Description

MRMN Grooving Inserts for Steel and Stainless Steel

MRMN Grooving Inserts for Steel and Stainless Steel are the full-radius grooving indexable inserts for radius grooves, profile cuts, and rounded transitions in the P and M material groups. The cutting edge is designed as a radius across the entire width – this allows half-circles, O-ring grooves, or rounded run-out radii to be machined in a single pass.

The positive insert geometry reduces the radial cutting force, which prevents vibrations when plunging into thin-walled workpieces. The CVD or PVD coating is matched to the ISO P/M range and delivers high wear resistance even under varying cutting loads. Clamping is performed in the MGEHR/L system; the radius is selected according to the required groove contour.

For profile cuts and radius grooves on steel and stainless steel parts, the MRMN is the matched full-radius grooving insert with high profile accuracy.

die Radiusstechplatten Radiusstechplatten gut

Für Radien und Nutenrundungen in Edelstahl brauchbar, Platten sitzen plan im Halter. Die Werkzeuggeometrie arbeitet in meiner Fertigung von Wellen und Gehäuseteilen gleichmäßig, Spanbruch funktioniert zuverlässig über verschiedene Vorschubwerte hinweg.

Radius-Stechplatten überzeugen

Sauber geschliffene Schneiden, der Radius ist genau und die Oberfläche wirkt fein. Für meine Arbeit in Stahl genau das Richtige, auch im Edelstahl zieht mir nichts und die Klemmung hält die Platten bombenfest.

Radius-Stechplatten im Werkzeugstahl

Ich setze die Radius-Stechplatten für saubere Einstiche mit Radius in 1.2344 ein. Die Übergänge kommen definiert, keine Ratterspur und die Platten halten auch bei gehärteteren Vorhärtern ordentlich durch. Gute Wahl.
