"Later, Professor Chen Guoliang discovered after inspection that a shaft inside the machine tool had some deviation during rotation!"
"Professor Chen then corrected this shaft!"
"Then he completely replaced the shaft with a new one, but it still didn't work!"
Liu Kai Xuan said solemnly, "I also discovered the problems that Professor Chen found!"
"While replacing the gears, I also corrected the shaft!"
"However, this machine tool actually has some other issues that Professor Chen might have overlooked!"
"Other issues?" Li Guowei asked, "What issues?"
"Heh heh..."
Liu Kai Xuan replied with a chuckle, "Since Professor Li has already seen it, there's no need for me to show off my humble skills, right?"
"No trouble at all!"
Li Guowei waved his hand with a smile, "Let's just consider it an academic sparring session!"
"It's rare to have the opportunity to interact with such an excellent young talent like Director Liu today. I'm already eager!"
Strictly speaking, this old guy Li Guowei was a complete "bookworm."
The old man had dedicated his life to academic research. Even in retirement, he couldn't sit still.
"Since Professor Li is so enthusiastic, let's have a good chat!"
Liu Kai Xuan continued, "This machine tool is an antique!"
"It's something left behind by the island nation back then. After the country integrated resources, it was allocated for use by Dongxing Heavy Industry Factory!"
"It was already an old machine, and after working in Dongxing Heavy Industry Factory for so many years, the internal aging problem is very serious!"
"Therefore, when we inspect the machine, we will prioritize replacing damaged parts to ensure the machine can operate normally!"
Li Guowei nodded in agreement, "In principle, that's indeed how it is!"
Liu Kai Xuan then changed the subject, "The problem lies precisely here!"
"The parts of this old model of machine tool are severely worn!"
"Both gears on the same shaft have varying degrees of wear!"
"Simply replacing one side's gears is definitely not enough!"
Li Guowei couldn't help but laugh, "Director Liu Kai Xuan, I beg to differ with your point of view!"
"I am naturally aware of the situation you're describing, and Professor Chen, who came to repair it, is also aware of it."
"The issue you mentioned has already been perfectly resolved. The angle of the machine tool's shaft is adjustable!"
"In the situation you described earlier, we only need to adjust the shaft angle; there's no need to replace the entire set!"
"Of course, my point is not to argue about whether that one gear should be replaced!"
"What I mean is, even if you replace one more gear, it won't fundamentally solve the problem!"
Liu Kai Xuan said solemnly, "Then how do you think this problem should be handled?"
Li Guowei thought for a moment and said, "I believe this is a systemic failure!"
"This machine tool has a very high degree of wear and tear, and it's long overdue for a complete overhaul!"
"Why not just replace the entire gearbox that's malfunctioning!"
"Although the workload is a bit large, it's all worth it as long as it can restore the machine tool to normal operation!"
"Heh heh..."
Liu Kai Xuan nodded and smiled, "Professor Li is indeed... profoundly learned. I am impressed!"
"Me!" Li Guowei's old face instantly turned red all the way to his neck.
After all, old man Li Guowei was not an idiot.
He could naturally tell that Liu Kai Xuan's words just now were not genuine flattery.
Good heavens, a few small gears inside a machine tool, and he immediately suggests replacing the entire gearbox assembly.
Is this the level of a seasoned professor from a prestigious university of technology?
However, Liu Kai Xuan's words were very subtle, giving Li Guowei ample face.
Replacing gears, shafts, and other small parts is not a major issue for a factory.
These small parts can be produced domestically, and a batch of them can be procured.
But replacing the entire gearbox assembly is different. With China's current technological level, it cannot be manufactured yet.
If it needs to be replaced, parts will have to be imported from abroad.
In that case, the final cost would be comparable to inviting a foreign expert, wouldn't it?
Suppressing his anxiety, Li Guowei continued, "Alright, Director Liu!"
"What you said earlier has some merit. Let's proceed with the repairs according to your plan now!"
"I won't offer any more opinions for now. We can discuss it later after seeing the results of your repairs."
This old guy Li Guowei's fighting spirit had been thoroughly ignited.
Today, he would use his life experience to teach this arrogant and conceited young man a lesson.
Later, when Liu Kai Xuan fails to resolve the machine tool's fault with his repair plan, he will realize how brilliant his own repair plan is.
"Hahaha..."
Liu Kai Xuan just nodded and smiled in response to Li Guowei's challenge, saying nothing more.
On the first day Liu Kai Xuan started as an apprentice at Hongxing Steel Rolling Mill, his master Liu Dakui had personally told him.
All departments in the entire factory operated based on favors, connections, and relationships.
Only the technical department was different; it did not operate on favors, connections, or relationships.
To succeed here, one could only rely on one's own strength.
Later, through his own efforts, Liu Kai Xuan went from being an ordinary apprentice to a senior engineer, overcoming numerous obstacles.
The hardships and setbacks he experienced in this process were something ordinary people could not comprehend.
Li Guowei was Li Ya's grandfather, so Liu Kai Xuan had given him a little face earlier.
However, since the old man insisted on pursuing this matter, Liu Kai Xuan saw no need to give him any more face.
Liu Kai Xuan followed his own approach and fixed the machine tool's fault.
After the machine tool was assembled, Liu Kai Xuan personally operated it for a few minutes.
After confirming there were no issues, Dongxing Heavy Industry Factory also sent two master technicians to test the operation.
Finally, this machine tool operated perfectly for 20 minutes without any further malfunctions!
"Alright, Director Liu has completely repaired this machine tool!"
The master technicians were overjoyed when the machine tool passed their tests.
"Hahaha, Comrade Liu Kai Xuan, you are truly extraordinary!"
Chen Haohai was so happy he couldn't close his mouth after hearing the news, "You've so easily solved problems that even the experts and professors couldn't!"
"You are indeed a young man of great promise!"
