NX2525 Cermet Grade
The NX2525 grade is a titanium-based cermet that provides high hardness and low affinity for steel workpieces. Unlike standard carbide, it resists "smearing" or material welding at high speeds. This ensures that the indexable turning insert maintains a sharp edge, resulting in superior surface brightness and dimensional accuracy.
F Chipbreaker (Fine Machining)
The F chipbreaker is specifically optimized for precision turning at light depths of cut. Its geometry forces tight chip curls even in ductile steels, ensuring chip evacuation is seamless and the workpiece surface remains unscratched during high-speed finishing passes.
Recommended Cutting Data
| Material Group | Speed ($v_c$) | Feed per Rev ($f$) | DOC ($a_p$) |
|---|---|---|---|
| Carbon Steel (Soft) | 250 - 500 m/min | 0.05 - 0.20 mm/rev | 0.2 - 1.2 mm |
| Alloy Steel (Hardened) | 150 - 350 m/min | 0.05 - 0.15 mm/rev | 0.1 - 1.0 mm |
