MillQuadFeed – Shroud Ring – U type insert
IMPROVED TOOL LIFE & PRODUCTIVITY
The challenge of short tool life in machining heat-resistant superalloys was addressed by implementing U-type geometry combined with the AH8015 grade.
This optimization of the small KAPR, along with the grade's thermal resistance, resulted in a 3.3 times increase in tool life.
In addition, productivity increased by 1.4 times due to the increased number of teeth.
