Abstract
A scratch removal tool that includes a motor, a housing, a rotatable shaft operably coupled to the motor and movable in an axial direction along a length of the shaft, and a head assembly. The head assembly includes a shroud member having an open end, a pad member, a slurry input, a slurry output, and a seal member. The pad member is positioned within the shroud and mounted to the shaft. Rotation of the shaft rotates the pad member. Axial movement of the shaft moves the pad member relative to the open end of the shroud. The slurry input and slurry are in fluid communication with the pad member. The seal member is positioned at the open end of the shroud.
