Useful CBN insert with unique shape
For high efficiency in finishing hardened steel, cast iron and sintered metal
Applications & Features
Applications
Features
New CBN inserts for general turning
- GNGA insert with 70° corner angle
- FNGA insert with 45° corner angle
- Smaller corner angle provides the insert with greater clearance between the insert flank and workpiece surface, allowing better chip flow and evacuation.
- Enables greater D.O.C. in face turning applications in which the insert is pulled outward (fed away from the workpiece center).
- YNGA insert with 25° corner angle
- Allows undercutting, V grooving, and other applications that are not possible with traditional V inserts.
High versatility
- Existing ISO turning toolholder can be used for these inserts.
- For GNGA insert: Use the holder for CNxx1204 insert
- For FNGA insert: Use the holder for DNxx1504 insert
- For YNGA insert: Use the holder for VNxx1604 insert
- No offsets needed compared to ISO inserts, due to same geometry of cutting edge position.
- Double sided insert with 2 cutting edges.
