This paper presents a numerical simulation and experimental study on profile-rolling process for micro-teeth components. The target component was made of AISI 304 stainless steel with 6.0 mm outer diameter, and its number of teeth was 25. Three raw material rods with different diameters 5.6 mm, 6.0 mm, and 6.4 mm were investigated in the finite-element simulation. The spindle speed of the rolls was 60 rpm, and the material forward speed was 1.8 mm/s, which were reasonably compatible with the practical profile-rolling conditions. The simulation results showed that the different numbers of teeth were produced by employing different diameters of raw materials. Only the rod with the 6.0 mm diameter could be rolled into the near desired shape. Experimental verification was also undertaken. The numerical simulation was found to be in good agreement with the measured profile of the actual rolled component. The microstructure of the material after rolling was improved also as the hardness of the teeth was 40% higher than that of the core.
