Chapter 39 Processing Test
Just as the high-speed rotating glass column and the chip knife on the drill bit slowly approached, Wang Bin was also a little nervous at this time. After all, the performance of this glass is placed here. If even diamond knives cannot process this glass, then don’t mention other knives, it will definitely not be able to process them.
This means that the contract he and Xu Zhenming had negotiated before was in vain. If it was successful, the cooperation between him and Xu Zhenming could continue. The most important thing is that in addition to the cooperation with Xu Zhenming, he also had more things to sell in the mall.
After all, glass can be used to produce ball screws, so using this kind of glass can produce many mechanical parts.
Finally, the glass column and the tool slowly approached each other. At the same time, coolant was sprayed out from the water pipe next to the tool. Under the processing of the glass column, white substances were taken away under the impact of the water flow, and the originally smooth and flat glass columns also changed.
When Wang Bin saw all this, he finally let go of half of his heart. That is, their special glass can indeed be processed using machine tools, and it looks pretty good.
However, it is not yet certain whether this glass can be processed in precision.
Because the material of glass is very different from steel, the performance of their glass is even better.
For example, the hardness is much higher than ordinary glass, so the processing speed is not fast. The machine tool took more than ten minutes before it stopped, 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 a glass screw.
He picked up the warm glass screw due to processing reasons and looked carefully. He found that the screw that had been processed did not look good on the outside, like a mirror. At the same time, he did not see any cracks or gaps on the screw.
Anyway, it is indeed impossible to see with the naked eye that there is something wrong with this screw made from special glass, but Wang Bin's face did not look excited, and of course there was no look of discouragement at all.
He silently picked up the high-precision laser detector that followed the machine in the laboratory, began to detect the screw made of glass, and soon obtained results.
When the test results came out, a smile appeared on Wang Bin's face. The test results showed that the error of any 300 mm length of this glass screw was about 5 microns. In other words, the precision level of this screw processed from glass has reached the level of level three, which is very close to the precision of a second-level screw. And this is still without any polishing and grinding. He believes that if some precision grinding equipment is used for polishing, it is not impossible to reach the level two.
After thinking about it, Wang Bin picked up a glass column and put it into the machining center, and started the machine. After all, a glass screw was processed, so it is still impossible to determine the average accuracy of the ball screws processed from this glass. If it is all around, Wang Bin has to consider whether he should buy some high-precision polishing and grinding equipment.
If the second-level accuracy can be achieved, then the price will be higher when sold to Xu Zhenming.
After all, this precision screw was basically impossible in their era, and 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 small quantities and cannot be produced on a large scale.
And Xu Zhenming's factory is absolutely impossible to get such an accurate screw, and even if he has money, he can't buy it.
Soon, two hours passed by Wang Bin's busyness, and Wang Bin also processed 13 glass screws. The precision level of these glass screws that he just processed reached between 5 and 6 microns, which means that these screws all met the standard of three-level accuracy.
This made Wang Bin breathe a sigh of relief, but Wang Bin also had some worries at this time, that is, the processing speed was too slow, and the fastest speed would take nearly ten minutes to process an 80mm screw, and only six were processed in an hour, which made Wang Bin very annoyed.
After all, in the technology mall, Xu Zhenming's order has a screw with one ton of orders! One ton! How long does it take to process it!
Wang Bin thought about it and began to adjust the control panel of the machine tool again, increasing the processing speed to about five minutes, then put a glass column in it and continued to start the machine tool.
Five minutes passed soon, and the glass column that was previously placed in the machine tool also became a screw.
So Wang Bin immediately took out the screw from the machine tool and then conducted accuracy testing on it. However, since the processing speed was increased by half, the accuracy of the screw could not reach the previous ones, with an error of 8 microns, which means it was just within the third level range. So Wang Bin processed a little more and found that the error was 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 screw processed after re-debugging was finally completed, and Wang Bin naturally tested it again. The results of this detection were much worse than before, with an error of 10 microns. It was obvious that such accuracy could not be considered as level 3, but could only be considered as level 4 accuracy.
However, Wang Bin was still not satisfied with this and began to continue debugging on the machine tool, and continued to shorten the time by half on the original basis. However, after processing and testing, the accuracy error actually reached 15 microns, which means that this accuracy is not even level 4.
Then Wang Bin began to repeatedly debug the machine tool. Finally, the time for processing a screw was set at 110 seconds, and the accuracy of the processing was between 11 and 12 microns, which was just about to reach the level 4 accuracy standard.
After debugging, Wang Bin stopped the machine tool and carefully checked the tools on the machine tool. He even used detection equipment to test these tools. However, Wang Bin's face was not very good. Even if he used diamond tools to process their glass, the wear speed was very fast. Basically, after processing for one or two days, the main tools had to be replaced.
You should know that this is a real diamond precision machining tool! It is not the defective or ordinary diamond tools on the market. Each one costs thousands of dollars at the cheapest price!
