| Applications: | |||
| Your choices are... | |||
| Abrasive Jet Cutting | Abrasive water jets cut sheet materials or to remove materials from a surface by generating a focused stream of fluid mixed with abrasive particles. Garnet grain is widely applied as the abrasive media in abrasive water jet cutting. Air abrasive jet cutters are employed in cutting softer materials or microcutting applications. Precision air abrasive blasters or micro-jets produce extremely fine and precise streams. They are used for drilling, detailing, and precision cutting of printed circuit boards and other high quality components. The abrasive grains most commonly used in most air systems are aluminum oxide or silicon carbide. | ||
| Blasting | Abrasives and media for abrasive blast machines and sandblasters. Abrasive blast machines and sandblasters clean and prepare surfaces by directing a stream of abrasive particles against a part or a surface. Blast wheels, pressurized water, or compressed air drive the abrasive or blasting media. Blasting is used for finishing, surface texturing, roughening, frosting / etching, degreasing, deburring, deflashing, descaling, stripping of coatings, and surface preparation of products made of metal, wood, plastic, glass, or other materials. Aluminum oxide, coal slag, glass, plastic media, corncob, and nutshell are commonly used in blasting applications. | ||
| Blending & Intermediate Cutting | Abrasive products are designed for blending or removing parting lines, seams, or other significant surface imperfections. Medium or medium fine grit products are typically used for light cutting or intermediate material removal applications. | ||
| Cleaning / Surface Prep | Cleaning and surface preparation products are finishing media that are formulated for cleaning, degreasing, de-oiling, descaling, texturing, roughening, discoloration removal, and other surface preparation applications. | ||
| Coated Abrasives | Coated abrasives contain abrasive grains held together in a matrix of resin, rubber, or other binders. They are used to remove surface materials such as metal, ceramics, glass, plastics, and paint. Coated abrasives are used in both grinding wheels and abrasive stones or sticks. Coated abrasives use several different types of abrasive grains. Aluminum oxide, the most common industrial mineral in use today, is used either individually or with other materials to form ceramic grains. Aluminum oxide is also combined with emery and crocus to produce abrasives suitable for finishing applications. Other types of abrasive grains include garnet, tungsten carbine, silicon carbide, and alumina-zirconia. Super-abrasive diamond pastes are useful in ferrous polishing or lapping applications where heat and reactivity are not a factor. Cubic boron nitride (CBN), a superabrasive grain with hardness second to diamond and a cubic crystal structure, provides superior grinding performance on carbon and alloy steel. | ||
| Deburring / Deflashing | Abrasive products designed or suitable for removing burrs, sharp corners, part lines and flash (deflashing). | ||
| Descaling / Stripping | Abrasive grit or media designed or suitable for decsaling or coating stripping applications. http://205.153.241.230/P2_Opportunity_Handbook/section5.html | ||
| Fast Cutting / Aggressive | Fast cutting abrasives are coarse grit products typically designed for heavy cutting or material removal applications. | ||
| Grinding / Ball Milling | Media designed for ball milling or grinding down of bulk, powder or granular materials into finer powder forms. Typically ceramic bead, hard metal shot, carbide balls or other ball shaped media are used. The hardness of the powder or bulk material being ground will determine the selection of the media's material. Ball milling processes can disperse or mix pigments or fillers into resins, paints, coatings, plastics, rubber or adhesives. Media grinding or ball milling is also used to mechanically alloy metal powders allowing the creation of alloys that cannot be formed through fusion processes. | ||
| Grinding Wheels / Bonded Abrasives | Bonded abrasives contain abrasive grains held together in a matrix of glass, resin, rubber, or other binders. They are used to remove surface materials such as metal, ceramics, glass, plastics, and paint. Bonded abrasives are used in both grinding wheels and abrasive stones or sticks. Grinding wheels are used in a variety of applications and industries, while abrasive stones or sticks are used for sharpening edges and honing internal or external surfaces Grinding wheels are used for metal removal, dimensioning, and finishing. They consist of an integral shank, pin, shaft, or mandrel that drives a mounted wheel or blades. There are many types of grinding wheels, some of which are numbered by the American National Standards Institute (ANSI). Straight wheels are simple, flat discs without any recesses, flaring, or cups. Type 5 wheels are recessed on one side. Type 7 wheels are recessed on both sides. Both flaring-cup and straight-cup wheels are commonly available. Tapered grinding wheels have a thicker cross-section at the bore. Cylindrical wheels feature a length that is equal to or greater than the thickness of the wheel. Depressed center wheels exclude the mounting hardware from the grinding process. Dish wheels often contain superabrasives. | ||
