User manual 3M 02-2004 REFINING A COATED ABRASIVE FINISH ON HAND TOOLS

[. . . ] Application Profile Market: Hand Tools Application Description: Refining a coated abrasive finish on hand tools 241317 Key Application Requirements Refine a coated abrasive finish to provide a final satin finish on hand tools. Long wheel life without smearing, even in the presence of burrs. [. . . ] SF wheels are designed to quickly remove coarse abrasive scratches, blend, and provide a burr-free, consistent bright satin finish. Typical Process Hand tools are forged of tool steel. After forging, parts are refined by grinding with a series of ceramic aluminum oxide and aluminum oxide coated abrasive belts. After the last coated abrasive step (usually grade 120­180), the finish requires refining, removal of small burrs and surface defects to a final satin finish. Historically, deburring wheels or fine grade coated abrasives are used for refining the finish. Deburring wheels, which are higher densities, can be difficult to work with. Higher density wheels have a tendency to bounce and chunk, which is tiring for operators to run and can require frequent dressing. Deburring wheels also require metal burrs to act as a mechanism to dress the face of the wheel and expose fresh mineral. Coated abrasive belts will often leave small burrs on the part, which can result in metal slivers during use of the hand tool. Scotch-Brite SF Wheel will quickly remove coarse abrasive scratches, blend, and provide a burr-free, consistent bright finish. SF wheels resist smearing, provide long wheel life even in the presence of burrs and are user-friendly for operators.
