Abstract
【解決手段】 切れ刃16を形成するためのねじれ溝22が、シャンク12側から見た切削回転方向(右回転)とは逆の左まわりにねじれているため、凸条20の一対のフランクのうちシャンク12側に位置する後側フランクの切れ刃のすくい角が鋭角になり、切れ味が向上してめねじの口元の不完全山部分にカエリやバリが発生することが抑制される。特に、ねじれ溝22のねじれ角が5°以上であるため、後側フランクの切れ刃の切れ味が確実に向上するとともに、ねじれ角が30°以下であるため倒れに対して所定の剛性が得られ、カエリやバリが抑制されることと相まってめねじの精度が全体として向上する。

Description
(加工条件)
・被削材:SS400
・下穴径:φ10.8mm
・口元面取り:C1.5
・加工めねじサイズ:M12×1.25
・切削油:水溶性切削油剤
・機械:横型マシニングセンタ
図1は、本発明の一実施例であるねじ切りカッタ10を示す正面図で、このねじ切りカッタ10は、マシニングセンタ等の主軸に把持されるシャンク12と、一対の切れ刃16が設けられた刃部18とを、軸方向に一体に備えている。刃部18の外周部には、形成すべきめねじ30(図2参照)のねじ溝に対応する断面形状のリードの無い凸条20が軸方向にめねじ30と同じピッチで多数設けられており、その凸条20を分断するように一対のねじれ溝22が形成されることにより、そのねじれ溝22に沿って切れ刃16が設けられている。本発明のねじ切りカッタ10は、シャンク12側から見て右まわりに回転駆動されることにより切削加工を行うもので、ねじれ溝22は、その切削回転方向と逆の左まわりにねじれているとともに、そのねじれ角は5°〜30°の範囲内で設けられている。また、一対の切れ刃16は、めねじ30のねじ山の山頂(めねじの内径)を含めて切削する総形切れ刃で、凸条20の間の溝部分も切れ刃として機能する。このねじ切りカッタ10は、超硬合金にて一体に構成されているとともに、刃部18の表面にはTiAlNの硬質被膜がコーティングされている。
(加工条件)
・被削材:ADC12
・切削速度:150m/min
・下穴径:28.5mm
・加工めねじサイズ:M30×1.5
・ねじ立て長さ:21mm
・切削油:水溶性切削油剤
・機械:たて型マシニングセンタ
