    Zou Yongdong half-crouched in front of the control panel, skillfully inputting the workpiece processing control program.  All these data are clearly recorded in his brain and will never be mistaken.  However, after the input was completed, he carefully recalled the program, read it line by line, and confirmed that it was correct before ending the input.  After two months of training on an ordinary lathe, he was transferred to the CNC machine tool operation team at the beginning of the month.  As soon as he arrived here, he felt like a fish returning to the sea.  Due to lack of talent, no matter how hard he worked on ordinary machine tools, he could not catch up with Kong Lingchen.  He has also only learned it for two months, and his movements are so light when he controls the machine tool. Watching him process various workpieces is like an art.  After the master¡¯s evaluation, Kong Lingchen has at least reached the level of a third-level worker.  But no matter how hard Zou Yongdong practices, he is still far away from being a second-level professional.  Therefore, when the CNC machine tool group was set up above, the master immediately reported Zou Yongdong's name.  At first, Zou Yongdong was a little frustrated. He felt that he had been eliminated. Although he did not dare to complain about his master, he was always dissatisfied.  However, he didn¡¯t stay in the CNC group for long before he discovered that he really liked this new processing method.  All workpieces do not require him to control the machine tool with his own hands. He is cautious for fear of making mistakes. Every time he processes a cut, he has to quickly take out various measuring tools and measure repeatedly, fearing that the processing will break again.  Zou Yongdong thought about how he came to the CNC group, and a smile appeared on his face that had been gloomy before.  After the program input was completed, he came to the clamped workpiece, measured various data again, confirmed that there was no slight deviation in the position, and then pressed the CNC start button.  Woo!  The motor makes a low chirping sound and the workpiece rotates rapidly.  Without his control, the knife rest slowly moved up, and tiny bits of iron filings flew out.  He stood aside and observed carefully, cleaning away the remaining iron filings from time to time to check if there were any abnormalities.  After the first knife is processed, the tool holder moves back, changes the tool, and moves up again.  After several times, the processing is completed.  He was an observer during the entire process, and he did not need to do anything. The workpiece processing that used to give him a headache on a manual machine tool was successfully completed, reflecting a bright silver metallic luster under the light.  It¡¯s so easy!  For those of them who have no talent for hands-on work, CNC lathes are a blessing, allowing them to complete workpiece processing with quality and quantity like a skilled worker.  As for those dazzling programs, Zou Yongdong is not afraid at all.  His memory is very good. He quickly memorizes various control instructions that others cannot memorize, and can use them flexibly in a short period of time.  With his early experience in operating manual machine tools, these seemingly boring functions turned into vivid processing scenes in his mind. The two sides corresponded to each other, and he learned it even faster.  While others were still struggling to memorize each line of instructions and understand their meaning, he had already officially started.  Moreover, the one assigned to him was the first CNC lathe modified by the commander himself. Its processing accuracy was also the highest among all later modified lathes, and no one has ever been able to surpass it!  The workpieces he is processing now are no longer the standard demonstration parts during training, but real mechanical parts, with design drawings and tooling drawings, and every indicator is listed in detail.  The workpiece is also very complicated. If it were him in the past, he would never dare to process it, and he would not have the courage to even try it.  But with the help of CNC lathes, as long as he splits each workpiece processing process into different processes, then uses function calculations, selects the correct tool, and does the measurement work, it is actually not difficult to process complex workpieces.  However, since there are more than ten or even dozens of processes, frequent tool changes are inevitable.  After completing this stage of the process, Zou Yongdong stopped the car, removed the clamped tools, and then selected four other tools according to the requirements of the subsequent processes.  He was very careful in the process of re-buffing the knives, comparing and measuring repeatedly, concentrating on it and not daring to relax at all.  Why the accuracy of mechanical processing is not high? The processing accuracy, vibration and deformation of the machine tool itself are certainly the main reasons.  