1, according to the semi-finished products, check whether the polished workpiece is missing. All the workpieces that can't be repaired in the luminous stage, such as incomplete polishing of solder joints, rough polishing marks, serious damage of protective film, excessive polishing, excessive fillet, serious polishing at both ends and uneven polishing, should be returned for re-polishing or repair. Irreparable bumps, bumps and large scratches during grinding can repair very fine lines.
2. The main purpose of mirror polishing is to polish the workpiece polished in the previous process, rather than further grinding. In this step, do not rub polishing wax on the covering film on the surface of the workpiece, and do not damage the covering film.
3. Polishing is the last process of mirror polishing. After passing through the mirror, use a clean cotton wheel to rub on the surface of the workpiece, and after the previous process is completed, clean and polish the workpiece. The purpose is to distinguish the weld marks on the surface of the workpiece, and polish the workpiece after waxing and polishing, so that the brightness is 8k higher than the specular reflection, and there is almost no difference between the polished and unpolished parts of the workpiece. Achieve a complete mirror effect
