"Thank you so much, master. Duan Yun said with a grateful face.

In fact, I am secretly glad in my heart, after all, it is indeed a crazy thing for an apprentice who has not been in the factory for a long time to engage in technical transformation, but I didn't expect that I could meet a master who was willing to accompany me to be 'crazy', which has to be said to be a kind of luck, or this Han Zhong is the first 'nobleman' that Duan Yun met after his rebirth.

"Needless to say, there are still more than two hours before the end of work, let's test the effect of the modification first. Han Zhong glanced at his watch and said,

"Hmm. Duan Yun answered, and the two returned to the workshop.

Although Duan Yun has been thinking about this technical transformation plan repeatedly for the past two days, and has scrutinized all the details, it should be said that he is still a little confident, but now when he really wants to start the test, he still has some indescribable nervousness in his heart.

"Duan Yun, you are checking if there are any installation errors on the line. Han Zhong was obviously a little worried at this time, although he was ready to take responsibility, he still remained cautious and cautious.

In fact, in Han Zhong's view, this kind of technical transformation is basically difficult to succeed at one time, according to his understanding, even if some professional engineers catch the knife to carry out this kind of technical improvement, they are all tested and improved, and it takes a long time to complete it repeatedly, and it is almost rare to succeed at one time.

"There shouldn't be any problems. After Duan Yun checked the modified parts and lines again, he said to Han Zhong: "Master, it's time to turn on the machine, you stand far away first." ”

"Wait!" Han Zhong suddenly shouted.

"What's wrong, master?"

"Give me another cigarette. Han Zhong stretched out his hand and said.

Han Zhong rarely smokes in the workshop, but this time his emotions were obviously a little excited.

Duan Yun didn't say a word, took out a cigarette and handed it to Han Zhong, then lit it with a match.

Subsequently, after Duan Yun was ready, he started the lathe.

"Buzz!"

The moment the power is turned on, the spindle begins to rotate rapidly.

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 semi-finished stigma element placed on the angle iron is quickly pushed against the spring chuck in front of the spindle and is fixed, and then the longitudinal knife 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 down in circles, and a rough column head was quickly cut.

"Click!"

The lever pushes the transverse turning tool forward, the machined column head is cut off, the spring chuck is released, and the scrap rolls down into the iron box located under the spring chuck.

Seeing this scene, Duan Yun and Han Zhong's hearts jumped violently.

The lathe was still running automatically, and it was not until all the five raw materials on the feeding rack were processed that the expressions of the master and apprentice began to ease a little.

"Take it and measure the accuracy. Han Zhong said a word to Duan Yun, but then immediately reminded: "Use an iron clamp to pick it up, be careful of burning your hands!"

Hearing this, Duan Yun took out all the finished products from the iron shell placed under the card head and put them on the toolbox next to him.

Han Zhong took out the vernier card from the box, this kind of rough car product doesn't need a micrometer.

After carefully measuring them one by one, Han Zhong took two puffs of cigarette and suddenly a smile appeared on his face.

"No problem, they're all qualified!"

"Then our modification will be considered a success, right?" Duan Yun asked with a smile.

"There shouldn't be a big problem with quality, and we have to see how efficient it is. Han Zhong was also excited at this time, and after glancing at his watch, he said: "There are still two hours to get off work, put all the materials on the angle iron shelf, and I'll see how much I can process in this hour!"

"Hmm. When Duan Yun heard this, he immediately walked to the preparation box of the station, took out the blank inside, and gently placed it on the angle iron shelf where the material was fed.

Subsequently, the machine was started again and a new round of automatic machining procedures began.

One, two, three...... The stigma head finished by the chips kept cutting and rolling off from the junction of the card head, so fast that Han Zhong, who had been a lathe worker all his life, couldn't help but smack his tongue.

Generally speaking, even if it is rough processing a chuck, it is necessary for experienced masters to repeatedly clamp raw materials with chucks, adjust the coaxiality, constantly correct the feed rate and back eating amount during processing, and then judge the cutting force and whether the cutting temperature is in the normal range by the color of the iron filings, etc., which is time-consuming and laborious.

The automation improvement of Duanyun this time sets everything in advance, eliminating a lot of cumbersome steps in manual operation, which undoubtedly greatly improves the processing efficiency of the lathe.

37，38，39......

Han Zhong had been silently reciting the proficiency of the finished product in his heart, and when he looked down at the watch on his wrist that had only passed less than thirty minutes, he already felt a huge shock in his heart.

Nearly forty parts were machined in thirty minutes, which is definitely the fastest in the factory!

You must know that in the past, Han Zhong used this machine tool to process ninety-one parts in eight hours of normal working time at most, and it can be said that it was almost non-stop at that time.

As for normal times, Han Zhong only processes forty or fifty finished products a day.

But now, this automatic lathe almost completed his previous nearly a day's workload in less than half an hour, and the efficiency is far beyond Han Zhong's imagination!

But at this time, Duan Yun was still a little dissatisfied with this automatic modification.

In his opinion, there are still a lot of things that can be improved on this automatic lathe, and if it is changed again, Duan Yun is confident that it can at least double the efficiency!

In fact, if it weren't for the fact that this former Soviet lathe was too old and the spindle speed was slow, Duan Yun would have even more room to play!

For more than an hour, the master and apprentice quietly observed the operation of the machine.

Time flies, the lathe is always running normally, and the time for the shift is getting closer and closer, and through the window, you can even see the figures of the workers who come to work outside.

132，133，134......

Han Zhong's eyes staring at the lathe were already fascinated.

"Shhh

Feeling a sharp pain in his fingers, Han Zhong shook off the cigarette fart that was about to burn out in his hand, and then withdrew his gaze from the lathe.

"Master, are you okay?" Duan Yun on the side saw this and hurriedly asked.

"It's fine. Han Zhong shook his head when he heard this, then turned his head and patted Duan Yun's shoulder, and said with a smile: "Duan Yun, with this machine, the representative of the model workers in our factory this year will be none other than you......