In a long process, a workpiece is moved multiple times and lathes and cutting tools are replaced, which is also the direct cause of the decline in accuracy.  Any mistake in any process, if the reserve margin is insufficient, may cause the workpiece to be scrapped, and all the previous processes will be wiped out.  The machining accuracy of CNC lathes is actually not much higher than that of manual machining.  The same machine tools that are not very precise can usually process high-precision parts that exceed their own accuracy in the hands of experienced masters. ? ? ? ? ? ? ? ?Because the entire processing stroke of the CNC machine tool is carried out under the command of the control system, there will be no hand shaking or misoperation like manual work, ensuring the stability of the processing process.  Each step forward and backward is accurately realized under the control of a stepper motor, and there will never be any visual misjudgment like manual work.  As long as the program is entered correctly and no emergencies such as circuit failures occur, there will be absolutely no mistakes in the machining process.  For example, for the same machine tool, the normal accuracy is fifty microns.  A level 6 worker may use it to process parts of 40 microns, a level 7 worker may use it to process parts of 35 microns, and an eighth level worker may use it to increase the accuracy to 20 microns, and then use it to process parts of 35 microns.  Through manual polishing, its accuracy is improved to one micron!  But their processing process will be very long.  A Level 6 worker may take a whole day to process this precision component, while a Level 7 worker may need more than ten days or even a month.  As for ultra-precision parts with an accuracy of one micron, even if it is an eighth-level worker, it may take several months, or even a year or two to complete.  The CNC machine tool controlled by Zou Yongdong and modified by Guan Fei himself has an average accuracy of about 212 microns.  In other words, if there are no other factors and the same control program is used, the accuracy of the parts processed by this lathe will only be 212 microns: it will not be much higher, but it will not be much lower, and the error will not exceed  Two microns!  As for the time required for processing, it only takes a few minutes!  And it¡¯s not just that this one part takes a few minutes. The same parts in the same process, each put on, only take a few minutes to be processed with the same accuracy.  This is the value of CNC machine tools!  Zou Yongdong successfully completed the processing of this part. After parking the machine, he happily removed it from the chuck and placed it aside.  At the same time, he looked at the medium-sized machine tool a few meters away.  That is a manual lathe without CNC improvements, and its controller is Guan Fei!  From Zou Yongdong¡¯s point of view, Guan Fei is holding the huge tool holder with his right hand, his expression is extremely focused, and he seems not to notice that he is watching from the side, and all his eyes are focused on the parts being processed.  The parts Guan Fei is processing are much larger than Zou Yongdong's small lathe, with a diameter of more than ten centimeters and a length of two meters.  Zou Yongdong knows that the larger the machine tool, the heavier the tool structure and the more difficult it is to control.  He can¡¯t even use small general-purpose machine tools well, so asking him to operate medium-sized machine tools is just a joke.  Not to mention the extremely high scrap rate, it¡¯s hard to say whether it will hurt yourself.  But here, he saw that Guan Fei's control was always so stable, and his knife advance and retreat could be said to be just right.  This kind of stability is acceptable once or twice, but if it happens like this every time, it can only be said to be terrible.  What particularly shocked him was that Guan Fei had been so stable for more than half a month.  When he first came here and started actually operating the CNC lathe, he saw Guan Fei here every afternoon, controlling the medium-sized machine tool and processing seemingly complex parts.  In the evening, when other workers have gone off work, Guan Fei is still here, working overtime and busy.  Several times, he deliberately ran to look at it at night and found that the lights in the workshop were still on.  One time when he couldn't sleep at one o'clock, he accidentally walked here and still saw Guan Fei burning the midnight oil, processing various parts that seemed to be endless.  Because Guan Fei was in the army in the morning, driven by curiosity, he went to peek at the tooling drawings and measured the processed parts. He was shocked to find that the processing accuracy of these parts was so high that it was beyond his ability.  expectations - the average accuracy reaches about ten microns, and the highest accuracy even reaches seven microns!  