BRUSHES Hand brushes

BRUSHESIntroduction & technical informationTECHNICALINFORMATIONSafe and operating speedsThe workplace safety regulations require the maximum safe speed to be observed. Detailscan be found in the product overview in this catalogue, on the packaging and on thebrush itself (see fig.). The definition of operating speed is based on the peripheralspeed and brush diameter. The ideal operating speed is generally significantly lowerthan the safe speed.Operating and clamping width of the brushThe operating width describes the contact surface between brush and workpiece.Press the trim together slightly to measure the operating width.The clamping width is measured between the washers (see fig. left).Contact us for more information on the clamping width.Brush diameter and trim lengthThe relationship between the diameter of the brush (brush body) and the length of thetrim determines how the brush operates. Generally speaking:Soft, flexible brushes, e.g. forfinishing structured workpiecesor surface cleaning.Trim lengthBrush body ØMore aggressivebrushing, e.g. fordeburring or removingimpurities.Ideal position of brush in relation to workpieceThe contact pressure of a brush is defined by factors such as its insertion depth in theworkpiece.Our recommendation is 3 times the filament diameter, e.g. 1.0 mm insertion depth for awire thickness of 0.35 mm.The ideal position also ensures less wear. Our application engineers will be glad toadvise.Brush trim densityThe trim density is determined by the number of wire tips per surface unit.High trim densities are best for cutting performance and service life (e.g. deburring).Lower trim densities increase brush flexibility and are required for finishing intricatelyshaped surfaces.Any questions?
