New BFS connection for replaceable head milling systems

Easy handling, rigid connection, optimal cooling

MAPAL has introduced a new, patent-pending bayonet-type connection for milling cutter systems with a replaceable head at the AMB 2024. Users benefit from very easy handling with rigid connection and optimal cooling. The tool manufacturer also saves carbide with the connection, conserving resources.

  • A ring of cooling channel bores at the tool holder ensures that the coolant is directed straight to the cutting edges.

The functional principle of the new connection couldn’t be easier: the replaceable head only has to be inserted and turned 90 degrees to be locked. That’s a lot easier than the previous system for replaceable head milling cutters from MAPAL or comparable systems where the replaceable head is threaded and has to be screwed in several turns. 

The bayonet system achieves very high rigidity thanks to the large cylindrical face connection. While the force only acts on one side while tightening a thread due to the thread’s pitch, the new MAPAL system ensures a symmetrical insertion and good distribution of force.
 

Increased tool life and better machining quality

Together with the connection, MAPAL is also presenting a new tool holder design. The tool holder has a ring of cooling channel bores, which enables a much higher volume of cooling than conventional internal cooling is able to provide. By channelling the coolant directly to the area of the cutting edges, the tool life is extended and machining quality improved.

In addition, by doing away with a central cooling channel bore, the milling head becomes much more stable. The tool holder is 10 to 15% more rigid than comparable systems, resulting in higher achievable form and position tolerances, smoother processes and longer tool life.

The solid carbide replaceable heads from MAPAL also impress thanks to their high process reliability as inserts cannot become loose at high temperatures. If tool breakage does occur, the connection’s simple assembly ensures that the machining process can be resumed quickly.

Modular tool systems with a steel-shank tool holder have also been marketed to conserve carbide. With the bayonet connection, MAPAL is going one step further. Compared to previous connection, 70% less material is used, in keeping with the trend towards more sustainability.

Diverse range of applications

Die Trennstelle wird in sieben verschiedenen Größen mit Kopfdurchmessern von 11,8 mm bis 22,5 mm und in Kopflängen bis 1xD angeboten, was eine Vielzahl von Anwendungen ermöglicht. Neben den Wechselköpfen kann der Werkzeughersteller auch die Halter individuell gestalten, um so zum Beispiel die Kühlmittelzufuhr für bestimmte Anforderungen zu optimieren. 

Zusammen mit der Bajonett-Trennstelle hat MAPAL auf der AMB zwei weitere, erste Anwendungen vorgestellt. Ein fünfschneidiger Vollhartmetallkopf wird von Kunden aus der Automobilindustrie als Kugelbahnfräser in der Fertigung homokinetischer Gelenke eingesetzt werden. Die Weichbearbeitung dieser im Antriebsstrang verbauten Teile verlangt hohe Genauigkeit. Ein weiteres Werkzeug ist ein Formfräser zur Bearbeitung von Kalotten an Antriebswellen.
