Applications & Features
Applications
Features
1. Application area
2. Grade properties
3. WavyJoint
New brazing technology for increased machining efficiency
- A maximum depth of cut up to 0.8 mm.
Reduces the number of passes to increase productivity. - Innovative WavyJoint brazing technology
Prevents the CBN tips from debrazing, eliminating abrupt insert fractures during demanding dry machining, while securing stable and predictable hard turning operations.
4. Hardbreakder Series
- HS chipbreaker
Optimized chipbreaker design for excellent chip control during hard turning at aggressive conditions - HP chipbreaker
Designed for finish machining of hardened parts with close tolerances - HF and HM chipbreakers
Suited for hard turning applications requiring great D.O.C. such as carburized layer removal
5. 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.
6. MiniForce-Turn Double-sided positive insert with CBN tips
MiniForce-Turn now offers WavyJoint CBN inserts that provide additional strength and security in aggressive cutting conditions.
