硬质合金钻削的演变
多年来,硬质合金钻头的普及程度显著提高。在20世纪80年代,由于机床和夹具的稳定性有限,它的应用条件仍然很严格。然而,这不再是现代数控机床的障碍。这就是为什么整体硬质合金钻头现在广泛应用于各种机器的原因。
近年来,铣床和车削机床的稳定性和生产能力都有了很大的提高。此外,在基础材料、涂层和几何领域,工具的发展已经起飞。因此,现在可以用硬质合金钻钻非常深的孔。这在以前是不可想象的,因为这会立即导致钻头断裂。
然而,整体硬质合金钻头仍然主要用于最大深度的孔。3 xd或5 xd。随着越来越多的机床配备高压冷却通过主轴,使用整体硬质合金钻头的冷却通道已经起飞。
硬质合金钻削的优点和缺点

- 更高的孔精度和尺寸稳定性
- 更好的定位精度
- 孔表面质量更好
- 能用于较硬的材料吗
- 更耐高温发展
- 在系列化生产中,钻孔成本较低
缺点
- 比高速钢或高速钢钻头更贵
- 对机器、夹具或工件的不稳定更加敏感
- 高转速要求
Dormer生产的硬质合金钻头
Dormer Pramet主要致力于开发适用于广泛应用的工具。毕竟,许多生产公司使用各种不同的材料。那么,更有效的是利用工具来实现所有这些材料的良好生产力。Dormer Pramet的整体硬质合金钻头包括两个系列:Force X钻头和Force M钻头。
Force X Series:
Force M series
This technology developed by Dormer is now being applied to the solid carbide drills, so that the Force X and Force M drills contribute to the sustainable use of the raw materials needed for the production of carbide. Resharpening becomes much easier and therefore cheaper.
Our solid carbide drills only perform optimally if they are clamped in a high-accuracy recording. Therefore, the shaft is manufactured in accordance with DIN 6535 HA, i.e. a cylindrical unit shaft in H6 tolerance. It is especially suitable for the crimp holder or hydraulic tensioner. Of course, it can also be incorporated into a collet chuck, but in that case we recommend a precision collet chuck (with increased concentricity).
If only weldon holders are available, grinding a chuck on the drill is an option. However, this can negatively affect the accuracy and tool life of the drill at high speeds.
