Formation mechanism of alumina layer in protecting cubic ...

However, Gastel et al. claimed that the machinability difference comes from the manganese sulfide (MnS) inclusions to form a protective layer on the cubic boron nitride (cBN) tool surface when turning FGI at high cutting speed (over 400 m/min). The presence of MnS layer, which works not only as a barrier against diffusion and oxidation but also as a lubricant to reduce friction between cutting tool and FGI, was identified as the primary reason for the excellent machinability of FGI at high ...

Taking The Fear Out Of Hard Turning : Modern Machine Shop

The "secret" to successful hard turning is high surface speed. Applications typically involve tripling or quadrupling the surface speed used for carbide inserts when CBN inserts are substituted. CBN (also called PCBN, polycrystalline cubic boron nitride) is a man-made material second only to diamond in hardness.

Parts that are induction-hardened may require a finish machining pass because the quality of the finished surface was altered. For these hardened parts, the shop is more likely to use cubic boron nitride (CBN) inserts that are typically used for most hard turning applications.

The turning trials were performed on a MHP MT-80 CNC turning centre having a variable spindle speed of 3000 rpm rated at 30 kW. The workpiece material was a bar (108 mm diameter × 375 mm length) of Inconel 718 nickel based superalloy in the solution treated and aged condition with a bulk hardness of ∼44 HRC.
