POWER BRUSHES Wire Brush Selection Società Mechanical Compatibility Italiana Relation between the hardness of the tool and the surface to be treated. It’s not recommended to use hard carbon steel for light deburring of a soft metal like aluminum. An alternative recommendation is to use synthetic filaments. Tecnospazzole Between the brush (filament) and the surface there must be: Chemical Compatibility The wire must withstand the corrosive attacks from the chemical environment. It’s not recommended to use carbon steel brushes in the presence of acid solutions and high salt environments and the...

Be aware that the Outer Diameter of end brushes and cup brushes increase significantly when they rotate. For related information, see Power, Speed and Pressure paragraph on page 62. Select SIT wire brushes with diameters ranging from 1mm - 0.04" to 1000mm - 40". The products in our catalog provide recommended MAX RPMs. | | MADE IN ITALY | TANISBRUSH.COM 59

POWER BRUSHES Choosing the Wire Diameter Società Italiana This is why you should always try to use the thinnest filament possible compatibly with the desired finishing. Tecnospazzole Wire size greatly influences surface brushing aggressiveness and the obtainable finishing. Thin filaments are more flexible and have higher fatigue resistance but they are less aggressive. A bigger diameter gives higher aggressiveness but is also susceptibility to breakage. SIT offers filling materials with diameter from 0.10mm - 0.004" to 2.5mm - 0.1" and a product range that covers almost all of the possible brushing...

Choosing the Fill Density Wire density affects the “hardness” of the brush surface: the thicker the wire, the harder the surface since there is a greater number of individual working tips (for a set area). High density brushes are characterized by lower penetration into the surface and smaller opening during processing. Wire density also affects the service life; distributing the brushing action among multiple tips of wire makes each filament less deformable. On the other hand, high density brushes accumulate greater frictional heat, therefore increasing the risk of overheating the brushed surface....

POWER BRUSHES Power, Speed and Pressure Società Italiana Tecnospazzole Brush selection criteria considered until this point have to be evaluated together with the characteristics (power, speed and pressure) of the source of power since these have a strong influence on the surface finishing. For example, a higher pressure will increase the face width of the brush obtaining a smoother surface finish. Brush characteristics together with operating parameters will determine the output of the surface treatment job. The surface finish has to be evaluated in terms of operational quality and efficiency:...
