A flow-forming machine and method for forming a final part having helical splines. The flow forming machine (10) is provided with a stripper plate (12) for removing the final part (4) having the helical splines therein from the mandrel (14) and a thrust bearing (16) is located between the stripper plate (12) and the final part (4) during stripping of the final part (4) from the mandrel (14) to allow relative motion between the stripper plate (12) and the final part (4) to successfully strip the final part (4) from the mandrel (14) without damaging and while maintaining the integrity of the helical splines of the final part (4). The ejector driver (32) and mandrel (14) may be rotated in either direction to help in successfully stripping the final part (4) from the mandrel (14).
