ZCC.CT SNMG150612-15 YBC251 Roughing Turning Insert
Product Overview
"Which carbide turning insert is best for heavy roughing in steel while managing severe chip loads and thermal shock?"
The ZCC.CT SNMG150612-15 in YBC251 grade is a powerhouse industrial turning insert specifically designed for stable roughing and heavy roughing of steel (ISO P) and cast iron (ISO K). Its defining feature is the rugged -15 geometry, engineered for deep cuts and high feed rates. This insert is optimized for continuous to lightly interrupted machining, utilizing its massive edge strength to maximize material removal rates (MRR) without sacrificing tool life.
The YBC251 grade provides a balanced matrix of tough carbide substrate and advanced CVD coating, offering a unique combination of high wear resistance and excellent resistance to plastic deformation, ensuring maximum productivity in your CNC turning operations.
Key Features
- [✓] Balanced Grade Performance: YBC251 balances tough substrate with advanced coating for optimal wear and impact resistance.
- [✓] Rugged Roughing Geometry: The -15 geometry handles massive depths of cut and high feeds with ease.
- [✓] Enhanced Thermal Stability: Advanced CVD coating manages high temperatures at the cutting edge.
- [✓] Maximum MRR: Achieve peak material removal rates for increased productivity.
Specifications & Parameters
The YBC251 grade is a CVD multi-layer coated carbide, designed specifically for stable turning in medium to roughing steel. The -15 chipbreaker geometry is designed for high feed rates (fn 0.25-0.7 mm/rev) and deep cuts (ap 1.5-6.0 mm), managing chip control through advanced chipformer features.
Applications
- Heavy turning in carbon steels (P15-P25) and alloy steels (P25-P35).
- Stable machining of cast irons (K10-K25), including gray iron and ductile iron.
- Suitable for large diameter components and forgings with significant material removal requirements.
- Performances excellently in stable to slightly interrupted roughing cuts on large lathes.
Compatibility
Fully compatible with all ISO standard tool holders designed for SNMG 1506 inserts. Designed for use on high-power CNC turning centers and large conventional lathes.
