Insert range boosts super alloy turning

The latest insert grade from WNT (UK) will make big improvements in the machining of heat-resistant super alloys, through increased productivity and tool life.

HCN5115, part of WNT's Mastertool Dragonskin range, has been developed to address the problems encountered when machining heat-resistant super alloys (HRSAs), namely heat generation at the cutting edge.

This has been achieved through the creation of a grade that has high heat and wear resistance.

These properties have been arrived at through grade and geometry developments, the latter designated -M34 by WNT (UK).

The result is increased cutting data, and tool life of over 85 per cent in some applications.

In one example, cutting speed was increased from 35m per minute to 65m per minute, and depth of cut increased from 0.8mm to 1.5mm.

Tool life increased from 12 components to 30 components.

Currently, HCN5115 inserts are only available in negative geometries (CNMG, DNMG, SNMG, TNMG, VNMG and WNMG), but the range will expand in the coming months.
