Document Type and Number:
WIPO Patent Application WO/2014/171244
Kind Code:
A1
Abstract:
Provided is a machine tool capable of high-precision, high-efficiency machining of a surface to be cut having a cylindrical shape and a protruding section provided on both sides thereof in the axial direction. The machine tool comprises: a main shaft (2) supporting an end section of a workpiece (W) and rotating; a tool (20A) movable relative to the main shaft (2) in the X-axis and Y-axis directions; and a machining control device (30) that controls the movement of the tool (20A). The tool (20A) has a linear blade tip. The blade tip is parallel to the Y-Z plane and is inclined relative to the Z-axis direction. The machining control device (30) causes the tool (20A) to move to a stipulated Y-axis cutting feed start position, then causes the tool (20A) to move in the Y-axis direction such that the blade tip of the tool (20A) passes through the surface to be cut (F1) on the workpiece (W).
