Abstract: A saw wire to cut hard and brittle materials is disclosed that comprises a steel wire that is provided with bends with segments in between. The average degree of bending of the bends is between 0.5% and 5%. Such a saw wire has a higher breaking load compared to saw wires having a conventional, higher average degree of bending. A method to measure the curvature is described as well as a process to make the inventive saw wire. The invention is applicable to any shaped saw wire for example a single crimped saw wire, a saw wire with at least two crimps in different planes, a saw wire with crimps rotating in a plane.
Abstract: A spool of saw wire is disclosed. The saw wire is wound on the core of the spool (718). The saw wire is made of steel wire (406) wherein two or more crimp deformations are implemented. Each of said two or more crimp deformations has a crimp direction that is perpendicular to the longitudinal axis. Each of the crimp directions is different from the other crimp directions. The saw wire on the spool comprises a number of elastic rotations per unit length applied in the elastic rotation direction. The spool with saw wire can give excellent processability in the sawing process.
