ABSTRACT:
A grinding machine equipped with a grinding band consists substantially of a motor-driven contact disk supported in a machine frame, which has a horizontal axle, a rotatable rerouting unit, which has a shaft parallel with the axle, and wherein the grinding band is slack and not bend-resisting, and is guided over the contact disk and the rerouting unit. In a take-up region of the contact disk there are disposed lateral guidance jaws of an abrasion-resistive ceramic material. A lower strand of the grinding band is suspended downwardly, while being acted upon by band-tensioning means. The rerouting unit includes a plurality of U-shaped wire members connected to a hub of the rerouting unit, spaced radially therefrom, and spaced from one another, whose outwardly concave cross-rods form a line-like support for the grinding band. As the U-shaped wire members are very lightweight, the rerouting unit has a very low moment of inertia, so that it can follow any changes in the rotating velocity of the grinding band almost instantaneously, and in a slip-free manner, even at the lowest band tension.
