    • Wire spools used for multiple wire saws for slicing one or more wafers from a workpiece composed of semiconductor material using a wire web including parallel wire sections coated with bonded abrasive grain. The wire spools include a first wire spool configured as a dispensing spool and a second wire spool configured as a receiver spool. A sawing wire coated with bonded abrasive grain runs from the first wire spool via at least one deflection roll to the wire web and from the wire web via at least one deflection roll to the second wire spool. The sawing wire enters into guide grooves of the deflection rolls at an alignment angle α1 and exits the guide grooves of the deflection rolls at an alignment angle α2. The sawing wire has a single layer winding on each of the first and second wire spools.
    • 用于多个线锯的线芯,用于使用包括涂覆有粘合磨料颗粒的平行线段的线网将来自由半导体材料组成的工件切片一个或多个晶片。 线轴包括构造为分配线轴的第一线轴和构造为接收器线轴的第二线轴。 涂覆有粘结磨料颗粒的锯线从第一线卷轴经由至少一个偏转辊延伸到丝网,并且通过至少一个偏转辊到丝网卷到第二线卷轴。 锯线以对准角α1进入偏转辊的引导槽,并以对准角α2离开偏转辊的引导槽。 锯线在第一和第二线轴的每一个上具有单层缠绕。
