Title:
MACHINING METHOD FOR FEMALE SCREW AND DEVICE FOR SAME
Document Type and Number:
WIPO Patent Application WO/2014/020900
Kind Code:
A1
Abstract:
In the present invention, when a female screw is machined into a hole in a metal material with a hole for female screw machining, with the metal material in a held or secured state and the male-screw-shaped tool solely revolving in a fixed horizontal plane and not rotating, gradual pressure is applied to a machining section of the male-screw-shaped tool and the shape of the machining section is transferred to the inner circumference of the hole, thereby forming a screw groove therein. The present invention comprises a processing machine body for holding or securing the metal material with the hole for female screw machining, an X axis-Y axis table that is capable of controlled movement in an elliptical oscillation when exerting the necessary pressure on the processing machine body, and the male-screw-shaped tool fixed to the X axis-Y axis table. While gradual pressure is applied to the machining section of the male-screw-shaped tool, the shape of the machining section is transferred to the inner circumference of the hole and thereby forming the screw groove therein solely by the revolving motion of the male-screw-shaped tool fixed to the X axis-Y axis table in a fixed horizontal plane, without itself rotating.
