In the evening, after Duan Yun came to work in the workshop, he began his work of testing the newly modified lathe.

The notice of the technical transformation competition has been sent to each workshop, a workshop in order to facilitate the technical department of people to come to a test, but also specially vacated an idle lathe for modification, during the day there are already many technicians to disassemble the shell for testing, and at night, it has become Duan Yun's exclusive station.

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

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

Now that Gao Lei was fired from the factory and detained at the police station, Duan Yun has become the boss of the night shift team in a workshop, and many young workers are quite respectful when they see him.

This is actually a very natural thing, Duan Yun fought fiercely, and he was a celebrity in front of the secretary in the factory, whether it was the workshop director or the squad leader, he had to give him some face, and more importantly, Cui Lin Leizi and others made a lot of money from Duan Yun, and after the matter spread out in the night shift team, other Gao Lei's younger brothers also began to plan to follow Duan Yun's side.

Duan Yun just said that he needed help, and the young workers on the night shift came up hula and took the initiative to help Duan Yun disassemble the shell.

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

It took less than 20 minutes to install all the modified lathe workpieces in place, and finally after smearing some butter, it was done.

Although Duan Yun was full of confidence in his modification technique, when it came to the formal test, he still felt a little apprehensive in his heart.

In addition, this time Duan Yun processed the tooth embryo, which is more difficult than the previous stigma, and the tooth embryo is also the workpiece mainly processed by the lathe worker in the current workshop.

"Buzz!"

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

While the spindle rotates, it passes through the bridge gear to drive the smooth rod next to it, and the worm on the smooth rod drives the worm gear and connects the longitudinal cam on the worm gear,...... By means of a limit switch and an electromagnet, the cut steel blank placed on the angle iron is quickly pushed against the spring chuck in front of the spindle and is fixed, and then the longitudinal tool is fed to the specified position.

The distance and action of modification may sound complicated, but in fact, this series of actions all takes place in a breathing time.

"Thorn!"

A sharp metal cutting sound sounded, dark blue iron filings rolled off in circles, and a finely turned sleeve was quickly cut.

"Click!"

The lever pushes the transverse turning tool forward, the machined workpiece is partially cut, the spring chuck is released, and the scrap rolls down into the tin box located under the spring chuck.

"Brother Duan is too good!"

"Awesome! This is called technology!"

"I just said that as soon as Brother Duan made a move, the scum of the technical department could only bow down!"

Seeing that the first workpiece was quickly processed, the young workers who were watching next to him suddenly made a sound of sycophancy.

Duan Yun's modified lathe this time is similar to the basic principle of the last time, but in fact, because the speed of the new lathe is much faster than the previous old lathe, in addition, the automatic processing program set by Duan Yun this time is divided into two steps: rough turning and fine turning.

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

"Bang bang!" suddenly burst into applause.

Duan Yun glanced at his watch, but he didn't mean to close the lathe

Although the surrounding young workers have been stinging with 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 him gradually dispersed, and Duan Yun still watched the operation of the automatic lathe.

In Duan Yun's view, in addition to the 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 points, Duan Yun changed the cutter head to YT30 cutter head and started fine turning.

It wasn't until four o'clock in the morning that Duan Yun finished the test, and after closing the lathe, Duan Yun touched the iron shell of the lathe again, and felt that the temperature was normal, and then he breathed a sigh of relief.

In four hours, Duan Yun processed eighty-one tooth embryos, and all of them were qualified, which made Huang Haitao, the squad leader who had been watching from the side, simply dumbfounded!

You know, at present, the most skilled lathe in a workshop to process this kind of tooth embryo, even if it is only rough turning a day, it is absolutely not more than 30, if you count the time spent on fine turning, then a person can make 14 or 5 of these specifications in a day!

Duan Yun made eighty tooth embryos in one hour, and if it was calculated according to eight hours, it would mean that the efficiency of Duan Yun's automatic lathe was ten times higher than that of the most skilled old workers in the workshop!

Although the efficiency of the previous modified SL lathe has shrunk by half by 20 times, the difficulty of the processed workpiece is different, and this lathe can complete all the procedures from rough turning to fine turning at the same time, so the increase in efficiency by ten times is already quite an amazing number!

If Huang Haitao thought that the SL lathe modified by Duan Yun was stained with the light of his master Han Zhong, then this lathe modification is undoubtedly all the credit of Duan Yun alone, and it is difficult to modify the new lathe, so in Huang Haitao's opinion, Duan Yun is indeed technically two brushes.

"I think the champion of this technical transformation competition must be yours. Huang Haitao said with envy.

"It's not that easy. Duan Yun smiled when he heard this, and then said, "Are you the chief engineer of those technicians in our factory?"

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

Obviously, in Huang Haitao's opinion, Duan Yun's skills are very high, but he is definitely not as good as the chief engineer.

"When the time comes, leave it to fate. Duan Yun smiled and continued, "Okay, let's do it today." ”

"Put your things here, I'll call someone to come and help you clean up." Huang Haitao said flatteringly to Duan Yun.

"Okay, then it's troublesome for squad leader Huang. Duan Yun smiled at Huang Haitao, turned around and walked outside the workshop door to smoke......
