Features:

With the Hunger precision turning process, the valve seat is turned from the inside out with a fine facing feed.

A worm gear located in the gear head of the turning tool ensures a fine feed of 0.05 mm per revolution of the lathe tool.
The direction of the feed movement is determined by a guide in the replaceable boring head of the turning tool, which is inclined according to the seat angle.
A pilot clamped into the valve guide centers the turning tool.
For additional support of the turning tool centered and guided by the pilot, a pendulum guide is provided below the hand crank, which can be fixed with a steady rest or to the cylinder head clamping fixture available from Hunger, so that the turning tool cannot be pushed sideways during the turning process.

Handling:

Handling the turning tool is remarkably simple.
Place the turning tool onto the pilot clamped in the valve guide.
If necessary, fix the pendulum guide with the steady rest or to the clamping fixture.
Position the lathe tool in front of the inner edge of the valve seat using the quick adjustment.
Set the depth of cut using the feed scale.
Rotate the turning tool around the pilot using the hand crank while holding the feed actuator.
The valve seat is thus inevitably turned concentric to the valve guide at the correct seat angle.
