An abrasive grinding machine is particularly suited for the removal of slag surrounding the edges of metal workpieces torch-cut from flat stock. The grinding machine includes a longitudinal conveyor that is tilted about a longitudinal axis so that one longitudinal edge is lower than the lower. A fence is positioned along the lower edge to retain and guide workpieces as they are carried forward by the conveyor. A grinding head consists of an endless grinding belt carried and driven by upper and lower parallel rollers. The lower contact roller is positioned in spaced relation to the upper flight of the conveyor. The contact roller is positioned with its rotational axis at a predetermined acute angle measured clockwise from the forward line of conveyor movement. The rollers are driven so that the grinding belt moves toward the fence, creating a major component of movement perpendicularly toward the fence and a minor component of movement in the direction of conveyor belt movement. In an alternative embodiment, the contact roller is positioned at an acute angle that is measured counterclockwise from the line of forward conveyor movement. This produces a major component of movement perpendicularly toward the fence and a minor component of movement opposite the direction of forward conveyor movement. In either case, the grinding head is constructed and positioned so that it provides the additional function of a pinch roller, permitting small workpieces to be efficiently and uniformly ground. |
