"Dongfeng Missile faced many problems when processing many parts back then, especially the processing accuracy of core components was always 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, and then the state gathered these people!"

"Of course, the competition was not limited to equipment, but also welding, casting, forming sheet metal...... A few of our school's veteran mechanics participated in that big competition back then!"

"Later, with the gradual iteration of imported equipment and the changes of some factories, these skilled workers gradually spread to all parts of the country! You're definitely not simple, you can even get one!"

Speaking of that period of history, Li Dongzin is like a treasure, Ji Donglai smiled and became curious about Li Dongzin's identity at the same time, especially the other party's waist was straight.

"Dangdang!"

", Ji Donglai, you have found a treasure, let me tell you, this old mechanic is worth at least one villa, the kind in the core area of Hangzhou!"

When Li Dongzin was shocked, the old mechanic's knife was finished, just when the other party thought that the old technician would start working.

The other party directly opened the gearbox of the machine tool, beckoned the worker to give him the wrench, and then began to replace the gear. Not to mention, just this hand, the vast majority of domestic lathe workers can not do it.

At present, the lathe can process the parts out of the incense, and can really freely match the gearbox according to the requirements of the parts, which is rare in the country, or it can be said that there is almost none.

Why can the lathe be ranked in the boss position?

Because the old lathe worker can not only drive, but also repair the car, and even assemble the car. qδ

After using the lathe for a period of time, you can remove the gears and replace them, and even many new engineers can't do the free rationing reduction ratio, let alone small lathes.

"Cut, why is your villa so valuable? I won't change the eight villas to tell you, I bought a house in the community over there and gave them a place to live, and good wine and food are provided every day! To tell you the truth, I didn't even serve my own father like this!"

The matter of the old mechanic freely assembling the lathe, Ji Donglai also saw it for the first time, and soon Ji Donglai calmed down, and his face did not have the respect just now, but was calm.

Li Dongzin looked at Ji Donglai, and there was a rare shock in his eyes.

A young man attaches so much importance to technology before graduating, Li Dongzin is still the first time to see him, and the other party has just been a freshman, so he can see that the person sent by the teacher to him definitely has something, and he can really understand it.

"Whew!"

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

"Buzzing ......"

Start the lathe again, and the sound of the machine is different. The speed of the car was obviously different from the original, and the old mechanic knocked on the chuck, and after the alignment was completed, he began to clamp the workpiece.

After cleaning up here, he rubbed the car knife on the sandpaper again, and everything was done, and the other party drove again.

"Buzzing ......"

"Tsk, you're definitely a connoisseur! I have a few drawings from the east, you can process it for me, it's not difficult! For the joints, I'll take it back to other sizes!"

Looking at the old mechanic who began to slowly push forward the knife holder, Li Dongzin nodded, took out his notebook, and drew a sketch on it, which was a concave circle.

The surface roughness is 0.4, the dimensional accuracy is 3 decimal places, and the material is 42CrMo.

"Three thousand and fifty-one, friendly price!"

"Deal!"

are all connoisseurs, there is no bargaining for bargaining, Li Dongzin took the money over there, Ji Donglai beckoned Cui Mingyan to come down and enter the account, and then went upstairs to draw a picture and place an order, and when Ji Donglai came down again, the concave circle in the old technician's hand had already gotten off the plane.

"Master, do you need to dig a hole in the center of this circle? It's hard to get it here, after all!"

Holding the concave circle in his hand, Li Dongzin carefully checked it, although he couldn't see the processing deviation of the ball center, but with experience, Li Dongzin was still worried.

"No, I'll practice

It's been decades, and I've been practicing for two years just in the center of the ball! Ball knives point contact, now they are called R knives! This knife is made of tungsten steel, the wear is not so serious, it is normally a joint knife, you are using it on the balancer!"

The old mechanic lit a cigarette and waved his hand to work on other machines.

"How do you know?"

Hearing the old mechanic say this, Li Dongzin's eyes were shocked, thinking back to the four ball heads under the balancer, it seemed that the drawings were confidential.

"No surprise, center drilling is my second-level standard, because the machine you're bringing in now is defective and can only be machined to that extent! The drawings have my signature on them, and if nothing else, you can go back and find Box No. 1, which is a first-class drawing, and I guess you can't process it!"

"The old bed of 620 was not big when we built the machine, and now there are basically not many people who are willing to use that bed to do fine work, because the skills of the workers are higher!"

"But no matter how precise the CNC machine tool, no matter how precise the CNC system is, it is a partial replacement of the human brain, Dalian machine tool, BJ machine tool and Shenyang machine tool, including Anyang machine tool have all asked me to pass the supervision! It's just a pity that I wasted my prison book and time, and they haven't caught up with the foreigner's system until now!"

"CNC machine tools to put it bluntly or trace the dots, the denser the points, the better the things to do, I don't believe you can take a closer look at the things processed by CNC machine tools, all with lines, and they must be polished and ground in the later stage, otherwise it will be more laborious to use than ordinary machine tools, alas, I don't put history with you, it's ......all over."

While speaking, the master picked up the enamel jar, opened the lid, shook the tea inside and drank two sips, the image of the great man on it was still clearly visible, and there was only a slight discoloration on the surface, but the paint did not fall off at all.

The words "Workers' Glory" are presented in an arc around the image, and the old man's face is full of longing and memories of that era.

"I really didn't expect that I could still meet our older generation of masters here, let's go out and have some drinks......

"Forget it, we only drink with a few old buddies now, and the rest don't drink! You drink with our boss, people are getting old and old, and the next shift is another colleague of ours, who is out of company!"

shook the teapot in his hand at Li Dongzin, and then said hello to Ji Donglai, the old master turned around and left in a dashing manner, without the slightest drag.

Ji Donglai hurriedly waved his hand to the other party, and he didn't mean to stop it at all.

Don't work overtime, don't work in the morning, step on the point to go to work, there is no procrastination when doing work, and don't do anything that shouldn't be done, Ji Donglai is used to it.
