MATERIAL FOR HOLDING WORKPIECE TO BE GROUND

摘要

PROBLEM TO BE SOLVED: To provide a material for holding a workpiece to be ground, which can suppress the occurrence of scratches on a surface to be ground and peripheral end surfaces in grinding the workpiece to be ground.

SOLUTION: The material for holding the workpiece to be ground has a through hole arranged so as to hold the workpiece by inserting the workpiece into the through hole. The material is substantially composed of fiber integrated materials which contain meta-linked aramid fibers as a main composition, and is a flat material compressed in a heated state. The fibers are fixed with each other by thermal fusion. The material contains the meta-linked aramid fibers as the main composition, and may contain the para-linked aramid fibers. The fibers substantially containing the meta-linked aramid fibers as the main composition are exposed outside the wall surface of the through hole. The occurrence of scratches are suppressed by the exposed fibers serving as cushioning materials.
