Composite Hub Wheel Brushes

NamPower™ composite hub wheel brushes are abrasive nylon brushing tools for machine-based and off-hand deburring, surface finishing, and edge radiuses. These safe, dependable radial wheel brushes feature indestructible cores, higher filament density, and balanced construction.

An alternative to wire wheels and non-woven abrasive brushes, NamPower composite hub wheel brushes are used in the production of turbine blades, steel gears, machine parts, and cam shaft and cutting tool inserts.

As part of the new NamPower family of abrasive nylon brush tools from Brush Research Manufacturing Co., Inc. (BRM), NamPower composite hub wheel brushes feature flexible nylon filaments set in a strong thermoplastic base. Nylon filaments uniformly filled with silicon carbide abrasive remove loose, torn, and folded metal while providing maximum burr removal and optimum surface finish.

Composite hub construction allows for greater fill density, more uniform fill density and produces a brush that has more cutting points. Composite hub construction results in a more balanced brush that produces less vibration and greater process repeatability.

NamPower wheel brushes are ideal for removing sharp edges from metal parts and creating a desired edge radius. When selecting Composite hub wheel brushes, as with all industrial brushes, it is important to consider with the proper diameter, face width, and trim length.

The brush’s face width must be wide enough to deburr a wide edge but the tool’s tips should be narrow enough to access part recesses that also may require material removal. The abrasive grit is also important to consider. Trim length and filament diameter affect flexibility. The coarser the abrasive grit (lower number), the bigger the filament diameters has to be.

NamPower™ composite hub wheel brushes are available in two diameters: 6 in (152 mm) and 8 in (203 mm). Both have a standard two-inch arbor hole for use with in-line machining and deburring systems. Adaptors are available for other arbor hole sizes. The wheels are available with face widths of either 1/2 in or 1 in. Trim lengths for BRM’s NamPower wheel brushes are 1.5 in and 2.5 in. Choices for grit (filament diameter/grit size) include 0.18/500 SC, 0.22/120 SC, 0.22/320 SC, 0.35/180 SC, and 0.40/120 SC. www.brushresearch.com
