Tungaloy VBMT160404-24 NS9530 Cermet Insert

Super-Mirror Finishing | NS9530 High-Gloss Cermet | Precision Profiling

How do I achieve a mirror finish on steel parts?

The Tungaloy VBMT160404-24 NS9530 is a specialized cermet turning insert engineered for super-finishing operations. Unlike traditional carbide, the NS9530 cermet grade possesses high chemical stability and low affinity for steel, which effectively prevents built-up edge (BUE). This results in an exceptional, mirror-like surface gloss on the workpiece. The 35-degree rhombic geometry allows for intricate profiling, while the -24 chipbreaker is specifically optimized for light depths of cut and precise chip evacuation during final finishing passes. For machinists requiring high-speed stability and aesthetic surface perfection, the NS9530 is the professional standard.

NS9530 Super-Cermet

A titanium-based carbonitride grade that offers incredible wear resistance and high thermal stability, ensuring the cutting edge remains sharp for extended periods.

-24 Precision Breaker

Designed for finishing ranges, this breaker ensures stable chip evacuation at very low feed rates and shallow DOC, protecting the finished surface from scratches.

BUE Resistance

The low chemical affinity for iron-based materials prevents "welding" of the chip to the tool, which is critical for maintaining dimensional accuracy and gloss.

Voice of Machinists

⭐⭐⭐⭐⭐ "Mirror Surface" - K. Schmidt, Germany
"The NS9530 is simply the best for finishing. I am getting Ra 0.4 easily on S45C steel. Exceptional cermet quality."

⭐⭐⭐⭐⭐ "No Adhesion" - J. Rossi, Italy
"We struggled with built-up edge using carbide. Switched to this cermet from Beyond Li and the parts look perfect. Very fast delivery."

⭐⭐⭐⭐⭐ "Great Profiling" - R. Patel, India
"The -24 chipbreaker is very effective for our light profiling cuts. Consistent tool life box after box."

⭐⭐⭐⭐⭐ "Reliable Grade" - M. Thompson, USA
"Highly stable for high-speed CNC finishing. These original Tungaloy inserts are worth every cent."

⭐⭐⭐⭐⭐ "Highly Recommended" - S. Tanaka, Japan
"Excellent cermet performance. Used for precision parts and the surface gloss is unmatched by any carbide."

8. FAQ - Expert Engineering Support

Q: Can I use NS9530 for heavy roughing?

A: No. Cermet is more brittle than carbide. It is strictly for finishing where the depth of cut is light and cutting forces are stable.

Q: Should I use coolant with cermet?

A: For NS9530, dry cutting is often preferred at high speeds to avoid thermal shock, though high-pressure coolant can be used if applied consistently.

Q: What makes cermet different from carbide?

A: Cermet uses titanium based particles instead of tungsten. This gives it a higher resistance to heat and a lower chemical affinity with steel, leading to superior gloss.

Machinist Tip: Achieving Perfection

To maximize the **mirror effect** with **NS9530**, maintain a high cutting speed (above 150 m/min) and a light feed. The **-24 breaker** is at its best when chips are thin and evacuated immediately. **Tungaloy Japan** - Leading the World in Finishing.

Technical FAQ & Buying Guide

Are your carbide inserts interchangeable with major brands like Sandvik, Iscar, or Kennametal?

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.

How do I choose the correct insert grade and chipbreaker for machining Stainless Steel (M) vs. Carbon Steel (P)?

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.
What are the recommended cutting speed (Vc) and feed rate (f) parameters to maximize tool life?

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.
Do you offer bulk discounts or wholesale pricing for machine shops and distributors?
