The invention concerns a process for manufacturing annular work pieces from metal with a profiled cross-section, preferably with external helical gearing, and a rolling facility for carrying out the method. It is proposed that a) forming should be done with two rotating tools; b) the latter should be configured preferably at the same angle to the work piece; c) at least one tool should be fed perpendicularly to the work piece; and d) the die in a mount which is fixed at least axially should rotate about an axis of rotation extending in the tool feed direction. The rolling facility consists of a) two tools (1, 2, 21, 22) which are inclined relative to the work piece (10) preferably at the same angle, at least one tool (1, 2, 21) being capable of displacement in the tool feed direction (12, 20); b) a die (5) with inner gearing which with a closure device forms a closed chamber for the work piece, the die depth matching the width of the teeth; and c) a mount which is fixed at least axially and in which the die (5) is mounted so as to be capable of rotating about an axis extending in the tool feed direction (12, 20).
