Ingersoll has introduced its Black-Rush series of cast iron ISO turning grades. CVD-coated grades TT7005 and TT7015 feature a stable substrate, strengthened coating layer and special post-coat treatment. The bond between the substrate and the coating layer increase chipping resistance, the company says.
The coating technology is designed to maximize hardness while providing thermal stability. Following the coating process, a special surface treatment is applied that is said to reduce friction, cutting force and build-up on the insert cutting edge.
TT7005 provides maximum wear resistance for both gray and ductile cast iron in high speed applications, while TT7015 is designed for quality all-around performance in these same materials with additional toughness for continuous to interrupted turning applications.
