ABSTRACT:
A machine for deburring and fine machining of the tooth flanks of toothed workpieces with a gear-shaped fine machining tool, preferably, a shaving wheel, which is in rolling engagement with a workpiece, comprising a tool spindle, a motor for driving the tool spindle, a workpiece spindle with a clamping device for the workpiece, a motor for driving the workpiece spindle, a sensor correlated with the workpiece spindle for determining the angular position of the teeth of the workpiece relative to the axis of the workpiece and an electronic gear coupling the drive motors of the tool spindle and of the workpiece spindle which, as a function of the signal of the sensor, rotates the fine machining tool and the workpiece such relative to one another that tooth and gap are aligned. In this connection, it is provided that on the tool spindle, in addition to the fine machining tool, at least one toothed deburring tool is fixedly arranged, wherein the rotational position of the deburring tool and of the fine machining tool relative to the tool spindle is defined by an index.
