MRMN-M Grooving Inserts for Full-Radius Grooving and Profile Turning of Steel and Stainless Steel

The MRMN-M grooving insert has been specially developed for precise full-radius grooving and profile turning. Its advanced AlTiSi nanocomposite PVD coating provides extreme hardness, excellent oxidation resistance, and high thermal stability – ideal for machining steel, stainless steel, and cast iron. The coating’s low friction coefficient minimizes built-up edge formation, ensuring smooth chip flow and excellent surface finishes.

The tough substrate provides high cutting-edge stability and fracture resistance, making the MRMN-M highly reliable even under variable cutting conditions and interrupted cuts. Its full-radius cutting edge enables the precise production of round grooves, sealing surfaces, and profiled transitions with outstanding dimensional accuracy. The optimized chipbreaker geometry ensures efficient chip evacuation, even at high feed rates and small cutting depths.

Thanks to its balanced combination of wear resistance and toughness, the MRMN-M delivers consistent tool life and excellent process reliability. It is the ideal choice for precise and cost-efficient full-radius grooving and profile machining in professional metal-cutting environments.

Radius-Stechplatten feinschneidend

Vollradius-Stechplatten für Profildrehen. Bei Sonderaufträgen mit definierten Radien unverzichtbar. Schneide hält gut. Rüstzeit bleibt kurz, Ergebnisse sind präzise. Bei Kleinserien mit wiederkehrenden Radien bei uns seit Monaten im täglichen Einsatz.

Radius-Stechplatten M in Stahl

Vollradius-Einstechen und Profildrehen, Radien bleiben präzise. Werde die Sorte weiter nutzen. Werde das Werkzeug langfristig in meiner Fertigung einsetzen, die Ergebnisse sind dauerhaft ok und die Nutzung wirklich unkompliziert. Alles in allem eine gute Qualität und der Lieferung.

Vollradius-Stechplatte praktisch

Für Freistiche und Rundungen in Stahl wirklich praktisch. Oberfläche wird richtig rund, ohne dass man großartig programmieren muss. Kante bleibt stabil, Spanbruch funktioniert zuverlässig. Für Vollradius-Profile eine verlässliche Verbrauchsplatte, bin zufrieden.

Vollradius-Stechen sauber

Die Radiusstechplatten erlauben mir saubere Vollradien an Formrohlingen in 1.2312. Die Übergänge sind gleichmäßig, die Breite hält und der Span bricht kontrolliert. Empfehlenswert.
