Machining small and large bores
There is a wide range of full bore operations in the die & mould sector: From large bores for guide pillars and deep bores for the cooling system to high-precision bores for ejector pins. MAPAL offers a comprehensive portfolio of drilling and reaming tools for the individual production steps.
Tool overview for the following machining steps:
Piloting
Deep bores for cooling systems are very common mainly in the area of plastic injection. In order to get good guidance for extra long drilling tools, it is recommended to pilot the bores with correspondingly shorter tools. MAPAL not only supplies the right products here, but also the corresponding professional support to ensure the goals in terms of roundness and precision.
Since the drilling processes are often carried out on inclined surfaces, users avoid bending and breaking the tools by piloting the bores.

Drilling from solid
Due to the multitude of bore sizes and features, the die & mould sector offers a wide range of solid drilling tools. Tap drills, guide bores for ejector pins and partial pin holes are just a few application examples.
深孔钻孔
高达 40 和 50xD 的深孔在模具制造中非常常见。对此一应用情形需要特殊刀具。最常见的是单刃枪式钻，这些刀具用于特殊钻头。整体硬质合金钻头是孔径达 12 mm 的中、小型组件的实用替代品。深孔钻配备两个导向倒角，从而确保在孔中的良好导向。
铰孔
特定销钉和位置的孔在圆度和直径方面需要很高的精度。因此，强制要求最终的铰削过程。这些孔的预加工必须满足铰刀的要求，才能达到预期的效果。
MAPAL公司数十年所累积的专业知识为市场提供了广泛的产品种类，这些产品专门为满足特定要求而选择。
锪钻
对每个孔的边缘上通常用锥形锪钻进行精加工。锪孔是一种简单的应用，但有些孔具有特殊的表面质量要求。常用刀具由整体硬质合金制成，但也由高速钢制成。由于更好的性能和更高的表面质量，MAPAL公司的创新锥形锪钻为锪孔操作还提供了一定的优势。
