摘要： The present invention describes a machine to that includes a casing and a toolholder spindle. The machine tool further includes a drive mechanism that drives the toolholder spindle. The drive mechanism includes first and second drive members. The first drive member rotates the spindle about its axis. The second drive member translates the spindle and is screwed onto the spindle in such a way that the spindle advances or reverses as a function of the relative speed of rotation between the first and second drive members. The machine tool also includes a first motor and a second motor. The first motor rotates the first drive member and the second motor rotates the second drive member. The machine too further includes a control unit that controls and adjusts the speed of rotation of the first motor and the second motor independently.
