hours, it means that the efficiency of Duan Yun's automatic lathe is ten times higher than that of the most skilled old workers in the workshop!
Although the [-]-fold efficiency of the previously modified SL lathe has shrunk by half, the difficulty of the processed workpieces is different, and this lathe can complete all procedures from rough turning to fine turning at the same time, so the ten-fold increase in efficiency is quite amazing. The numbers are up!
If Huang Haitao thought that the SL lathe modified by Duan Yun was under the influence of his master Han Zhong, then the modification of the lathe is undoubtedly due to Duan Yun alone, and it is more difficult to modify the new lathe , so in Huang Haitao's view, Duan Yun's technology is indeed two brushes.

"I think you must be the champion of this technological innovation competition." Huang Haitao said enviously.

"There's no such thing as easy." Duan Yun smiled after hearing the words, and continued: "You are the chief engineer of our factory, and everything is just for nothing?"

"That's true, but I heard that the chief engineer and deputy chief engineer will not participate in this competition. If they participate, then who can compete with them." Huang Haitao shook his head and said.

Obviously, from Huang Haitao's point of view, Duan Yun's skills are very high, but he is definitely not as good as the chief engineer.

"Let's resign ourselves to fate at that time." Duan Yun smiled, and then said: "Okay, let's leave it like this for today."

"Put your things here, I'll ask someone to come and help you clean it up." Huang Haitao said to Duan Yun in a fawning manner.

"Okay, then I will trouble Squad Leader Huang." Duan Yun smiled at Huang Haitao, turned around and walked outside the workshop door to smoke...
