Document Type and Number:
WIPO Patent Application WO/2015/079836
Kind Code:
A1
Abstract:
The objective of the present invention is to easily and reliably machine the end surface of a workpiece while holding the workpiece between a spindle and a countershaft. The machine tool (100), which cuts a workpiece (W) having a inclined surface (Wa) or a curved surface, is provided with: a spindle (7) that holds the workpiece (W) and rotates; moving devices (M1, M2, M3) that move a cutting tool (T1), which holds a linear cutting blade that cuts the workpiece (W), relative to the workpiece (W) in a direction combining a Z direction parallel to the axis line of the spindle (7), an X direction that is perpendicular to the Z direction and that regulates the amount of cutting of the workpiece (W, and a Y direction that is perpendicular to the Z direction and X direction; and an angle setting mechanism (19) that, in the state of the direction of the blade (Ta) of the cutting tool (T1) being inclined with respect to the Z direction when seen from the X direction, causes an inclination with respect to the Z direction when seen from the Y direction and causes a correspondence to the inclined surface (Wa) of the workpiece (W).
