Description

Ausführung:

Entwickelt für den Einsatz mit sehr hohen Schnittgeschwindigkeiten. Hervorragend geeignet für Maschinen mit geringer Leistungsaufnahme und hohen Drehzahlen.
  • Deutliche Reduzierung der Schnittkräfte durch spezielle Schneidengeometrie.
  • Beschichtung für beste Verschleißbeständigkeit auch bei hohen Prozesstemperaturen.
  • Polierte Spannuten für guten Spanabfluss.

Eine schlanke Querschneide und die besondere Anordnung der 4 Führungsfasen bewirken eine hohe Positionier- und Fluchtungsgenauigkeit. Optimierte Mikrogeometrie für erhöhte Standzeit und Leistungsfähigkeit.

Hinweis:

Spannutenlänge LC = L2 + 1,5 × DC.
Ausführung HB und HE zum gleichen Preis wie HA lieferbar.
Form HB: mit Nr.122426 angeben.
Form HE: mit Nr.122425 + 129100HE bestellen.
