F7030 Multi-Phase Coating
The F7030 grade is a specialized CVD coated carbide. It utilizes a fibrous TiCN and micro-grain Al2O3 layer that provides industry-leading wear resistance and thermal shock resistance. This prevents the growth of thermal cracks during wet cutting, making it ideal for high-impact alloy steel milling.
JS Chipbreaker Geometry
The JS Chipbreaker is a finishing-to-light-medium geometry. It features a sharp cutting edge that significantly reduces cutting resistance. This prevents burr generation and heat buildup, ensuring an excellent surface finish on carbon steels and difficult-to-cut stainless alloys.
Recommended Cutting Parameters
General Application for Steel & Stainless (F7030)
| Material Group | Cutting Speed ($v_c$) | Feed per Tooth ($f_z$) | Depth of Cut ($a_p$) |
|---|---|---|---|
| Mild Steel / SS400 | 200 - 300 m/min | 0.10 - 0.25 mm/t | 0.5 - 2.5 mm |
| Alloy Steel / SCM440 | 150 - 250 m/min | 0.15 - 0.35 mm/t | 0.5 - 3.0 mm |
| Stainless Steel (SUS304) | 100 - 180 m/min | 0.10 - 0.20 mm/t | 0.5 - 2.0 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.
