Estimating the term…
A tool post including a body extending according to an axis A-A, the latter including, at one of its ends, a base for fastening to a numerically-controlled machine tool and, at the other end, a head movable in rotation, the head including at least two tool-holder spindles, each being intended to receive a cutting tool in engagement, the spindles occupying, depending on the angular position of the head, a working position in which they are intended to carry out a machining operation on a workpiece held in position in a fitting or a standby position in which they are withdrawn from the workpiece, each of the spindles being configured to be controlled independently of the other in order to immobilise or drive in rotation the cutting tool carried thereby, irrespective of the position it occupies.
