SEEN1203AFTN YNG151: The Ultimate Cermet Solution for Mirror Finishing
Product Overview
The SEEN1203AFTN YNG151 is a high-performance cermet milling insert engineered by ZCC.CT. Unlike standard carbide, the YNG151 Cermet grade combines the toughness of ceramic with the metallic binder of titanium, offering exceptional chemical stability and low affinity for workpiece materials. This ensures a mirror-like surface finish and prevents built-up edge (BUE) during light roughing to high-speed finishing of steel and cast iron.
Why Choose YNG151 Cermet?
- ✔ Superior Surface Quality: Low friction coefficient ensures extremely low surface roughness (Ra) on the workpiece.
- ✔ Extreme Oxidation Resistance: Maintains hardness at higher temperatures where traditional carbide fails.
- ✔ High Dimensional Accuracy: Excellent wear resistance ensures tool consistency during long production runs.

— Sato T., Japan 🇯🇵Frequently Asked Questions
Q: Why use Cermet (YNG151) instead of Tungsten Carbide?
A: Cermet has lower affinity for iron-based metals, which means less sticking (BUE) and much better surface gloss compared to carbide.
Q: Can SEEN1203AFTN handle heavy roughing?
A: No, Cermet is more brittle than carbide. It is strictly designed for high-speed finishing and semi-finishing with small depths of cut.
Q: Is dry machining recommended?
A: Yes, Cermet performs exceptionally well in dry machining because it has high thermal stability and oxidation resistance.
Industrial Tech Tip: For the best results with YNG151, maintain a stable cutting speed. If you see chipping, reduce the feed rate per tooth (fz) but keep the speed (Vc) high to leverage the thermal properties of cermet.
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.
