Material / Composition



	Your choices are...
	Superabrasive - CBN		Cubic boron nitride (CBN) is superabrasive grain with hardness second to diamond and a cubic crystal structure. CBN provides super grinding performance on carbon and alloy steel. Diamond is not useful in grinding steel or ferrous alloys because carbon and diamond readily dissolves or reacts with iron. CBN is produced synthetically in a high temperature, high-pressure process.
	Superabrasive - Diamond		Synthetic diamond is produced in a high temperature, high pressure process anvil press. Diamond is superabrasive grain with the highest known hardness and a cubic crystal structure. Diamond is used for grinding nonferrous metals, ceramics, glass, stone, and building materials. Diamond is not useful in grinding steel or ferrous alloys because carbon or diamond readily dissolves or reacts with iron. Diamond pastes are useful in ferrous polishing or lapping applications where heat and reactivity are not a factor. Diamond is susceptible to oxidation at higher temperatures
	Specialty / Other		Other specialty, proprietary or patented abrasive grain, grit or abrasive material.

Applications


	Applications:
	Your choices are...
	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.
	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 is 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 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.
	Polishing / Lapping		Finer abrasive grains are 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.
	Specialty / Other		Specialty, proprietary, patented or other unlisted blasting, finishing, grinding and abrasive application

Type / Shape


	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.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

	Conditioned / Rounded?		The shot or media are pre-conditioned or rounded to radius or round off any sharp edges or corners that would otherwise scratch or mar the parts. Cut wire shot is normally conditioned before use as peening media.

Size / Grading


	Grit Grade / Shot Size:		Applies to products using abrasive grains held in a matrix or bonded to a surface such as coated abrasives, MSL superabrasives, vitrified grinding wheels, dressing sticks, honing stones or grit dressers. Grit sizes are based on ANSI, FEPA, JIS, or proprietary grading system standards. Grading system standards define a grit size through specified upper and lower limits at certain points in the size distribution.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

	Grading System (Grit / Shot):
	Your choices are...
	ANSI - Bonded		American or U.S. grading or grit size standards for abrasive grains used in bonded abrasives or grinding wheels.
	ANSI - CAMI / Coated		U.S. grit size standards for abrasive grains used in coated abrasives, grinding belts or sanding discs.
	FEPA - F		European grading or grit size standards for abrasive grains used in bonded abrasives or grinding wheels.
	FEPA - P		European grit size standards for abrasive grains used in coated abrasives, grinding belts or sanding discs.
	JIS		Japanese grit size standards for abrasive grains.
	Mesh Graded		Grain or media graded to specific mesh sizes. Mesh size is determined by the number of wires per unit length. A higher mesh number indicates a smaller opening or fine particle. ASTM E-11 Standard (American Society for Testing Materials). This is the standard most widely used in North America. The opening is defined by a number (number 635 (20 µm) to number 3-1/2 (5.6 mm)) or is defined in inches (1/4 in. (6.3 mm) to 5 in. (125 mm)). ISO 3310-1 Standard (International Standards Organization). This is the standard used in Canada in the field of construction materials. The opening is defined in micrometers (20 µm to 37,500 µm).
	Micron Graded		Very fine abrasive grain graded to micron size ranges usually based an average particle size.
	Specialty / Other		Other unlisted, proprietary, or specialized grading or grit system.
