| 提供一种抑制在丝锥加工中产生的剥落，并且也能使内螺纹精度稳定的螺纹切削用丝锥。通过在切削刃(28)的前倾面(30)上形成有突圆形状(32)，能够使剥落受到抑制。另外，当螺纹切削用丝锥(10)切入被削件时，作用在负侧的轴向载荷Fs降低，螺纹切削用丝锥不会行进过度，因此，螺旋丝锥(10)的切削状态良好，从而也使内螺纹精度稳定。 | ||||||

| むしれやタップ回転停止時の切れ刃の跡が雌ねじに発生することが抑制される管用テーパねじ加工スパイラルタップを提供する。 管用テーパねじ加工スパイラルタップ10は、3本以上5本以下であって、30°以上50°未満のねじれ角βを有するねじれ溝20を有し、回転軸線Cに直交する断面において回転軸線Cを中心とするねじれ溝20が占める角度をAG、回転軸線Cを中心とするランド22が占める角度をALとしたときの溝幅比AG/(AG+AL)は、0.3以上0.5以下である。これにより、30°以上50°未満のねじれ角βを有するねじれ溝20の存在によってむしれの発生が抑制されるとともに、切れ刃24と裏刃26との間が短くなってタップ回転停止時の切れ刃の跡が雌ねじに発生することが抑制される管用テーパねじ加工スパイラルタップ10が得られる。 |

| タップ加工中に発生するチッピングを抑制するとともに、めねじ精度も安定するねじ切削用タップを提供する。切れ刃28のすくい面30に突円形状32が形成されることで、チッピングが抑制される。さらに、スパイラルタップ10が被削材に食い付いたときの負側に作用するスラスト荷重Fsが低減され、スパイラルタップ10が進みすぎることもなくなり、従って、スパイラルタップ10の切削状態が良好となるのでめねじ精度も安定する。 | ||||||

Provided is a thread-cutting tap, which limits chipping that occurs during tapping and with which female thread precision is also stabilized. Chipping is limited by forming a protruding circular shape (32) on the cutting face (30) of a cutting edge (28). Moreover, the thrust load (Fs), which acts on the negative side when the spiral tap (10) bites into the material that is being cut, is reduced and excessive advancement of the spiral tap (10) is also eliminated. Consequently, because spiral tap (10) cutting conditions are favorable, female thread precision is also stabilized. |
