Abstract
In a slicing by multi–wire saw, there are two kinds of system, a free abrasive grain system and a fixed abrasive grain system, which have good and bad points. Generally, free abrasive grain system is suitable for precision slicing in low cost, but slicing speed is slow, and also large quantity of industrial waste occurs. On the other hand, fixed abrasive grain system can be high speed slicing, but wire tool is very expensive. Therefore a free abrasive grain system is adopted when forming accuracy is necessary, and a fixed abrasive grain system is adopted when the processing efficiency is necessary. In this study, a half fixed abrasive grain system is proposed, which is located between a free abrasive grain system and a fixed abrasive grain system. Moreover, a trial manufacture result of a proposed half fixed abrasive grain wire tool is reported.
