Material & Coating Technology
The insert features the GC 1125 grade, a PVD TiAlN (Titanium Aluminum Nitride) coated超细晶粒硬质合金 (ultra-fine grain carbide) that represents a breakthrough in cutting tool material science. This composition delivers:
-
Superior Wear Resistance: The multi-layer TiAlN coating provides exceptional resistance to abrasive wear, extending tool life by up to 50% compared to conventional coatings in stainless steel applications.
-
Enhanced Toughness: The ultra-fine grain carbide substrate ensures high刃口韧性 (edge toughness), making it suitable for light interrupted machining common in automotive and aerospace components.
-
Heat Resistance: The coating's thermal barrier properties maintain cutting performance at medium to high speeds (up to 475 m/min for non-ferrous materials), preventing thermal cracking in heat-sensitive alloys.
MF Chip Breaker Design
The MF (Medium Finish) chip breaker geometry is specifically optimized for finishing operations with low to medium feeds. Key features include:
3D rake angle design reduces cutting forces by 15-20%, minimizing workpiece deformation while ensuring sharp cutting action. The double projection structure enhances chip fragmentation, even for tough-to-machine materials like 304 stainless steel.
This design excels in producing consistent, manageable chips across a range of materials, reducing machine downtime for chip removal and improving process stability.
