摘要： A wire saw includes a saw wire forming a sawing section for engagement with a workpiece to be cut. A guide is arranged to position the sawing section of the saw wire relative to the workpiece. The guide is configured to permit a plurality of independent directions of movement such that, in addition to an advance of the sawing section in the direction of the workpiece to be cut, the sawing section can be lengthened and/or shortened. A wire-storage-and-tensioning device is arranged for loading, unloading, and tensioning the saw wire when a position and/or a length of the sawing section is changed by the guide. The guide has, for each of the plurality of independent directions of movement, a separate wire storage associated with the given individual direction of movement.
