Chapter 647 Who Installed This System For You?

The expert in Lu Zhou's mouth naturally refers to Xiao Ai.

At night, in the warehouse where the equipment was stored, a flat AGV logistics vehicle followed Lu Zhou into the gate, and strolled a few times on the flat ground full of equipment. Seeing it scurrying around in the warehouse, Lu Zhou was about to ask what it was doing when the phone in his pocket vibrated.

[Where is my machine tool? Such a big one, who was here just now. (°ー°〃)】

"Speaking", the AGV logistics vehicle turned around in the open space, making gestures to measure the size of the equipment.

Looking at the message on the screen, even though Lu Zhou felt that he was thick-skinned, he was a little embarrassed, scratched his cheek and said.

"Uh, another one was borrowed."

The AGV logistics vehicle scurrying around stopped suddenly.

After a long time, a few characters floated on the phone screen.

【QAQ】

Ignoring the pitiful expression, Lu Zhou coughed lightly and said, "It's no use pretending to be pitiful, there's only one left, let's just make it up...or I'll give you some more money, and you can buy another one." tower."

Xiao Ai: [It is difficult to buy QAQ in the same way]

Lu Zhou: "..."

Thinking about it, if they crashed and died on the same tree, then those people engaged in intelligence work would be too stupid.

But just one.

It is not a loss if one machine tool can be changed to another launch site, not to mention that the remaining one should be enough, at most it will just take more time.

After pausing for a moment, Lu Zhou chose to change the subject and spoke.

"Xiao Ai, none of the equipment you bought has a system installed?"

Xiao Ai: [Why do you want to install the system? Isn't this kind of thing easy to use? 0.0】

Lu Zhou: "..."

Although he always felt that this sentence was full of complaints, but for a while he couldn't think of where to start complaining.

But when I think about it carefully, Xiao Ai’s words actually make sense. After all, you can file a Transformer with something as rough as an industrial robot. It’s not a big problem to use a more professional industrial machine tool, right?

Of course, although he believed in Xiao Ai's ability, but out of worry, Lu Zhou asked just in case.

"You won't break the machine tool if you mess around like this?"

Xiao Ai: 【No, I will use it carefully. (▽)】

Lu Zhou: "Then please get acquainted as soon as possible..."

Xiaoai: [Mmm, master, don't worry leave it to me! ()】

...

The next day, a truck from the Bureau of Science and Technology arrived at the Institute for Advanced Study.

A group of people came to the warehouse again, ready to load the machine tools.

Walking over from the main entrance, without looking at Yang Zhongquan who was standing beside him, Lu Zhou said directly to Director Li.

"I found someone to install the CNC system."

Hearing this, Director Li was so startled that the cigarette butt he was holding on his finger almost fell to the ground.

However, before he could ask carefully, Yang Zhongquan beside him laughed, "Oh? Who are you looking for?"

Lu Zhou sternly replied, "It's a state secret."

Guessing that Lu Zhou copied a counterfeit system and installed it, Yang Zhongquan didn't get angry with him, lighted a cigarette calmly, and glanced at the machine tool with squinted eyes.

"I said you don't believe in evil, can you test it yourself?"

Lu Zhou: "How do you measure it?"

Flicking the cigarette ash with his index finger, Yang Zhongquan said casually without raising his eyelids, "I won't make things difficult for you, just make an S-shaped test piece and come out."

The S-type test piece is a machine tool inspection standard proposed by several experts from China Aviation Industry Corporation and the Engineering Academy. Major manufacturing plants and machine tool factories have been promoted.

At the same time, this S-type test piece is so far the only ISO testing standard for high-end machine tools formulated by Huaguo. Prior to this, ISO standards were completely controlled by countries such as the United States, Germany, Italy, France, and Japan.

It can be said that this S-type test piece is one of the prides of the domestic machine tool industry.

As an academician of the Academy of Engineering and the chief engineer of Shenji, Yang Zhongquan naturally participated in the formulation of the testing standards for this S-type test piece. It is no exaggeration to say that based on his many years of experience, if an S-type test piece is produced, he will know if the entire machine tool is working or not.

Lu Zhou: "...?"

What is the S-type test piece?

Fortunately, although he didn't understand, Xiao Ai next to him did.

After walking to the control terminal and standing for a while, Lu Zhou pretended to touch it twice, and then pressed the start button.

With the button pressed, the machine tool lying in the warehouse suddenly moved like a beast ready to go. I saw the tool connected to the spindle rotating at high speed, and the solid cubic blank fixed on the workbench was like a collapsed snow peak, peeling off a large amount of metal debris.

Looking at this scene, Yang Zhongquan frowned, and narrowed his cloudy eyes slightly.

The rotation speed of this tool is estimated to be at least tens of thousands...

Something is wrong.

The benefits of high-speed cutting are obvious. The high-speed removal of chips reduces the cutting force and thermal stress deformation of the workpiece, improves the possibility of cutting parts with poor rigidity and thin-walled parts, and the smoothness of the processed parts will also be high.

However, while there are advantages, the weakness is also fatal. High-speed cutting may lead to tool breakage, melting and burning of parts.

Usually, this kind of high-speed cutting needs to cooperate with the corresponding feed rate, and keep both of them within a certain range, so as to achieve the best machining accuracy, smoothness and tool life.

Whether a numerical control system is excellent is reflected in such details.

If a low-quality machine tool breaks when processing parts, it is not necessarily because of the quality of the tool or the bearing itself, at least half of the possibility is due to the CNC system.

Of course, being able to maintain such a high speed without breaking the knife, to Yang Zhongquan, it can only be regarded as barely falling into his eyes.

This kind of basic operation is nothing to brag about. Shen Ji can do it with many machine tools equipped with imported ceramic bearings and Nissan systems, not to mention the latest five-axis linkage machine tool from Siemens.

This system is not reliable, the key lies in whether it can make things.

If you can't make it, or if it's a defective product, it's useless for you to turn the knife into the sky.

Thinking of this, Yang Zhongquan's brows relaxed again, returning to the previous look of ease.

Standing next to the control terminal, Lu Zhou, who didn't know much about it, simply took out his mobile phone and continued to read the unfinished thesis last night, turning a deaf ear to the things in the warehouse. About ten minutes later, the high-speed rotating cutter stopped, and a metal sheet twisted into an S shape lay on the workbench.

Surprised expressions appeared on the faces of several engineers standing around.

Finished?

So fast?

Seeing that the machine tool was silent, Lu Zhou stuffed his phone back into his pocket, looked at Yang Zhongquan, and said with a smile.

"It seems to be finished."

"You don't need to remind me."

Yang Zhongquan responded coldly, frowned and walked towards the machine tool.

Standing next to the machine tool and observing for a while, I saw that the wrinkles on the old man's forehead became deeper and deeper.

Then, Lu Zhou, who was standing aside, saw that he stretched out his index finger and lightly touched the S-shaped test piece, and his expression changed suddenly.

Warm!

Looking at the change in his expression, Lu Zhou didn't really understand what he was thinking, but just laughed and joked: "It's hot? Why don't you blow it first."

Not paying attention to his ridicule at all, Yang Zhongquan quickly turned the S-shaped test piece over, raised his calloused thumb, and rubbed it upwards along the inner curved surface.

However, with just such a rubbing, the expression on that entire face changed.

The hand holding the S-shaped test piece trembled slightly, and Yang Zhongquan spoke intermittently in a trembling voice.

"This system... who installed it for you?"
