ABSTRACT:
A method of grinding a metal billet by supporting a group of grinding wheels in a circular array above the slab, bloom or billet, rotating the grinding wheels individually, and orbiting the grinding wheels about a central axis extending transversely of the workpiece. The workpiece is moved back and forth under the grinding wheels and the grinding wheels are preferably tilted one way and then the other as the workpiece moves back and forth so that the wheels will grind at a negative rake. The grinding wheels are supported in a manner such that they can float and thus follow the contour of the material being ground.
