Abstract
A new cutting tool holder that enables to extend the stroke of a PZT more than 100mm has been developed. The cutting tool holder consists of two different area's fluid chamber and a PZT. The extension magnitude is almost 100 times than the one of original stroke. On the other hand, this developed holder can reduces the stroke by the change of layout of fluid chamber. In this case, the reduction of stroke is about 1/100 times than that of the original stroke. In this report, the basic performances are evaluated and the some applications are introduced by this developed tool holder.
