MACHINE TOOL

摘要

The purpose of the invention is to provide a machine tool with which high quality machining of a workpiece obtained from mainly difficult-to-machine material can be stabilized and which limits the occurrence of fire while also being practical, not limiting workpiece machining shape, and being capable of performing low frequency vibration cutting that can finely fragment swarf even when vibrating the cutting tool and/or workpiece at low frequency on multiple axes. To achieve the purpose, the machine tool is provided with a cutting tool holder (5) that holds the cutting tool (4) for machining the workpiece and a rotation mechanism (3) that holds the workpiece (2). The cutting tool holder (5) or the rotation mechanism (3) is provided to be freely movable so that the cutting tool (4) is moved relative to the workpiece (2) in multiple axial directions. A control device (8) is provided for controlling the movement of the cutting tool holder (5) or the rotation mechanism (3) so that the workpiece (2) and the cutting tool (4) are synchronously vibrated relative to each other at low frequency in multiple axial directions.
