"Okay, I'll arrange it when I get back. Wang Qiang nodded in response when he heard this.

"Duan Yun, you have to come on this time, you work hard tonight, test the machine overnight, and tomorrow morning I will arrange for the main leaders of the whole factory to come here for acceptance." Qin Gang patted Duan Yun on the shoulder, and said, "This is a major matter related to your future, but you must not make any mistakes......

Qin Gang is a scheming person, he arranged for Duan Yun to work overtime tonight for testing, in fact, it left Duan Yun enough time and opportunity to correct mistakes, after all, there are few people on the night shift, once there is a problem with the machine, the matter will not spread quickly, and the workers who cooperate with his maintenance team will have time to quickly repair it, if it cannot be repaired, as long as the machine is not damaged, then Qin Gang can at most give Duan Yun a few more days, leaving enough room for maneuver.

"Thank you, Director Qin!" Duan Yun could naturally hear Qin Gang's intention to make such an arrangement, so he thanked him repeatedly.

"You're busy. After Qin Gang finished speaking, he turned around and left.

"Duan Yun, come on!" Cheng Qingyan, who came with the factory director at this time, also smiled and encouraged Duan Yun, and then left with everyone.

Cheng Qingyan has also been very busy in the past two days, her powerful shot peening machine has been assembled in the heat treatment workshop, and she will lead Qin Gang over to take a look this morning, otherwise, she will definitely chat a few more words here with Duan Yun.

With the departure of the factory director and Cheng Qingyan, Duan Yun can finally concentrate on modifying the machine tool.

At this time, several masters of the maintenance class also came over after the morning shift, but Duan Yun did not arrange for them to install the line, but settled them to make a shell for the modified gear hobbing machine.

The reason why he was not allowed to install the line was mainly because Duan Yun still needed to keep some technical secrets, so that only he could repair this machine in the future, so that Duan Yun could avoid crossing the river and demolishing the bridge in the factory in the future, so the back hand that should be left must be kept!

Duan Yun installed it very carefully, especially when connecting the control circuit board, he was even more careful, until the electronic control board was fixed, and then he breathed a sigh of relief.

Next, Duan Yun and several masters of the maintenance class made the shell of the machine, cut the iron sheet, welded it, polished it after installation, and were busy from morning to noon, after eating in the factory canteen, and then worked until five o'clock in the afternoon, and all the work was completed.

"Xiao Duan, how's it going?" asked Wang Qiang, the director of the workshop, at this time.

"It's ready to be tested. As Duan Yun spoke, he picked up the tooth embryo next to the machine, put it in the dumping rack, and then looked at the processing drawing parameters of this batch of gears, turned around and pressed a few buttons on the CNC board, and finally pressed the start button.

"Buzz!"

The moment the power is turned on, the main motor makes a humming sound.

After the cutter head comes into contact with the workpiece, the blue iron filings slowly roll off under the coolant.

"This thing seems pretty powerful. Wang Qiang, who was on the side, said in surprise when he saw this scene.

Wang Qiang is the first time to see such a way of processing gears, although it is similar to the processing principle of the milling machine, but the speed is obviously much more efficient.

"Bang dang!" A few minutes later, after the first gear was processed, Duan Yun immediately stepped forward to check it with the vernier card.

Seeing that the accuracy of the detection was qualified, Duan Yun breathed a sigh of relief.

"Congratulations!" Seeing that the gear was successfully processed, Wang Qiang immediately stepped forward to congratulate Duan Yun, then glanced at his watch and said, "It's almost time now, let's get off work first." ”

"It's not done yet. Duan Yun frowned and said to Wang Qiang, "Director Wang, can you arrange for someone to watch the machine at night?"

"That's fine. Wang Qiang responded, and then called the team leader of an afternoon shift, and after settling down, the team leader soon called a young worker.

Next, Duan Yun explained a few words to the young worker, taught him how to control the gear hobbing machine, and observed the operation of the machine at the station until half past six, then left the young worker on duty and turned around and went home......

......

At eight o'clock the next morning, Qin Gang, Zhao Dongsheng, Cheng Changlin and other leaders of the party committee of several factories came to a workshop together.

