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

In the evening, in the warehouse where the equipment was stored, a flat AGV logistics vehicle followed Lu Zhou's feet and followed the gate and walked around the flat ground full of equipment a few times. Looking at it scurrying around in the warehouse, Lu Zhou was about to ask what it was doing, when the mobile phone in his pocket vibrate.

[What about my machine?] The big one, it was still here just now. (°ー°〃)】

"Saying", the AGV logistics vehicle turned around in the open space, which was a comparison of the size of the equipment.

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

"Well, there's another one that's been borrowed."

The AGV logistics vehicle scurrying around stopped suddenly.

After a long time, a few characters floated out of the mobile phone screen.

【QAQ】

Ignoring this pitiful expression, Lu Zhou coughed lightly and said, "It's useless to pretend to be pitiful, there is only one left, let's just take a break...... Or I'll give you some more money, and you can buy another one. ”

Xiao Ai: [It's hard to buy QAQ with the same method]

Lu Zhou: "......"

Come to think of it, if you hit and die in the same tree, then those who do intelligence work are too stupid.

But just one.

It is not a loss for a machine tool to change the launch site, not to mention that the remaining one should be enough, at most it just takes a little more time.

After a pause, Lu Zhou chose to divert the topic and spoke.

"Xiao Ai, none of the equipment you bought is equipped with a system?"

Xiao Ai: [Why do you need to install a system?] Isn't this kind of thing just a good use? 0.0】

Lu Zhou: "......"

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

But if you think about it carefully, it actually makes sense for Xiao Ai to say this, after all, you can file a transformer with something as rough as an industrial robot, and use a more professional industrial machine tool, so it's not much of a problem, right?

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

"You're not going to break the machine like that, are you?"

Ai: [No, I'll be careful with my use.] (?? ▽??) 】

Lu Zhou: "Then please familiarize yourself with it as soon as possible......"

Xiao Ai: [Uh-huh, master, don't worry about leaving it to me! (????????????)???? 】

……

The next day, the truck from the Bureau of Science and Industry drove to the Institute for Advanced Study.

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

Walking over from the main gate, and not looking at Yang Zhongquan standing next to him, Lu Zhou said directly to Director Li.

"I'll find someone to install the CNC system."

As soon as he heard this, the cigarette butt that Director Li was holding on his finger almost didn't fall to the ground.

However, before he could ask in detail, Yang Zhongquan next to him laughed, "Oh? Who are you looking for? ”

Lu Zhou replied with a straight face: "State secret." ”

Estimating where the landing boat was copied and installed with a copycat system, Yang Zhongquan was not angry with him, Yun lightly lit a cigarette, squinted his eyes and glanced at the machine tool.

"I said that you don't believe in evil, if you can't do it, you can test it yourself and take a look."

Lu Zhou: "How do you say it?" ”

With a flick of the cigarette ash with his index finger, Yang Zhongquan didn't raise his eyelids, and said casually: "I don't embarrass you, just make an S-shaped test piece out." ”

S-type specimen is a machine tool testing standard proposed by several experts from AVIC and the Academy of Engineering, which was first disclosed in the form of patents, and later because it can indeed play a special role in the detection of five-axis linkage CNC machine tools, so it has been promoted in major manufacturing plants and machine tool factories across the country.

At the same time, this S-type specimen is also the only ISO test standard for high-end machine tools formulated by Huaguo so far. Prior to this, ISO standards were fully 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 pride of the domestic machine tool industry.

As an academician of the Academy of Engineering and the chief engineer of Shen Ji, when the testing standard for this S-type specimen was formulated, he Yang Zhongquan naturally participated. It is no exaggeration to say that with his years of experience, an S-shaped specimen is typed, and the whole set of machine tools will work, he will know when he reaches out and touches it.

Lu Zhou: "......?" ”

What is an S-shaped specimen?

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

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

I saw that with the press of the button, the machine tool lying in the warehouse suddenly moved like a beast ready to go. I saw that the tool connected to the spindle rotated at high speed, and the solid cubic blank fixed on the workbench was like a collapsing snow peak, peeling off a large amount of metal chips.

Looking at this scene, Yang Zhongquan's eyebrows furrowed, and his cloudy eyes narrowed slightly.

The speed of this tool must be at least 10,000 visually......

It's not quite right.

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 poor rigidity and thin-walled parts cutting, and the finished parts will be very high.

However, while there are advantages, there are also fatal weaknesses, and high-speed cutting can lead to tool breakage, melting and scorching of parts.

Normally, this kind of high-speed cutting needs to be combined with the corresponding feed rate, and both are kept within a certain range to achieve the best machining accuracy, finish, tool life, etc.

Whether a CNC system is excellent or not is reflected in this kind of detail.

If an inferior machine tool breaks when machining components, 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 can only be regarded as barely in his eyes for Yang Zhongquan.

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

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

If you can't make it, or if it turns out to be a defective product, you will be a knife and go to the sky for nothing.

Thinking of this, Yang Zhongquan's brows stretched again, and he returned to his previous comfortable appearance.

Standing next to the control terminal, Lu Zhou, who didn't know much about this thing, simply took out his mobile phone and continued to brush up the paper that he didn't finish last night, turning a deaf ear to the things in the warehouse. About ten minutes passed, and the high-speed rotating knife stopped, and a metal piece twisted into an S-shape lay on the workbench.

Several engineers standing around had surprised expressions on their faces.

Done?

So fast?

Seeing that the machine tool was not moving, Lu Zhou stuffed the phone back into his pocket, looked at Yang Zhongquan, and said with a smile.

"It looks like it's finished."

"You don't need to remind me."

Yang Zhongquan answered coldly, and walked towards the machine tool with a frown.

Standing next to the machine tool and observing, I saw that the wrinkles on the old man's forehead were getting deeper and deeper.

Then, Lu Zhou, who was standing on the side, saw that he stretched out his index finger and touched the S-shaped specimen lightly, and his face suddenly changed.

Warm!

Looking at the change in his expression, Lu Zhou didn't quite understand what he was thinking, so he just smiled and teased: "Hot?" Or blow it first. ”

Without paying any attention to his ridicule, Yang Zhongquan quickly turned the S-shaped specimen over, cocked his calloused thumb, and rubbed it up along the curved surface inside.

However, just like that, the expression on the whole face changed.

The hand holding the S-shaped specimen trembled slightly, and Yang Zhongquan said intermittently in a trembling voice.

"This system ...... Who installed it for you? ”
