Title:
穴加工方法および中ぐり工具
Document Type and Number:
Japanese Patent JP7373161
Kind Code:
B2
Abstract:
To provide a method for realizing the efficient hole processing.SOLUTION: A hole processing method comprises the steps of: relatively rotating a processing object material 3 with respect to a boring tool; and relatively feeding the boring tool with respect to the processing object material 3 in a direction at a prescribed angle with respect to a rotation axial line of the processing object material 3 in such a state that a first cutting edge 11 and a nose cutting edge 13 are cut into the inner surface of the hole of the processing object material 3. In the feeding step, an angle formed between a line segment connecting the boundary point between the first cutting edge 11 and the nose cutting edge 13 to the nose center of the nose cutting edge 13 and a line segment connecting a point at which the nose cutting edge 13 cuts into the inner surface of the hole with the largest amount to the nose center is set to be 30 degrees or less. An angle formed by the first cutting edge 11 cutting into the processing object material 3 with respect to a surface vertical to the longitudinal direction of a shank is set to be within a prescribed range.SELECTED DRAWING: Figure 4
