Device for grinding saw teeth and a corresponding method

A device for grinding pre-milled and hard metal-tipped teeth of saw bands, the device for grinding comprising a feed device for feeding a temporarily formed workpiece in a timed manner, wherein a temporary workpiece is temporarily formed from a plurality of saw bands which are parallel to one another, the device for grinding further comprising a clamping device which clamps the plurality of saw bands against one another, the device for grinding further comprising a grinding unit for simultaneously grinding a plurality of teeth, wherein the grinding unit comprises a grinding wheel with a plurality of grinding profiles, wherein the grinding unit has a clearance arranged in the area of a tooth tip of the teeth of the saw bands in the direction of the tooth face of the teeth of the saw bands so that the grinding unit grinds both the tooth backs and the tooth faces of the teeth of the saw bands to a desired final dimension in exactly one linear movement of the grinding unit orthogonally to a longitudinal axis of the plurality saw bands such that the tooth tip in the area of the tooth back is not damaged while the tooth tip in the area of the tooth face is completely ground down to the final dimension, such that the saw bands of the temporarily formed workpiece are each ready for use and do not require further regrinding.
