Like yesterday, Duan Yun first processed a few parts by hand at the beginning, and at about one o'clock, when some employees went to the boiler room one after another to pick up lunch boxes for supper, Duan Yun took out the servo motor and other parts from the box and quickly installed them on the lathe.

After all the installations are completed, the lathe enters the automatic machining stage again with the humming sound of the spindle starting.

In fact, today, the modification of the lathe is already a novelty for Duan Yun, and after standing on the edge of the lathe and counting the finished products for a while, he feels a little boring.

Duan Yun himself is not a person who can be idle, in his previous life, when he was working in the locomotive factory, he didn't sit in the office, and he liked to walk around the workshop.

Until four o'clock in the morning, Duan Yun had already processed more than 300 column heads, and seeing that the sound of the machine in the workshop was gradually decreasing, he simply turned off the machine temporarily and walked around the workshop.

When he walked to the other end of the plant, Duan Yun's eyes were immediately attracted by an X5032 vertical milling machine.

The reason why Duan Yun was attracted to this milling machine was also very simple, because when he worked in a machine tool factory in his previous life, there was also a machine in the workshop that was exactly the same as this milling machine.

So when Duan Yun saw this milling machine, he really had a feeling of being in a different world.

Walking forward, when Duan Yun first looked at the parts processed by this milling machine, a man's voice suddenly came from behind:

"What for!?"

"Uh. Hearing this, Duan Yun turned his head and found a tall man standing behind him.

This man looked similar to Duan Yun's age, his skin was slightly dark, his hair was hot and he had big sideburns, and his eyes were a little gloomy when he looked at Duan Yun.

"Ah, I'm just here to take a look. Duan Yun hurriedly said with a smile.

"Is it you?" The hot-haired man was slightly stunned after seeing Duan Yun's appearance, and then asked, "Why are you running away from my workstation if you have nothing to do?"

"I'll just look at this milling machine. ”

"What's so nice about this broken machine?" the scalding man glared at Duan Yun, and then scolded, "Get out!!"

"Brother, I'll take a few looks and leave. Duan Yun obviously didn't want to leave.

"Who is TM with your brother? are you TM compatible?" The hot man seemed to be very unkind to Duan Yun, and saw that Duan Yun didn't want to leave, so he rolled up his sleeves.

"Big brother smoking!" Seeing the hot-headed man rushing in front of him quickly, Duan Yun unhurriedly took out a large front door from his pocket.

"Hmm. The hot man was stunned for a moment when he saw Duan Yun take out a cigarette, and when he saw the brand of the cigarette, he reached out and took the cigarette and put it on his ear, and said to Duan Yun: "Give you time for a cigarette, and when I come back later, I don't want to see you at the workstation, understand?"

After the hot man finished speaking, he turned around and left the workstation and walked towards the door of the workshop.

Duan Yun saw him leave, and continued to observe the milling machine.

In the box next to it are the blanks of the gears, and on the other side are the finished products that have been processed.

Like the single hydraulic pillar of Duanyun machining, the gears of agricultural machinery gearboxes are also the fist products of the factory.

However, the gears at the level of agricultural machinery gearbox, whether in terms of accuracy or other indicators, are not much different from the gears processed by Duan Yun in the locomotive factory with CNC lathes in his previous life for diesel locomotives.

Generally speaking, the accuracy of automobile gearboxes and engine gears in later generations can reach level five, while the main product of Red Star Gear Factory is now agricultural machinery gearbox gears can only reach level six or seven at the highest.

The X5032 vertical milling machine in front of Duan Yun is a good machine tool in China at present, but it can only use the shaving process to process agricultural machine-level gears, if you want to process gears with an accuracy of more than five levels, this is a level that the shaving process cannot reach, so it also needs more advanced gear grinding technology, as well as advanced equipment such as special gear grinding machines and gear testing centers.

In addition, in addition to the precision of this agricultural machinery gear is not high, heat treatment processing can only be regarded as a low-end level, before Duan Yun and the master in the various workshops to turn, Duan Yun in the heat treatment workshop only saw a heat treatment furnace heat treatment processing process still uses the parameters of SL twenty or thirty years ago, and did not see the gear factory commonly used in the later generations of gear surface hard processing equipment such as strong shot peening.

With the current level of domestic machine tools and related equipment, it is very difficult to achieve the accuracy of the later generations of automobile-level gear processing, unless there is imported professional equipment, but in this year, this high-end imported machine tool equipment is very few, and it is also preferentially used in the military sector.

In Duan Yun's view, if a few foreign advanced gear grinding equipment can be introduced in this year, with the current domestic cheap labor and cost advantages, the export of commercial vehicle gears is definitely a lucrative business, which can earn a lot of foreign exchange income for the country, but limited to the current national conditions and policies and related software and hardware supporting facilities are not complete, Duan Yun's idea is basically not possible to be implemented.

However, although Duan Yun does not have the ability to change an industry now, it is still possible to improve a production process in the workshop at present.

At present, the factory uses a milling machine to process gears, and basically relies on workers to manually correct the milling machine and adjust the indexing head to complete the processing, and the efficiency is very low.

Duan Yun, on the other hand, can modify it into an automatic gear hobbing machine through the information he has seen in his previous life, and like the lathe that was modified before, it needs to add some gears and components, and the efficiency can be increased by at least several times.

Since Duan Yun entered the first workshop, he seems to have a feeling of being at home like a fish in water, and he is a professional counterpart, and there is a lot of room for display.

It's just that Duan Yun still needs to wait for the opportunity at the moment, in the case that the connections in the factory are not hard, he has no chance to display his talents, and many things need to be done step by step.

After taking a look around the milling machine, Duan Yun left only when he saw the big sideburns returning quickly from the door of the workshop.

It wasn't that he was afraid of the black-faced young man, he just felt that there was no need to have any conflict with that kind of person.

After returning to his station, Duan Yun changed the turning tool and started the lathe again.

Until he got off work at about seven o'clock in the morning, Duan Yun had processed a total of more than 700 stigmas that night, which was basically the same as yesterday, and he should have earned more than 50 yuan in bonuses.

Turning off the machine and packing up the workstation, Duan Yun used a small cart to push the boxes of workpieces into the warehouse, and then changed his clothes and left work.

Not long after Duan Yun left, Tian Feng, who was on the morning shift, came to the workshop.

As a technician in a workshop, Tian Feng not only routinely distributes the workpiece drawings to be processed to the team every day, but also needs to take into account the quality inspection of the finished products produced by the workers every day.
