The invention relates to a machine tool for introducing bores into a workpiece, said machine tool comprising a machine frame, a drilling tool holder which is arranged on the machine frame and has at least one tool spindle, and a workpiece carrier which is arranged on the machine frame, the boring tool holder and the workpiece carrier being displaceable in relation to each other in a direction of displacement. A longitudinal direction of the at least one tool spindle is oriented transversally in relation to a horizontal plane, and the drilling tool holder is arranged on the machine frame in such a way that it can be pivoted in relation to the workpiece carrier, so that inclined bores can be introduced into the workpiece.

Machine tool

There is disclosed a machine tool for machining bores having a large axial length and a boring tool especially suited for a machine tool of this kind in which a boring bar holding at least one tool lip is supported by a steady adapted to be connected to the boring bar via a coupling By the steady the radial excursion of the boring bar during the machining process is reduced to a minimum.

In order to improve a device for the non-circular machining of workpieces comprising a machine frame, a workpiece spindle held on the machine frame and operated as C-axis for a workpiece to be machined, a Z-slide displaceable on the machine frame in the Z-direction in relation to the workpiece spindle and having a Z-axis drive, an X-axis drive in the form of a linear motor arranged on the Z-slide for advancing a tool in the X-direction towards the workpiece, and a numerical control system for activating the X-axis drive in correlation with the rotation of the workpiece spindle, such that more precise work results are obtained, it is proposed that the linear motor serving as X-axis drive be a three-phase asynchronous linear motor with a primary part fixedly arranged in the X-direction on the Z-slide and a secondary part movable relative to the primary part.
