Abrasive Nylon Disc Brushes—A Single Tool Removes Burrs, Improves Surface Finish

May 1, 2012

Brush Research Manufacturing, Los Angeles, CA, introduces a unique new line of Nampower abrasive nylon brushes that contain a combination of ceramic and silicon-carbide filaments to—in one operation—deliver optimum burr-removal rates and ideal surface finish. The abrasive filaments on the Nampower tools work like flexible files, conforming to part contours and wiping and filing across part edges and surfaces. Because of the 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 the bristles. 

The abrasive brushes are easily integrated into automated machinery—CNC machining centers, transfer lines and robotic cells used for machine inline deburring, edge radiusing and surface finishing. Typical applications include removing burrs and blending tool marks in punched and fineblanked components and stamped parts; deburring face-milled surfaces; improving surface finish; edge radiusing; and blending. 

Nampower Tools are available in two different fill configurations: Dot style for general-purpose deburring and surface-finishing applications; and Turbine style for medium and heavy deburring. The Dot style is an economical choice for light deburring when short cycle times are important. Dot-style brushes provide optimum flexibility and allow entry into small holes and spaces with ease. The Turbine-style brush has a high-density fill, ideal for short cycle times and longer tool life.

Both styles of brushes are designed for use with the new Flow Through Coolant holder, a professional-grade tool holder that allows coolant to flow from the brush center instead of supplying lubricant only from the outside. Center coolant flow results in better lubricant dispersion, which reportedly permits the brush to run at greater cut depths and drastically reduces heat generation. Reduced heat generation eliminates filament smearing, improves surface finish and promotes long brush life.

Nampower Tools are available in diameters of 100, 125 and 150 mm diameters. Two trim lengths are offered—18 or 38 mm. Grits: 80, 120, 180 and 320.
