NX2525 Cermet Grade
The NX2525 grade is a specialized titanium-based cermet (ceramic-metal composite). It provides superior resistance to built-up edge (BUE) and crater wear. Unlike carbide, cermet has a low affinity for steel, making this indexable turning insert the premier choice for achieving high dimensional accuracy and exceptional brightness in the final pass.
Chipbreaker Technology
Standard TNMG geometry provides a balanced cutting edge for general-purpose stable turning. The double-sided design offers 6 usable cutting edges, maximizing cost-efficiency for high-volume CNC finishing applications. It excels in chip control across a wide range of feed rates.
Recommended Cutting Parameters
| Material Group | Cutting Speed ($v_c$) | Feed Rate ($f$) | Depth of Cut ($a_p$) |
|---|---|---|---|
| Carbon Steel / Alloy Steel | 150 - 350 m/min | 0.05 - 0.25 mm/rev | 0.2 - 2.0 mm |
| Stainless Steel (Finishing) | 100 - 250 m/min | 0.05 - 0.20 mm/rev | 0.2 - 1.5 mm |