| Peening | Peening shot and beads consists of small metal balls or glass beads. Peening shot is used impart compressive stresses into the surface of part as well as deburr sharp edges without removing material. Induced compressive stress improves fatigue strength. | ||
| Polishing / Lapping | Finer abrasive grains designed or suitable for precision surfacing applications such as polishing, honing, lapping, color buffing, brightening or other high surface smoothness finishing applications. The fine abrasive grit is incorporated in finishing compounds, coated abrasive lapping films, superfinishing bonded abrasive products and/or polishing compounds. Polishing compounds, pastes or creams contain very fine abrasives as well as waxes or oils. Polishing compounds produce highly lustrous, bright and buffed surfaces. Specialized non-abrasive chemical agents are also available for electropolishing or chemical polishing processes. Color buffing produces a bright lustrous or polished surface. | ||
| Tumbling / Mass Finishing | Tumbling and mass finishing media is used to deburr, burnish, color, descale, polish or clean parts and components during finishing processes. Tumbling and mass finishing media involve choosing finishing shapes and media for particular tasks. Finishing shapes include balls, cones, ballcones, wedges, pins, tapers, cylinders, cut wire, diagonals, angle cuts, diamonds, cubes, oval balls, eclipses or balls with flats, crushed grit, pyramids, triangles, and stars or tristars. Finishing media consists of metal, ceramic, plastic, natural, wood, nutshell, corncob, carbonate, mineral, and synthetic materials. | ||

| Shape | |||
| Your choices are... | |||
| Abrasive Grain / Grit | Abrasive grain or grit consists of smaller, sharp particles of hard materials, minerals, ceramics, carbides, or fused oxides. Most abrasive grains or grits have crushed irregular shapes, but a few abrasive grains are available with regular rod or platelet shapes such as precipitated alumina or extruded sol-gel abrasives. Abrasive grains are typically sized or graded using a series of mesh sieves with specific percentage ranges for each screen depending on grit size. | ||
| Crushed / Irregular | Abrasive grit, nugget or media has a crushed or irregular shape. Typically, the irregular or crushed shapes are very angular with sharp edges for abrading, cutting or grinding. Aluminum oxide, silicon carbide, nutshell, glass and mineral abrasives or grit typically have a crushed shape. Abrasive grit or media has a blocky or rounded crushed shape, which is useful for blasting and grinding wheel applications. Abrasive grit or media has a sharp or angular crushed shape, which is useful for coated abrasive or single layer metal bond abrasive applications. | ||
| Pebbles / Balls (Spherical / Rounded) | Media is a spherical pebble, bead, ball, or rounded shape. | ||
| Finishing Media / Nuggets | Finishing and shaped media includes coarse, regular shapes for mass finishing, tumbling, blasting, and ball grinding applications. Finishing media types or shapes include steel shot, cut wire, triangles, pyramids, cones | ||

| Bulk Density: | Bulk density is the mass per unit area for a material taking into account internal porosity. The bulk density is dependent on the theoretical density of 100% dense body and the actual level of porosity between abrasive or media particles. Tap density and loose pack density are two types of bulk density used to understand particle shape, interparticle friction and flowability. Loose packed density (LPD) or aerated density is the density of the powder or particulate body without any settlement, mechanical agitation, vibration, or tapping. Usually, loose packed density measurements are made by determining the mass of powder in a sample container of known volume. Tap or packed density is the density of the powder or particulate body after settlement from tapping, mechanical agitation, vibration, or light packing (not compaction or consolidation). Often, both loose packed and tap density measurements are made to determine the Hausner ratio, which is calculated by dividing the loose-packed density by the tap density. Carr index is also related to loose packed and tap densities. The Carr index and Hausner ratio provide an indication of flowability. | ||
