Abstract
A multistage gear-rolling apparatus of the present invention comprises a roller squeezing apparatus including a roughing roller die and a finishing roller die disposed coaxially and connected in series in an axial direction of said roughing roller die. The roughing roller die is used for carrying out a hot rough-rolling step. The finishing roller die is used for a warm finish-rolling step. Thus, immediately after the hot rough-rolling step, the warm finish-rolling step can be carried out without a reset of workpiece.
