Abstract

加工面における「むしれ」の発生を防止することが可能なボールエンドミルを提供することを課題とする。ボールエンドミル１０に球面状の先端部に形成された二つの切削刃１１・１２を設け、切削刃１１の刃面１１ａの内周端部を回転軸よりも回転方向の前方にオフセットした位置に配置し、切削刃１１の刃面１１ａの内周端部を半径方向について回転軸から切削刃形成側の反対側に所定距離だけ突出した位置に配置し、切削刃１１のうち切削刃１１の刃面１１ａと逃げ面１１ｂとの境界線である稜線１１ｃの中途部に形成された連結部１１ｆから切削刃１１の外周端部までの部分を主切削刃１１ｍとし、切削刃１１のうち連結部１１ｆから切削刃１１の内周端部までの部分を副切削刃１１ｓとし、切削刃１１の連結部１１ｆを切削刃１１において回転軸の軸線方向の先端側に最も突出した部分とし、切削刃１２についても切削刃１１と同様とする。
