APPARATUS FOR DRESSING INSIDE DIAMETER SAWS

摘要

Apparatus (10) for dressing the cutting surfaces around a central opening of an annular inside diameter saw (S). The apparatus includes a base (12) and a shaft (14) mounted on the base (12) for rotation on a longitudinal axis (L) of the shaft (14). The shaft (14) is adapted to be positioned adjacent the central opening of the saw (S). The apparatus (10) also includes a fixture (16) mounted on the shaft (14) for holding a dressing stone (D) in the central opening of the saw (S). In addition, the apparatus includes a motor (18) for rotating the shaft (14) to move the dressing stone (D) held by the fixture (16) along an arc (A) centered on the longitudinal axis (L) of the shaft (14) into engagement with the cutting surfaces of the saw (S) when the saw (S) is rotating thereby to remove deposits from the cutting surfaces of the saw (S).
