When the high-speed rotating glass column and the chip cutter on the drill bit approached slowly, Wang Bin was also nervous. After all, the performance of this glass is here. If even the diamond cutter can''t process this glass, don''t say that other cutters must be unable to process.

    This means that the contract he negotiated with Xu Zhenming will be in vain. If it is successful, the cooperation between him and Xu Zhenming can continue. Most importantly, in addition to the cooperation with Xu Zhenming, he has more things to sell in the mall.

    After all, we can use glass to produce ball screws, so we can produce a lot of mechanical parts with this kind of glass.

    Finally, the glass column and the cutting tool slowly approached together. At the same time, the water pipe next to the cutting tool also ejected coolant. Under the processing of the cutting tool, the white substances were taken away under the impact of the water flow, and the original smooth and flat glass column also changed.

    When Wang Bin saw all this, he finally put down half of his heart. That is, their special glass can indeed be processed by machine tools, and the effect looks good.

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

    Because the material of glass is very different from that of steel, and their 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 is automatically opened.

    Wang Bin immediately picked up the processed glass column. No, it should not be called a glass column now, but a glass screw rod.

    He picked up some warm glass screw rods due to processing and looked at them carefully. He found that the screw rod that had been processed and formed looked good like a mirror. At the same time, he didn''t see any cracks and gaps on the screw rod.

    Anyway, the naked eye can''t see what''s wrong with the screw rod processed from special glass, but Wang Bin''s face doesn''t look excited or depressed.

    He silently picked up the high-precision laser detector from the random bed in the laboratory, began to test the screw rod made of glass, and soon had the results.

    When the test results came out, Wang Bin also had a smile on his face. The test results showed that the glass screw rod had an arbitrary length of 300 mm, and the error was about 5 microns. In other words, the precision level of this screw rod processed from glass had reached level 3, which was very close to the precision of level 2 screw rod, Moreover, without any polishing, he believes that it is not impossible to achieve level II if some precision grinding equipment is used for polishing.

    After thinking about it, Wang Bin picked up a glass column and put it into the processing center, and started the machine. After all, only one glass screw was processed, so it is impossible to determine the average accuracy of the ball screw processed by this glass. If it is around this, Wang Bin should consider whether to buy some high-precision polishing equipment.

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

    After all, this precision screw rod was basically impossible in their era. Of course, it cannot be 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 can not be produced on a large scale.

    It is absolutely impossible for Xu Zhenming''s factory to get such a precision screw rod. Even if he has money, he can''t buy it.

    Soon, two hours passed while Wang Bin was busy. At the same time, Wang Bin also processed 13 glass screws, and the precision grade of these glass screws just processed by him reached between 5 and 6 microns, that is to say, these screws reached the standard of three-level precision.

    This greatly relieved Wang Bin, but Wang Bin also had some troubles at this time, that is, the processing speed is too slow. The fastest speed also takes nearly ten minutes to process an 80mm screw rod, and only six screws can be processed in an hour, which made Wang Bin very angry.

    After all, in the science and technology mall, Xu Zhenming''s order has a screw rod with a ton of order! A ton! How long will it take to process it!

    Wang Bin thought about it and began to adjust the control panel of the machine tool, increasing the processing speed to about one in five minutes, and then put in a glass column to continue to start the machine tool.

    Soon five minutes passed, and the glass column previously put into the machine tool became a screw rod.

    So Wang Bin immediately took the lead screw out of the machine tool, and then tested its accuracy. However, because the processing speed was increased by half, the accuracy of the lead screw could not reach the previous high, and the error was 8 microns, that is to say, it was just within the three-level range. So Wang Bin processed more and found that the errors were basically between 7 and 8 microns.

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

    Two minutes later, the processed screw rod after re debugging was finally completed, and Wang Bin naturally tested it. The results of this test were much worse than those before, and the error reached 10 microns. It is obvious that such accuracy is not level 3, but level 4.

    However, Wang Bin was still dissatisfied with this and began to continue debugging on the machine tool. He continued to shorten the time by half on the original basis. However, after processing and testing, the accuracy error actually reached the level of 15 microns, that is to say, this accuracy is not even level 4.

    Then Wang Bin began to repeatedly debug the machine tool. Finally, the processing time of a screw rod was set at 110 seconds, and the processing accuracy was between 11 and 12 microns, that is, it was just about to reach the level 4 accuracy standard.

    After debugging, Wang Bin stopped the machine tool, carefully inspected the tools on the machine tool, and even tested these tools with testing equipment. However, the result made Wang Bin''s face not very good, that is, even if he used diamond tools to process their glass, its wear rate was very fast, and it was basically processed for a day or two, The main tools must be replaced.

    You know, this is a real diamond precision machining tool! Not those defective products or ordinary diamond tools on the market. The price of each one is thousands of the cheapest!

    But then he thought about the price of these screw rods, and his mood was much better.
