| 大多数孔是钻削而成的，但是，现代机床提供了一种替选方法：铣削孔，该方法有许多优点，特别是在孔尺 |
| 寸非常大、机床功率和扭矩受限时，该方法更显优势。通常，精密孔（IT7 或更高）需要一个二次精加工工序， |
| 该精加工工序常由镗刀或铰刀完成，但是，如果采用铣削孔的方法，则可省去该精加工工序。使用精密的整体硬 |
| 质合金立铣刀，就可完全替代上述需要二次精加工工序的孔加工方法。采用正确的刀柄类型，整体硬质合金立铣 |
| 刀便能够提供高精度和高光洁度孔。孔径和批量生产将决定加工方法的选择方向。 |

| Most holes are drilled but modern machine tools provide alternative methods in the form of |
| milling, which can be advantageous, especially when the size of the hole is large and power and |
| torque is limited. Precision holes (IT7 or better) normally require a secondary finishing |
| operation, made by a boring tool or reamer, but also here milling may be an alternative. Using a |
| precision solid-carbide endmill may also be an alternative as these, in the right type of tool |
| holder, provide high precision and finish. Hole diameter and batch size will determine the |
| direction for methods to be considered. |
