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.

Taladrado de agujeros profundos

La perforación profunda de hasta 40 y 50xD es muy habitual en la fabricación de moldes y troqueles. Para este uso se requieren herramientas especiales. Las más corrientes son brocas de un filo que se emplean en taladradoras especiales. La broca fabricada por completo en metal duro es una buena alternativa para componentes pequeños y de tamaño intermedio con un diámetro de taladrado de hasta 12 mm. La broca cañón dispone de dos biseles guía, lo que garantiza que se introduzca correctamente en el agujero.
