Abstract:
A cutting machine for cutting rails of railway tracks, the cutting machine comprising:a vise for clamping to a rail of a railway track to cut the rail;a planar grinding wheel defining a plane;a support guiding the planar grinding wheel, pivoting transversely with respect to the metal part being cut, and being pivotally connected to the vise;an engine having an engine block, rotationally driving the planar grinding wheel, and mounted on the support; andan arm having a first end at which the planar grinding wheel is mounted to the engine block, and a second end at which the arm is pivotally mounted to the engine block about a first pivot pin, parallel to a second pivot pin pivotally connected to the vise and, when clamped to the rail to be cut, parallel to a longitudinal substantially horizontal axis of the rail to be cut, the engine block being permanently connected to the vise so that the engine may not be reversed or turned over about a substantially vertical axis when the vise is clamped to the rail to be cut, may not be turned up or upside down about a substantially horizontal axis when the vise is clamped to the rail to be cut, and is always located on a first side of the plane of the planar grinding wheel with respect to the vise.
