Grain Type

S/C or A/O

Grit

60#-1200#

Grain type and Grit:

While non-wovens are made in a different way than conventional coated abrasives, both types of products use many of the same abrasive minerals. Silicon carbide is sharper, cuts faster and produces finer scratch patterns on most surfaces. Aluminum oxide is more durable and tends to last longer. It is more aggressive on certain applications (such as hardened steel parts), and produces less discoloration on aluminum. When the non-woven supplier talks about grit, he is referring to the size of the abrasive grain impregnated into the nylon web. The lower the number, the larger the grains. Use of large particles (coarse grit) results in a more aggressive cut and a coarser finish. Small size particles result in a non-woven product that produces fine surface finish, if all other conditions are equal. In specifying a conventional bonded or coated abrasive product, the purchaser selects a specific grit size – say, 120 grit. 

Density:

Another term used in specification that is probably unfamiliar to the buyer of conventional abrasives is density. This refers to the amount of bonding agents and amount of abrasive grain that have been compressed into the non-woven product. In general, harder density products cut faster, last longer and produce finer finishes than softer density products. However, softer densities offer more conformability to the work surface and less tendency to load or burn the workpiece. Two other factors in the design and manufacture of non-woven abrasives are the sizing of the nylon fibers and the bonding agents used. Fiber size has a significant effect on the product’s cutting characteristics, while the type of waterproof resin used to bond the fibers together (and to anchor the abrasive to the web) can alter the characteristics of the product. The non-woven manufacturer selects the appropriate fiber size and bonding agent based on the intended application for the product; therefore, these components are not included in the product offering specifications.

Soft density Unitized Wheels 3P, 4P, 5P                                                                                                • polish mechanical parts (jet blades, threads, welds, casted parts) smoothing edges
 • cleaning rust, discoloration, coatings
 • blending marks or scratches

Medium density Unitized Wheels 7P, 9P                                                                                               • polish mechanical parts
  • light deburring or reduction edges
  • blending marks or scratches
  • cleaning scales or oxidation

Hard Density Unitized Wheels 12P, 14P, 16P
  • heavy deburring
  • reducing sharp edges
  • blending heavy marks or scratches
  • cleaning scale or oxidation
