Brush Research Manufacturing’s Nampower abrasive disc brushes contain a combination of ceramic and silicon carbide filaments designed for faster burr removal rates and improved surface finish. The abrasive filaments work like flexible files, conforming to part contours, and wiping and filing across part edges and surfaces. Because of its linear construction, sharp new grains constantly come in contact with the work surface and wear off, exposing fresh cutting particles. This provides consistent deburring action throughout the length of bristles.

The brushes can be integrated into automated machinery, CNC machining centers, transfer lines and robotic cells used for machine inline deburring, edge radiusing and surface finishing. They can remove burrs and blend tool marks in punched and fine-blanked components, debur face-milled surfaces, improve surface finish, and perform edge radiusing and blending. Applications include cylinder heads, bell housings, pump housings, gears, fine-blanked parts and stamped components in industries such as aerospace, automotive, industrial, medical and robotics.

The brushes are available in two fill configurations: dot style for general purpose deburring and surface finishing applications, and turbine style for medium and heavy deburring applications. Both styles are designed for use with a flow-through-coolant toolholder that enables coolant to flow from the brush center instead of only from the outside. This results in improved lubricant dispersion, which enables the brush to run at greater cut depths and reduces heat generation. Reduced heat generation eliminates filament smearing, improves surface finish and promotes long brush life, the company says.

The brushes are available in 100-, 125- and 150-mm diameters, and 18- and 38-mm trim lengths. Grits include 80, 120, 180 and 320.
