Abstract
To produce toothed sections on workpieces, a machine tool has a machine bed, a pivoting element with at least two workpiece spindles arranged thereon and a tool positioning unit with a tool head. The spindles can be pivoted relative to the machine bed about a workpiece spindle pivot axis and each spindle has a workpiece receiver that can be rotatably driven about a rotational axis. The tool head can be linearly moved in three directions relative to the spindles, and can be pivoted about a tool head pivot axis. A bearing element extending in the direction of the workpiece spindle pivot axis, has a free end which is pivotable about the workpiece spindle pivot axis, and is rigidly arranged on the pivoting element. A reinforcing element is fastened to the machine bed. The pivoting element is reinforced about the workpiece spindle pivot axis by the reinforcing element.
