Tool system

A method for machining a workpiece, the method comprising:

• providing a tool system including:
• a machine-proximal shank configured to be insertable into a driven tool receptacle, the machine-proximal shank containing a device for transmitting a rotating movement to be acquired from the driven tool receptacle;
• a tool-proximal shank configured as a tool holder or configured to have a tool holder releasably connected to the tool-proximal shank;
• a gear mechanism disposed between the machine-proximal shank and the tool-proximal shank, the gear mechanism configured to transmit a rotating movement transmitted by the device to the tool-proximal shank with a reduction;
• and
• at least one insert seat configured on the tool holder, the at least one insert seat receiving an interchangeable cutting insert in the at least one insert seat, the insert seat configured on an end face of the tool holder extending transversely to a longitudinal axis of the tool holder;
• the at least one insert seat having an end face extending transversely to the longitudinal axis of the tool holder;
• the tool-proximal shank and the longitudinal axis of the tool holder coinciding or at least running parallel to one another and the tool holder being rotatable or pivotable about a longitudinal axis of the tool-proximal shank;
• the interchangeable cutting insert including at least one cutting corner having an upper side configured as a rake face and a lower side configured as a bearing face;
• rotating the workpiece about a workpiece axis;
• machining a surface of the workpiece using the cutting insert with the upper side of the cutting insert configured as the rake face substantially perpendicular to the longitudinal axis of the tool holder;
• and
• changing an alignment of the cutting insert and transmitting a rotating movement from the device for transmitting the rotating movement to the tool holder carrying the cutting insert with a reduction by the gear mechanism.
