Key Features and Benefits
Advanced MS Chipbreaker Technology
The MS chipbreaker design is specifically engineered for stainless steel applications. This geometry prevents work hardening during interrupted cuts and ensures reliable chip control across a wide range of cutting conditions. The optimized chipbreaker profile minimizes cutting forces while maintaining excellent surface finish quality.
US735 PVD Coating System
The US735 grade features a multi-layer PVD (Physical Vapor Deposition) coating that provides exceptional wear resistance and thermal stability. This coating system combines high hardness with excellent toughness, making it ideal for machining stainless steels, heat-resistant alloys, and other challenging materials.
55° Rhombic Geometry Advantages
The DNMG shape offers four usable cutting edges, providing excellent cost-effectiveness. The 55° included angle creates a strong cutting edge that can withstand higher cutting forces compared to sharper geometries, making it suitable for both roughing and finishing operations.
Recommended Applications
- Stainless Steel Machining: Austenitic, martensitic, and duplex stainless steels
- Interrupted Cutting Operations: Components with keyways, slots, or cross-holes
- Difficult-to-Machine Materials: Heat-resistant alloys and titanium alloys
- General Purpose Turning: Carbon steels, alloy steels, and cast irons
- CNC Lathe Operations: Both roughing and finishing applications
- Industrial Automation Systems: Integration with PLC-controlled machining centers
Optimal Cutting Parameters
| Material Type | Cutting Speed (m/min) | Feed Rate (mm/rev) | Depth of Cut (mm) |
|---|---|---|---|
| Stainless Steel (200HB) | 80-120 | 0.15-0.30 | 0.5-3.0 |
| Carbon Steel | 150-250 | 0.20-0.40 | 1.0-4.0 |
| Alloy Steel | 100-180 | 0.15-0.35 | 0.5-3.0 |
