Abstract

A method and a device for cutting a workpiece (1, 21) in a wire saw is described, wherein a workpiece (1, 21) is fixed in a wire saw by means of a mounting beam (2, 22). In the method according to the invention, the generation of a mark or a step on the cutting area along the cutting slit at the transition from the workpiece to the mounting beam (2, 22) is moved further to the edge of the cutting area or is avoided entirely. Therefore, the workpiece (1, 21) is held during the cutting operation in the wire saw by a mounting beam (2, 22) such that while one of the two piercing points (9; 29) lies on the surface of the workpiece (1, 21) and while simultaneously the other (10; 30) of the two piercing points (9, 10; 29, 30) lies on the surface of the mounting beam (2; 22), the piercing point lying on the surface of the workpiece is the entry side piercing point.
