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.
On a rendered example component, an operation is highlighted.
Tool overview for the following machining steps:
  1. Piloting
  2. Drilling from solid
  3. Deep hole drilling
  4. Reaming
  5. Countersinking

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.

Deep hole drilling

Deep drilling up to 40 and 50xD is very common in the die & mould sector. This type of drilling requires specialised tools. The most common are single-lip drills, with these tools being used on special drilling machines. Solid carbide drills are a real alternative for small and medium-sized components with bore diameters of up to 12 mm. The deep hole drills are equipped with two guiding chamfers and thus ensure good guidance in the bore.

リーミング

特定のピンや位置へのボーリングは、真円度や直径など高い精度が要求されます。そのため、最終的なリーミング作業が必須となります。これらの穴の前処理は、望ましい結果を得るためにリーミングツールの要求を満たす必要があります。
