ABSTRACT:
A device for resurfacing the valve face of a poppet valve in which the pressure between a cutting surface and the valve face is controllable by the operator during the surfacing operation. A bearing case is rotatably attached to a base which is attached to a pair of gripping blocks. A cutting head is rotatably mounted on the bearing case. The cutting head, the bearing case, the base and the gripping blocks define a passage into which a valve stem is inserted. The gripping blocks are clamped in a vise which in turn clamps the valve stem in the device. When the bearing case is rotated, pressure between the cutting surface and the valve face is increased. When the cutting head is rotated, the valve face is resurfaced.
