  • Lapping system and method for lapping a valve face
    Patent number: 8585464
    Abstract: A lapping system includes a shaft. A stabilizing member is coupled to the shaft. A lapping tool is coupled to the shaft and spaced apart on the shaft from the stabilizing member. An adjustable force device is coupled to the shaft, the stabilizing member, and the lapping tool. The adjustable force device is operable to be adjusted in order to cause the stabilizing member to support at least some of the weight of the lapping tool. The lapping system may be coupled to a valve body having a valve face to ensure alignment of the lapping tool and the valve face while providing a controlled, vertical force from the lapping tool to the valve face.
