Embodiment Construction

[0019] The present invention is a helical milling hole method and device based on a numerically controlled machine tool. The device is mainly installed on a numerically controlled machine tool by using a processed knife handle, and the rotation of the main shaft of the numerically controlled machine tool is used for the revolution in the helically milled hole, and The feed is provided by the CNC machine tool, and the device itself provides the rotation of the tool and the adjustment of the offset. In this way, when the machine tool spindle rotates at a slow speed, the machining tool will revolve around the axis of the machine tool spindle, and cooperate with the feed of the machine tool spindle to finally realize a The tool can perform helical milling operations on various hole diameters. The specific implementations of the method and device of the present invention will be described in detail below.
