Abstract
A machining device including a framework, a transmission shaft and a drive mechanism including a rotation member for driving the shaft in rotation about its axis, a drive member in helical connection with the shaft to drive the translation thereof along its axis with a feed movement, according to the relative rotational speed of the rotation and drive members. The drive member is mounted with the ability to effect translational movement with respect to the framework along the axis and is positioned between the rotation member and an end for coupling of the shaft to a cutting tool, while an electromechanical actuator is mounted in a fixed frame of reference associated with the framework in front of the drive member to which it can be coupled in order to cause it to oscillate translationally so as to superpose an axial oscillation component with the feed movement.
