METHOD FOR MANUFACTURING INCLINED CURVE-TYPE BLADE BODY, BLADE BODY MADE THEREFROM, AND NAIL CLIPPER HAVING BLADE BODY THEREOF

摘要

The present invention is related to a method for manufacturing a blade body of a nail clipper having a 3-dimensional inclined curve-type blade, including steps of forming an inclined curve with a curvature Ra using a boundary line which is formed when the periphery of grinding media with a radius Rg in an upright position is merged with an upper inclined surface having a predetermined angleθ1 with respect to a vertical line, forming a lower inclined surface by extending the inclined curve downward at an angleθ2 corresponding to the angleθ1, forming blade bodies using the upper and lower inclined surfaces to be inner inclined surfaces of the blade bodies, and grinding the ends of the upper and lower inclined surfaces simultaneously via grinding media with the radius Rg, whereby forming upper and lower 3-dimensional inclined curve-type blades with the curvature Ra, respectively.
