Title:
A machine tool and a cutting method
Document Type and Number:
Japanese Patent JP6206504
Kind Code:
B2
Abstract:
[Problem] To easily and reliably machine an end surface of a workpiece while holding the workpiece between a main spindle and a counter spindle. [Solving Means] A machine tool 100 for cutting a workpiece W having an inclined surface Wa (or a curved surface) includes a main spindle 7 that holds and rotates the workpiece W, a moving device (M1, M2, M3) that moves a cutting tool T1 relative to the workpiece W in a direction obtained by combining a Z direction parallel with the axis of the main spindle 7, an X direction that is perpendicular to the Z direction and determines the amount of cutting of the workpiece W, and a Y direction perpendicular to the Z direction and the X direction, and an angle setting mechanism 19 that causes the direction of an edge Ta of the cutting tool T1 to match the inclined surface Wa of the workpiece W by inclining the direction of the edge Ta with respect to the Z direction when seen from the Y direction in a state in which the direction of the edge Ta is inclined with respect to the Z direction when seen from the X direction.
