CVD grade for cast iron turning
- Published: May 25, 2017
Tungaloy Corp. is further expanding its T515 range, a CVD grade with what it describes as unmatched performance in cast iron turning.
The added line ups of regular-sized inserts are available in T515 with CM chipbreakers for medium turning of cast iron. An entirely new insert line of T515 is also being added to the ISOEco-Turn series.
T515 is a versatile CVD grade perfectly engineered for efficient cast iron turning, smartly combined with a dedicated coating layer and cemented carbide substrate. With enhanced adhesion between the coating and substrate, T515 delivers exceptional persistence to chipping and flaking, thus offering added stability in high speed cast iron turning.
The added thickness of an alumina (Al2O3) coating layer (1.7 times thicker than conventional grades) enhances resistance to wear during extremely abrasive, high-speed cast iron machining, extending tool life for fewer tool changes. PremiumTec, Tungaloy’s original surface treatment technology, improves the surface smoothness of the coating for outstanding resistance to chipping and built-up edge.
ISOEco-Turn will include two new T515 insert ranges: 16 types in a general-purpose range with no chipbreaker, and 6 types in a sharp-edged, free-cutting insert line with CM chipbreakers.
