Recommended Cutting Conditions
Starting parameters for KW10 grade on typical workpiece materials (adjust based on machine rigidity and setup):
| Material | Cutting Speed Vc (m/min) | Feed fn (mm/rev) | Depth of Cut ap (mm) |
|---|---|---|---|
| Gray Cast Iron | 120–200 | 0.08–0.20 | 0.5–2.0 |
| Aluminum Alloy | 200–400 | 0.05–0.25 | 0.1–1.5 |
| Copper / Brass | 150–300 | 0.06–0.20 | 0.2–1.5 |
| Titanium Alloy | 30–60 | 0.08–0.15 | 0.5–1.5 |
| Plastics / Composites | 200–500 | 0.05–0.30 | 0.1–2.0 |
Note: Values are starting recommendations. Optimize based on machine condition, workpiece rigidity, and required surface finish. Recommended for non-ferrous materials; dry cutting acceptable for cast iron.
Operating Guidelines
- Tool Overhang: Minimize overhang to prevent vibration and ensure stable cutting. Use the shortest possible toolholder.
- Insert Seating: Ensure the insert seat is clean and free of chips before clamping. Verify proper contact with the toolholder pocket.
- Cutting Fluid: Recommended for non-ferrous materials; dry cutting acceptable for cast iron. For aluminum and copper, clean coolant prevents built-up edge formation.
- Edge Preparation: The uncoated edge is ready to use. Do not attempt additional honing or edge preparation.
- Storage: Store inserts in original packaging away from moisture and corrosive environments. Temperature range: 10°C–30°C.
- Inspection: Visually inspect cutting edges before use. Discard inserts with visible chipping, cracks, or excessive wear.
Toolholder Compatibility
This insert is compatible with standard ISO Compatible turning holders. Recommended toolholder families include:
- Toolholder Series: Standard ISO toolholders
- Clamping System: Lever-lock or screw-clamp depending on toolholder design
- Insert Seat Angle: Must match insert clearance angle (7°)
- Hand Compatibility: Ensure toolholder hand matches insert hand (Neutral)
- Shank Size: Select based on machine turret and workpiece envelope (16mm–32mm common)
