A grinding machine for conditioning the surfaces of steel slabs, billets, or the like to remove scale, exposed or hidden cracks and other surface irregularities. The entire grinding machine including the grinding wheel head and its supporting carriage travels on rails so that the grinding wheel may traverse the work. A rotary turret pivottally supports the boom housing for fore and aft rocking movements, and the grinding head is carried at the outer end of a relatively short boom which is fixed to and projects outwardly from the housing so that controlled angular movements of the turret will swing the grinding head and its associated grinding wheel over the surface of the work in order that the rotating grinding wheel may be shifted to an angular position wherein the grinding direction at the periphery of the wheel matches or nearly matches the longitudinal direction of any surface cracks which are undergoing spot eradication. The operator's control cab is positioned on the movable grinding machine carriage at a location where the grinding head is clearly and closely visible at all times.
