Machine for deburring and fine machining of tooth flanks of toothed workpieces

A machine for deburring and fine machining of the tooth flanks of toothed workpieces by means of a gear wheel-shaped fine machining tool which is in rolling engagement with a workpiece, said machine comprising:

• a machine frame;
• a first slide moveably supported on the machine frame and configured to be driven for movements along a first axis X;
• a second slide moveably supported on the first slide and configured to be driven for movements along a second axis Z which is positioned at a right angle to the first axis X;
• a tool head which is connected pivotably to the second slide and configured to be pivoted for adjusting the axis crossing angle between the fine machining tool and the workpiece about a third axis A which is parallel to the first axis X;
• a motor arranged on the tool head for driving a tool spindle;
• a workpiece spindle with a clamping device for clamping 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;
• the drive motor of the tool spindle and the drive motor of the workpiece spindle being coupled electronically to rotate, as a function of a signal of the sensor, the fine machining tool and the workpiece relative to one another such that tooth and gap are aligned;
• wherein on the tool spindle, in addition to the fine machining tool, at least one toothed deburring tool for deburring tooth end faces is fixedly arranged and wherein the rotational position of the deburring tool and of the fine machining tool relative to the tool spindle is defined by an index.
