Chapter 31 You lose because you don't understand CNC

40 yuan!

This was not a small sum in 1990. If one ate in the factory's staff canteen, it would be enough to last for half a month.

In fact, Lin Feng also thought about making a bigger bet, but he was a little worried about the reaction of the leaders. After all, it was working hours, after all, it was at the manufacturing site, and he was a little worried that the leaders would come to stop him if he bet 20 yuan.

Fortunately, no leader came over. At this time, the attention of the workshop leaders is probably on the CNC machine tool that has just been unpacked. If they pay attention to this side, it will only attract three or five nearby workers to watch.

Good guy, 20 yuan per person!

The atmosphere at the scene was a little moved, and Hu Xiaoxiao and Ma Xiaoli cheered for Lin Feng in their hearts, the master must win.

"Wang Qiang, I will handle the processing of the first piece. You guys will watch from the sidelines and learn how to operate."

Under Lin Feng's guidance, Wang Qiang was barely able to handle the processing of the first piece, but since the bet was made, Lin Feng decided to do it himself just to be on the safe side.

The parts have been installed on the workbench of the machine tool, and the tools have also been installed. Whether it is a drill bit, a milling cutter, or a boring tool, they are all selected by Lin Feng himself.

After receiving the control handle from Wang Qiang, Lin Feng set the knife himself, found the origin of the coordinates, entered the tool compensation, etc. It didn't take a few minutes, because Lin Feng was very skilled in the operation.

Processing is about to begin!
Lin Feng put down the operating handle of the machine tool, closed the safety door of the machine tool, and said loudly, "The processing of the first piece will start immediately. It is now 42:47 pm. If the processing is not completed by [-]:[-] pm, I will lose."

"Humph!"

Kong Chengde snorted coldly, with a look of disdain, apparently not believing that the processing could be completed in such a short time.

Lin Feng ignored him, took off his Shanghai watch, and said loudly, "Xiaoxiao, tell me the time."

After finishing speaking, he gave the watch to Hu Xiaoxiao, thinking that Hu Xiaoxiao was his apprentice, Lin Feng added, "Squad Leader Hu, you can also time the time, and the processing can be completed within an hour plus or minus 5 minutes, if it is not finished, I will lose If it is processed within this time, it will be regarded as Kong Chengde's loss."

Hu Lin obviously didn't want to offend Lin Feng. Although this guy looks rough and rough, he has a very refined heart. He knows that he will have many parts to be processed by Lin Feng in the future, so Lin Gong can't offend him.

"No problem, I'll keep track of the time for you too." Hu Lin replied.

Processing begins!

Lin Feng pressed the processing button, and the machine tool spindle quickly moved to the position specified by the program with a "swoosh", and then turned quickly, and the milling cutter began to cut.

The milling cutter spins fast!
Everyone is an expert, so you can see it at once. The speed is at least 1500. For ordinary milling machines, the speed is generally at most two or three hundred. Kong Chengde is a milling worker. More than 200 speeds.

Is it such a high speed?

Not only Kong Chengde, but even Hu Lin and the others were slightly surprised!
Noticing their expressions, Lin Feng thought in his heart, what is the speed of [-], that is, if there is no high-quality milling cutter, if there are imported alloy milling cutters, I will increase the milling speed to [-], or even [-].

Lin Feng is now very familiar with this imported CNC five-axis machine. Its processing speed can reach [-] without any problem. Now it is [-], which is pediatrics.

The ideal of CNC milling is high speed and small feed, not only the cutting force is small, it will not affect the accuracy of the machine tool, but also the processing efficiency is extremely high.

Just imagine that ordinary machining generally has a speed of tens of revolutions, or one or two hundred revolutions. Even if you are cutting with high feed, so what, the efficiency is still not high. It takes four hours to process the lugs, and more than three hours to process the six high-precision through holes.

With a cutting speed of [-], the efficiency is still very high even for small feed cutting, several times faster than ordinary milling, and the six lugs are gradually formed at a speed almost visible to the naked eye.

this, this, this...

This is impossible!
It is impossible for the cutting efficiency to be so high. It has only been a few minutes, and it is estimated that in another ten minutes, a total of six lugs will be fully formed.

No, I can't lose, what about 20 yuan, I can't lose...

Kong Chengde said this more than once in his heart, his head turned quickly, thinking about how to not lose.

The machine tool has been processing at a rapid rate, and it probably took only [-] minutes. All six lugs have been processed. In everyone's eyes, the machine tool changed tools quickly again, replacing the milling cutter with a drill bit.

The fixing holes of the six 25 torsion measuring cylinders began to be processed, and the drill bit was seen to rotate rapidly, and the rotational speed was estimated to reach [-].

Still the same, small feed and high-speed cutting, the feed is only 0.1 per revolution, but the speed is too fast. Theoretically, the drilling depth in 1 minute can reach 100 mm.

How thick is the fixed plate, less than 30, almost the first step of processing the first through hole between the two breaths is completed.

Then the second hole, the third hole, the fourth hole...

After the first step of processing the six holes was completed, the machine tool started to change tools quickly again, with a larger drill bit, and started the second step of processing, reaming.

If the precision of the processed hole is not high, it can be done in one step, because this is a high-precision imported CNC machining center.

The precision requirements of the six holes of the torsion measuring cylinder fixed plate are very high. Not only the hole diameter tolerance is only two and a half wires, but the position requirement has also reached five wires.

Then process in three steps, the first step is drilling, the second step is reaming, and the third step is boring.

The processing speed of the first step is very fast, and the processing speed of the second step is not slow. It is completed in a few minutes. The machine tool is automatically changed, and the drill bit is replaced with a boring tool.

The third step is boring, and it is fine boring!

The blade is as thin as silk, and the rotating speed of the boring tool is still very fast. The thin iron filings come out of the hole, the length grows rapidly, and it breaks automatically when it reaches a certain length. It is very enjoyable to watch and very relaxing.

The first hole, the second hole, the third hole...

The processing speed is still very fast, only a few minutes, and a total of six holes are all fine-bored!

With a sound of "咻", the spindle of the machine tool returned to its position, and the processing stopped. Lin Feng opened the safety door of the machine tool, and said loudly, "Everyone, the first part is finished!"

Everyone's eyes are all focused on this part, and a discerning person can see at a glance that the part has indeed been processed.

Hu Xiaoxiao said pleasantly, "It's only 34:52, and it only took [-] minutes!"

What, it only took 52 minutes!

is this real?
Hu Lin nodded, "It really only took 52 minutes, which is simply beyond my imagination. If it is processed on an ordinary machine tool, these two processes will take at least seven or eight hours."

Ordinary machine tools take seven or eight hours, but it only takes 52 minutes on this CNC machine tool, which is amazing.

Sensing everyone's surprised gazes, Lin Feng smiled and thought in his heart, it's because you don't understand numerical control.

After a happy smile, Lin Feng said to Kong Chengde, "You lost, the money belongs to me now."

After finishing speaking, Lin Feng stretched out his hand to put the 40 yuan into his pocket, but Kong Chengde reacted quickly and pressed Lin Feng's hand.
