Abstract

The bar is machined to the desired longitudinal and/or circumferential profile by rotary tools (3) carried by a main plate (5) rotated on the chassis (20), the tools being connected to the plate by tool supports (4) able to move radially on this plate, and depending on the desired profile, a radial movement of the tool supports is commanded according to the axial position of the bar with respect to the chassis and/or to the circumferential position of the tools with respect to the bar. In order to command said radial movement, a secondary plate (6) is rotated coaxial with the main plate (5), this secondary plate (6) comprising means (42) of actuating the tool supports (4), which are arranged in such a way that the position of the tool supports is dependent on the relative angular position between the main plate and the secondary plate and, in order to adjust the radial position of the tools permanently during rotation of the main plate (5), said relative angular position is altered.
