Use of computers to control machining and manufacturing processes.
- cubic boron nitride ( CBN)
cubic boron nitride ( CBN)
Crystal manufactured from boron nitride under high pressure and temperature. Used to cut hard-to-machine ferrous and nickel-base materials up to 70 HRC. Second hardest material after diamond. See superabrasive tools.
Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.

Stress present in a body that is free of external forces or thermal gradients.
Saint-Gobain Abrasives announced the introduction of its new Norton Winter Vitron⁷ CBN grinding wheels. The wheels feature a high-precision vitrified bond specifically designed for the high-performance external grinding of cam and crankshafts and internal grinding applications in automotive and bearing industries.
“Our Vitron⁷ wheels provide an ideal solution for the increasing demands of grinding in these applications where high surface quality, reduced cycle times and manufacturing costs are critical,” said Bill Lane, sr. product manager, Norton | Saint-Gobain.
Norton Winter Vitron⁷ wheels feature premium CBN grain particles uniformly dispersed throughout the bond matrix for maximum grinding efficiency. This enables manufacturers to achieve substantial increases in the number of finished parts between dress cycles, significantly reducing cycle times and extending wheel life up to 40 percent over existing products. Vitron⁷ wheels also grind cooler due to a lower specific grinding energy (SGE) that ensures minimal residual stress, for superior part quality with surface roughness degradation reductions of up to 30 percent.
When ID grinding, lower power results in less defection and minimizes taper while maximizing part straightness.
