Abstract:
A wire saw, comprising:a continuous wire loop;cutting elements having steel cores with end-sides being axially spaced and provided on the continuous wire loop, wherein the continuous wire loop comprises a wire onto which the steel cores of the cutting elements are threaded;a guide sprocket wheel, wherein the continuous wire loop circulates over the guide sprocket wheel,elastomeric spacing elements, wherein the wire is encased between the cutting elements in the elastomeric spacing elements in a manner to nonrotatably affix the elastomeric spacing elements flexibly to and around the wire and to the adjacent end-walls of the steel cores;wherein the steel cores of the cutting elements define a waist portion having a central bore being cylindrically shaped, a diameter of the bore being essentially equal to a diameter of the wire, and the steel cores being centered on and abutting with the wire by way of the central bore,wherein the central bore merges with outwardly wide-angularly flared end-wall recesses defined at mutually opposite ends of the waist portion of the steel cores of the cutting elements, andwherein the elastomeric spacing elements have an arrow-shaped configuration wherein arrow points are pressed axially into the end-wall recesses, the arrow points from both sides resiliently centering the cutting elements relative to a longitudinal axis of the wire in a centered position defined by the waist portion of the steel cores.
