Recommended Cutting Parameters
Optimized for CNC Lathe operations in stainless and alloy steels:
- Cutting Speed (Vc): 100 - 180 m/min (330 - 590 SFM)
- Feed Rate (f): 0.10 - 0.25 mm/rev (0.004 - 0.010 ipr)
- Depth of Cut (ap): 0.5 - 2.5 mm
*Note: Use high-pressure coolant for best results in gummy stainless steel.
Grade & Coating: US735 CVD Specialist
The US735 grade is a dedicated CVD (Chemical Vapor Deposition) coated carbide designed to combat the intense heat generated during medium turning of stainless steel. The multi-layer coating acts as a thermal barrier, protecting the sub-micron substrate from edge deformation and crater wear.
Optimized Chipbreaker Geometry
With its positive rake angle, the WCMT geometry significantly reduces cutting resistance and vibration. The 0.4mm corner radius provides a balance between edge strength and surface finish, preventing work hardening of the material surface during precision CNC machining.

Questions & Answers
Expert Tip: Carbide Grade Selection
For the best CNC productivity, pair the WCMT06T304 with rigid machine setups. If you are experiencing vibration, reduce the feed rate slightly before lowering the cutting speed to maintain the CVD coating's thermal efficiency.
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.
