NX2525: Mirror-Finish Grade
NX2525 is a premium uncoated cermet grade. Cermets are chemically stable at high speeds, which prevents the built-up edge (BUE) that often ruins precision parts. This grade provides the highest gloss levels on the workpiece, making it the top choice for steel finishing turning where visual quality is critical.
F-Breaker: Micro-Finishing Geometry
The F-breaker is specifically designed for small depths of cut ($a_p$). It effectively breaks chips even at ultra-low feed rates, preventing "bird-nesting" on small bore turning or delicate outer diameters. The "L" indicates the Left-hand orientation for specific tool holder setups.
Technical Cutting Parameters
| Workpiece Material | Speed ($v_c$) | Feed Rate ($f$) | DOC ($a_p$) |
|---|---|---|---|
| Mild Steel | 150 - 300 m/min | 0.03 - 0.12 mm/rev | 0.1 - 0.8 mm |
| Alloy Steel | 120 - 250 m/min | 0.03 - 0.10 mm/rev | 0.1 - 0.6 mm |
Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