The leaders of Duan Yun's modification of the gear hobbing machine were already known, and they all got the notice of the acceptance of the technical transformation equipment in the workshop yesterday, so after everyone went to work in the morning, under the leadership of Qin Gang, they came to the first workshop.

However, when several factory leaders came to the milling machine that Duan Yun modified yesterday, they found that there was not even a figure on the station!

"What about Duan Yun, which of you saw him?" asked Secretary Zhao Dongsheng to the people around him.

"I didn't find anyone else in the technical department just now, and I thought this kid had already arrived in the workshop. Cheng Changlin said.

"What time is it...... Qin Gang glanced at his watch, a flash of displeasure flashed on his face, and then he said, "Let's wait first, it is estimated that Duan Yun will come over soon." ”

When the people heard this, they were silent.

Three-minute ...... Five minutes...... When ten minutes passed, several leaders present frowned on their faces.

No one thought that they would accept the equipment as soon as they got to work this morning, but Duan Yun hadn't come to work until now, so the leaders stood and waited for so long!

Although Duan Yun is now in the factory in full swing, he is a college student and has just gone abroad, and he is favored by the director of the municipal bureau, but it is obviously too much to help the leaders of the factory hang here for a long time!

If it weren't for the factory director and secretary to settle everyone and wait patiently, I'm afraid that some leaders would have been furious, and at this time, Qin Gang's face began to show a trace of anger......

"I knew that this kid's technical transformation plan was unreliable!" At this time, Cheng Changlin snorted coldly, and then said: "He actually wants to convert the milling machine into a CNC gear hobbing machine, which is simply whimsical!

"Dad...... Don't talk about it......" Cheng Qingyan on the side said with a frown when she heard this.

"Wang Qiang, have you seen Duan Yun?" At this time, seeing Wang Qiang, who had just finished the morning shift meeting and assigned tasks, Zhao Dongsheng asked after calling him over.

"Duan Yun, didn't he come?" Wang Qiang was stunned for a moment when he heard this, and saw that the faces of several leaders present were not good-looking, so he explained: "Yesterday Duan Yun said that he wanted to find someone to watch the machine, so I arranged a young worker for him, and then I went home from work...... I saw the kid watching the machine just now, he was changing his clothes, and I called him over!"

"Go!" Zhao Dongsheng said with a wave of his hand.

More than ten minutes later, Wang Qiang led a tall young worker to walk over quickly.

"The machine that Duan Yun showed you yesterday, did he say anything?" Qin Gang asked the young worker.

"He just taught me how to operate this machine...... In fact, it is just a matter of pressing the button a few times, and then after a while, the tooth germ is placed neatly on the shelf. The young worker pointed to the digital control panel installed on the console.

"It's that simple?" Qin Gang said after glancing at the digital control board.

"Hmm. The tall young worker replied and said. "He told me to just shut down the gears after I finished machining them. ”

"This is the drawing of the gear processed by this machine last night?" At this time, after Cheng Changlin saw the drawings on the cabinet, he picked it up and looked at it, and asked the young worker.

"Hmm. The tall young worker nodded.

"How much was processed in one night?" Qin Gang glanced at the preparation box, turned his head to Wang Qiang and said, "I remember you said that there are a total of three hundred tooth embryos, why is there not a single one in this box?"

"It was all processed last night, and I was sent to the warehouse in the morning. The tall young worker said.

"What!?"

As soon as the tall young worker's voice fell, several leaders on the scene were taken aback.

Although some of the leaders present were not from technical backgrounds, one machine processed 300 gears in one night, which obviously sounds a bit exaggerated!

"Didn't you say that it would take several workers a week to finish those three hundred gears? How could this machine be finished in one night?" After a while, Qin Gang turned to Wang Qiang and asked.

"I don't know...... But our factory has already made several orders for gears of this specification, and a skilled worker can process up to a dozen ...... a day" Wang Qiang paused, and then said: "But yesterday afternoon, I saw that this machine modified by Duan Yun is really easy to use, and the processing speed is quite fast......"

"Impossible, this is absolutely impossible!" At this time, Cheng Changlin took a careful look at the parameters on the drawing, showed an unbelievable look on his face, and said to the young worker: "Where is the finished product processed last night, you take me over to take a look, I want to check it!"
