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.
- aluminum oxide
Aluminum oxide, also known as corundum, is used in grinding wheels. The chemical formula is Al2O3. Aluminum oxide is the base for ceramics, which are used in cutting tools for high-speed machining with light chip removal. Aluminum oxide is widely used as coating material applied to carbide substrates by chemical vapor deposition. Coated carbide inserts with Al2O3 layers withstand high cutting speeds, as well as abrasive and crater wear.
Phenomenon leading to fracture under repeated or fluctuating stresses having a maximum value less than the tensile strength of the material. Fatigue fractures are progressive, beginning as minute cracks that grow under the action of the fluctuating stress.
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.

inner diameter ( ID)
Dimension that defines the inside diameter of a cavity or hole. See OD, outer diameter.
Weiler Abrasives, a leading provider of abrasives, power brushes and maintenance products for surface conditioning, has expanded its popular Tiger brand of abrasives to include cups, cones and plugs for metal fabrication, including fab shop, tool sharpening, pipeline, rail frog construction and shipyard applications. Tiger AO cups, cones and plugs are designed to deliver the right combination of performance and value. The aluminum oxide grains, along with a strong bond, provide a long product life and a consistent cut rate for grinding metal.
“We carefully formulated our Tiger AO cups, cones and plugs to provide consistency and reliability,” says Tony Hufford, category manager — metal fabrication, Weiler Abrasives. “The abrasives are specifically designed to be ready to use out of the box without a break-in period, allowing users to get right to work and get instant results.”
The Type 11 cup wheels for grinders are precision balanced to ensure smooth, vibration-free operation and reduce operator fatigue, while wearing at the appropriate level to maximize grind rates. An innovative safety nut locks in place to increase safety and prevent separation. Zinc-plating prevents oxidation, which eliminates contamination, and keeps threads clean for easy mounting and removal. The cup wheels are available in 4-, 5- and 6-inch diameters and are ideal for heavy metal removal, grinding, rough beveling and removing cracks or flaws.
Designed for ID cleaning, hole-edge beveling, smoothing weld seams, bevel grinding, transitioning and grinding in hard-to-reach areas, the Tiger AO cones and plugs for die grinders feature an open-face design that provides an aggressive cut rate right out of the box. Like the Type 11 cup wheels, the cones and plugs are precision balanced for smooth, easy use. Tiger AO cones and plugs also feature an anchored hexagon nut that secures the abrasive to the tool to increase safety and prevent product breakage. These cones and plugs are available in the most common types, 16, 17, 18 and 18R, and sizes ranging from 1 to 3 inches in diameter.
All three product categories are best for use on soft and hard carbon steel, stainless steel, cast iron and ductile iron.
