Super Craftsman

Obviously, it is not the time to realize Guo Tailai’s dream, but it is when Professor Wang was shocked.

Upon receiving the call from Liu Lao, Professor Wang immediately rushed to the dust-free workplace. Fortunately, they are all at 900. Although Liu Lao didn’t say anything on the phone, he has been working with Liu Lao for many years. Can he not hear the excitement in Liu Lao’s tone?

Professor Wang is also very curious in his heart, Guo Tailai assembled a kind of lathe out.

When I applied for this assembly project before, it was also to let Guo Tailai assemble and practice, which is very helpful for the design of the new machining center of Professor Wang. However, when Guo Tailai came to the division, the high-precision gyro proved everything. Guo Tailai had no need to assemble a lathe to practice his hand.

However, it has been difficult to cancel the approved projects. Later, Guo Tailai decided to start the operation. If he wants to apply for a new motor, this can no longer be approved. Later, Guo Tailai simply did not apply for funds, but started to work with the application already applied. Professor Wang also stopped paying attention for a while. At this time, he suddenly received a phone call from Liu Lao, who could make Liu Lao still excited. Is it a simple thing?

Although it was remade on the bed of the old lathe, Guo Tailai still trimmed the old bed. The entire lathe is bright and the shape is used in the design of the future dreams, it is very tall.

Professor Wang does not care about the shape, he is interested in performance. When the motor started, Professor Wang immediately noticed that it was wrong. Although Professor Wang is not a professor of the electrical department, how can he design a high-precision numerical control with less motor rings? Professor Wang, who is experienced, doesn't have to look at it. He can hear the sound of the motor only by listening to the sound. What's more, the coin that Guo Tailai stood on has been standing there, and he has not fallen down.

When I saw the motor from the standing coin, Professor Wang’s face changed immediately. What type of motor is this? Why are there no manufacturers without signs? But why look at the brand new motor casing a bit familiar?

No, not the motor shell is familiar, but the surface roughness of the motor shell. Is this pure metal motor shell actually processed with high precision? Which manufacturer will be so extravagant?

“What did you do?” Professor Wang immediately thought of the original committee. Was the budget for Liu Lao’s report to apply for motor purchase not been dismissed? Since there is no funding, it is impossible to purchase from outside. With such high processing precision, Professor Wang immediately realized that it was Guo Tailai's work.

"From the inside out, including the winding of each wire or even the coil group, all made by the fat man." Guo Tailai has not spoken yet, Liu Lao is in the side of the socket: "For this, the fat man followed me. The old man learned a whole week of winding coils, how about?"

"Masterpiece!" Professor Wang stared at the motor and couldn't move his eyes: "How do you control the speed? What is the control chip?"

“It’s completely dependent on voltage control.” When it comes to technical problems, Liu Lao will not work. It’s only Guo Tailai’s opening: “You also know that I’m still lacking in industrial control software and can only use the simplest method to control it. ""

"Good! Good!" Professor Wang has no idea how to describe his feelings. It was this motor that made him excited. This is just voltage control. If it is changed to chip step control, is it better than the best purchased motor that they use now?

Pure mechanical lathe, Professor Wang can directly get started with a few eyes. He directly rejected Guo Tailai's plan to demonstrate, and he did it himself. There is no more accurate test results than I have personally experienced.

However, when he saw the label on the specially designed ruler, he was stupid on the spot.

“1 micron accuracy?” Professor Wang couldn’t believe his eyes: “Can it be done?”

"Can you do it, don't you know it?" Liu Laojiao smiled and handed Professor Wang a semi-finished part.

Professor Wang skillfully clamped the parts. Before starting the hand, he carefully measured the current dimensions of the parts with a dial gauge, then adjusted the ruler and started the lathe.

Only half of the car, watching the fine hair, no, the wire is thinner than the cow hair on the tip of the knife, Professor Wang has already believed most of it. Resist the excitement, waiting for the knife to finish, after the knife was shut down, Professor Wang took the dial gauge again and measured it again.

Because of the excitement, Professor Wang did not rely on the two or three dial gauges. Guo Tailai wanted to help him to be stopped by him. It was hard to measure it all in several directions. Looking at the reading above, Professor Wang once His eyes widened and his face was incredible.

If this is a high-precision CNC machine tool, then it is not surprising to reach this precision, but this is a semi-manual semi-automatic mechanical lathe! Everything is mechanically linked, even the motor is simply changing the speed by voltage changes instead of controlling the chip. God! How can this be?

If it is a layman, this precision can be achieved for this lathe. It is estimated that it is a sigh, then I am amazed, it is great, and everything is gone.

Professor Wang is an absolute expert. The technical content of this mechanical lathe is simply ridiculous, and people can't describe it in words.

It’s the gearbox. So many combinations of gears are used to transmit power without causing vibrations in excess of millimeters. That’s unimaginable exaggeration. The problem is that the manual control of the ruler can be accurate. To 1 micron, is this something that people can do?

To put it bluntly, the lathe is unpacked and replaced, and for personal installation, the accuracy can be reduced by ten times. The fine movement of 1 micron driven by at least four gears smashes any assembly master known to Professor Wang, and even Liu Lao will not.

More exaggerated is that this lathe is also designed and manufactured by Guo Fatzi from head to toe. This reflects Guo Tailai's mastery in design, manufacture and assembly. Even if Professor Wang himself, he may be able to design such a precise lathe according to the highest level of machining accuracy, but that is nothing more than that.

From the confirmation of the accuracy of this lathe, Professor Wang knew that he was absolutely a big bargain. Last year, it was the most correct decision to take Guo Tailai as a graduate student. There is Guo Tailai, and many fine designs in his mind can be realized.

What I used to worry about is that it can be designed but not made. It seems that in the future, we must consider how to optimize the design to be able to stand up to such a craft. With such a craft, what kind of height will the high-precision CNC of the country develop in the future?
