Machine for machining long workpieces provided with cutting teeth, particularly for grinding endless saw blades

A machine (10) for machining long workpieces (32) provided with cutting teeth (60), particularly for grinding endless saw blades, having a machine base (40) and a machining device (12) which has a rotatably drivable tool (16), particularly a grinding wheel, for machining the workpiece (32), the machining device (12) being displaceable relative to the machine base (40) and the workpiece (32), wherein the machining device (12) has a rocker arm (24), on the one end region of which the rotatably drivable tool (16) is arranged wherein the rocker arm (24) is mounted by means of a pivot bearing arrangement (34) which permits a pivotal movement of the rocker arm (24) relative to the machine base (40), which results in the rotatably drivable tool (16) moving linearly relative to the machine base (40) and the workpiece (32), wherein the rotatably drivable tool (16) is linearly displaceable relative to the machine base (40) along a first linear displacement axis (G) by means of a linear drive (28, 30), and wherein the pivot bearing arrangement (34) has at least one pivot bearing plate (261, 262), which is pivotable about a first pivot axis (C) relative to the machine base (40) and on which the rocker arm (24) is mounted such that it is pivotable about a second pivot axis (E) parallel with the first pivot axis (C).
