What Are The Recommended Rpms For Different Types Of Power Brushes

DRIVING BRUSHES NEEDS HORSEPOWER

Horsepower requirements for driving a power brush are often determined by four factors:

• The need for a strong brush.
• Resistance (trim length) between the work surface and the brush.
• The brush's speed.
• width of the brush face.

The amount of horsepower needed for wide-face brushes depends on the relative brush load. Short-trim brushes typically require more horsepower than long-trim brushes.

BRUSHING ACTION

Power brushing conditions are subject to several variations. Many times, using one or more power brushes will yield the same results; nevertheless, if using only one brush does not yield the intended outcomes, consider the advice below:

RESULTS CHANGES AIM FOR

• Change in brush suggested.

QUICKER ACTION

• Speed up your brushing.
• Employ thicker filament or wire.
• Use a brush that has been trimmed short.
• Increase RPM or use a wider brush.

SUPERIOR FINISH

• Employ finer filament or wire.
• Try using a nylon filament brush or Tampico.

REACH UNUSUAL SURFACE AREA

• For increased versatility, use a brush with a longer trim length.

REDUCED LIFE

• Use longer trim and finer wire.

INSTEAD OF ROUGHING OR PREENING IT, REMOVE THE BURR

• Boost the brush's speed.
• Use a shorter brush.
• To check if the tips are cutting or wiping, check the brushing pressure.

Note: The brush's rotational speed is crucial. (See the Surface Speed Table).

TOOLS THAT ARE PORTABLE

Brushes with a maximum recommended diameter of 6" should be used with electric or air-powered portable tools.
