Return to the exciting era of 1999

Chapter 191 Let You Meet a Real Turner
"Dongfeng Missile faced many problems in the processing of many parts, especially the processing accuracy of the core parts was not up to the requirements! Later, our country held a national technician competition, and the veteran technicians from several military factories in the Northeast came out on top. Then the state gathers these people together!"

"Of course the competition back then was not limited to equipment, but also included welding, casting, and sheet metal forming... Several old technicians from our school had participated in that big competition back then!"

"Later, with the gradual iteration of imported equipment and some changes in factories, these skilled workers gradually spread to all parts of the country! You kid is definitely not simple, and you were able to find one!"

Speaking of that period of history, Li Dongxin is like a treasure, and while Ji Donglai smiled apologetically, he began to be curious about Li Dongxin's identity, especially when the other party's waist was straight.

"Dangdang!"

"Fuck, Ji Donglai, you found a treasure. Let me tell you, just this old mechanic is worth at least a villa, the kind in the core area of ​​Hangzhou!"

When Li Dongxin was shocked, the old mechanic finished sharpening his knives, just when the other party thought the old mechanic would start working.

The other party directly opened the gear box of the machine tool, beckoned the worker to give him the wrench, and then began to replace the gears.Not to mention, most lathe workers in China cannot do this alone.

Today's lathe workers can process parts and components are already very popular. They can really freely match gearboxes according to the requirements of parts, which is rare in the whole country, or it can be said that there are almost none.

Why can the lathe worker be ranked first in the car pliers washing planing and grinding?

Because the old car workers can not only drive, but also repair cars, and even assemble cars.

After using the lathe for a period of time, you can remove the gears and replace them by yourself. Even many new engineers cannot do the free allocation of reduction ratios, let alone small lathe workers.

"Tch, why are your villas so valuable? I won't change eight villas, and I'll tell you, the house I bought specially in the community over there is for them to live in, with good wine and food every day! To tell you the truth, even my own Dad, I didn't even take care of me like this!"

It was the first time for Ji Donglai to see the old mechanic freely assembling lathes, and soon Ji Donglai calmed down, the respect from before was gone, and calmness was replaced by it.

Li Dongxin looked at Ji Donglai, with rare shock in his eyes.

It was the first time Li Dongxin met a young man who paid so much attention to technology before graduation, and he was just a freshman, so he could see that the person the teacher sent for him definitely had something to learn.

"Swish!"

After the gear was replaced, the old mechanic wiped his hands, then began to wipe the guide rail of the machine tool, and dripped a little oil on the lead screw.

"Buzz..."

Start the lathe again, the sound of the machine tool is different.The speed of the vehicle is obviously different from the original one. The old mechanic knocked on the chuck and started to clamp the workpiece after alignment.

After tidying up here, he rubbed the turning knife on the sandpaper again. After everything was done, the other party drove again.

"Buzz..."

"Tsk tsk, he is definitely an expert! I have a few blueprints in the east, you can process them for me, it's not difficult! For the joint parts, add the public back and I'll use them to match other sizes!"

Watching the old mechanic start to slowly push the knife holder forward, Li Dongxin nodded, took out his notebook, and drew a sketch on it, which was a concave circle.

The surface roughness is 42, the dimensional accuracy is three decimal places, and the material is [-]CrMo.

"Three thousand and five one, friendly price!"

"make a deal!"

They are all experts, and there is no haggling and bargaining. Li Dongxin takes the money, Ji Donglai asks Cui Mingyan to come down and enter the account, and then he goes upstairs to draw a picture and place an order. When Ji Donglai comes down again, the old mechanic's The concave circle has already disembarked.

"Master, do we need to dig a hole in the center of this circle? After all, it's not easy here!"

Holding the concave ball in his hand, Li Dongxin inspected it carefully. Although the processing deviation of the center of the ball could not be seen, Li Dongxin was still worried based on his experience.

"No, I've been practicing for decades, and I've been practicing for two years just at the center of the ball! The point contact of the ball knife, now they are called R knife! This knife is made of tungsten steel, the wear is not so serious, it is normal One joint and one knife, you are using it on the balancer!"

The old mechanic lit a cigarette, waved his hand and the little worker went to work on other machine tools.

"How do you know?"

Hearing what the old mechanic said, Li Dongxin's eyes were filled with shock. Recalling the four ball heads under the balancer, it seems that the drawings are kept secret.

"Don't be surprised, center drilling is my second-level standard, because the machine tool you are introducing now is defective and can only be processed to that extent! The drawing has my signature on it, and if there is no accident, you can go back and find the No. [-] box. There are first-level blueprints in there, I guess you still can't process them!"

"The 620 old bed should have been small when we built it back then. Now, there are basically not many people willing to use that bed for fine work, because it requires higher skills for workers!"

"But no matter how sophisticated the CNC machine tool is, no matter how sophisticated the CNC system is, it is a partial replacement of the human brain. At that time, Dalian Machine Tool, BJ Machine Tool and Shenyang Machine Tool, including Anyang Machine Tool, all asked me to drive it! It's a pity that I wasted my money. In terms of cost and time, they haven't caught up with the foreigner's system until now!"

"CNC machine tools are still used to draw dots and connect lines. The denser the points, the better the things you can make. If you don't believe me, you can take a closer look at the things processed by the CNC machine tool. They are all textured. They must be polished and ground later, otherwise they will be easier to use than ordinary machine tools. I'm still struggling, alas, I won't tell you about history, it's all over..."

While speaking, the old master picked up the enamel jar, opened the lid, shook the tea in it and drank a couple of sips, the image of the great man on it was still clearly visible, the surface was only slightly discolored, but the paint did not come off at all.

The words "Glory to the Workers" are presenting an arc around the image, puffing the black smoke in his hand, and the old man's face is full of longing and memories of that era.

"I really didn't expect that I could see our older generation of masters here, let's go out and have a drink..."

"Forget it, we only drink with a few old buddies now, and the rest don't drink! You can drink with our boss. He is old and talking about his age. The next shift is another colleague of ours. Excuse me!"

Shaking the tea mug in his hand at Li Dongxin, and then saying hello to Ji Donglai, the master turned around and left without the slightest delay.

Ji Donglai hastily waved at the opponent, not intending to stop him at all.

Don't work overtime, don't go to work early, go to work on time, don't procrastinate when doing work, and don't do anything that shouldn't be done, Ji Donglai is used to it.
