Abstract:
1. 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).
