Abrasives - For Precision Finishing Operations

Author: Administrator
About Abrasives NSN Parts and Its Product Range:

Abrasives in general are simply rough materials that are used to shape or finish work pieces, essentially like sandpaper. This product is extremely common for countless applications, ranging from industrial and domestic to technological applications. As a result, there are also many varieties of physical and chemical compositions of abrasives catered toward each application. Examples of common uses are for grinding, polishing, buffing, honing, cutting, drilling, sharpening, lapping, and sanding.

The basic concept behind abrasion is the difference in hardness or roughness between the abrasive itself and the material it is being used on, with the abrasive generally being the harder of the two materials. The idea is that two materials that rub against each other repeatedly will cause the less rough material to become more worn. This is applied in similar concepts depending on the application, with some factors to consider. The harder the abrasive, the harder and deeper it will cut into a substance. Grain size adhesion between grains, contact force, loading, and the use of lubricants and coolants also affect the speed and effectiveness of the abrasion. In addition, abrasives can be either classified as natural or synthetic. Abrasives made from natural minerals have been generally known to be more effective, although advancements in technologies is decreasing the gap between the two types. Nowadays, some synthetic abrasives are even considered to be similar if not more effective than natural abrasives. The following are common natural minerals that can be readily found and used to make abrasives: calcite, emery, diamond dust, novaculite, pumice, rouge, sand, corundum, garnet, sandstone, Tripoli, powered feldspar, and staurolite. On the other hand, these following minerals are either rare of hard to find, subsequently leading to the creation of synthetic materials to be used in their place: borazon, ceramic aluminum oxide, ceramic iron oxide, corundum, dry ice, glass power, steel abrasive, silicon carbide, zirconium alumina, boron carbide, and slogs.

Abrasive cartridge rolls are a very common and general-purpose product that is used for getting into hard to reach places. These are regularly used to port holes and edge breaking. They came in a wide variety of shapes and sizes, including regular, full tapered, and 747D end tapered. These abrasive cartridge rolls consist of aluminum oxide that composes the durable cloth. There are also a variety of power tool chucks and collects in which cartridge rolls can be placed securely on for easy use.

When choosing which type of abrasive to use for your specific application, the most important factor is the shape and size as well as the nature of the work piece that you need to finish. Some work pieces can use several different types of abrasives, although some will be more effective than others. For example, bonded abrasives can be used to sharpen knives, although the same knife can be more effectively sharpened with other flexible coated abrasives. It is also important to consider how some abrasives cannot abrade certain areas of work piece depending on its shape. If you choose an abrasive that is too rough, scratching may occur, which leads to diminished usefulness, trapped dirt or other material, erosion or penetration of coating, or increased friction.
