Abstract
An abrasive cutting system has an abrasive cutting wheel, a holder for the object to be cut, and means for advancing and retracting the wheel and holder relative to each other. Preferably, the advancing and retracting means is connected to the holder, while the cutting wheel is stationary except for its rotary motion. In accordance with this invention, apparatus for automatically, intermittently advancing the wheel and holder toward each other while the wheel is cutting the object is provided. This automatic, intermittent advancement provides significant improvements over a uniform rate of advancement.
