4. Grade Details — Key Grade Characteristics
The TA grade is a high-performance PVD-coated carbide specifically developed for general-purpose milling of steels and cast irons. It combines an ultra-fine grain carbide substrate with a multi-layer TiAlN coating to deliver balanced wear resistance, toughness, and thermal stability.
| Property | Specification |
|---|---|
| Coating Type | TiAlN-based PVD multi-layer |
| Carbide Substrate | Ultra-fine grain cemented carbide (0.5μm) |
| Hardness | HRA 92.5 |
| Oxidation Temperature | 1,100°C |
| Coating Color | Bronze/Copper |
| Transverse Rupture Strength | ≥ 3,800 MPa |
5. Grade Comparison Matrix
| Grade | Coating | Wear Resistance | Toughness | Best For |
|---|---|---|---|---|
| TA | TiAlN PVD | ★★★★☆ | ★★★★☆ | General steel, cast iron |
| PR1225 | MEGACOAT PVD | ★★★★★ | ★★★☆☆ | High-speed finishing |
| PR1535 | MEGACOAT NANO | ★★★★★ | ★★★★☆ | Hardened steel >50 HRC |
| GW25 | Uncoated | ★★☆☆☆ | ★★★★★ | Aluminum, non-ferrous |
6. Chipbreaker Profile
The SGM02260 features a Optimized edge prep with corner chamfer for stability designed to optimize chip formation and evacuation during 4-flute milling operations. The edge geometry promotes controlled chip curling and breakage, reducing cutting forces and minimizing the risk of chip recutting — a common cause of poor surface finish and premature tool wear.
- Positive rake angle for reduced cutting force and improved chip flow
- Polished flute surface minimizes chip adhesion and built-up edge
- Optimized gash width for efficient chip pocket clearance
- Consistent edge prep ensures repeatable performance batch-to-batch
7. Recommended Applications & Workpiece Materials
Primary Applications: High-efficiency slotting, shouldering, and finishing of steel and cast iron
Compatible Materials (ISO Groups): Carbon Steel (P), Alloy Steel (P), Tool Steel (P), Gray Cast Iron (K), Nodular Iron (K)
| Material Group | Examples | Machinability |
|---|---|---|
| P – Steel | C45, 4140, 4340, SS400, S45C | ★★★★★ Excellent |
| M – Stainless Steel | 304, 316, 17-4PH, 15-5PH | ★★★★☆ Very Good |
| K – Cast Iron | GG25, GGG40, FC250, FCD500 | ★★★★★ Excellent |
| N – Non-Ferrous | Aluminum 6061, Brass, Bronze | ★★★☆☆ Good (dry recommended) |
8. Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| Slotting (ae = 1.0×Dc) | ★★★★☆ | Full slotting with stable chip control |
| Shouldering (ae = 0.5×Dc) | ★★★★★ | Optimal for side-wall finishing |
| Profiling / Contouring | ★★★★★ | High-precision edge tracking |
| Plunge Milling | ★★★☆☆ | Limited plunge capability; ramp entry recommended |
| Ramping | ★★★★☆ | Max ramp angle 3° recommended |
| High-Feed Machining | ★★★★☆ | Multi-flute design supports higher feed rates |
9. Recommended Cutting Conditions
| Parameter | Recommended Range | Optimal Starting Point |
|---|---|---|
| Cutting Speed (Vc) | 100–180 m/min | 140 m/min |
| Feed per Tooth (fz) | 0.03–0.10 mm/z | 0.06 mm/z |
| Axial Depth (ap) | 1.0–1.5 × Dc | 1.2 × Dc |
| Radial Depth (ae) | 0.05–1.0 × Dc | 0.5 × Dc |
| Coolant | External flood or air blast | Water-soluble emulsion (8–10%) |
10. Operating Guidelines
- Tool Runout: Maintain spindle runout ≤ 5 μm for optimal tool life and surface finish.
- Workpiece Fixturing: Ensure rigid clamping to prevent vibration and chatter, especially at high speeds.
- Coolant Application: Use adequate coolant flow directed at the cutting zone. For cast iron, dry machining is acceptable.
- Entry Strategy: Use helical or ramp entry for pocketing. Avoid direct 90° plunge unless center-cutting capability is confirmed.
- Chip Evacuation: Ensure efficient chip removal to prevent recutting and heat buildup. Compressed air is effective for shallow cuts.
- Tool Inspection: Inspect cutting edges before each use. Do not use tools with chipped or worn edges.
- Speed/Feed Adjustment: Reduce cutting speed by 15–20% when machining stainless steel or heat-resistant alloys.
11. Toolholder Compatibility
| Holder Type | Compatibility | Notes |
|---|---|---|
| Hydraulic Chuck | ★★★★★ | Best damping; ideal for finishing |
| Shrink Fit Holder | ★★★★★ | Maximum rigidity and concentricity |
| ER Collet Chuck | ★★★★☆ | Widely available; use precision collets |
| Milling Chuck | ★★★★☆ | Good for general-purpose applications |
| Weldon Flat Holder | ★★★☆☆ | Ensure set screw does not damage shank |
