ZCC.CT CCMT060204-53 YBC351: Heavy-Duty Steel Turning Solutions
Product Overview
The ZCC.CT CCMT060204-53 YBC351 is a powerhouse in the P-group (Steel) category. Engineered with the YBC351 grade—featuring a thick TiCN and Al2O3 CVD coating—it excels in roughing and heavy-duty machining. The 53 chipbreaker geometry is specifically designed for high-strength edges, ensuring stable chip breaking even during interrupted cuts or varying depths of cut.
Key Features
- YBC351 Grade: High-toughness substrate combined with advanced CVD coating for maximum impact resistance.
- 53 Chipbreaker: Optimized for roughing operations, providing a strong cutting edge and excellent chip control.
- Superior Heat Resistance: Thick Al2O3 layer protects against thermal deformation during high-speed dry cutting.
- Optimized for P30-P40: Ideal for carbon steel, alloy steel, and cast steel machining.

FAQ - Technical Support
Q: What is the primary difference between YBC251 and YBC351?
A: YBC351 is specifically engineered for higher toughness and rougher cutting conditions compared to the medium-duty YBC251.
Q: Is this insert suitable for dry machining?
A: Yes, the CVD coating provides excellent thermal protection for dry cutting of steel materials.
Q: Can I use the 53 chipbreaker for finishing?
A: The 53 geometry is optimized for roughing. For high-precision finishing, we recommend ZCC.CT's 'HF' or 'XF' chipbreakers.
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.
