The HCN5110 (for titanium and its alloys) and HCN5115 (for super alloys such as Inconel and Hastelloy) feature the brand new M34 style chip breaker, which creates an extremely sharp cutting edge and facilitates the evacuation of swarf from the cutting zone. These features greatly reduce the cutting forces and the heat build-up during cut. And, with depth of cuts of up to 4.5mm they deliver excellent potential for volume metal removal.
Both insert types feature a TiAlN PVD coating which creates improved wear resistance due to the coating's friction reducing qualities and, in both cases, the carbide substrate delivers specific benefits when machining these materials. In the case of HCN5110 the carbide is in the ISO k10 range and creates a very hard and abrasion resistant substrate, whereas HCN5115 uses an ISO K15 grade of carbide to give high edge stability.
“The increasing use of these super alloys in more general purpose engineering, ranging from applications in the foodstuffs sector through to aerospace, will bring more and more subcontractors into contact with them,” said Tony Pennington, managing director, WNT (UK). “In developing these inserts, along with the technical on-site help that WNT can provide, we have taken the difficult out of these difficult to machine materials.”
HCN5110 and HCN5115 inserts are available in a variety of standard ISO insert shapes and sizes, including CNMG, DNMG, SNMG, TNMG VNMG and WNMG and, depending on the insert style and size, maximum depths of cuts of between 2mm and 4.5mm at feeds up to 0.45mm/rev.
