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 sur- face 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 result- in 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 adjust- ment mode. Current drawn by the abrading wheel motor is sensed, and when it is below a preset level a lead screw motor is automa- tically powered to advance the abrading wheel against the disk. When current reaches the preset point, the lead screw motor is stopped.
