- H-Class (Tough Sub-micron Carbide - e.g., BY3030): Engineered for pre-hardened steels and mold inserts up to 45 HRC.
- M/K-Class (Corrosion-Resistant Matrix): Suitable for austenitic stainless steels and ductile cast irons.
7. Why Choose BEYOND CNC Tools
8. Frequently Asked Questions (FAQ)
Q: Are LOGU030310ER-GM inserts included with this 20mm high-feed milling arbor?
A: No. The arbor is supplied as a standalone tool body. Compatible LOGU030310ER-GM inserts must be ordered separately.
Q: What holder size is required for the MFH03R C19-20-200L-3T?
A: It features a 19mm straight cylindrical shank (C19) and fits standard 19mm milling collet chucks or hydraulic holders.
Q: How does the 200mm long reach affect stability during deep pocketing?
A: By combining high-feed low depth-of-cut mechanics with a rigid 19mm alloy steel body, axial forces are prioritized to minimize harmonic chatter in deep cavities.
Technical Tips & Troubleshooting Summary
Grade Comparison: Select tough PVD grades for interrupted cuts; use specialized micro-grain substrates for high-speed mold finishing.
Equivalent Models: Interchangeable with standard ISO high-feed arbors utilizing 19mm shank and LOGU0303 pocket configurations.
Troubleshooting Chatter: If harmonic vibration occurs with the 200mm reach, reduce radial engagement ($a_e$) or ensure a minimum of 50mm shank clamping depth.
Compliance & Authoritative Backing: Engineered under ISO 9001 and ANSI B94.55M structural frameworks. Validated through empirical industrial metalworking trials.
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.
