A device for machining a cylindrical bore, the device comprising:
- a base member having a receiving end configured to be received in a receptacle of a machine tool;
- a first machining tool with at least one geometrically undefined cutter;
- a second machining tool with at least one geometrically defined cutter;
- a first pressure rod acting on the first machining tool with geometrically undefined cutter, wherein the first pressure rod is coaxially arranged to the base member;
- a second pressure rod acting on the second machining tool with geometrically defined cutter, wherein the second pressure rod is coaxially arranged to the base member;
- wherein the second machining tool with at least one geometrically defined cutter is embodied as a precision turning tool or a fine boring tool;
- wherein the second machining tool with at least one geometrically defined cutter is arranged at an end of the base member opposite the receiving end.
The machine tool according to 30, comprising a second electromechanical feed device acting on the second machining tool with at least one geometrically defined cutter, wherein the first feed device moves the first pressure rod and the second feed device moves the second pressure rod relative to the base member in order to feed the first and second machining tools.