He really couldn¡¯t imagine how Guan Fei could achieve such high precision by operating it entirely by hand.  Could it be said that capable people can really do what ordinary people cannot?  Zou Yongdong watched quietly for a while, confirming that Guan Fei's hands were still so steady and his movements were still so relaxed and natural, neither fast nor slow, but extremely efficient.  Although it is manual, its processing speed is not much slower than my own CNC lathe.  Considering the size difference of the processed parts, Guan Fei¡¯s processing speed is actually much faster than him!  There is really no comparison between these people!  Speaking of this, he turned his attention to the other end of the workshop.  Over there, there is also a group of people working nervously. They are generally quiet, but from time to time a fierce quarrel breaks out.  Over there is the debugger who temporarily borrowed the Seiko workshop to assemble the CNC lathe.  He also knows one of them. Maybe he is not the only one who knows him. He also knows the military commander.Several people have seen him before. He used to work as a teller in a bank.  From the bankbook's name badge, I found out that his name was Xie Guoping.  "We know each other well. Since he arrived here, he has not had any dealings with that group of people over there.  Those people were very proud.  They considered themselves to be senior technicians who installed and debugged precision lathes, and looked down upon him, a young worker who was still in the learning period. There was basically no communication between the two parties.  ¡°But Zou Yongdong admitted that they do have the capital to be proud.  It was through their hands that general lathes were converted into CNC lathes, and the accuracy was at least doubled.  Although their abilities are far inferior to Guan Fei, no one in the military division dares to think that they are stronger than Guan Fei. Such an improvement in accuracy is already something to be proud of.  Their treatment is also very enviable to Zou Yongdong.  Everyone has the same salary based on seniority, but the salary for an assembly and debugging position is 30 yuan, which is a full 12 yuan higher than the salary of an ordinary worker.  At the same time, their performance pay is also very high. For every machine tool installed and debugged, their superiors will reward them 50 yuan.  Under this kind of stimulation, they risked their lives.  The last time I heard them chat, twenty of them completed the installation and commissioning of 96 lathes in two months, and received a reward of 4,800 yuan!  This is amazing. With such a high reward, each person can get an average of 240 yuan!  That¡¯s an extra $120 per month!  Moreover, they were not evenly distributed, they were divided into groups of five, and were distributed according to the quantity and quality completed by each group. I heard that the highest group received nearly 400 yuan each!  They are not satisfied with this.  As mentioned above, after the construction of the machine tool factory is completed and they are moved in, they are allowed to form their own installation teams.  In addition to one debugger, each group will also be assigned ten assemblers to assist them in their work. By then, those with higher skills will be able to earn more.  So these days, Zou Yongdong found that these people were like being possessed every day, talking around the lathe and talking non-stop.  In order to improve their assembly skills, they tried every means to exercise their hand sensitivity and visual observation.  Even if we met in the cafeteria, the other person would be talking about various assembly precautions and would be absent-minded while eating.  ¡°Forget it, other people are other people¡¯s business. Instead of envying others, it¡¯s better to do your own work well.  Zou Yongdong took this opportunity to rest for a while and turned his attention to his work again.  He also has a performance award!  No matter what job position, as long as you do it well, he believes that it will be good!  There is definitely no such environment in China, but here, there are military divisions that create various favorable conditions for everyone to use their talents. He firmly believes that as long as it is gold, he will always shine!  Maybe in the future, my achievements will not be weaker than yours, maybe even stronger!  With a smile on his face, Zou Yongdong half-bent over, focusing on the rotation of the workpiece, and continued working.  (PS: After a few days, people become mentally exhausted, and the quality of what they write is not high. The author is not an energetic person, and his ability to work continuously for a long time is relatively poor. In order to successfully complete this book, he decided to take a rest every Tuesday in the future.  One day. Today¡¯s chapter has been written, so let¡¯s take a day off tomorrow. I hope you will understand)
