Problems solved by technology

Further, the tendency to use wire movement profiles with high accelerations and decelerations (e.g., reciprocating movement of the cutting wire) adds to the challenges with regard to wire tension control during cutting because such accelerations and decelerations create disturbances in the wire tension

Abstract

A pulley configured for a wire saw device having a wire forming a wire web is described. The pulley includes a wheel portion (410) around the pulley axis (410a), and a wire guiding portion (455) radially outward of the wheel portion for guiding a wire. The radial stiffness of the wheel portion is lower than the stiffness of the wheel portion in direction of the pulley axis.

Description

technical field [0001] Embodiments of the invention relate to a pulley for and in a wire saw device and a wire saw device. More specifically, embodiments of the present invention relate to pulleys configured for wire saw devices, and wire saw devices for cutting or sawing hard materials such as blocks of silicon, sapphire or quartz, for example, for cutting silicon wafers , for rectangle formers, for truncators, and so on. Background technique [0002] Wire saw devices exist for cutting blocks or bricks, thin slices, eg semiconductor wafers, from a piece of hard material such as silicon. In such devices, a stretched wire is supplied from a spool and is guided and tensioned by pulleys for guiding the wire in the cutting zone. [0003] Today, there is a tendency to use thinner wires, thereby reducing cutting thickness and reducing wasted material. There is also a desire to use diamond wire. These thinner wires and diamond wires are generally more susceptible to damage, and...
