Nampower Brushes

January 12, 2012

Brush Research Manufacturing has introduced a unique new line of Nampower abrasive nylon brushes that contain a combination of ceramic and silicon carbide filaments to deliver maximum burr removal rates and ideal surface finish in one operation.

The abrasive filaments on Brush Research's Nampower Tools work like flexible files, conforming to part contours, 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.

These abrasive brushes are easily integrated into today's automated machinery, CNC machining centers, transfer lines and robotic cells used for machine inline deburring (MID), edge radiusing and surface finishing.

Typical applications for Nampower Tools include removing burrs and blending tool marks in punched and fine blanked components, deburring face milled surfaces, improving surface finish, edge radiusing and blending. Typical components finished include cylinder heads, bell housings, pump housings, gears, fine blanked parts and stamped components Industries that would be interested in this product include aerospace, automotive, industrial, medical and robotics.

Nampower Tools are available in 2 different fill configurations: Dot Style for general purpose deburring and surface finishing applications and Turbine Style for medium and heavy deburring applications. The Dot style is an economical choice for light deburring applications when short cycle times are important. Dot style brushes provide greater flexibility and allow entry into small holes and spaces with ease. The Turbine style brush has a high density fill that is ideal for short cycle times and long tool life.

Both Dot style and Turbine style disc brushes are designed for use with the new "Flow Through Coolant" holder. This professional grade tool holder 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 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 100mm, 125mm and 150mm diameters. Two trim lengths are offered, either 18mm or 38mm. Shorter trim lengths result in more aggressive cutting where heavy burrs are present and longer trim lengths allow irregular surfaces to be finished easily. Grits include 80, 120, 180 and 320.

Nampower Tools are manufactured with a molded fiber reinforced thermoplastic base that reduces vibration, resulting in a more balanced tool that provides improved tool performance, greater process repeatability, increased safety and longer tool life.

Related Glossary Terms

  • abrasive


    Substance used for grinding, honing, lapping, superfinishing and polishing. Examples include garnet, emery, corundum, silicon carbide, cubic boron nitride and diamond in various grit sizes.

  • burr


    Stringy portions of material formed on workpiece edges during machining. Often sharp. Can be removed with hand files, abrasive wheels or belts, wire wheels, abrasive-fiber brushes, waterjet equipment or other methods.

  • centers


    Cone-shaped pins that support a workpiece by one or two ends during machining. The centers fit into holes drilled in the workpiece ends. Centers that turn with the workpiece are called “live” centers; those that do not are called “dead” centers.

  • computer numerical control ( CNC)

    computer numerical control ( CNC)

    Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.

  • coolant


    Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.

  • filing


    Operation in which a tool with numerous small teeth is applied manually to round off sharp corners and shoulders and remove burrs and nicks. Although often a manual operation, filing on a power filer or contour band machine with a special filing attachment can be an intermediate step in machining low-volume or one-of-a-kind parts.

  • robotics


    Discipline involving self-actuating and self-operating devices. Robots frequently imitate human capabilities, including the ability to manipulate physical objects while evaluating and reacting appropriately to various stimuli. See industrial robot; robot.
