Description

Particularly aggressive brush with bridle. Particularly suitable for deburring and work on surfaces on stationary machines.

Composite brushes from PFERD TOOLS have been specifically developed for industrial, automated use. They are suitable for a variety of applications and their variable clamping options mean that they can be used on many different drive systems. This offers the advantage that the workpiece can be produced and finished on the same machine. As a result, labour-intensive, manual work is reduced and reproducible results are achieved with short cycle times. For efficient use, numerous application parameters such as the processing time and feed rate must be coordinated with each other and a suitable brush must be selected.

Brushes with silicon carbide (SiC) are particularly well suited to deburring work and surface improvement. Rectangular filament [REC] is suited to applications that place particular demands on the aggressiveness of the brush. The larger cross-section of the filaments means that these are more stiff than round filaments and provide a greater contact area with the workpiece.

Plastic filament withstands temperatures up to 220 °C.

Advantages

Long tool life and aggressive brushing effect due to a very high filament density.
Extremely smooth operation due to even distribution of the filament material.
The bridle prevents the wires spreading out sideways.
If the filament has worn away down to the bridle, it can be removed from the bridle for further use. This does not affect the brushing behaviour.
The bridle enables the spreading out and flexibility of the brush filament to be controlled.
Abrasive grains are embedded in flexible plastic filaments, which means that the filament works on the sides as well as at the tip.
For aggressive work thanks to rectangular filament (REC).

Recommendations for use

Please observe the recommended rotational speeds.
Remove the bridle once the filament is worn down. Then the rest of the filament can be used.
Remove the bridle before starting work if you would like to achieve a large spreading diameter or access hard-to-reach areas.
Use coolant for applications where large amounts of heat are produced.
