Features:

The machine is fitted with two motors providing a smooth cutting action. The operating voltage supplied to the motors by a compact power supply unit is of the low voltage type to eliminate electric hazards.
The exchangeable adapter head with the built-in slideway for cutting tool travel ensures a precise seat angle eliminating faulty setting operations.
A refacing head for face turning is available in addition to the valve reseat facing heads for the popular seat angles.
A special groove cutting head is available for cutting a groove into the valve seat ring so that the hook elements of a puller can grip the valve seat ring for removing the valve seat ring from the cylinder head.
Roundness, concentricity and surface finish of the refaced valve seat are within manufacturers’ specifications or even better.

Handling:

Setup is fast and easy.
First, lock the pilot with mounted supporting spider in the valve guide. Then, lower the machine over the pilot and position the cutting tool in front of the inner edge of the valve seat.
Connect the machine to the separate power supply unit Turn micrometer downfeed to set the desired depth of cut.
Refacing is automatic. Pressing one button is enough to start the refacing pass. Two to three passes will restore the valve seat to the original condition.
