A new cutting device driven by an enlargement mechanism with a PZT drive has been developed to realize position the cutting tool from nm to mm order. In this study, basic mechanical principal of a new developed enlargement mechanism consists of fluid chamber, a PZT device, and cutting tool stage is reported. This developed device can enlarge 4 times of stroke than the original one of the PZT. The dynamic characteristics show DC to 100 Hz which is enough high to realize the non-circle cutting. The non-circle components are machined by the developed device. The profile accuracy obtained settles in ±3μm by the repetitive control method.
