莫氏锥度是一个 锥度的国际标准,用于静配合以精确定位。莫氏锥度有0,1,2,3,4,5,6共七个号,每一型号的公称直径大小分别为9.045,12.065,17.78,23.825,31.267,44.399,63.348。主要用于各种刀具(如钻头、铣刀)、刀套、刀杆及机床主轴孔锥度。

莫氏锥度号与锥度C及圆锥角α的关系为:

0号:锥度C = 2 × tan(α/2) = 2 × tan(29°27') ≈ 0.05205

1号:锥度C = 2 × tan(α/2) = 2 × tan(25°43') ≈ 0.04988

2号:锥度C = 2 × tan(α/2) = 2 × tan(25°50') ≈ 0.04995

3号:锥度C = 2 × tan(α/2) = 2 × tan(26°16') ≈ 0.05303

4号:锥度C = 2 × tan(α/2) = 2 × tan(29°15') ≈ 0.07556

5号:锥度C = 2 × tan(α/2) = 2 × tan(20°26') ≈ 0.10556

6号:锥度C = 2 × tan(α/2) = 2 × tan(29°36') ≈ 0.14940

莫氏锥度标准尺寸表如下:

| 莫氏锥度号 | 锥度(2tanα) | 大端直径D(mm) | 圆锥角2α(°) | 斜角α(°) | 斜度(tanα) |

|------------|--------------|----------------|---------------|-----------|-------------|

| 0号| 1:19.212 | 9.045 | 2°58'54" | 3.2° | 0.05205 |

| 1号| 1:20.047 | 12.065 | 2°58'31" | 3.5° | 0.04988 |

| 2号| 1:20.020 | 17.78 | 2°57'49" | 4.0° | 0.04995 |

| 3号| 1:20.990 | 23.825 | 2°56'35" | 4.5° | 0.05303 |

| 4号| 1:24.000 | 31.267 | 2°53'25" | 5.3° | 0.07556 |

| 5号| 1:30.000 | 44.399 | 2°49'45" | 6.3° | 0.10556 |

| 6号| 1:37.500 | 63.348 | 2°45'15" | 7.9° | 0.14940 |

莫氏锥度通过其标准化的锥度和角度,实现了在机械加工和制造中的精确定位和便捷拆卸。
