PRODUCT
Scotch-BriteTM SF Finishing and Deburring Wheel Grade 8S FIN 6" x ½" or 8" x ½"
Products Replaced
Competitive deburring wheels or rubber bonded wheels.
Advantages/Benefits To Customer
Fast and Consistent A unique resin system allows the SF wheel to contain more mineral than typical deburring wheels, meaning the SF cuts faster and lasts longer. [. . . ] SF wheels are designed to quickly remove coarse abrasive scratches and small milling lines and defects while providing a burr-free, blended, consistent bright satin finish.
Typical Process
Small industrial gas turbine blades are forged. After forging, subsequent processing includes CNC milling which leaves milling lines and metal burrs on the parts. The surface of the blades are abraded and blended to a uniform finish as preparation before going into vibration media for final finish. Historically, deburring wheels or rubber bonded wheels are used to remove metal scale, milling lines, and minor surface defects while trying to provide the required surface 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. Rubber bonded wheels are often not aggressive enough, meaning the process is slower and more tiresome for operators. Scotch-Brite SF Wheel will quickly remove small milling lines and surface defects and blend the surface of the blade to 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.
