Features:<\/h3>

With the Hunger precision turning process, the valve seat is turned from the inside out with a fine cross 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 cutter.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 self-aligning 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 displaced laterally during boring.<\/p>

Operation:<\/h3>

Operation of the turning tool is remarkably simple.Place the turning tool onto the pilot clamped in the valve guide.If necessary, fix the self-aligning guide with the steady rest or to the clamping fixture.Position the cutter 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 specified seat angle.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\n<\/div>\n

Check Valve Tightness\n<\/h3>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

\"\"Operating Principle: When the trigger button is pressed, the testing device connected to compressed air (approx. 6 bar) generates a vacuum, which is applied to the intake or exhaust port of the valve being tested using an adapter plate. The pressure gauge on the testing device indicates the level of vacuum. If the gauge reading is in the green zone, the valve is tight.View details<\/a><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
