Abstract
A machine tool for machining a piece has an axis of rotation A, and includes a no-force precision machining unit to machine the piece, a first spindle, a first clamping device clamping the piece and mounting it on the first spindle, and a machine parameters guidance system. The guidance system guides a controller for the machining unit to control a first machining phase of the piece on the first spindle programmed to obtain a blank mounted on the first spindle, with target dimensions are 0.5% to 20% greater than the final dimensions, then to modify the machining parameters to control, starting from the blank on the first spindle, a second machining phase to remove a quantity of material to obtain the finished piece, with the final dimensions and a roughness of less than 40 nm. A method for machining a piece using such a machine tool is also described.
