Brush Selection Criteria
The criteria for choosing the most suitable brush for each application are the following:
- The work to be carried out.
- The type of surface which is to be brushed.
- The machine with which the work will be done and its speed
To choose the type of material, wire or abrasive nylon:
- The material of the surface to be brushed.
- The type of finish desired
- The machine with which the work will be done and its speed
Furthermore, other characteristics must be taken into account:
- Brushing is more efficient at greater brush diameters. (Do not exceed 175 mm. in diameter in portable machines of 6000 r.p.m. maximum.)
- Shorter trim lengths result in more aggressive brushing and longer trim lengths offer better flexibility for irregular surfaces.
Problema | Soluciones recomendadas |
---|---|
The brushing is excessively aggressive | Choose a brush with finer wire. Choose a brush with longer trim length. Work at a lower speed. |
The brushing is not sufficiently aggressive | Choose a brush with thicker wire Choose a brush with shorter trim length. Work at a higher speed. |
The brush does not remove the burr, but flattens and polishes it | Chose a brush with thicker wire. Choose a brush with shorter trim length. Work at a higher speed. |
The finish needs to be finer | Choose a brush with finer wire. Choose a brush with a longer trim length. Choose a nylon abrasive brush |
The finish needs to be coarser | Choose a brush with thicker wire. Choose a brush with shorter trim length. |
The brushing is not uniform | Reduce the brushing pressure. Automate the operations to avoid human variability. |
The wires break | Reduce the brushing pressure. Choose a brush with finer wire. Work at a lower speed. |
The brush has a very short useful life | Choose a brush with finer wire. Choose a brush with greater width. Reduce the brushing pressure. |
Brushes identification by colours
To help to identify the type of wire of our brushes, we identify the steel wire brushes with red colour plates; and the stainless steel wire brushes with blue colour plates.
