Generalities A brush is rather special artefact. Overall, it has a well-defined geometric shape and precise dimensions, but locally, the working surface is formed by thousands or millions of small circles, which are the ends of the filaments from which the brush is made. This characteristic makes the brush different from any other mechanical element used in the technique. In fact, the working surface of a brush can be rigid or soft, oriented or isotropic, locally variable, and above all has great adaptability to the irregularities of the workpiece. Each filament behaves individually even though it is collectively part of a single working surface. The filaments are therefore the basic building blocks of the brush. They can be of three types: Synthetics Naturals Metallic
