Effect of polishing process on flagpole
Because the application skills of polishing have not yet reached a very high level, the workpiece to be polished and the polishing material itself are still the primary factors affecting the quality of polishing. High-quality workpieces to be polished are prerequisites for excellent polishing results. If there are debris in the workpiece to be polished, then even the best polishing material will not reach the desired polishing effect.
The effect of the polishing process on the flagpole:
Because polishing is still done manually, the polishing material skills are still the number one cause of the quality of the polishing material. In addition, it is related to the mold material, the appearance of the material before polishing, the heat treatment process, and the like. Good steel is a prerequisite for the quality of outstanding polishing materials. If the hardness of the flag steel is uneven or the characteristics are different, it is often difficult to polish the material. Various inclusions and pores in the flag steel are not conducive to polishing materials.
During the machining process, the surface layer may be damaged by heat, internal stress or other factors, and improper cutting may affect the effect of the polishing material. The appearance after EDM is more difficult to grind than the general mechanical or heat-treated appearance. Therefore, the EDM should be cleaned before the EDM is finished, otherwise the appearance will form a hardened thin layer. If the EDM is not properly calibrated, the depth of the heat affected layer can reach 0.4mm. The hardness of the hardened layer is higher than the hardness of the substrate and should be removed in time. Therefore, a rough grinding process can be added to completely remove the damaged outer surface layer to form an average rough metal surface, which provides an excellent basis for polishing material processing.
Polishing will also be affected by the hardness of the polished workpiece. The hardness will be different, and the polishing effect of the polishing material will also be affected. The higher the hardness of the workpiece to be polished, the greater the consumption of the polishing material, but the roughness of the polishing material will be reduced. When the lower roughness is reached, the polishing time of the polishing material is correspondingly increased, and the probability of occurrence of over-polishing is also greatly reduced.
