Positive geometries join WNT’s HCN 2125 negative geometry insert range
1 min read
The original WNT HCN 2125 indexable carbide negative geometry insert series for stainless steel turning has now been expanded by the addition of positive geometries
The positive insert series comes in two geometries. For fine finishing WNT suggests the -PF23 for maximum surface quality and precision, with depths of cut between 0.2 and 3.4 mm and feedrates of 0.06 – 0.28 mm/rev. Where higher metal removal rates are required, the choice is the universal geometry -PF26 which generates low cutting forces and is capable of light interrupted cuts at depths of cut between 0.4 and 4.8 mm and feedrates of 0.06 – 0.35 mm.
WNT reports that when machining a component from 1.4301 (X5CrNi18-10) / AISI 304 stainless steel using combined longitudinal and face turning, HCN 2125 inserts with the positive –PF23 geometry achieved cutting data of Vc = 150 m/min and had twice the life of the product it was tested against.
HCN 2125's carbide substrate and Dragonskin PVD tool coating offers wear resistance at elevated cutting data when used for machining stainless steel, Austenitic, ferritic, Martensitic or duplex materials.
