ABSTRACT:
A wire saw has rotatably mounted two or more wire-guide rollers, around wh a sawing wire is wound, two adjacent wire-guide rollers forming the boundary of a wire web, which has a certain width. The wire saw has at least one drive, by means of which the wire-guide rollers are caused to rotate. The wire-guide roller, which forms a boundary of the wire web, is supported on an elongated support which is connected at one end to a machine frame and has an opposite, freely suspended end. There is also a method which can be carried out with the wire saw. The wire saw has the support passed through the wire-guide roller in its longitudinal direction and forms a fixed unit with the machine frame. A wire-guide roller forming a boundary for the wire web is designed as a sleeve which sits on a support roller. Allocated to the wire-guide roller is at least one thrust bearing so that an axial center of the wire-guide roller is not displaced or is only slightly displaced during an axial thermal expansion of the wire-guide roller as a result of overheating.
