This performance is credit to the composition of the grade that incorporates newly developed substrates, enhanced adhesion strength, a nano multi-layered AlTiN coating with a high Al content and Tungaloy’s exclusive PremiumTec special Surface technology.
The insert grade is at least 20% harder than alternative grades, a feature that prevents the development of micro-cracking and premature tool failure. With stable and extended tool life guaranteed, the bonding of the substrate prevents notch wear and further extends performance parameters when machining heat-resistant alloys. Under test conditions on a variety of Inconel, titanium and alternative aerospace grade alloys, Tungaloy AH8000 has more than quadrupled tool life whilst drastically reducing machining times. An extensive range of innovative geometries and chip breakers is available.
Within the AH8000 Series is the AH8005 grade for continuous machining at higher spindle speeds and the AH8015 grade that is extremely hard and durable, and intended for interrupted cutting applications.
As well as the two grade options, Tungaloy has developed its HRM chip breaker for finish to medium cutting, with the HRF breaker the premium choice for finish turning operations. The HRM chip breaker has rake face protrusions and an optimised rake face geometry that combine to reduce contact between the tool and workpiece, as well as generating low cutting forces and stabilising chip control. Adding to these negative insert chipbreakers, Tungaloy has now developed a positive insert line with new PSF, PSS and PS chip breakers.
The new line is available for a vast range of applications with an extremely diverse line of insert shapes and sizes available to suit most Tungaloy turning tool holders. The series includes a 35, 55 and 80° rhombic insert, a square, triangular and trigon insert (90, 60 and 80°), as well as a round insert range.
