In order to obtain a rotator with low surface roughness and variable radii, based on the technology of laser cladding manufacturing process with coaxial inside-beam powder feeding, the advantages of coaxial inside-beam power feeding accumulation and the influence of the posture, increment in z axis (z) and laser power of the laser head on the surface roughness were analyzed theoretically and verified experimentally. In the accumulation process, laser head was kept perpendicular to the molten surface, z and laser power were effectively controlled. Finally, a fine rotator was obtained with low roughness, i.e.,Ra=0.497m~2.163m;Rz=1.992m~7.447m. Experimental results show that this method is applicable for laser accumulation on vertical surfaces and the molding parts have lower roughness.
