Abrasive wheel

Sandblasting[ edit ] Sandblasting or bead blasting is a generic term for the process of smoothing, shaping and cleaning a hard surface by forcing solid particles across that surface at high speeds; the effect is similar to that of using sandpaperbut provides a more even finish with no problems at corners or crannies. Sandblasting can occur naturally, usually as a result of particles blown by wind causing aeolian erosionor artificially, using compressed air. An artificial sandblasting process was patented by Benjamin Chew Tilghman on 18 October Sandblasting equipment typically consists of a chamber in which sand and air are mixed.

GLOSSARY In developing this glossary, it became apparent that many terms are simply names for tools and methods which have evolved over time and from a scientific perspective are very similar. The result is a lack of clear distinction between processes such as honing, lapping, grinding,and superfinishing.

As new methods and products evolve, unfortunately, the distinction becomes even less clear.

For industrial application, however, abrasives are minerals from a select group of very hard minerals used to shape, finish, or polish other materials.

In processes that grind, finish, polish, lap, or hone, abrasives are typically limited to synthetic minerals with the exception to diamond and garnet. Common abrasive minerals appear in a various crystalline forms of aluminum oxidesilicon carbidezirconium oxidediamond and cubic boron nitride.

Abrasive wheel used in polishing or blast cleaning, an abrasive can be any substance used to remove material including ice, solid carbon dioxide, walnut shells, plastic, sand or aluminum oxide. Abrasives such as aluminum oxide, silicon carbide and zirconia are typically called conventionl abrasives due to their long history of use.

Abrasive Belt A closed loop of coated abrasives used on tools that range from small handheld equipment to very large machines that use belts five feet wide. Made by joining a strip of coated abrasive. Abrasive Blast Cleaning A process that uses a high-pressure stream of air of water to propel abrasive particles at the surface of a workpiece.

Purposes vary from cleaning to removal of coating or surface contaminates to preparation for painting or some other surface treatment. Abrasives range from silica or sand to garnet or aluminum oxide abrasives depending upon applications. Density, relative hardness, cost, and friablilty are important characteristics that determine the usefulness of a particular abrasive.

Some recycled materials such a glass beads are made from recyled glass have special applications. Other material such as dry ice solid carbon dioxide are used because they level no residue of the finished part.

Precision from abrasive blasting can range from process used to remove stencil lettering on semi conductor components to removing rust and paint from ships or bridge structures. Abrasive Cut Off Saw A thin resin bonded, reinforced grinding wheel used to saw or cut off metal from bar stock.

Abrasive Grains The individual grits of abrasive mineral, also called grit, or abrasive mineral.

Alumina Another term for aluminum oxide Aluminum Oxide The most common industrial mineral in use today. A synthetic form of the natural mineral mineral corundum. Although natural corundum was important historically, modern industrial abrasives use aluminum oxide produced synthetically by refining bauxite ore in a variety processes.

In one process crude aluminum oxide is made by melting bauxite to form a fused aluminum oxide, which is later crushed and sized. The various types of fused aluminum oxides are distinguished by levels of chemical impurites remaining in the fused mineral Titanium and Chromium oxides are typical.

Other techniques to make industrial abrasive start with treating bauxite ore with a sol gel process to create alumina that is sintered to produce with an extremely fine crystalline structure typical of the sol gel products available by Saint Gobain Abrasives. The many variations in products and related tradenames arise from variations in the manufacture and processing of bauxite ore and crude fused or sintered minerals.

6" - 10" Diameters. Wheel brushes are excellent for light deburring, edge blending and general surface finishing.

Abrasive nylon wheel brushes are safe, non-reactive and offer an excellent alternative to traditional steel filament brushes for extrusion cut-off burrs and mount on most pedestal grinders. 1" - 4" Diameters Abrasive nylon is excellent for light deburring, edge blending and general surface finishing.

Copper Center wheel brushes may be gang mounted and come if a variety of arbor hole sizes. CALCULATING SFPM The performance of grinding wheels and quality of the finished workpiece is affected by how fast the abrasive grains sweep over the workpiece.

That speed affects surface quality, workpiece burn, material removal rates, and other factors. Since the speed of the abrasives on the wheel perimeter depends upon the diameter of the wheel, RPM isn't a useful measure.
