Takes too long to achieve desired effect

Possible solutions:

  • Increase surface speed by:
    • increasing brush diameter
    • increasing brush speed
  • Use stiff brush fill material by:
    • decreasing trim length
    • using heavier wire or fiber
    • increasing density of fill

Note: Do not use greater work pressure.

Finer finish wanted, or undesirable side effects encountered such as removal of base material

Possible solutions:

  • Use more dense fill in brush
  • Decrease effective fill hardness by:
    • using finer fill material
    • using fiber or plastic rather than wire (sometimes with compound)
    • use softer type of wire i.e. brass

Use less pressure on workpiece.

Getting too much wire breakage during operation

Possible solutions:

  • Use finer diameter wire and increase spindle speed
  • Decrease trim length
Brush wears down too rapidly

Possible solutions:

  • User harder fill material
  • User denser fill in brush
  • Decrease workpiece pressure
Brushing effect not even or uniform

Possible solutions:

  • Use jog or fixture to assure steady application on workpiece
  • Increase spindle speed
