Type names and their meaning

The type designation of our brushes indicates the following specific characteristics:

• Record: Brushes with crimped wire
• Multicord: Brushes with wire in a corded construction
• Ultra: Brushes with twist knotted wire
• Alpha: Brushes with ANDERLON abrasive bristles

What to do if the desired brushing effect is not obtained

Brushing effect too weak

• Increase the peripheral speed by increasing the brush diameter or the operating speed (observe the max. safety speed)
• Decrease the trim length
• Increase the diameter of the filling material

Brushing effect too powerful

• Reduce the peripheral speed by reducing the brush diameter or the operating speed
• Increase the trim height
• Decrease the diameter of the filling material

Surface finish too rough

• Reduce the peripheral speed by reducing the brush diameter or the operating speed
• Increase the trim height
• Decrease the diameter of the filling material

Surface finish too smooth

• Increase the peripheral speed by increasing the brush diameter or the operating speed
• Decrease the trim length
• Increase the diameter of the filling material

Determining the peripheral speed

The peripheral speed is a decisive criterion for optimum brush operation. The table below allows you to determine the relevant peripheral speed using the parameters rotational speed and brush diameter.

Please note: The rotational speeds specified in the catalogue are maximum admissible values which must not be exceeded under any circumstances. Generally speaking, the maximum speed does not need to be reached in order to achieve the best possible brushing effect. Depending on the brush type and the materials being processed, on principle we recommend certain circumferential speeds:

• Steel – appr. 30 m/sec
• NF metals – 18-20 m/sec
• Plastics – appr. 15 m/sec

• Steel – 35-40 m/sec

• Stahl - 18-20 m/sec
• NF metals – 18-20 m/sec
• Plastics – appr. 15 m/sec
