Abrasives

Abrasives are materials for jobs such as sanding ,grinding, polishing, lapping, honing, pressure blasting or other similar process. Abrasives come in different particle or grit sizes depending on how much material needs to be removed. Mostly used in decorating works for sanding timber, floor sanding and wood works.

Sand papers used for abrasives are generally characterised by high hardness, and moderate to high fracture toughness.

Old paint can be removed using sand paper. Each hard abrasive particle acts like a single point cutting tool.

Coarser grades/grits of abrasive ( comes in different sizes) are used where high volumes of material need to be removed, such as in coarse polishing, large scratch removal or operations requiring significant shape or dimensional change. Finer grades are mostly used after coarser grades to produce a higher quality surface finish than are possible with coarse grades.
