Manufacturing Empire in the Valley

Chapter 64 A university professor comparable to an eighth-level fitter
Jiang Ronghua didn't understand these situations, and he was both angry and funny: It seems that Fang Gong really regards my place as a training ground for training apprentices. What should I do if the construction period is delayed because of this!
Fang Dongping seemed to see Jiang Ronghua's thoughts, he smiled and said: "Boss Jiang, don't worry, since I've come, your problem will definitely be solved, and your construction period will not be delayed."

Jiang Ronghua said with a sneer, "That's good... that's good..."

After the test machine, Niu Xiaoqiang turned off the power of the planer, turned his head to Fang Dongping and said: "Master, after my careful observation, the vise is still very firm and there is no looseness. I think the problem should be on the cutter head. As for what the problem is, we need to disassemble the machine to have a look.”

Fang Dongping hummed: "You haven't seen a planer before, this time master will disassemble it by hand, just watch it from the sidelines."

Jiang Ronghua hurriedly stopped Fang Dongping: "Let me do it, you are getting old, just give me some guidance."

Fang Dongping didn't refuse: "Okay, I'll leave it to Boss Jiang."

Jiang Ronghua took out a wrench from the toolbox, and quickly removed the outer cover, exposing the internal structure of the planer. He gently placed the cover on the ground, "I have checked it many times, but I can't find it." Where exactly is the crux of the problem.”

Niu Xiaoqiang immediately came to him and took a closer look. After a short look, he pointed to a transmission gear and said, "Uncle Jiang, the quality of this gear is relatively new, and it is a little different from other gears. Did you just replace it recently?" of?"

Jiang Ronghua nodded: "The original gear was severely worn out, so I bought a new one to replace it, and it has been used for less than three months, far from exceeding the service life, so the problem should not lie in this gear. "

When Niu Xiaoqiang heard this, he asked back: "Uncle Jiang, did this planer have any quality problems before the gear was replaced?"

Jiang Ronghua shook his head: "That's not true."

Niu Xiaoqiang turned his head to look at Fang Dongping: "My master once said that no matter what kind of machinery, as long as the parts are replaced, it needs to go through a running-in period. It doesn't mean that the replaced parts will not cause problems. How about we take this gear out and check it?"

Of course Jiang Ronghua knew the concept of the running-in period, but there was no problem after changing the gear, which made him have no doubts about the quality of the new gear.If it is really a problem of the running-in period, the problem should have appeared long ago, how can we wait until three months later?
At this moment, after hearing Niu Xiaoqiang's proposal, Jiang Ronghua didn't want to agree, because he thought it was a waste of time.But due to Fang Dongping's presence, he had to give this face, so he could only nod at the moment: "That's fine, I'll take it apart."

In this era, a fitter basically needs to know some maintenance techniques.If a worker who turns on a machine tool does not even understand maintenance techniques, he will be ashamed to say hello to his fellow workers when he goes out.

Jiang Ronghua used to be a fitter for nearly 20 years, and his maintenance skills are still very good. He disassembled the gear very skillfully. The whole process took less than 30 seconds, which is quite amazing.

"Master Niu, what tool do you need to use for inspection?" Jiang Ronghua asked as he put the gear on the workbench next to the planer.

Niu Xiaoqiang reached out and picked up the level ruler: "This is enough."

While speaking, he picked up a rag, wiped off the oil on the gears, and then put the level on the workbench to confirm that the readings were normal, and then put the level on the gears.

After just one glance, Niu Xiaoqiang discovered the clue: "Uncle Jiang, I put the ruler on the workbench just now, and the measurement results showed that the workbench was absolutely level, but when I put the ruler on the horizontal surface of the gear, the readings But there was a deviation of plus or minus two degrees, if nothing else, the gear should have been slightly deformed."

Jiang Ronghua had been watching from the sidelines. Before Niu Xiaoqiang could tell the result, he had already seen clearly.Hearing Erlu's words, he couldn't help but gritted his teeth and said, "Gaoqiao, you bastard! How dare you sell me fake and shoddy products!"

Fang Dongping was very satisfied with Niu Xiaoqiang's performance. He first gave Niu Xiaoqiang an approving look, and then suggested to Jiang Ronghua: "Boss Jiang, if you have a spare gear here, just let it go. Let’s talk about it later.”

Jiang Ronghua nodded with a gloomy face: "I'm in a hurry to catch up with the goods, so I can only do this first, and then go to Gao Qiao to settle accounts with that doggy boy after I'm done!"

Fang Dongping hummed, and turned to look at the milling machine: "Boss Jiang, where are the defective products processed by that milling machine?"

"It's piled up at the door, Mr. Fang, please go and check it for me. I'll replace this gear first."

Fang Dongping nodded, and led Niu Xiaoqiang to the door.

Niu Xiaoqiang reached out to pick up a bearing, and asked in a low voice while checking: "Master, judging from our current work efficiency, I'm afraid that the problem will be solved before lunch, but you asked me to bring it for a change of clothes?" Is it superfluous to bring over my clothes?"

Fang Dongping stared at Niu Xiaoqiang with a half-smile: "Are you worried about making less money, kid?"

Niu Xiaoqiang didn't deny it either: "My fourth sister is about to go to college, and the family is anxiously waiting for money. Of course, I can earn more if I can."

Fang Dongping laughed: "I guessed this a long time ago. The reason why I asked you to bring a change of clothes is because the problem cannot be completely solved."

Niu Xiaoqiang looked at Fang Dongping in astonishment: "Will there be any problems after changing the gear?"

Fang Dongping nodded: "You and I have seen the design drawing of the bearing. The batch of bearings urgently needed by Jiangbei Machinery Factory have such high requirements for precision. The technical requirements are not small, and his technical level is not enough, only I can help him complete the production task by myself."

Fang Dongping is a great expert in mechanical manufacturing. Not only is his theoretical knowledge extremely strong, but his practical ability is also super-class.He can rely on the simplest grinding machine to grind a blank into a bearing that conforms to the specification!This kind of processing technology that relies entirely on experience and feel is comparable to those eighth-level fitters!You must know that the eighth-level fitter is the top existence among the fitters!

The reason why he was selected to go to the Soviet Union for further study was because he had a very high talent in mechanical manufacturing, and his theoretical level and hands-on ability were very strong. Otherwise, this extremely rare opportunity to study abroad would not have come to him. on the head.

Niu Xiaoqiang looked at Fang Dongping with admiration: "Master, you are really amazing!"

Fang Dongping smiled and patted Niu Xiaoqiang on the head: "As long as you follow Master and study hard, you will definitely be as good as me in the future."
