ABSTRACT:
An apparatus grinding a steel billet to remove surface cracks. The billet is advanced in the direction of it longitudinal axis while being rotated. The apparatus includes a grinding wheel mounted in a bearing in a movably mounted support member. In order to accurately and simply control the penetration depth of the grinding wheel, a stop member is mounted on the support member. In one embodiment, the stop member is a segment of a circle mounted eccentrically relative to the grinding wheel. In another embodiment, the stop member is a segment of a spiral mounted coaxially with the grinding wheel. The stop member engages the surface of the billet. Two arrangements are described for rotating the billet at an increased speed while grinding the edge regions.
