MillQuadFeed – Turbine Blade – U type inserts
IMPROVED TOOL LIFE
The competitor’s inserts suffered from frequent edge chipping and fractures, requiring indexing after machining each part. In contrast,
MillQuadFeed-U type, with its ideal insert geometry and small entrance angle, achieved double the tool life compared to the competitor in exotic material machining.
Even after machining two parts, no edge chipping or fractures occurred, significantly enhancing process security.
