Grade Details — Key Grade Characteristics
The SGM08548 is manufactured from Ultra-Fine Micro-Grain Carbide with an advanced AlTiN Nano-Layered PVD coating, designated as grade PR1535. This combination delivers exceptional wear resistance, thermal stability, and edge retention under high-speed machining conditions.
| Property | Value | Performance Impact |
|---|---|---|
| Hardness | 93.5 HRA | Superior wear resistance in hard materials |
| TRS (Transverse Rupture Strength) | 4,200 MPa | High resistance to chipping and fracture |
| Grain Size | 0.5 μm | Mirror-finish surface quality |
| Coating Thickness | 2.5 μm | Extended tool life without edge rounding |
| Oxidation Temperature | 1,100°C | Stable performance in dry machining |
Grade Comparison Matrix
| Grade | Coating | Best For | Speed | Finish |
|---|---|---|---|---|
| PR1535 (This Tool) | AlTiN Nano | Steel, Stainless, Titanium | ★★★★★ | ★★★★★ |
| PR1425 | TiAlN | General Steel | ★★★★☆ | ★★★★☆ |
| PR1215 | TiCN | Low-carbon Steel | ★★★☆☆ | ★★★☆☆ |
| PR1635 | Diamond-like Carbon | Aluminum, Copper | ★★★★★ | ★★★★★ |
Chipbreaker Profile
Although the SGM08548 is an endmill rather than an indexable insert, its flute geometry incorporates advanced chipbreaker principles optimized for micro-machining. The variable helix flute design with polished rake surfaces creates controlled chip curl and evacuation, preventing recutting and built-up edge (BUE) in deep cavity work.
| Flute Feature | Specification | Benefit |
|---|---|---|
| Rake Angle | 8° positive | Reduced cutting forces, lower heat |
| Flute Polishing | Mirror finish (Ra 0.05 μm) | Prevents chip welding, extends life |
| Core Thickness | 65% of diameter | High rigidity, reduced deflection |
| Helix Variation | 30° ± 2° | Vibration damping, smooth finish |
Recommended Applications & Workpiece Materials
The SGM08548 is optimized for the following material groups and application types:
| Material Group | Examples | Suitability | Notes |
|---|---|---|---|
| Carbon Steel | 1045, 4140, 4340 | ★★★★★ | Excellent chip control, long life |
| Stainless Steel | 304, 316, 17-4PH | ★★★★☆ | Use with coolant for best results |
| Tool Steel | H13, D2, A2 | ★★★★☆ | Reduce speed 15% vs carbon steel |
| Titanium Alloys | Ti-6Al-4V, Ti-5Al-5V | ★★★☆☆ | High-feed strategy recommended |
| Aluminum Alloys | 6061, 7075, 2024 | ★★★★☆ | Polished flutes prevent BUE |
Application Map by Operation
| Operation | Suitability | Recommended Parameters | Result |
|---|---|---|---|
| Slotting | ★★★★☆ | ap = 0.5×D, ae = 1.0×D | Stable, low vibration |
| Profiling / Side Milling | ★★★★★ | ap = 1.0×D, ae = 0.3×D | Excellent surface finish |
| Pocketing | ★★★★☆ | Trochoidal path, 5-8% stepover | Long tool life, minimal wear |
| Plunge Drilling | ★★★☆☆ | Reduce feed to 60%, peck cycle | Acceptable with care |
| 3D Contouring | ★★★★★ | Constant tool load, smooth toolpath | Mirror finish on molds |
Recommended Cutting Conditions
| Material | Vc (m/min) | fz (mm/tooth) | ap max | ae max | Coolant |
|---|---|---|---|---|---|
| Carbon Steel (< 45 HRC) | 50-70 | 0.004-0.008 | 1.0 x D | 0.5 x D | Air / MQL |
| Stainless Steel (< 35 HRC) | 40-55 | 0.002-0.005 | 1.0 x D | 0.5 x D | Flood / MQL |
| Aluminum Alloys | 140-200 | 0.007-0.015 | 1.0 x D | 0.5 x D | Air / Compressed Air |
| Hardened Steel (45-55 HRC) | 40-55 | 0.004-0.008 | 0.3 × D | 0.2 × D | MQL / Oil Mist |
Operating Guidelines
- Run-out Check: Ensure total indicated run-out (TIR) at the tool tip is < 0.005 mm. Excessive run-out dramatically reduces tool life in micro-machining.
- Ramping: When entering material, use a ramp angle ≤ 2° or employ helical interpolation to minimize shock loading on the corner radius.
- Chip Evacuation: Use through-spindle coolant (TSC) at ≥ 70 bar for holes/deep pockets, or compressed air at 6 bar for shallow features.
- Tool Overhang: Keep tool overhang (L/D ratio) ≤ 4 for best results. If L/D > 6 is unavoidable, reduce cutting parameters by 30%.
- Spindle Warm-up: Warm up the spindle for 10 minutes at 10,000 RPM before precision operations to minimize thermal drift.
- Workholding: Rigid workholding is essential. Use minimum 3-point clamping and ensure fixture resonance frequency is above 2× spindle speed.
Toolholder Compatibility
The SGM08548 features a cylindrical shank designed for precision collet and hydraulic toolholders. Recommended clamping systems:
| Toolholder Type | Accuracy | Best Application | Notes |
|---|---|---|---|
| ER Collet (ER11, ER16) | ≤ 0.010 mm | General milling | Use high-precision collet (AA grade) |
| Hydraulic Chuck | ≤ 0.003 mm | High-speed finishing | Excellent damping, premium choice |
| Shrink Fit | ≤ 0.003 mm | Aggressive roughing | Maximum torque transmission |
| Milling Chuck | ≤ 0.008 mm | Heavy-duty milling | Good gripping force, moderate cost |
