Application Map by Operation
Understand where the DNMG150412PG delivers maximum value across common turning operations:
| Operation Type | Suitability | Recommended Conditions | Notes |
|---|---|---|---|
| External Turning | ★★★★★ Excellent | 0.5 – 3.5 mm / 0.12 – 0.45 mm/rev | Primary application |
| Internal Turning | ★★★★☆ Very Good | Reduce speeds by 10-15% | Use with appropriate boring bars |
| Facing | ★★★★☆ Very Good | Light DOC preferred | Mind center-line exit |
| Profiling / Copying | ★★★☆☆ Good | Reduce feed at small radii | Nose radius dependent |
| Grooving / Parting | ★☆☆☆☆ Not Recommended | — | Use dedicated grooving inserts |
| Threading | ☆☆☆☆☆ Not Applicable | — | Use dedicated threading inserts |
Recommended Cutting Conditions
Parameters below are starting recommendations for stable setups with short overhangs. Adjust based on machine rigidity, coolant delivery, and workpiece stability:
| Workpiece Material | Hardness (HB) | Cutting Speed Vc (m/min) | Feed fn (mm/rev) | Depth of Cut ap (mm) |
|---|---|---|---|---|
| Carbon Steel (C35, C45) | 125 – 190 | 150 – 250 | 0.10 – 0.40 | 0.5 – 3.0 |
| Alloy Steel (42CrMo4) | 180 – 280 | 150 – 220 | 0.10 – 0.40 | 0.5 – 3.0 |
| Tool Steel (H13, D2) | 200 – 350 | 130 – 200 | 0.10 – 0.35 | 0.5 – 3.0 |
| Bearing Steel (100Cr6) | 220 – 300 | 120 – 190 | 0.10 – 0.32 | 0.5 – 3.0 |
Operating Guidelines
- Coolant Strategy: CA515 performs well under both wet and dry conditions. For best surface finish, use high-pressure coolant directed at the cutting edge.
- Speed Selection: Start at the lower end of the recommended Vc range for unstable setups or long overhangs. Increase gradually once stability is confirmed.
- Feed Rate: Maintain consistent feed to avoid built-up edge (BUE). For finishing operations, do not exceed the upper feed limit of the chipbreaker.
- Depth of Cut: Medium Machining chipbreaker is optimized for 0.5 to 3.5 mm mm depth. Exceeding this range may compromise chip control and edge life.
- Toolholder Overhang: Minimize overhang to reduce vibration. For internal turning, use dampened boring bars when L/D exceeds 4:1.
- Edge Preparation: This insert features a precision-honed edge (T-land + hone) optimized for steel. Do not re-grind or alter the edge geometry.
- Insert Seat Condition: Ensure the toolholder seat is clean and undamaged. A worn seat reduces contact area and promotes thermal cracking.
- Replacement Criteria: Monitor flank wear (VB). Replace when VB reaches 0.3 mm for roughing or 0.15 mm for finishing to maintain dimensional accuracy.
Toolholder Compatibility
The DNMG150412PG is a 0° clearance (N-type) insert with a 5/8" inscribed circle. It seats securely in the following standard holder families:
| Holder Style | Compatible Designation | Approach Angle | Application |
|---|---|---|---|
| External Turning | DDJNR / DDJNL 2020K15 | 93° | General external turning |
| External Turning | DDJNR / DDJNL 2525M15 | 93° | Heavy-duty external turning |
| Internal Boring | S16Q-SDUCR11 | 93° | Internal diameter boring |
| Internal Boring | S20R-SDUCR11 | 93° | Rigidity-optimized internal |
| Screw-Clamp | MDJNR / MDJNL 2020K15 | 93° | High-security clamping |
Important: Use holders with matching insert size (15 = 5/8" I.C.) and ensure the seat angle is compatible with 0° clearance (N-type) inserts. Verify chipbreaker clearance in the holder pocket before operation.
