Type Of Coated Abrasives

Published on: 2024-01-29 13:40

A coated abrasive is manufactured by bonding abrasive grains to a versatile substrate using adhesives. The commonly used substrates include paper, cloth, fiber, and plastic films, and therefore, the grit sizes vary from very coarse (~2 mm) to ultrafine (sub-micrometer). Coated abrasives are often mentioned as "sandpaper", although they're not made with sand and most frequently aren't backed with paper.

Coated abrasives are formed by gluing natural and artificial abrasive grains. Abrasive grains include alumina, carbide, zirconia alumina, garnet and emery. Backing materials include paper, cloth, fiber and polyester film. Sanding rolls and sanding belts are ordinarily coated abrasives for hand use, usually for non-precision operation.

  1. CARTRIDGE ROLLS

Cartridge rolls are abrasive coated rolls that are suitable for sanding and finishing spaces that are difficult to access. The cartridge rolls are used on inside surfaces and inside corners where other abrasives can not hit high-speed grinders.

Cartridge rolls have an aluminum oxide-coated material that can provide a versatile method of hand sanding, especially in metalwork.

  1. ROSS PADS

Cross pads are used for small channel polishing, end deburring, and workpiece finishing. The Cross Pads provide greater flexibility and make it easier for users to see through the contact region.

These cross pads are perfect for fast grinding on channels, corners, or spotting on flat surfaces.

  1. DEBURRING WHEELS

Deburring wheels are used to wash, blend, deburr, finish, and polish metals and glass. For light to heavy precision mixing, deburring, and washing, these deburring wheels are ideal.

Deburring wheels provide uniform finishing to components and quickly and easily deburr the workpiece than hand finishing.

  1. FLAP DISCS

With a product that can grind and finish in one single action, flap discs offer precise angle grinding flexibility. Flap Disc is ideal for most ferrous & non-ferrous materials for sanding and finishing welds, deburring, rust reduction, and snagging.

  1. FLAP WHEELS

For most applications, from grinding to polishing, Flap Wheels are used. These flap wheels are usually used on ferrous alloy, high tensile materials, and a workpiece to finish complex shapes and tight contours.

The versatility of the wheel helps the wheels to navigate places that are hard to reach. On grinders, drills, impact wrenches, or handheld rotary tools, flap wheels connect.

  1. SANDING BELTS

Sanding Belts are used for deburring, grinding, blending, finishing, and polishing. These belts are backed with cloth, paper, or film.

  1. SURFACE CONDITIONING

Surface Conditioning Discs come in an all-inclusive range of grades and sizes and are an ideal first step for washing, mixing, deburring, and finishing.

    Film is a more recent development in the production of coated abrasives. Film media are made from a plastic sheet of uniform thickness. They fall somewhere between paper and cloth abrasives and are often considered the best of both worlds. Plastic is unlikely to tear and is light enough to be molded into precise shapes. Film backing is also waterproof and can be used for wet sanding applications. Film is well suited to automotive work that features many contours and requires fine polishing. Advantages Lasts longer than paper Tear resistant Flexible enough to match contours Waterproof Disadvantages More expensive than paper Usages Metal and automotive work Wet sanding Sanding complex contours and shapes...

    Paper-backed abrasives (i.e., traditional sandpaper) are the most affordable abrasives and are available in a wide range of weights, from light and flexible to thick and tough. Weight grades A to C are best suited to hand sanding and the use of pressure-sensitive adhesives (PSA) or hook-and-loop discs, while grades D to G are strong enough for stroke or wide-belt sanding belts. Paper substrates are the lightest and most widely used. However, paper is also the weakest backing used for coated abrasives. Paper's lack of strength is offset by its affordability. Paper backings are recommended for light to medium sanding jobs on surfaces such as wood, textiles, and lacquers, as they provide a good finish while generating less friction and heat. Paper is ideal for flat sanding applications and generally provides the best finish for flat sanding jobs. However, paper supports tear ...

    Cloth / fabric-backed abrasives are typically found on belts, although some sanding discs and sheets are available in cloth. They may be made from natural woven fibers (e.g., cotton) or synthetic fibers (nylon, polyester, rayon). Like paper, they come in different weights/thicknesses and varying degrees of flexibility and sturdiness. Your weight options are: JF- most flexible, making it a good choice when you’re sanding more detailed surfaces and profiles. J- made from a durable yet flexible cloth (e.g., denim) that can produce good results on both hand and machine sanding projects. X- stiff and sturdy cotton that is suitable for heavy machinery. YY- rugged polyester backing that’s strong enough to remove extra stock. Abrasives with a more lightweight and flexible cloth backing are recommended for finishing work while those made from heavier fabrics are designed fo...
