A nation's industrial development begins with junior engineers.

By the time Jiang Xia and Master Qin finished setting up the fixtures, it was already time to leave work.

Worried about his master's injury, Jiang Xia handed the clamps and instructions to Master Ning and left in a hurry.

Master Ning lives in Zhongguancun, and going back and forth would take too much time, so he simply applied for the factory's dormitory.

After receiving the jig from Jiangxia, I didn't pay much attention to it at first. I planned to work an extra night shift to finish processing the gear blanks so I could take a break tomorrow.

When he washed his lunchbox and returned to the workshop, Xia Fengnian, who was operating the C620, was already standing by the lathe and starting to repair the machine.

After exchanging greetings, Master Ning put down his lunchbox, checked the machine, and then started the lathe by selecting the blank material.

The lathe light came on, its bright beam illuminating Master Ning's meticulous face. The rod-shaped blank was being cut into small round discs.

"Kakakaka!!"

A grinding sound came from the lathe gearbox, and then the whole lathe trembled as the high-speed rotating blank collided violently with the cutting tool.

Master Ning calmly pressed the power button. Looking at the twisted blank and the blade, he sighed helplessly.

I probably won't be able to take a day off tomorrow.

The loud crash caught Xia Fengnian's attention. He stopped the lathe and shouted at Master Ning, "What happened?"

"It's nothing! It's an old problem, the car just shook a little. Help me find the balance again in a bit!"

"Damn! The gears on that old oxcart broke again? Damn it, I told the repair team to use better materials to make the gears, but they never listen! They don't know how troublesome it is to rebalance them."

Master Ning shook his head: "We used good materials. You've forgotten again, we've now merged into a steel rolling mill! The gears here were made by the old machinery factory back then."

Xia Fengnian pulled his head back, his series of complaints drowned out by the rumbling of the lathe.

Master Ning glanced enviously at Xia Fengnian's lathe, wondering if Factory Director Yang could ask for a few more. If he did, he wouldn't have to take care of this old machine anymore.

Open the lid to allow the parts inside to cool down.

Looking at the chipped area again, hmm, the same old formula, still the same old story.

Hopefully, the new gears made by the steel rolling mill will last a while longer.

Remembering the fixture Jiang Xia had given him, he took out the instruction manual while the machine tool was cooling down. Hmm? This seems interesting.

Trusting engineer Xiao Jiang, Master Ning replaced the old chuck with this hollow three-jaw chuck.

Then I took the damaged knife off the knife rack and placed a pencil on it.

Rotate the spindle by hand and watch as the pencil draws a straight line on the workpiece.

That's right, the master chef's skills are superb, the consistency is amazing!

Seeing that the gearbox temperature had dropped, they called Xia Fengnian over, and the two of them started replacing the gears inside the gearbox together.

It's fortunate that it's an older machine; a C620 like that would never be something they could repair themselves. If it broke down, they'd have to report it to the repair department, which would then report it to the technical department, and the technical department would contact the manufacturer for repairs. It was incredibly troublesome.

After all, there are no 24-hour service hotlines nowadays.

After installing the gears, I used a balance ruler to level the car body. An hour had passed by the time I finished.

"Tsk, Master Ning, next time you should just call the repair department. It's not worth getting all sweaty and stuffy!"

Master Ning handed him a cigarette: "Hey, there aren't many people in the maintenance department of this steel rolling mill who know how to fix our machine tools. After all, others are playing with rolling mills, so we'll do whatever we can to fix them."

"Don't forget how Director Yang treated us. I didn't even expect to get my wages back from the first few months. But he made up for it all. What a kind gesture!"

Xia Fengnian exhaled a beautiful smoke ring, a smug smile spreading across his face: "Brother Ning, do you still remember those old guys from the old machine factory's repair department?"

"Hmm, those guys who run the car factories?"

"Hehe, they're green with envy when they heard we got their back wages. The car factory promised to pay them, but there's still no sign of it!"

Master Ning clicked his tongue, unsure of what to say.

"Hey? Brother Ning, is this the fixture that Engineer Jiang gave you? It looks a bit strange."

"Hmm, the manual says it can push the material without stopping the machine, but it needs some settings. Let me see, one revolution is one centimeter, so for three centimeters, it needs to rotate three times."

"It's all set up, let's try it out!"

Master Ning started the lathe and immediately began feeding as the spindle rotated.

When the newly installed cutting tool came into contact with the blank, the iron filings curled up and clumped together.

2.7 cm

It's 2.8 centimeters!

Just as Master Ning was about to stop the car, the entire billet moved forward a distance along the central axis.

Master Ning opened his mouth, "It's adjusted already?"

This section was quickly completed as well.

"Click"

The blank material moved forward another three centimeters.

Master Ning continued operating, and the workpiece was completed!

Xia Fengnian's mouth dropped open: "Holy crap! Automatic feed? Achieved through a fixture? What kind of operation is this?!"

Master Ning stopped the car, removed the workpiece, and inspected it.

Xia Fengnian rushed to the control room: "Brother Ning, bring me a piece of material, I want to try it too."

Master Ning waved his hand, indicating that he could do as he pleased.

He carefully measured the workpiece in his hand using the micrometer left behind by Jiangxia.

Following Master Ning's example, Xia Fengnian first tightened the screwdriver on the clamp three times, and then drove the car!

"Hey, hey, they're out!"

"Great!!! It's out again."

"Finished! Master Ning, how long did it take?"

"Fifteen minutes!"

"Wow, it's even faster than using a 620! It's just that I have to tighten it several times each time. If only I could tighten it once and then not have to worry about it anymore, that would be so great!"

Master Ning chuckled and scolded a few times, but he was already very satisfied.

It seems that the hour lost can be made up for quickly.

……

Li Changfu's home.

Jiang Xia applied a thick layer of badger oil to the old man's hands.

"Master, I'm not trying to be mean, but you're a grown man, don't you know how to do emergency burn treatment? You just rinsed it with cold water after you got burned."

"Look! It's all blistered!"

The old man's burns were not as minor as others made them out to be; a row of blisters appeared on the entire outer side of his left forearm!

The old man winced in pain, but still stubbornly insisted, "A mere burn? I wasn't afraid of the steel mills in Workshop 3 back in the day!"

"A red-hot steel bar shot up 3 meters high and just grazed past me. Was I scared?"

The teacher's wife rolled her eyes at Li Changfu, annoyed: "You weren't afraid, but I wonder whose legs were shaking like noodles those few days."

Li Changfu didn't dare to reply, but instead asked Jiang Xia, "How's the engine assembly going?"

"It's been initially resolved. I divided them into groups based on the situation. Then I stipulated that the parts between the groups are not interchangeable."

"We assembled a few units on site, and they seem to be doing well so far."

Jiang Xia then explained her thoughts to Li Changfu in detail.

Li Changfu nodded repeatedly, and the pain in his arm seemed to have subsided.

"By the way, what meeting did you rush off to? The Ministry of Chemical Industry seems to be quite far from us!"

At this point, Li Changfu raised his eyebrows: "Hey, there's so much machinery in chemical engineering, how come it's so far removed from ours? Those guys who bury themselves in the lab are experts at experiments, but when it comes to machinery, they're the best."

Jiang Xia was speechless when he saw Li Changfu's little finger.

Why are all the people around me getting so arrogant lately?
