Abrasive tools-material type and industrial application

Abrasive tools are typically made of hard metal for a variety of manufacturing and household uses, for woodworking and metalworking to form or complete a piece of work. Abrasive tools are usually ground or machined to remove wood or minerals. It has a sleek, elegant or finished look, or slowly strips a piece of material until the desired shape is achieved.

Abrasive tools type
Abrasives are divided into two main parts: natural abrasives and synthetic abrasives. Synthetic abrasives are designed to simulate organic materials and are manufactured rather than excavated. Both abrasives are used in a variety of forms and are most often coated or bonded. Abrasives are designed to include rolls, belts, rods, plates, blocks, free particles, sponges and sheets.

Bonded abrasive tools

Bonded abrasives are abrasive tools that are made into grinding wheels, cutting wheels, sectors, cones and other similar forms or “bonding” types for use in many aspects of woodworking and metal finishing or cutting applications. Bonded abrasive tools are typically used with drill bits or rotating tools. The idea of ​​bonding natural or synthetic abrasive tools together is to bond the pellets together to provide a hard material for cutting or grinding purposes.

Coated abrasive tools

Coated abrasives are metals that can also be used to bond abrasive grinding wheels suppliers. Free and closed coatings are two types of abrasive tools layers. In open coated abrasive tools, 50% or 75% of the cover layer is coated with abrasive particles. These grains contain materials such as corundum, garnet, silicon carbide, light brown alumina, heat-treated alumina, zirconia alumina and ceramic alumina.

Support type

The variety of abrasive tools backings is paper, fabric, film or fiber. The coated abrasive tools structure consists of a backing, adhesive and metal. Minerals or grains typically adhere to the backing and most commonly include a base coat and a sizing coat. The base coat is applied to the backing, then metal or granules are used, plus the sizing layer of the adhesive.

Paper lining

The paper backing is available in 6 weights or widths: A, B, C, D, E and F. A and B loads are lightweight paper for light to medium grade cereals. These are commonly used for manual sanding and hand-held electric sanders. B is thicker and more valuable than A heavy paper.

The C and D weight paper backings are average weight thickness and are used primarily for medium grade cereals, typically used in thin sheets, discs and light sanding areas. E and F weight papers are stronger and more durable, helping to polish heavier grains. E and F are mainly used to produce sandpaper and use the shape of document board, belt and disc. The F density is also used for drums and cones.


The cloth backing includes cotton, rayon and polyester. The density and stiffness of the backing are indicated by weights J, X, Y, M, S, T and Z. J’s weight is the thinnest and most elastic of the cotton backing. X weight is the average and can handle the widest range of applications, such as tools. Y weights are used for complex drill bits intended for heavy duty applications. M weight is one of the more robust cotton backings for more advanced heavy duty applications. The A and T weights are used in extra wide belts and have the best strength in both weaving directions, while the T weights are practiced in high horsepower machines.

Rayon is durable, elastic, and resistant to tearing and abrasion at the ends. Polyester is a very strong and tough backing for use in applications requiring extra strength and tarpaulin backing. The grain backing is both hard and strong, but flexible enough to be worn with a roller and disc made of rag. Polyester film is another adjustable primer that can be used for very light to medium particle size disc rolls and areas. Film products are often used in combination with aqueous solvents because the backing is completely waterproof.

Industrial application of abrasive tools

The industry uses abrasive tools in three basic models. They can be combined with metal to form a solid machine, such as a grinding wheel, cylinder, belt, cup, fan or rod. They can be added to paper, cloth, plastic or other materials just like sandpaper. Alternatively, they can be practiced in a loose form, such as when sanding a building surface with sand splashing during sand blasting.

Most industrial uses of abrasive tools fall into one of four categories. Cleaning involves extracting dirt and stains from the surface of the object. Part of this is the use of a grinding wheel to polish the outer surface of the metal. Forming is a method of using abrasive tools to produce the desired shape. Grinding tools are examples of forming. Sizing is a polishing process in which the abrasive tools gradually disappears until the exact shape is found. Cutting is the division of material into two separate parts.
