YBG102 PVD Grade Technology
The YBG102 grade is a specialized PVD nano-coated carbide material. It features an ultra-fine Nc-TiAlN coating combined with a high-strength substrate. This makes it ideal for finishing to semi-finishing of stainless steel and high-temperature alloys, offering incredible thermal stability and preventing notch wear.
EDR Geometry Performance
The EDR chipbreaker/geometry is designed for smooth chip evacuation and reduced cutting force. It is particularly effective for indexable milling cutters operating in aerospace and medical component manufacturing where precision is paramount.
Recommended Cutting Parameters
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (fz) |
|---|---|---|
| Stainless Steel (M Class) | 120 - 220 m/min | 0.10 - 0.25 mm/t |
| Heat Resistant Alloys (S Class) | 30 - 80 m/min | 0.08 - 0.20 mm/t |
Questions & Answers
A: Yes, the nano-AlTiN coating provides excellent heat resistance, allowing it to perform well in dry milling conditions for stainless steel.
A: It is primarily used for face milling and shoulder milling where high surface quality and dimensional accuracy are required.
Global Trust - Customer Feedback
Liam W. - United Kingdom
Outstanding performance on Inconel. Tool life in YBG102 is twice our previous brand.
Hans G. - Germany
We use these for finishing 316L parts. The SPCW 1204 dimensions are perfect every time.
Chen L. - Singapore
ZCC.CT provides the best cost-to-performance ratio for our CNC shop.
Mateo R. - Brazil
Fast chip evacuation and very low vibration during the milling process.
Sarah M. - USA
The YBG102 coating is very tough. Handles the heat of dry milling quite well.
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.
