56 SHUR-BRITE Convolute

Convolute Characteristics
Used for deburring, cleaning, blending and polishing SHUR-BRITE® Convolute Deburring Wheels utilize their compressed
nonwoven structure as a three-dimensional cutting tool . Fresh abrasive grains are continually exposed, providing a consis-
tent, uniform finish on various materials, including ferrous, non-ferrous, stainless and exotic alloys .

Nylon fibers, abrasive grains and resins are bonded together in thin layers, then convolutely wrapped around a center core .
The tension of the wrap controls the density of the wheel . Due to the convolutely wrapped design, debrring wheels are one-
directional and used with stationary machines .

Understanding Material Grades

Wheel Density Wheel density also translates to 2 9
flexibility and conformity . Lower Softer, more conformable Harder, more durable
densities will not alter workpiece ge- Light Deburring/

Grain Type Aluminum oxide grains are dens-
er, allowing higher pressure, and
recommended for softer ferrous or A S
non-ferrous materials . Silicon car- Durable, long lasting Sharper, finer scratch pattern

Grain Size The abrasive grain size used in
each wheel controls the depth and Coarse Medium Fine
refinement of the scratch . Due to the (60-80) (100-150) (180-220)
nonwoven construction, convolute
wheels will usually finish 2-3 grits Faster cut, rougher finish Reduced cut rate, finer finish
