The expert that Lu Zhou was talking about was obviously Xiao Ai.
At night, in the warehouse where the batch of equipment was stored, a flat AGV followed Lu Zhou's footsteps into the warehouse. It circled around the warehouse full of equipment. Lu Zhou looked at it running around in the warehouse and was about to ask what it was doing when his phone in his pocket vibrated.
[Where's my machine tool? It's so big, it was here a second ago. (° ー ° 〃)]
As it "spoke", the AGV logistics vehicle made a circle on the empty ground, which could be considered as a comparison of the size of the equipment.
Lu Zhou looked at the message on the screen and felt a little embarrassed. He scratched his cheek and spoke.
"Uh, the other one was borrowed by someone else."
The AGV that was running around suddenly stopped.
After a while, a few words appeared on the phone screen.
[QAQ]
Lu Zhou ignored the pitiful expression and coughed. He said, "There's no point pretending to be pitiful, there's only one left … How about I give you some money and you go buy another one?"
Xiao Ai: [It's hard to buy another one using the same method. QAQ]
Lu Zhou: "…"
I think about it, it makes sense. If I kill myself on the same tree, then those intelligence workers are too stupid.
But I'll just have to buy one.
One machine tool for a launch site is worth it. Not to mention that the remaining one should be enough. It'll just take a bit more time.
Lu Zhou paused for a second and changed the topic.
"Xiao Ai, you didn't install a system on the equipment you bought?"
Xiao Ai: [Why would I install a system? Can't you learn it after using it? 0.0】
Lu Zhou: "…"
Although he felt that there was something wrong with this sentence, he didn't know where to start.
However, when he thought about it carefully, Xiao Ai's words actually made sense. After all, he could file a Transformer with something as crude as an industrial robot. Using a more professional industrial machine tool shouldn't be a problem, right?
Of course, although he believed in Xiao Ai's ability, out of worry, Lu Zhou still asked just in case.
"You won't break the machine, will you?"
Xiao Ai: [I won't. I'll be careful. (?? ▽??)]
Lu Zhou: "Then please familiarize yourself with it as soon as possible …"
Xiao Ai: [Yes, Master, leave it to me! (?????)????】
…
The next day, the State Administration for National Defense's truck arrived at the Institute for Advanced Study.
The group of people once again came to the warehouse, ready to load the machine tools.
Lu Zhou walked over from the main entrance. Without looking at Yang Zhongquan standing next to him, he spoke directly to Director Li.
"I found someone to install the CNC system."
Director Li was so shocked that he almost dropped the cigarette in his hand.
However, before he could ask in detail, Yang Zhongquan, who was beside him, chuckled. "Oh? Who did you find? "
Lu Zhou replied, "It's a state secret."
Yang Zhongquan guessed that Lu Zhou must have installed a counterfeit system, so he did not argue with Lu Zhou. He lit a cigarette and glanced at the machine tool.
"If you don't believe me, why don't you test it yourself?"
Lu Zhou: "How do you want to test it?"
Yang Zhongquan flicked his cigarette and said, "I won't make it difficult for you, I'll just make an S-shaped sample."
The S-type test was a machine tool testing standard proposed by experts from China Aerospace and the Academy of Engineering. It was first published in the form of a patent. Later on, because it could play a special role in testing five-axis linkage CNC machine tools, it was popularized by major manufacturers and machine tool factories across the country.
At the same time, this S-type test piece was the only ISO test standard for high-end machine tools developed by China. Prior to this, the ISO standard was completely controlled by countries such as the United States, Germany, Italy, France, and Japan.
It could be said that the S-type test was one of the pride of the domestic machine tool industry.
As an academician of the Academy of Engineering and the chief engineer of Shenyang Machine Tool, Yang Zhongquan naturally participated in the development of the S-type test standard. It was no exaggeration to say that with his many years of experience, if the S-type test was made, he could easily tell if the entire machine tool was good or not.
Lu Zhou: "…?"
What the hell is an S-type test?
Fortunately, even though he didn't understand, Xiao Ai did.
Lu Zhou walked in front of the control terminal and pretended to touch it. He then pressed the start button.
As the button was pressed, the machine tool lying in the warehouse suddenly moved like a beast that was ready to go. The tool connected to the spindle rotated at a high speed, and the solid cube blank fixed on the workbench was like a collapsing snowy peak, peeling off a large amount of metal debris.
Yang Zhongquan looked at this scene and frowned. His cloudy eyes slightly narrowed.
The speed of the tool is at least tens of thousands …
Something's not right.
The benefits of high-speed cutting were obvious. The high-speed removal of the chips reduced the cutting force and thermal stress deformation of the workpiece. This improved the possibility of machining parts with poor rigidity and thin-walled parts. The finished parts would also have a high degree of smoothness.
However, while there were advantages, there were also fatal weaknesses. High-speed cutting could lead to the melting and burning of parts.
Normally, this kind of high-speed cutting required a corresponding feed speed as a coordination. Both must be maintained within a certain range to maximize the precision and smoothness of the tool.
The excellence of a CNC system was reflected in these details.
If a low-quality machine tool broke during processing, it wasn't necessarily because of the quality of the tool or the bearing itself. There was at least a 50% chance that the problem was with the CNC system.
Of course, for Yang Zhongquan to be able to maintain such a high rotation speed without breaking the saber, it was only barely enough to catch his eye.
This kind of basic operation was nothing to brag about. A lot of Shenyang machine tools with imported ceramic bearings and Japanese systems could do this, let alone the latest five-axis linkage machine tool from Siemens.
Whether or not this system was reliable depended on whether or not it could be made.
If you can't make it, or if it's a defective product, then even if you're a knife, it's useless.
Yang Zhongquan's eyebrows relaxed again, and he returned to his previous relaxed look.
Lu Zhou stood next to the control terminal and took out his phone. He didn't know much about this stuff, so he continued to read the thesis from last night. He turned a deaf ear to what was happening in the warehouse. After around ten minutes, the high-speed rotating tool stopped, and an S-shaped piece of metal lay on the workbench.
The engineers standing around all had surprised expressions on their faces.
It's done?
That fast?
Lu Zhou put his phone back into his pocket and looked at Yang Zhongquan.
He smiled and said, "I think it's done."
"I don't need you to remind me."
Yang Zhongquan responded coldly and walked toward the machine tool with a frown.
He stood next to the machine tool and saw that the wrinkles on the old man's forehead were getting deeper and deeper.
Then, Lu Zhou saw the old man reach out his index finger and gently touch the S-shaped test piece. His face suddenly changed.
It's warm!
Lu Zhou looked at the change in his expression. He didn't quite understand what he was thinking. He just smiled and said, "You're scalded? How about you blow on it first? "
Yang Zhongquan didn't care about his teasing at all. He quickly flipped the S-shaped test piece over and rubbed his calloused thumb along the curved surface of the inner surface.
However, the moment he rubbed it, the expression on his face changed.
Yang Zhongquan's hand trembled as he spoke with a trembling voice.
"This system … Who installed it for you?"
