Abstract
A unique method and apparatus for making a score cut on a metal object with a previously used abrasive cutting wheel, worn down from a new, larger diameter wheel to allow use of worn cutting wheels and to improve the ratio of cross-sectional area of metal material cut to cross-sectional area of wheel used. Another feature is the use of a hydraulic bearing for reducing friction between the object rotating chuck stands and the track on which the stands are moved by simultaneously flushing the abrasive particles from the track. In one embodiment, the flushing material is recycled to replenish the coolant reservoir fluid loss through evaporation.
