Emery; It is an abrasive used in sanding process for smoothing rough surfaces. In other words, it is cutting.
Abrasive Materials and Places of Use The quality of the sanding process depends on the hardness and structure of the sandpaper. The hardness of the sandpaper or stone is evaluated by the binding strength of the particles. The property of the adhesive or binder material directly affects the particle's ability to function without breaking. The particles in the grinding wheel used for a while are blunt. If working with a sanding paper or sandpaper that is suitable for the sanded material, the friction and pressure effect between the sanded material and the grain breaks or breaks the particle. If the grain is broken, new edges with sharp edges will continue to grind the sanded tool.
