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

  5. Countersinking

Pilotieren

Tiefe Bohrungen für Kühlsysteme sind hauptsächlich im Bereich der Kunststoffinjektion sehr verbreitet. Um eine gute Führung für extra lange Bohrwerkzeuge zu erhalten, empfiehlt sich eine Pilotierung der Bohrungen mit entsprechend kürzeren Werkzeugen. MAPAL liefert hier nicht nur die richtigen Produkte, sondern auch den entsprechend professionellen Support, um die Ziele in Sachen Rundheit und Präzision sicherzustellen.
Da die Bohrprozesse häufig auch an schrägen Oberflächen durchgeführt werden, vermeiden Anwender mit der Pilotierung der Bohrung ein Biegen und Brechen der Werkzeuge.

Taladrado de agujeros profundos

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.
  • MEGA-Deep-Drill

    Solid carbide deep drill
    • Process-reliable and efficient production of deep bores up to 40xD
    • Up to 80 percent shorter machining times compared to single-lip drills
    • Self-centring chisel edge
    • Four guiding chamfers for high bore quality


Reaming

The bores for certain pins and positions require a high degree of accuracy in terms of roundness and diameter. A final reaming process is therefore mandatory. The pre-machining of these bores must also meet the requirements of the reaming tools in order to achieve the desired results.

Decades of expertise at MAPAL means a wide range of available products that are individually selected for specific requirements.

Avellanado

El perfil de cada perforación se suele mecanizar previamente con un avellanador cónico. El avellanado es una aplicación sencilla, aunque algunas perforaciones exigen requisitos especiales de calidad superficial. Las herramientas más utilizadas son de material completo en metal duro, pero también las hay de acero rápido. Los innovadores avellanadores cónicos de MAPAL ofrecen otras ventajas para el avellanado como un rendimiento mejor y más calidad superficial.
