In the present paper, piano wire on which spiral grooves are ground continuously is developed and it is used for a multiwire saw as a tool. The spiral-grooves ground round about the wire possess a sort of "abrasive grain carrier effect". Accordingly, the abrasive grains can easily enter into the part being processed.This report deals with the mechanism of a trial apparatus to make the spiral-grooved wire tool and with the slicing characteristics of the spiral-grooved wire tool. The results obtained through the theoretical analysis and a series of experiments are as follows : (1)Theoretical results considered on the basis such assumptions that a holding effect of abrasive grain in slurry is related to volume in the hollow of spiral grooves are approximately confirmed by experiments(when the grain size is same or less with grooves depth). (2)Machining efficiency used the spiral-grooved wire tool shows two times as much as the normal wire tool. (3)Wear of multigrooved pulley used the spiral grooved wire is slightly larger than the case of ordinary wire. (4)Thickness of the sliced wafer used the spiral grooved wire is as thick as the case of ordinary one.
