Apparatus for machining plate-shaped or cylindrical workpieces comprising cutting teeth

The invention concerns a device (10) for machining slab-shaped or cylindrical workpieces (70) which are provided with cutting teeth (S), with a machine base (12), a machining device (14) which can be displaced relative to the machine base (12), and a workpiece positioning device (16) which can be displaced relative to the machine base (12), the machining device (14) including a machining bridge (18) which can be displaced relative to the machine base (12) linearly along a first spatial axis (Y1) and a machining arm (20) which can be displaced relative to the machining bridge (18) linearly along a second spatial axis (X1), a machining unit (26) with a machining tool (28) being carried on the machining arm (20) so that it can swivel around a swivelling axis (E1), the swivelling axis (E1) substantially running orthogonally to a plane which is spanned by the first and second spatial axes (Y1, X1), the workpiece positioning device (16) also having a bearing slide (32) which can be displaced relative to the machine base (12) linearly along a third spatial axis (Z1), and a tilting bearing arrangement, in which a workpiece holding arrangement (44) is carried so that it can be tilted around a tilting axis (B1), being provided on the bearing slide (32).
