MAPAL erweitert Produktportfolio in der Bearbeitung der Schieberbohrung

Die Schieberbohrung ist ein zentrales Element in Hydraulikkomponenten wie Ventilgehäusen oder Axialkolbenpumpen. Deren Fertigbearbeitung mit Feinbohrwerkzeugen gehört seit jeher zur Kernkompetenz von MAPAL. Die Expertise des Unternehmens steht nun auch für die Vorbearbeitung zur Verfügung, sodass Kunden die komplette Bohrungsbearbeitung aus einer Hand erhalten.

MAPAL hebt sich von Marktbegleitern ab, indem der Werkzeugspezialist fertige und auf die Kundenbedürfnisse zugeschnittene Lösungspakete für Hydraulikkomponenten zur Verfügung stellt. Diese wurden durch intensives Komponentenmanagement ausgearbeitet und resultieren kontinuierlich in Innovationen. Aktuelles Beispiel sind zwei Werkzeuge, die durch ihre hohe Prozesssicherheit und eine Reihe technischer Features hervorstechen.
 

The pilot drill enables efficient piloting, reducing work processes and saving tool changes. Flexibility in responding to customer requirements is guaranteed with two pilot drill designs with three and five cutting edges respectively. This is required due to the various casting properties of raw parts. 

With the new pilot drills, MAPAL is capable of offering a standardised solution for every raw casting scenario. The drill with three cutting edges is primarily used in good casting conditions, while the option with five cutting edges is used in unstable or poor casting conditions. It enables higher feeds and offers ultra-precise results with its high degree of positional accuracy. Both versions ensure maximum cost-effectiveness.
 

The multi-chamfer technology also makes the tools well-suited for regrinding, helping to reduce the cost per bore. The boring tool prevents the formation of cast rings, which can lead to scrap for the customer. The tool’s robust design makes drilling depths of up to 10xD possible and is therefore ideal for critical length and diameter ratios such as in large valve housings.

MAPAL pursues a holistic approach when machining the spool bore. The tools are dealt with in the context of the entire machining process, not in an isolated way. The new tools are designed to be optimally aligned for the subsequent machining step. 

By expanding its range with high-performance pre-machining tools, MAPAL positions itself as a holistic technology partner in fluid power technology and provides customised processes to enable customers to achieve not only high productivity and quality but to source all machining steps from a single source.
