Abstract
A machine tool having a drivetrain, which includes a tool shaft rotatably mounted on a drive support by means of a bearing assembly and a tool holder arranged on the tool shaft, wherein the tool shaft is rotationally drivable by a drive motor of the machine tool around a rotational axis, and wherein a balancing device is arranged on the tool shaft, which includes a guide body having at least one orbital path extending around the rotational axis and at least one balancing body movably mounted in the orbital path.

A machine tool, having a drivetrain, which includes a tool shaft rotatably mounted on a drive support by means of a bearing assembly and a tool holder, arranged on the tool shaft, for a disk-like working tool, wherein the tool shaft is rotationally drivable by a drive motor of the machine tool around a rotational axis, and wherein a balancing device is arranged on the tool shaft, which includes a guide body having at least one orbital path extending around the rotational axis and at least one balancing body movably mounted in the orbital path, and wherein the at least one orbital path arranged on the guide body comprises a first orbital path having a first radial distance to the rotational axis and at least one second orbital path, which is at a longitudinal distance with respect to the rotational axis in relation to the first orbital path, and which has a greater second radial distance to the rotational axis than the first radial distance and is separated from the first orbital path, so that the balancing bodies arranged in the respective orbital path are held so they are non-adjustable between the orbital paths and/or in a cage like manner in their respective orbital path.
