Dry polishing is a process commonly used for surface treatment of metal products. It can also be used for materials such as jade to improve the appearance texture and gloss of the product. The following is its impact on the tolerance of different materials:
1. Stainless steel: In the polishing of some stainless steel precision parts, the tolerance can be controlled within plus or minus 0.005mm. If it is a stainless steel workpiece with a complex shape, or the polishing parameters are not set properly, there may be a large change in local tolerance, such as micro-deformation of thin walls due to uneven force.
2. Zinc alloy, aluminum alloy, zinc alloy, and aluminum alloy are relatively soft in texture. If the abrasive is not selected properly or the process parameters are unreasonable, excessive wear is likely to occur, resulting in tolerances beyond the expected range. By selecting suitable plant abrasives and controlling parameters such as polishing time and speed, the appearance size tolerance can be controlled within plus or minus 0.02mm.
3. Brass: Brass has good ductility and toughness, and the polishing process has relatively little effect on its tolerance. In the fine grinding and polishing stage, as long as the process requirements are strictly followed, the tolerance can be controlled within plus or minus 0.01mm.
3. Jade material
Jade has a high hardness but is brittle. If the centrifugal force is too large or the abrasive is not suitable during polishing, it is easy to cause cracks or edge collapse on the surface of the jade, thus affecting the tolerance. For jade with lower hardness, appropriate polishing parameters can better control the tolerance, and the external dimension tolerance can be controlled within plus or minus 0.05mm.
