Historically, the principal method of construction of superabrasive monolayer tools was, up until the early 1970's, entrapment electroplating with nickel on a steel or otherwise suitable metallic form. In 1975, a patent was issued to J. T. Lowder et al. for a process of brazing diamond to create mono-layer tools with a nickel-chromium-boron alloy.
Grinding is regarded as a special multiple edge cutting process, in which the abrasive grains remove the workpiece material at the microlevel. The grain–workpiece interaction, which resembles the microcutting process, directly modifies the workpiece surface and dominates all the output measures of grinding process. Recently, a virtual single-layer cubic boron nitride (CBN) grinding wheel ...

Cubic boron nitride (CBN) is a superabrasive traditionally used to grind steels and nickel alloys. Though not as hard as diamond (4,500kg/mm 2 vs. 9,000 kg/mm 2), CBN is not chemically reactive with ferrite-based and nickel alloys, allowing it to outperform diamond-based grinding wheels in life and material removal rates on these materials 1.A 1987 study by Hitchiner and Wilks showed that …
The paper addresses thermoelectric phenomena that occur in superabrasive grinding. It has been found out that the machining of hardmetals using diamond wheels is characterized by a negative value of tribo-thermal EMF, while in the case of cBN grinding of high-speed steels the value is usually positive. As the tribo-thermal EMF in cBN grinding grows the wheel wear decreases, while in diamond ...
Therefore, care must be taken when adjusting these parameters to not introduce other problems into the process. 2) Grinding Wheel Dressing. The dressing conditions for both conventional and superabrasive grinding wheels can be manipulated to help improve surface finish. This is.
