Chapter 39 Processing Test

When the high-speed rotating glass column and the chip knife on the drill were slowly approaching, Wang Bin’s heart was also a little nervous at this time. After all, the performance of this glass is placed here. If even the Vajra stone tool can’t be processed For this type of glass, let alone other tools, it must be impossible to process.

This also means that the contract he negotiated with Xu Zhenming was wasted. If it succeeds, then the cooperation between him and Xu Zhenming can continue. Most importantly, in addition to the cooperation with Xu Zhenming, He has a lot of things for sale in the mall.

After all, it is possible to use glass to produce ball screws, so with this type of glass, many mechanical parts can be produced.

Finally, the glass column and the cutter slowly approached together. At the same time, the water pipe beside the cutter also sprayed out the coolant. The glass column was processed by the cutter, and strips of white matter were carried under the impact of the water stream. Go, and the original smooth and flat glass column has also changed.

When Wang Bin saw all this, he finally let go of his heart, that is, their special glass can indeed be processed by machine tools, and the effect seems to be good.

However, it is still uncertain whether this glass can be precision processed.

Because the material of glass is very different from steel, and the performance of this glass is even better.

For example, the hardness is much higher than that of ordinary glass, so the processing speed is not fast. It took more than ten minutes for the machine tool to stop, and the door of the machine tool processing room was automatically opened.

Wang Bin immediately picked up the processed glass column. No, it shouldn’t be called a glass column now, but should be called a glass threaded rod.

Picking up the glass threaded rod that was somewhat warm due to processing, and looking at it carefully, he found that the threaded rod that had been processed and formed looked good, like a mirror, and at the same time, he did not look at this one. There are any cracks and gaps on the screw rod.

Anyway, it is indeed impossible to see with the naked eye that there is something wrong with this screw made of special glass, but Wang Bin’s face is not excited, of course, there is no trace of discouragement.

He silently picked up the high-precision laser detector that followed the machine tool in the laboratory, and began to test the screw made of glass, and soon the results were obtained.

When the test results came out, Wang Bin’s face also showed a smile. The test results showed that the error of any 300 mm length of this glass screw is about 5 microns, that is to say, this screw made of glass, Its precision level has reached the third-level level, and it is very close to the precision of the second-level screw, and this is still in the absence of any polishing and grinding. He believes that if some precision grinding equipment is used for a If you want to polish it, it is not impossible to achieve a second-level level.

After thinking about it, Wang Bin picked up a glass column and put it inside the machining center, and started the machine. After all, only a glass screw was processed, so the average precision of the ball screw processed by this glass is still uncertain. If If they are all around this, then Wang Bin must consider whether he is going to buy some high-precision polishing equipment.

If it can achieve second-level accuracy, then the price can be higher when it is sold to Xu Zhenming.

After all, this precision screw rod was basically impossible in their time. Of course, it can be processed, but it must be in some secret units, and it can only be processed in a small amount, which cannot be large-scale. Production.

As for Xu Zhenming’s factory, it is absolutely impossible to obtain a screw with such precision, even if he has money, he can’t buy it.

Soon, two hours passed in Wang Bin’s busy schedule. At the same time, Wang Bin also processed 13 glass thread rods, and the precision grades of these glass thread rods just processed by him reached between 5 and 6 microns. , Which means that these screws have reached the standard of third-level accuracy.

This made Wang Bin greatly relieved, but Wang Bin also has some troubles at this time, that is, the processing speed is too slow, and the fastest speed takes nearly ten minutes to process an 80 mm silk. Only six rods can be processed in an hour, which makes Wang Bin very annoyed.

After all, Xu Zhenming’s order in the science and technology mall is a screw rod with a one ton order! A ton! How long does it take to process it!

Wang Bin thought for a while, and started to adjust the control panel of the machine again, increasing the processing speed to about five minutes, and then put a glass column in and continued to start the machine.

Soon five minutes passed, and the glass column previously placed in the machine tool became a screw.

So Wang Bin immediately took this screw out of the machine tool, and then carried out an accuracy test on it, but because the processing speed Ascension is half of this time, the accuracy of this screw cannot reach the previous ones. At this high level, the error is within 8 microns, which means it just happens to be within the third-level range. So Wang Bin processed more and found that the error was basically between 7 and 8 microns.

This made Wang Bin look better, but he was not satisfied with it. Instead, he continued to adjust the data on the control panel of the machine tool, doubled the speed again, and tried again.

Two minutes later, after re-commissioning, the processed screw rod was finally completed, and Wang Bin naturally inspected it again. The results of this inspection are much worse than the previous ones in terms of accuracy, with an error of 10 microns. Obviously, this kind of accuracy is no longer third-level, it can only be regarded as fourth-level accuracy.

However, Wang Bin was still dissatisfied with this, and began to debug on the machine tool, and continued to shorten the time by half on the original basis. However, after processing and testing, the accuracy error reached 15 microns, that is, Said this accuracy is not even fourth-level.

Subsequently, Wang Bin began to debug the machine repeatedly. In the end, the processing time for a screw rod was set at 110 seconds, and the processing accuracy was between 11 and 12 microns, which was just right to reach the fourth-level. What the accuracy standards look like.

After debugging, Wang Bin stopped the machine tool and carefully inspected the tools on the machine tool, and even inspected these tools with inspection equipment. However, Wang Bin’s face was not very good, so even if They use Vajra stone tools to process their glass, and the wear rate is also very fast. Basically, after a day or two of processing, the main tools must be replaced.

You know this is a real Vajra stone precision machining tool! It’s not the defective products or ordinary Vajra stone knives on the market. The price of each one, the cheapest one is several thousand!

But then he thought about the price of these screws, and his mood improved a lot.
