The using speed of a brush can be:

• brushing of steel: 20 up to 25 m/sec.
• brushing of non-ferrous: 15 up to 20 m/sec.
• brushing of synthetical materials: 10 up to 15 m/sec.

These are indicatives and valid using speeds for a wire of Ø 0,30 mm.

Other parameters can influence the choice of a brush: the diameter of the wirelength of the wire (L)the nature of the wire the rotation speed. The best results are obtained by applying lightly, just enough to maintain the tip of the wires in contact with the worked piece.

Avoid pressing too hard. If a high pressure on the brush is necessary to obtain an effective brushin, choose a harder brush (thicker wire) or increause the rotation speed.

Brushes with a Ø 0,1 mm wire must operate at a lower speed.
