Super Craftsman Chapter 72

Chapter 72 - high precision lathe (2)

Obviously, this was not the time to fulfill Guo Tai Lai's dream, but the time for Professor Wang to be stunned.

Receiving Elder Liu's call, Professor Wang rushed to his side in a hurry. Fortunately, it was 9003. Although Elder Liu didn't say anything on the phone, he had worked with Elder Liu for so many years, how could he not recognize the excitement in Elder Liu's tone?

Professor Wang was also very curious, what kind of lathe did Guo Tai Lai actually assemble?

Previously, when he announced this assembly project, it was also for Guo Tai Lai to assemble and practise, it was very helpful for the new processing center's design. However, the high precision gyro proved everything when Guo Tai came out. He no longer needed to train with a car-loading bed.

However, it was hard to revoke an approved project. Guo Tailai finally decided to make a move. He wanted to apply for a new customized motor, but he couldn't approve this. After that, Guo Tai Lai did not apply for funding and started working with the work that he had already applied for, so the Professor Wang did not pay attention to it anymore. At this time, suddenly receiving Elder Liu's excited phone call, could something that could make Elder Liu excited be something simple?

Although it was made on the old lathe's bed, Guo Tailai still fixed the old bed. The whole lathe shined brilliantly. Its appearance was the design of a future dream, and it seemed to be very tall.

Professor Wang did not care about the appearance, he was more interested in the performance. When the electric motor started, Professor Wang immediately sensed that something was amiss. Although Professor Wang was not an electromechanical professor, how could he miss the part about the electric motor when he designed high precision CNC? The experienced Professor Wang didn't need to look to know the quality of the electric motor just from the sound of the voice, not to mention that Guo Tai Lai's coin had still been standing there, and didn't fall down.

From the coin that was standing, he could see the electric motor, causing Professor Wang's face to immediately change. What type of electric machine is this? Why is there no sign and no manufacturer? But why did that new motor housing look a little familiar?

No, it was not because the motor shell looked familiar, but because of the surface roughness of the motor shell. This pure metal motor shell was actually made with high precision? Which manufacturer would be so extravagant?

"You did it?" Professor Wang immediately thought of the whole story, didn't Elder Liu's previous request to buy the electric motor get rejected? Since there was no money, it was impossible to purchase them from the outside. Furthermore, with such high processing precision, Professor Wang immediately recognized that it was Guo Tai Lai's work.

"Everything from inside to outside, including the winding wires and even the coils, was created by Fatty himself." Before Guo Tai could say anything, Old Liu cut in. "For this, Pang Zi has been learning coil winding from one of my old buddies for a whole week. What do you think?"

"A masterpiece!" Professor Wang stared at the electric machine, his eyes unable to move, "How do I control the speed? What did the control A.I. Chip choose? "

"Relying entirely on voltage control." Speaking of technical problems, Elder Liu couldn't do anything. He could only ask Guo Tailai, "You know I'm still lacking in industrial control software, so I can only control it in the simplest way."

"Good!" "Alright!" Professor Wang didn't know how to describe his feelings anymore. This motor alone was enough to excite him. And this was only for voltage control. If it was changed to chip stepper control, wouldn't it be even better than the best electrical machine they had?

Professor Wang only needed a few looks to directly master the pure mechanical lathe. He rejected Guo Tailai's offer to demonstrate and did it himself. There was nothing more accurate than personally experiencing the test result.

However, when he saw the label on the ruler that was specially designed, he was dumbfounded.

"One micron of accuracy?" Professor Wang could not believe his eyes. "Can it be done?"

"Whether I can do it or not, I'll just have to give it a try and see how it goes." Elder Liu chuckled as he handed over a half finished product to Professor Wang.

Professor Wang skillfully clamped the parts together. Before making his move, he first used micrometer to carefully measure the dimensions of the parts. Then, he adjusted the scale and started the lathe.

When the carriage was halfway done, it looked as thin as a cow's hair. No, even thinner than cow hair was being drawn out from the tip of the blade. Professor Wang had already believed that it was more than half of it. Suppressing his excitement, Professor Wang waited for the blade to finish moving. After the retracting blade was switched off, he took out the micrometer and measured it in detail.

Due to his excitement, the micrometer did not go to the right place two or three times. Guo Tai Lai tried to help, but he was stopped by him instead.

If it was a high precision numerical control machine tool, it would not be weird for it to be this precise. However, it was a semi-automatic mechanical lathe! All of it is mechanical linkage, and even the motor changes speed by means of voltage changes rather than by controlling the chip. God! How was this possible?

If it was an amateur, to be able to achieve such an accuracy for this lathe, it would probably only be an "oh", and then he would exclaim, "Amazing, everything will be gone."

However, the Professor Wang was an absolute expert, the technical content displayed by the mechanical lathe was simply outrageous. No one could describe it with words.

Just that gear box, with so many combinations of gears, to be able to transmit power without causing more than a millimetre of vibration, that was an unimaginable exaggeration. But the problem was, to be able to manually control the ruler to move the knife to a precision of 1 micron, was something that could be done by a human.

To put it crudely, the lathe was unmoved and was removed. If it was installed by someone else, the accuracy of the lathe would have been increased by tenfold. With at least one micron of movement driven by four gears working together, he was able to instantly kill any assembly master that Professor Wang knew, even Elder Liu was unable to do so.

More exaggeratedly, this lathe was designed and assembled by Fatty Guo from head to toe. This was a reflection of Guo's mastery in designing, manufacturing and assembling. Even if it was the Professor Wang himself, who knew how to design such a precise lathe according to the highest level of processing accuracy, it was just this and nothing more, unable to be created.

From the moment he confirmed the accuracy of the lathe, Professor Wang knew that he had picked up a huge bargain. Last year, he immediately accepted Guo Tai to be his graduate student, that was the right decision. With Guo Tailai around, many of the detailed designs in his mind could be fully implemented.

In the past, he was worried about being able to design but not being able to create it. It seemed that he would have to consider how to optimize the design in the future in order to live up to his craftsmanship. Such a craft, in the future the country's high precision numerical control will develop to what height?
