The successful modification of the gear grinding machine is another stage victory for Duan Yun, which also means that Duan Yun has completed the most critical step in the finishing of automobile gears.

With this gear grinding machine, Duanyun Factory is a level higher than the gear processing of the main factory, and has the level of precision in processing automobile gears.

However, if you want to make a variety of index parameters qualified automotive gearbox, Duan Yun still has a lot of technical things to solve, one is the introduction of gear steel, the toughness and strength used in the agricultural machinery gear of the main factory just now is used to make the automotive gearbox gear index is unqualified, Duan Yun also needs to introduce gear special steel from other channels.

There is also the problem of heat treatment of gears and the surface strength of gears, which is a key technology related to the durability of gears.

As for the strengthening of the surface hardness of the gear, Duan Yun needed to introduce Cheng Qingyan's powerful shot peening machine.

In fact, Cheng Qingyan's shot blasting machine was still Duan Yun to help complete the final improvement work, and Duan Yun could also complete the assembly himself, but after all, Cheng Qingyan also paid a lot of effort and wisdom, so Duan Yun still decided to invite Cheng Qingyan into the factory to assist in the installation of the equipment, which can be regarded as a kind of respect and affirmation for her, and it can also make her gain some sense of achievement.

In addition to the technical problems of these indicators, Duan Yun also needs to solve the problems of product testing, quality control of mass production, and cost compression, which need to be improved and solved by Duan Yun little by little.

All in all, the half-year deadline set by the head factory for Duan Yun is not sufficient, and Duan Yun has a lot of things to solve.

Seeing that it was time to get off work, Duan Yun immediately left the workshop, ready to change clothes and leave the factory.

In addition, Duan Yun has an important matter to deal with tonight.

Not long after Duan Yun left the office building, Jiang Jianhua also closed the office door and left work with his leather bag.

It took a whole afternoon for Jiang Jianhua to write a report material, which listed the 'three crimes' after Duan Yun became the general manager of the labor service company, which roughly means that since Duan Yun became the manager, he was stubborn and self-serving, detached from the organization of the masses, abused his power and directly fired the workers in the factory without going through the consultation of the factory congress, was unorganized and undisciplined, hired second-rate hooligans in society into the factory security department, threatened and intimidated the factory workers, and created panic.

Jiang Jianhua has been the secretary of the labor service company for three years, and his eloquence and pen are naturally his strengths. The cold-blooded' arbitrary style of description is very detailed, and the use of a large number of sensational and critical rhetorical sentences has implicitly given Duan Yun's image a sense of immediacy of the evil landlords and old wealth of the old society.

Jiang Jianhua plans to hand it over to the party branch of the main factory tomorrow morning, and if the main factory doesn't care about it, he plans to hand over this report material to the party committee department at a higher level.

At this point, Jiang Jianhua was actually planning to tear his face with Duan Yun, because he had already seen that Duan Yun had gradually gotten rid of his overhead now, and his control over the factory was getting stronger and stronger.

With his purse in hand, Jiang Jianhua just walked to the door and felt that something seemed to be wrong.

I saw that Qin Shengli was standing at the gate of the factory at this time, and Jiang Jianhua, who was watching, smiled at him after passing by.

Jiang Jianhua felt that Qin Shengli's smile seemed to be a little weird, but when he shifted his gaze to the gate of the factory, he found that there were several young men in military coats squatting there, and their eyes were all looking straight at him, and their faces were also smiling.

Seeing this, Jiang Jianhua immediately retracted his gaze, now the people in the factory security department were all pulled over by Duan Yun, and Chen Daqiang and his group were cleaned up by this gang before, if it wasn't Duan Yun's arrangement, Jiang Jianhua would definitely not believe it.

After walking quickly to the carport, Jiang Jianhua opened the lock and just wanted to leave, but found that the wheels were clicking on the ground, squatting down and taking a look, he found that the two tires were deflated, and after pulling out the air hole with his hand, he found that the valve core inside had been pulled out.

"Who did it!?" Jiang Jianhua was angry at this time, and couldn't help shouting.

But hearing Jiang Jianhua's roar, Qin Shengli and the others at the gate turned their heads to the side one after another, and they didn't hear it, and they were still talking and laughing with each other.

Seeing this scene, Jiang Jianhua understood that this incident was done by Qin Shengli's gang of people from the Security Department, but now there is no evidence, Jiang Jianhua can only scold a few words angrily, and there is no way at all.

In desperation, Jiang Jianhua had to push the car out of the factory gate, and when he saw Jiang Jianhua walking out, the young men in military coats squatting at the door also stood up and followed him.

Seeing that the sky was darkening, and there were six or seven young people with strange expressions behind him, Jiang Jianhua suddenly felt his heart beating wildly, his back was cold, and he couldn't help but speed up his steps.

In the early years, very rare homicides, rapes, and robberies have been frequently reported since last year, so that many school girls and factory workers do not dare to go out alone at night, and some girls will even be called by the teacher to criticize them the next day if they come home from school alone.

Jiang Jianhua remembered what Duan Yun said yesterday, and there was obviously a bit of a threatening tone in his tone, and in the morning, he saw Duan Yun and Qin Shengli and others talking to defend Kemen**, during which because Jiang Jianhua ignored Duan Yun's greetings, Qin Shengli and others also scolded themselves a few words.

Thinking about it again, even Chen Daqiang and his group, who had always walked sideways in the factory area, were easily cleaned up by the group of security guards brought by Duan Yun, and Jiang Jianhua was even more afraid in his heart.

After walking dozens of meters from the factory's cart, Jiang Jianhua suddenly saw a car parked at the intersection in front of him, which was Duan Yun's 212 jeep.

Jiang Jianhua's eyelids jumped violently when he saw this, and he wanted to walk away from the other side as he pushed the car.

At this time, the headlights of the car suddenly turned on, Jiang Jianhua felt a dazzling sound, and subconsciously blocked his eyes with his hand.

The next moment, the car door opened, Duan Yun walked out of the driver's seat, a cigarette in his mouth flickered on and off, and said to Jiang Jianhua:

"Secretary Jiang, I've been waiting for you for a long time......"
