Precision hardware can be opened according to production needs. After that, some small parts can be cut by gongs or CNC processing. However, precision hardware must be opened for punching, and then welded, then sanded and sprayed. It’s done. It should be noted that the small parts also need to be plated or oil sprayed on the surface after grinding. There are many situations of batch processing of precision hardware processing parts, so the manufacturing methods, cycles and operating specifications and processes of precision metal processing are different. Next, we will introduce precision metal processing technology and operating specifications for our field workers.
