What is the employment prospect of grinding fitter? Is there room for appreciation? I am a middle school student.

I have been a locksmith 10 for many years. I have been eager to learn since I was a child! I can not only be a fitter, but also do the basic skills of machinery. I also know 3D mechanical drawing, and I can use several mechanical drawing software. I also know electrician, single chip microcomputer PLC computer programming circuit, step servo advanced precise positioning control. But all my skills were not learned at school! I study slowly while working! I taught myself secretly, because I learned it at school. If he teaches you, you will die! As a fitter, it is mainly to consider the manufacturing steps and methods of a workpiece in advance. Drilling is a simple matter, but how to accurately locate and polish the drill bit, different materials have different polishing methods. When drilling, I want you to know how to keep the deviation and how to control the accuracy of the aperture. These are the real skills to be a fitter! I'm a master now! Be respected by many people everywhere! It's no use going to school! You'd better go to the machinery factory to work and study! Not afraid of suffering! You will succeed!
