The general process of polishing is to use a fine file to the surface of the first light, and then use the coarse stone rasp the place where the shine, the file filing lines worn away, and then use a fine stone to oil oil lines Mill to, and then the fine metallographic sandpaper to oil where the oil over. This is the mold polishing process a few years ago the whole process. Now with an ultrasonic polisher, used polishing paste and abrasive paste. Some of the original process to be polished by hand has been polished with a machine. Efficiency has improved a lot, clear also improved a lot.
