Additional Information

Abrasive nylon disc brushes work best at speeds allowing fairly deep penetration of the work piece into the brush filaments. Faster speeds do not typically work as well as slower speeds, since the maximum RPM listed on the brush is not the optimum working speed. A good rule of thumb is to stay below 2,500 SFPM in dry applications and 3,500 SFPM with coolant.Rotational DirectionOn the initial pass of the brush, rotation should be in the opposite direction of the cutting tool that created the burr. Brush should overlap edge of working piece by 1" minimum.Brush PathThe ideal brush path is in the opposite direction of travel from the cutting tool that created the burr. The brush path should also be longer than the cutting tool path, to a point where the trailing edge of the brush is effective on the end of the part. Lastly, to maximize the amount of filament that is striking the part, the center line of the brush should be offset from the center of the part.Penetration (Point of Contact)The abrasive action occurs when the sides of the brush filament slide across the part surface or edge of the part. When the correct balance between speed (RPM), penetration, dwell time and abrasive grit size are achieved, then optimum life and cut can be obtained. Recommended penetration rates for abrasive nylon disc brushes are from 0.075" to 0.100". This will allow long brush life with aggressive abrasive action.
