BRUSHES
Introduction & technical information
TECHNICAL
INFORMATION
Safe and operating speeds
The workplace safety regulations require the maximum safe speed to be observed. Details
can be found in the product overview in this catalogue, on the packaging and on the
brush itself (see fig.). The definition of operating speed is based on the peripheral
speed and brush diameter. The ideal operating speed is generally significantly lower
than the safe speed.
Operating and clamping width of the brush
The 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 length
The relationship between the diameter of the brush (brush body) and the length of the
trim determines how the brush operates. Generally speaking:
Soft, flexible brushes, e.g. for
finishing structured workpieces
or surface cleaning.
Trim length
Brush body Ø
More aggressive
brushing, e.g. for
deburring or removing
impurities.
Ideal position of brush in relation to workpiece
The contract pressure of a brush is defined by factors such as its insertion depth in the
workpiece.
Our recommendation is 3 times the filament diameter, e.g. 1.0 mm insertion depth for a wire
thickness of 0.35 mm.
The ideal position also ensures less wear. Our application engineers will be glad to advise.
Brush trim density
The 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 intricately
shaped surfaces.
