A vibration cutting machine having piezoelectric actuator located parallelly

摘要

According to the present invention, two piezoelectric actuators are disposed in an up and down parallel direction on an elastic hinge axis capable of rotating and translational movements so that the upper and lower parallel arrangements can oscillate while drawing an elliptic trajectory only in a plane consisting of the cutting direction and the cutting direction. An oscillating cutting tool post having a piezoelectric actuator, wherein the oscillating cutting tool for vibrating a tool installed in a tool mounting unit using a piezoelectric actuator to cut a workpiece, wherein the tool mounting portion has an elastic hinge shaft for elastically rotating the tool. The piezoelectric actuator is installed up and down in parallel in a position symmetrical on the same plane with respect to the elastic hinge axis to provide a feed force to the tool mounting portion, so that the tool is driven by the piezoelectric actuator. Even if the cutting direction forms an elliptical trajectory in the same plane The.;Cutting, vibration, piezo actuator, elasticity, rotation, parallel structure
