FAQ

Brush wires

wires
steel wire:
 for processing metal surfaces
twist knotted steel wire:
 particular tough and aggressive
crimped steel wire:
 soft and flexible, aggressivity depends on wire strength
stainless steel wire:
 for cleaning stainless steel surfaces
brass wire:
 for cleaning delicate or brass surfaces
filament grit:
 for polishing, grinding and structuring from fine to medium grades

table for rotational speeds

Rotational speed depends on rpm speed and brush diameter.

Problems occurring during work

Problems occurring during work
Brushing effect is not substantial enough: 1.increase rotational speed by:
    a)using larger diameter
    b)increase rpm
2.use brush with shorter wire length
3.use brush with thicker material (e.g. use 0.35 wire instead of 0.30 or choose filament grit 120 instead of 180).
Brushing effect too substantial: 1.decrease rotational speed by:
    a)using smaller diameter
    b)decrease rpm
2.use brush with longer wire length
3.use brush with less thickness (e.g. use 0.30 wire instead of 0.35 or choose filament grit 180 instead of 120).
Result is too coarse: 1.increase rotational speed by:
    a)using larger diameter
    b)increase rpm
2.use brush with shorter wire length
3.use brush with thicker material(e.g. use 0.35 wire instead of 0.30 or choose filament grit 120 instead of 180).
Result is too sensitive: 1.decrease rotational speed by:
    a)using smaller diameter
    b)decrease rpm
2.use brush with longer wire length
3.use brush with less thickness (e.g. use 0.30 wire instead of 0.35 or choose filament grit 180 instead of 120).
