Five Tips for Cutting Finishing Costs with NamPower Wheel Brushes

NamPower Wheel BrushesFor parts deburring, surface finishing, and edge radiusing, NamPower wheel brushes get great results. Brush Research Manufacturing's  NamPower wheels have molded cores for higher filament densities. This balanced construction puts more cutting tips at the point of attack for better brush performance, less filament breakage, and more even brush wear.

NamPower composite hub wheel brushes are also safer than wire wheels. Plus, NamPower wheel brushes offer a performance advantage over non-woven abrasive brushes. The NamPower Resource Guide provides complete information about NamPower wheel brush selection and use, but this blog entry outlines five tips for cutting finishing costs with these high-performance nylon abrasive brushing tools.     

1. Begin with the Base Material

NamPower Diamond Wheels.jpgNamPower composite hub wheel brushes feature nylon filaments with either silicone carbide or diamond abrasive. The base material of the workpiece determines which abrasive type to select.  Use silicon carbide abrasive for industrial metals like aluminum and steel. Use diamond abrasive with hardened tools steels, high-speed steels, carbide, plasma-sprayed, and nitride-coated surfaces.   

2. Get a Grip on Grits and Mesh

Your surface finishing requirements determine which grit or mesh size you need. Silicon carbide abrasive comes in coarser and finer grit sizes. Choose coarser grits for heavy-duty deburring, or when a finer finish is not required. NamPower diamond abrasive wheel brushes come standard in 600 mesh, but additional mesh sizes are available upon request.

3. Go Larger than the Cutting Tool

NamPower Wheel BrushDid you know that the diameter of a NamPower wheel brush should be larger than the cutting tool that was used to machine the part? Remember this tip when ordering silicone carbide wheels, which come in 6” (152 mm) and 8” (203 mm) diameters; or when ordering diamond abrasive wheels, which come in 4” (100 mm), 6” (150 mm), and 8” (200 mm).  

4. Be Flexible or Get Aggressive

Tool diameter also determines whether a NamPower wheel brush is more flexible or more aggressive. As a rule, larger-diameter tools are less aggressive and more flexible. Smaller-diameter wheel brushes are less flexible and more aggressive. Trim length affects flexibility and aggressiveness, too. Longer trim lengths are more flexible. Shorter trim lengths are more aggressive.

5. Use a Coolant If You Can

NamPower composite hub wheel brushes can be used with or without a coolant. Heat adversely affects the life and performance of nylon filaments, however, so use a coolant whenever possible – especially at high speeds.
