- disc grinding
Operation in which the workpiece is placed against the side of a wheel rather than the wheel’s periphery. See grinding.
Removal of undesirable materials from “loaded” grinding wheels using a single- or multi-point diamond or other tool. The process also exposes unused, sharp abrasive points. See loading; truing.
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.
Saint-Gobain Abrasives announced the introduction of its new Norton Stellar inserted-nut grinding wheels for double- and single-disc grinding that offer improved wheel life, increased parts per wheel and lower cost per part. The new grinding wheels are suitable for a wide range of industries including automotive, bearing, tool manufacturing, compressors, knife blades and job shop and general machining.
Norton Stellar grinding wheels have an over 30% longer wheel life than existing disc grinding products and require less dressing and parameter changes for increased productivity. The new wheels also have an improved material-removal rate of more than 15%.
