What fGenerally speaking, the current Polishing machine is mainly used for polishing the surface of aluminum tubes, iron pipes, copper pipes and steel pipes, etc. It has the characteristics of high efficiency and good effect, and thus affects the polishing quality of the circular tube. What are the general factors?
Because mechanical polishing is mainly done manually, human polishing technology is still the main reason for the quality of polishing. In addition, it is related to the mold material and the surface condition before polishing, as well as the heat treatment process. High-quality steel is a prerequisite for good polishing quality. If the surface hardness of the steel is uneven or the characteristics are different, it will often cause polishing difficulties. Various inclusions and pores in the steel are not conducive to the polishing of the round tube polishing machine.
The different hardness of the material will also have an effect on the polishing process. The increased hardness will increase the difficulty of grinding, but the roughness after polishing will also decrease. Because of the increased hardness, the polishing time required to achieve lower roughness is also correspondingly increased, while the hardness is increased and the possibility of over-polishing is correspondingly reduced.
The surface condition of the workpiece also has an effect on the polishing process. In the process of cutting the machining of the steel, the surface layer is damaged by heat, internal stress and other factors, and the cutting effect is easily affected by improper cutting parameters. The surface after EDM machining is more difficult to grind the surface after ordinary machining and heat treatment, so the fine gauge quasi-electric spark should be used before the end of EDM, otherwise the surface may form a hardened thin layer.
