Chipbreaker Profile
The SGM series features an optimized flute profile with variable helix geometry and polished rake surfaces to ensure efficient chip formation and evacuation. The 2-flute open-groove design minimizes chip recutting and reduces heat accumulation during deep slotting operations.
| Feature | Description |
|---|---|
| Rake Angle (γ) | +8° positive rake for reduced cutting forces |
| Flute Polishing | Mirror-polished flutes to prevent material adhesion |
| Core Design | Thickened tapered core for maximum rigidity |
| Edge Preparation | Micro-honed cutting edge (T-land 0.05 mm × 20°) |

|---|---|---|
| Carbon Steel | C45, C50, 1045, 1050 | Excellent |
| Alloy Steel | 42CrMo4, 4140, 4340 | Excellent |
| Stainless Steel | 304, 316, 17-4PH | Very Good |
| Cast Iron | GG25, GGG40, Class 40 | Good |
| Tool Steel | H13, D2, O1 (up to 45 HRC) | Good |
Application Map by Operation
| Operation | Suitability | Recommended Strategy |
|---|---|---|
| Slotting (full width) | ★★★★★ | 2-flute design ideal for full-engagement slotting |
| Side Milling | ★★★★☆ | Use ae ≤ 0.5 × DC for optimal surface finish |
| Plunge Milling | ★★★☆☆ | Center-cutting capable; reduce feed by 30% |
| Profiling / Contouring | ★★★★☆ | Excellent for 2D and 3D contouring operations |
| Roughing | ★★★★★ | High material removal rates with stable chip control |
| Finishing | ★★★★☆ | Achieves Ra 0.4–0.8 µm under optimal conditions |
Recommended Cutting Conditions
Parameters below are starting recommendations for alloy steel (42CrMo4 / 4140). Adjust based on machine rigidity and workpiece fixturing.
| Parameter | Roughing | Finishing |
|---|---|---|
| Cutting Speed (Vc) | 100 m/min | 150 m/min |
| Feed per Tooth (fz) | 0.036 mm | 0.024 mm |
| Axial Depth (ap) | 4.5 mm | 1.5 mm |
| Radial Depth (ae) | 2.4 mm | 0.9 mm |
| Spindle Speed (n)* | 10,610 rpm | 15,915 rpm |
| Table Feed (Vf)* | 763 mm/min | 763 mm/min |
*Calculated values for reference; actual spindle speed may be limited by machine capability.
Operating Guidelines
- Use high-pressure coolant (minimum 70 bar) for deep cavity work to ensure effective chip evacuation.
- Maintain tool overhang at ≤ 5 × DC for optimal rigidity and surface finish.
- Reduce feed rate by 20–30% when entering or exiting the workpiece to minimize burr formation.
- For stainless steel applications, use emulsion coolant with 8–10% concentration to prevent built-up edge.
- Inspect cutting edges after every 30 minutes of cutting time; replace tool if flank wear exceeds 0.15 mm.
- Store tools in original packaging away from moisture and corrosive atmospheres.
Toolholder Compatibility
| Holder Type | Compatibility | Recommendation |
|---|---|---|
| ER Collet Chuck | ER16 / ER20 / ER25 | Suitable for general milling; ensure TIR ≤ 0.01 mm |
