Tungaloy CCMT060204-PS NS9530 Turning Insert

Mirror Surface Quality | High-Speed Finishing | Premium NS9530 Cermet Grade

How does the NS9530 Cermet grade achieve such high surface quality?

The Tungaloy CCMT060204-PS NS9530 is a specialized uncoated cermet turning insert engineered for machinists who demand perfection in surface finish and dimensional accuracy. The NS9530 grade is a titanium-based cermet that provides an exceptional balance of wear resistance and fracture toughness. Because cermet has a low affinity for steel workpieces, it virtually eliminates built-up edge (BUE), ensuring a polished, "mirror-like" finish on carbon and alloy steels. This indexable turning tool features the PS-style chipbreaker, a ground geometry designed specifically for light finishing to semi-finishing passes. With a standard 0.4mm corner radius, it offers higher edge strength than smaller radii while maintaining the precision required for high-end CNC machining. Made in Japan, it is the ultimate precision machining solution for high-speed automated production.

Is NS9530 better than coated carbide for finishing?

For high-speed steel finishing, the NS9530 cermet grade often outperforms coated carbide. Because cermet is chemically stable and heat-resistant, it doesn't suffer from the "sticking" issues that cause rough surface finishes. This long-tail keywords industry favorite is specifically designed to provide long-lasting dimensional accuracy. For precision machining, NS9530 maintains its razor-sharp edge even at the high temperatures generated by increased cutting speeds, resulting in a significantly longer tool life during light finishing passes in CNC machining.

PS Chipbreaker: Optimized for Chip Control

The PS Chipbreaker is a precision-ground finishing geometry. It features a sharp rake angle that reduces cutting resistance and heat generation. This is crucial for avoiding vibration in small boring bars or thin-diameter workpieces. This indexable turning tool ensures that chips are broken into small, manageable pieces even at shallow depths of cut, preventing scratches on the workpiece surface.

What are the recommended feeds and speeds for NS9530?

Best suited for P (Steel) and K (Cast Iron) finishing:

• Cutting Speed (Vc): 100 - 300 m/min (High speed is key for Cermet)
• Feed Rate (f): 0.05 - 0.15 mm/rev
• Depth of Cut (ap): 0.2 - 1.5 mm

*Note: Cermet is more brittle than carbide; avoid heavy interruptions and ensure a rigid setup for best results.*
