Honing apparatus

Apparatus for honing a bore in a workpiece, which bore is aligned horizontally during machining for honing a crank bore in a crankcase, comprising:

• an apparatus base;
• a turntable which is arranged on the apparatus base and has a plurality of workpiece receptacles, the turntable being rotatable about a vertical turntable axis and the workpiece receptacles being arranged such that a workpiece received in a workpiece receptacle can be transported to different work stations of the apparatus by a rotary movement of the turntable about the turntable axis;
• at least one loading station for loading and unloading the workpiece receptacles, the at least one loading station forming a work station of the apparatus;
• at least one honing station having a horizontal honing unit and having a displacement device for displacing the horizontal honing unit relative to the turntable, the at least one honing station forming a work station of the apparatus, and a honing tool comprising cutting means being coupled or couplable to the horizontal honing unit such that the honing tool can be rotated about a horizontal spindle axis and moved back and forth in a direction parallel to the spindle axis;
• at least one tool magazine for receiving a plurality of honing tools;
• characterized in that
• the at least one tool magazine is fixed in an immovable manner at least with respect to translational movements, the at least one tool magazine being positioned or positionable with respect to the at least one honing station such that the at least one tool magazine assumes a tool-changing position in which relative movements between the at least one tool magazine and the horizontal honing unit of the at least one honing station, which movements are required for a tool change, in order to place a honing tool in the at least one tool magazine and/or in order to receive a honing tool from the tool magazine, can be provided by displacement movements of the horizontal honing unit by means of a displacement device.
