LNMU0303ZER-MJ

ZANHO LNMU 0303ZER-MJ is a high-efficiency double-sided 4-edge insert engineered for high-feed roughing. Optimized for Steel and Stainless Steel, it excels in small depth-of-cut ($ap=0.5$mm) machining by directing forces towards the spindle to minimize deflection. It delivers superior side-wall quality and maximum economy for mold making and 90° shoulder applications.

Key Technical Advantages

  • Double-Sided 4-Edge Economy: Features four highly effective cutting edges per insert, significantly increasing tool utilization and providing an exceptionally low cost-per-edge for mass production.
  • High-Feed Geometry (Max 0.5mm Ap): Specifically engineered for high-feed roughing at small axial depths, achieving massive metal removal rates (MRR) while maintaining process stability.
  • MJ Chipbreaker Optimization: Advanced rake geometry facilitates controlled chip curling and smooth evacuation, preventing thermal buildup and protecting the cutting edge in Steel and Stainless machining.
  • Reduced Tool Deflection: The large lead angle design directs cutting forces primarily towards the machine spindle, effectively suppressing vibration and deflection in long-overhang setups.
  • Superior Wall Quality: Delivers excellent surface integrity even during aggressive roughing, meeting the high verticality requirements of mold bases and 90-degree step components.
