ABSTRACT:
An apparatus and method for polishing combustion engine valves. The machine includes a rotating deburring wheel for on contact with the valve stem and a regulating surface which provides support and applies a rotational force to the valve stem. A pair of guide blades and a guide plate cooperate with the regulating surface to contain the valve stem when contacted by the deburring wheel. The guide blades are positioned at an angle with respect to the axis of rotation of the regulating surface to bias the valve in an inward direction against the guide plate during valve rotation. The machine further includes the use of a unique pivot point for the deburring wheel support so the deburring wheel contacts the valve stem approximately above the valve stem centerline regardless of valve stem diameter or variations in the diameter of the deburring wheel.
