A
honing machine (100) for carrying out
honing operations on boreholes, oriented orthogonally with respect to one another, in a workpiece (102), in particular for
honing processing of cylinder boreholes and a bearing gate borehole in a cylinder
crank casing, comprises a
machine base (110) and a
round table (130) which is arranged on the
machine base and which can rotate about a vertical
round table axis (134) and has a plurality of workpiece receptacles which are arranged offset with respect to one another in a circumferential direction at a radial distance from the
round table axis, in such a way that a workpiece which is held in a workpiece receptacle can be transported successively to different workstations (140, 150, 160, 170) of the honing machine by rotating the round table. At least one of the workstations is a vertical honing
station (150, 170) which has at least one vertical honing unit (180) which has a honing spindle which can move back and forth in the direction of a spindle axis which is oriented parallel to the round table axis, rotatably about said spindle axis. Furthermore, at least one of the workstations is a horizontal honing
station (160) which has at least one horizontal honing unit (300) which has a honing spindle which can move back and forth in the direction of a horizontal spindle axis (304), rotatable about said spindle axis. The horizontal honing unit (300) is or can be positioned with respect to the round table (130) in such a way that the horizontal honing unit assumes a
processing position in which the horizontal spindle axis (304) is oriented radially with respect to the round table axis (134).
