The former requires the use of coarse abrasive, in order to ensure that the polishing rate to remove the damaged layer of polished, but the polishing damage layer deep; the latter requires the use of the finest materials, so that the polishing damage layer shallow, butpolishing rate is low.
(1) need to use a soft stick or bamboo stick polishing with sandpaper. Polishing of round or spherical, use a soft wooden stick can be better with a round face and spherical curvature. Hard wood like cherry, it is even more applicable to the flat surface of the polishing. The end of the trim strips of wood to steel surface shape to maintain consistent, to avoid the steel surface of the wood (or bamboo) the acute angle contact and cause deep scratches.
(2) when switching to different types of sandpaper, polishing direction should be to transform the 45 degrees -90 degrees, the shadow of this former model sandpaper polished leaving the stripes you can tell the difference. Before the change of the different types of sandpaper, 100% pure cotton dampened with alcohol-based cleaning fluids must be carefully wipe the polished surface, a small gravel to stay on the surface will be destroyed the next polishing work. Sandpaper polishing to change salty diamond abrasive paste polishing, the cleaning process is equally important. Polishing before you proceed, all the particles and kerosene must be completely clean.
(3) in order to avoid abrasions and burns the surface, must be especially careful when polishing with 200 and 500 sandpaper. There was a need to load a light load and the use of two-step polishing method for polishing the surface. Each type of sandpaper polishing, two polishing should be carried out along two different directions, each rotated 45 degrees and -90 degrees between the two directions.
Mechanical polishing is mainly done manually, so polishing technology is still the main influence polishing quality. In addition, the mold material, surface conditions prior to polishing and heat treatment process. High-quality steel is a prerequisite to get a good polishing quality, uneven or characteristics of the steel surface hardness differences tend to produce polished difficult. Steel in a variety of inclusions and pores are not conducive to polishing.
