Abstract
The single-motored apparatus includes a motor which rotatingly drives a main shaft and a correction shaft, the main shaft in turn rotatingly driving the diamond toolholder, a clutch for coupling and uncoupling the shafts, and a cam/feeler assembly for transforming the rotary movement of the correction shaft into longitudinal movement of the diamond toolholder. When the correction shaft and the main shaft connected by the clutch rotate simultaneously, the diamond toolholder executes solely an angular movement; when the two shafts are uncoupled and only one of the two shafts rotates, the diamond toolholder executes either solely a longitudinal movement or a longitudinal and angular movement at the same time.
