An apparatus for manufacturing a body provided at one end with a surface of revolution. The axis of the apparatus is aligned with a predetermined longitudinal axis of the body. The apparatus including a mechanism for the compensation of the oscillations of the free end of the body. The apparatus is disposed around an assembly comprising a mandrel at the end of a flexible rotatable shaft, the mechanism including a bearing surrounding a component of the assembly. A plurality of means generating oscillating mechanical forces against the bearing means are guided by signals derived from rotation of the shaft to provide phase and amplitude synchronization and compensation of the oscillations of the free end of the body.
