Cutting machining apparatus

Abstract

An object of the present invention is to provide a cutting machining apparatus capable of suppressing an increase in size. The cutting machining apparatus includes: a cutting device that cuts a workpiece by rotation of a tool; a holding device that holds the workpiece; a moving device that relatively moves the tool and the workpiece in an extending direction of a rotation axis of the tool; and a control device that controls the cutting device, the holding device, and the moving device to cut the workpiece along a spiral machining path. The cutting device includes: a spindle that rotationally drives the tool; and a tool swinging device that swings at least the tool around a first axis parallel to the rotation axis. The holding device includes a workpiece rotating device that is provided independently of the tool swinging device and rotates the workpiece around a second axis parallel to the first axis.
