Chipbreaker Profile
The SGM series employs a precision-ground chipbreaker geometry optimized for 3-flute ball nose endmills. The unique flute profile ensures:
- Progressive Chip Thinning: Variable helix design reduces chatter and harmonics during high-speed machining.
- Enhanced Chip Evacuation: Wide, polished flutes prevent chip recutting and built-up edge (BUE) formation.
- Stable Cutting Edge: Micro-land edge preparation (T-land) provides robust edge strength for interrupted cuts.
- Surface Finish Optimization: Polished rake faces minimize friction, delivering mirror-quality surface finishes on contoured surfaces.
Recommended Applications & Workpiece Materials

| Carbon Steel (< 0.5% C) | P1.1 | Excellent | PR1225 / PR1705 |
| Alloy Steel (> 0.5% C) | P2.0 | Good | PR1225 / PR1535 |
| Stainless Steel (Austenitic) | M1.0 | Moderate | PR1535 |
| Cast Iron (Gray / Nodular) | K2.0 | Good | PR1705 |
| Hardened Steel (45-65 HRC) | H1.0 | Challenging | PR1535 |
| Titanium Alloys | S1.0 | Difficult | PR1535 |
Application Map by Operation
| Operation | Suitability | Optimal Conditions | Notes |
|---|---|---|---|
| 3D Contouring | ★★★★★ | High-speed finishing | Best for complex mold cavities |
| Slot Milling | ★★★☆☆ | Light to medium depths | Use reduced ae for deep slots |
| Ramping | ★★★★☆ | Angle ≤ 15° | Excellent chip evacuation |
| Plunging | ★★★☆☆ | Center-cutting capable | Reduce feed by 50% |
| Profiling | ★★★★★ | Full radial engagement | Ideal for thin-wall features |
Recommended Cutting Conditions
| Parameter | Value Range | Unit | Notes |
|---|---|---|---|
| Cutting Speed (Vc) | 80-120 | m/min | Adjust for material hardness |
| Feed per Tooth (fz) | 0.002-0.005 | mm/tooth | Start at lower end for finishing |
| Axial Depth (ap) | 0.3-0.8 | mm | Up to 1.5x DC for roughing |
| Radial Depth (ae) | 0.05-0.15 | mm | 0.05-0.2x DC for finishing |
| Spindle Speed (n) | 25,000-40,000 | RPM | Depends on machine capability |
Operating Guidelines
- Runout Control: Maintain tool runout below 0.005 mm (0.0002") for optimal tool life and surface finish. Use precision collets or hydraulic chucks.
- Coolant Strategy: For steel and stainless steel, use high-pressure coolant (70+ bar) directed at the cutting edge. For cast iron, dry machining or minimal quantity lubrication (MQL) is preferred.
- Entry Method: Use helical or ramp entry paths. Avoid direct plunging into solid material; reduce feed rate by 50% during entry.
- Tool Overhang: Minimize tool overhang to reduce deflection. Use the shortest possible tool length for the application.
- Edge Inspection: Inspect cutting edges under magnification after every 2 hours of cutting time. Replace at first sign of coating wear or edge chipping.
- Workpiece Fixturing: Ensure rigid workpiece clamping to prevent vibration. Dampened toolholders are recommended for L/D ratios exceeding 4:1.
