Bonded-abrasive wire saw
First Claim
1. A wire saw comprising in combination:
- a. an elongated abrasive carrier comprising a plurality of discrete high tensile strength metal strands having a fatigue limit in excess of about 60,000 p.s.i. longitudinally interlocked in contacting relationship, said strands having complementally nesting cross-sectional configurations forming in juxtaposed combination a generally circular transverse cross section having a cross-sectional void space of less than about 20 percent, the largest cross-sectional dimension of each of said strands being no more than about one half the largest cross-sectional dimension of said abrasive carrier; and
b. circumferentially-discontinuous discrete segments of bonded abrasive particles fixedly secured adjacent the outer periphery of the elongated abrasive carrier and longitudinally disposed spacedly therealong whereby to abrade a workpiece when said wire saw is brought into abrading contact therewith.

Abstract
This improved wire saw for sawing various materials, including, for example, granite, marble, limestone and the like comprises in combination an elongated abrasive carrier of novel design and bonded abrasives secured thereto. The carrier comprises a plurality of discrete high tensile strength strands, e.g., high-alloy steel strands, longitudinally interlocked in contacting relationship. The strands have complementally nesting cross-sectional configurations which form, in juxtaposed combination, a generally circular transverse cross section having a cross-sectional void space of less than about 20 percent, preferably less than 15 percent. Bonded abrasive particles, preferably super-abrasive particles such as natural or synthetic diamonds or cubic boron nitride particles or mixtures thereof, are fixedly secured to the outer periphery of the elongated multi-membered abrasive carrier, preferably in the form of discrete segments longitudinally disposed therealong.

21. A wire saw comprising in combination:
-
a. an elongated abrasive carrier in the form of a closed loop, said carrier comprising a plurality of discrete strands of high tensile strength steel having a fatigue limit of at least about 100,000 p.s.i., the strands being longitudinally interlocked into contacting relationship and having complementally nesting cross-sectional configurations forming in juxtaposed combination a generally circular transverse cross section having a cross-sectional void space of less than about 15 percent, the largest cross-sectional dimension of each of said strands being no more than about one half the largest cross-sectional dimension of said abrasive carrier; and b. circumferentially-discontinuous discrete segments of super-abrasive particles having a Knoop hardness in excess of about 3000 kg/mm2 bonded in a powdered metal matrix and fixedly secured at spaced intervals adjacent the outer surface of the elongated abrasive carrier and longitudinally disposed therealong whereby to abrade a workpiece when said wire saw is brought into abrading contact therewith. - View Dependent Claims (22, 23, 24)
