  • Patent number: 4825596
    Abstract: A method and apparatus for surfacing the face of a clutch flywheel or other friction disk achieves a surface pattern which promotes proper wearing-in of the flywheel or disk and of a friction disk or pad which engages the disk. The abrasive surface of a rotating abrading wheel is applied to a disk rotating in the same angular direction as that of the abrading wheel. A rotating cup-shaped abrading wheel is tilted slightly with respect to the frictional contact surface of the disk so that only one portion of the wheel engages the disk at a time resulting in a resurface pattern of lines that essentially do not cross over each other. Advancement of the abrading wheel against the flywheel or disk may be automatically controlled in fine adjustment mode. Current drawn by the abrading wheel motor is sensed, and when it is below a preset level a lead screw motor is automatically powered to advance the abrading wheel against the disk. When current reaches the preset point, the lead screw motor is stopped.
