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 diamond tool cannot process it. If it is a glass, then don't talk about other tools, it must be impossible to process.

This also means that the contract he and Xu Zhenming negotiated before is wasted. If it succeeds, then the cooperation between him and Xu Zhenming can continue. The most important thing is that in addition to the cooperation with Xu Zhenming, He has more 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 mind, that is, their special glass can indeed be processed by machine tools, and it looks good.

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

Due to the big difference between the glass material and steel, 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 should not 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 shaped looked good, like a mirror, and at the same time, there was no one to look at. There are any cracks and gaps on the screw.

Anyway, it is indeed impossible to tell 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 frustration.

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, The precision level has reached the third 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 polishing. He believes that if you use some precision polishing equipment for polishing However, it is not impossible to reach the second level.

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

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

After all, this precision screw rod was basically impossible in their time. Of course, it is not ruled out that 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. produce.

As for Xu Zhenming's factory, it is absolutely impossible to obtain a screw with such precision, even if he has money, he cannot 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 screw rods have reached the standard of three-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. The fastest speed also 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 with a ton of orders!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 was increased by half this time, the accuracy of this screw could not reach the previous ones. It is so high and the error is 8 microns, which means it is just within the third level.So Wang Bin processed more and found that the error was basically between 7 and 8 microns.

This made Wang Bin look a lot 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 classified as level three, but can only be regarded as level four.

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, which is Said that this accuracy is not even four-level.

Then Wang Bin began to debug the machine repeatedly. In the end, the time to process a screw rod was set at 110 seconds, and the accuracy of the machining was between 11 and 12 microns, which was just enough to reach the fourth level of accuracy. Standard look.

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 diamond 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 diamond precision machining tool!It's not the defective products or ordinary diamond knives on the market. The price of each one is thousands of dollars!

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