Substance used for grinding, honing, lapping, superfinishing and polishing. Examples include garnet, emery, corundum, silicon carbide, cubic boron nitride and diamond in various grit sizes.
- 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.
Minimum and maximum amount a workpiece dimension is allowed to vary from a set standard and still be acceptable.
Saint-Gobain Abrasives, one of the world’s largest abrasives manufacturers, announced the introduction of its new Norton Winter AEON Electroplated Grinding Wheels for high precision applications in the automotive, medical and aerospace markets. An innovative design and manufacturing process give AEON wheels the ability to hold an extremely tight profile tolerance of ± 5µm at a maximum wheel diameter of ~24" (600mm) and width ~12" (300mm), weighing up to 551 lbs (250 kg).
Norton Winter AEON Grinding Wheels have a single usable abrasive layer design, with diamond or cBN particles mechanically fixed onto the core surface by an electrochemical process of nickel deposition. This unique layer design provides high grit retention levels for long wheel life. To save costs, the wheel core can be re-used. Once the abrasive grains are worn, the core of the wheel can be re-plated with new diamond or cBN grain in a continuous re-plating cycle.
"We are pleased to offer our customers with new high precision electroplated grinding wheels which are custom designed to meet their application requirements," said Andy Schoch, Product Manager for Single Layer Products, Norton | Saint-Gobain Abrasives. "New AEON Grinding Wheels provide up to a 50% increase in production efficiency, wheel life and number of re-platings."
