Description

Boring Bar SVJCR/L 93°, Indexable Insert Holder

The SVJCR/L boring bar with a 93° approach angle is a contour-capable internal turning holder that combines clean shoulder turning in bores with the accessibility of a pointed VC indexable carbide insert. Where internal profiles, tight contour transitions, or right-angle internal shoulders are required, this boring bar exploits its geometric advantages – the 35° nose angle of the VC insert reaches areas that are no longer accessible with 55° or 80° geometries.

The 93° approach angle creates a subtle clearance angle between the minor cutting edge and the machined internal shoulder. This prevents friction contact, which at exactly 90° would inevitably lead to premature flank wear and pressure marks on the shoulder – the result is clean internal shoulders and longer insert life. The shank, made from heat-treated tool steel, provides the bending rigidity that during internal machining with long overhangs makes the difference between a clean surface and chatter marks. The screw clamping system secures the insert firmly and with precise positioning, so work can resume immediately after changing. Right-hand and left-hand versions allow the optimal machining strategy to be implemented depending on bore geometry and machine configuration.

The SVJCR/L boring bar is recommended for users who need to machine both internal shoulders and tight contour profiles in bores – wherever accessibility and shoulder quality come together in internal machining.

Scope of delivery: 1 SVJCR/L boring bar (without indexable carbide insert) incl. screw and wrench.

Note: The image shows the right-hand version (R).

VJ-Bohrstange 93 Grad

Spitzwinklige Konturen innen gelingen mit der Stange sauber, keine Probleme bei mittlerem Überhang. Schnittverhalten lässt Raum für höhere Vorschübe.

Bohrstange gut im Alltag

Schulterdrehen innen kein Thema, Klemmung wertig. Für mittlere Anforderungen voll brauchbar. Bin zufrieden mit der Verarbeitung. Schulterdrehen innen kein Thema, Klemmung wertig.

Bin absolut zufrieden damit

Standard-Bohrstange die ihre Arbeit zuverlässig macht, keine Überraschungen bisher.

Innenschulter-Drehhalter 93 Grad konturstark

Der Konturhalter-Halter bringt Schulterdrehen in Innenbohrungen in 42CrMo4 sauber durch, die VN-Platten halten die Position bei Vorschüben bis 0,25 mm/U stabil und die Wiederholgenauigkeit bleibt über mehrere Chargen konstant.

Bohrstange 93 Grad, vielseitig im Alltag

Dreht Innenkonturen sauber, Plattensitz ist fest und für Kopierarbeiten passt das Ganze bei mir wirklich gut. Auch bei wechselnden Werkstücken keine Umgewöhnung nötig.

Passgenauer Halter

Bin bisher zufrieden. Gleichmäßige Oberfläche, kein Rattern und sauber geschliffen. Hat sich bewährt.

Bohrstange VJ 93 Grad solide im Segment

Das Werkzeug für enge Innenkonturen ist preislich in Ordnung, mittlerer Überhang kein Problem.

93° mit rhombischer Platte sauber

Für Innen-Schlichtaufgaben passt die Kombination. Der Halter hält sauber, Klemmung zieht ohne Spiel nach. Rundlauf bleibt auch bei längerer Auskragung im grünen Bereich. Oberfläche wird ansehnlich, Kante bleibt stabil. Solide Qualität zum Preis.

Noch etwas im Test

Innendrehen an Formhälften in 1.2312 läuft erstmal ordentlich. Die Klemmung arbeitet sauber und die Oberfläche kommt gleichmäßig. Für eine abschließende Bewertung fehlt mir noch die längere Betriebserfahrung.

Für Standard-Innenarbeiten einfach gut

Die klassische Winkelkombination für Innendrehen. Bohrstange ist stabil, Lauf ruhig. Bei Kleinserien und Reparaturen häufig im Einsatz.
