Operators have control over five factors: conveyor feed rate, abrasive type, abrasive speed, brush composition, and brush speed. A slow feed rate is good for deburring because it gives the abrasive more time to work over the edges. A high feed rate is for graining, or finishing the surface. Slowing the process increases the life of the belts and brushes, but at the risk of sacrificing edge quality. It's all about balance. To break an edge, slow the machine and use the abrasive belt only. For even belt wear; run parts across the entire width of belt, not just down the center. To be sure all edges get a thorough deburring, send parts through at angles. Aligning a square or rectangular part with the feed direction means that two of the edges are perpendicular to the direction of brush rotation and get a good deburring.
