internship summary

In the practice of locksmith, we know that the main contents of locksmith are scraping, drilling, tapping, sawing, filing, assembly and marking; Understand the structure, classification, selection, filing posture, filing method and quality inspection of archives. First of all, we must get the right gear. It is the key to keep the file moving in a straight line when filing the plane. There are two kinds of filing force: horizontal thrust and vertical pressure. When pushing the file forward, the front hand pressure gradually decreases, and then it decreases when pushing the file to the middle position, and the pressure on both hands is the same. When pushing the file forward, the front hand pressure gradually decreases and then increases. No pressure is applied when the file is returned. This will make it easier for us to file.

Then scrape, grind, drill, hinge, tap and so on. Although it is not very standard, it is the crystallization of our sweat and the result of our two-day struggle.

To tell the truth, locksmith internship is boring. He may have been doing it all morning, but he is repeating an action. He still needs strength, and he needs to do it properly. That is, he took the file back and forth on the workpiece. By noon, his hands were sore and his legs were stiff. However, when he is tired, he can see the teacher personally guiding and demonstrating. He is also sweating and panting. A few days later, looking at my own processing results, I want to say thank you to the teacher who guided us. Turning is not done by numerical control, it requires high manual operation ability.

Before the fitter, I knew that the fitter was hell. Students from other majors have already told me about the hardships of survival of the fittest. And many people regard the broken saw blade as a joke. So I want to win in the middle. When I went there, I was beaten by the master (that is, the master told you that locksmiths are suffering, and everyone should be mentally prepared, and so on). In particular, you are not allowed to go back to using the milling machine! ) and a long group (because there are two people missing in my class, the master has added 20% more time), and we started to work! The first is to saw a piece of iron! Although I was instructed by the master, I was the first person to break the saw blade! And the boys in the same group have already spoken. Depressed! But it doesn't matter. The teacher said nothing to me! Thank god. Maybe I am too unprofessional with the boys in the same group, and we have sawed off several groups, and we are still less than half. However, with my encouragement, the boys in the same group saw the iron instead of the last one. It's good. Followed by scribing and drilling. It's nothing. Because teachers and machines do more. There is nothing special about Tao. The only thing that doesn't suit us is that there is a barbed wire between us and the classmates opposite us, which causes everyone to ask each other when they go in. This problem is more serious. Fortunately, the teacher scattered these people before everyone shared their criminal experiences. The only thing that is a little tired is to flatten your face. At first, I felt very discouraged when I saw how depressed I was, but after listening to the lovely teacher et (it looked very similar but nice), it took three years to draw the disciples, and our hearts were more peaceful. I just crossed the line this morning as if nothing had happened. As soon as the afternoon arrived, we were told to look at the lovely iron along the line drawn in the morning! All the women were frightened. After seeing the teacher, we didn't mean to joke, so we had to go back to the big saw and pull it over! At this time, I realized that human potential is infinite: because of me! A weak woman was the first in our class to saw off the iron! Oh, my god When I saw the ninth wonder of the world I created, I really admired myself! But I made a fatal mistake: the machining allowance left is too large! So I will be depressed for too long. Frustration is a terrible job! I used the remaining 1 day to drop 2 mm steel! Maybe you'll think it's nothing, right Nothing, just frustration! But think about it, I was cutting iron like mud a few days ago, watching iron flowers fly around.
