摘要： A method of slicing an ingot wherein a pre-cut work 3 in which a holding member 2 extending over the entire length of a side surface of a cylindrical ingot 1 is bonded to the side surface of the ingot 1 is set on a slicing apparatus 4, and the pre-cut work 3 is split into a multiplicity of pieces over its longitudinal direction so as to obtain disk-shaped works 5 to be ground, characterized in that a retaining member 2 is used in which a retaining layer 7 which is directly bonded to the side surface of the ingot 1 by a first adhesive agent having an adhesive strength sufficient to receive a rotating force due to a grinding apparatus 6 in a subsequent grinding process, an intermediate layer 8 which is bonded to said retaining layer 7 in a superposed manner by a second adhesive agent whose adhesive strength deteriorates more than that of the first adhesive agent under a fixed condition, and a supporting layer 11 which is connected to said intermediate layer 8 and is connected to a supporting portion 10 of said slicing apparatus 4 are integrally superposed one on top another.

摘要翻译： 一种切割锭的方法，其中将切割工件3设置在切片装置4上，其中在圆锭1的侧表面的整个长度上延伸的保持构件2结合到锭1的侧表面 并且预切割工件3在其纵向方向上被分成多个部件，以便获得待研磨的圆盘状工件5，其特征在于，使用保持部件2，其中保持层7直接 通过具有足以在随后的研磨过程中由于研磨装置6接受旋转力的粘合强度的第一粘合剂粘合到锭块1的侧表面上的中间层8，其结合到所述保持层7中 在固定状态下，粘接强度劣于第一粘接剂的粘接强度比第二粘接剂重叠的方式，连接在所述中间层8上的支撑层11与支撑体 所述切片装置4的固定部分10一体地叠置在另一个上。
