摘要：
The apparatus and process according to the invention relate to the cold forming by rolling of revolving parts (7).The apparatus comprises two identical milling wheels (9A, 9B) arranged symmetrically with respect to the part (7) to be formed and performing the same rotation movement at speed Vm and progressively moving towards the axis of the part to be formed (X1--X1). The part (7) performs a rotation movement at speed Vp such that Vp=Vm.multidot.N1/N2, N1 being the number of grooves on each wheel (9A, 9B), N2 the number of grooves to be formed on the part (7). An initial setting makes it possible to bring about coincidence between the grooves formed by each of the milling wheels on the part (7).The apparatus and process make it possible to obtain high precision parts.
