The round tube polishing machine is mainly used for surface polishing of aluminum tubes, iron tubes, copper tubes and steel tubes

Effect of different hardness on polishing process. The hardness increases the difficulty of polishing, and the roughness after polishing is also reduced. As the hardness increases, the polishing time required to achieve a lower roughness increases accordingly.

The surface condition of the workpiece affects the polishing process. During the process of steel processing and crushing, the surface layer may be damaged due to heat, internal stress or other factors, and improper cutting parameters will affect the polishing effect. The hardened layer is harder than the base material and must be removed. Therefore, it is best to add a rough grinding process to completely remove the damaged surface layer and form an average rough metal surface, which provides a good foundation for the polishing process of the round tube polishing machine.
