SPCG53Z NX2525
Mitsubishi Materials | The Mirror-Finish Cermet Authority
The Mitsubishi SPCG53Z NX2525 is a high-performance cermet milling insert specifically engineered for high-speed finishing operations. Utilizing the NX2525 grade, this insert combines the hardness of ceramic with the toughness of metal binders to deliver exceptional surface quality and dimensional accuracy. It is the definitive choice for dry milling of carbon steel, alloy steel, and cast iron when a mirror-like finish is required.

NX2525: Cermet Excellence
The NX2525 grade is a premium uncoated cermet. It features an optimized microstructure with highly hardened Ti (Titanium) compound particles. This provides the insert with excellent resistance to plastic deformation and adhesion (built-up edge). Unlike traditional carbide, NX2525 excels in high-speed finishing, maintaining sharp edges and producing superior surface gloss on steel workpieces.
Wiper Effect Geometry
The "Z" in SPCG53Z indicates a specialized geometry often used for wiper finishing or specific edge preparation. This design ensures that the feed marks are minimized, allowing for extremely low $Ra$ values. It is ideal for dry cutting conditions where chip welding must be avoided to preserve the integrity of the finished surface.
Recommended Cutting Parameters
| Workpiece Material | Cutting Speed ($v_c$) | Feed per Tooth ($f_z$) | Condition |
|---|---|---|---|
| Low Carbon Steel | 250 - 300 m/min | 0.15 - 0.25 mm/t | Dry Only |
| Alloy Steel (4140) | 150 - 220 m/min | 0.10 - 0.20 mm/t | Dry Only |
| Gray Cast Iron | 130 - 200 m/min | 0.12 - 0.25 mm/t | Dry Only |
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.
