What does a Machine Finisher do?
Tends sanding-and-buffing machine that smooths and polishes surface of plastic sheets to specified finish: Installs sandpaper belt in machine and sets tension of buffer springs to regulate pressure of buffers on sheets, using wrench. Starts machine and feeds sheets into machine. Observes ammeter to verify machine load specified for sanding. Verifies thickness of finished sheets, using dial indicator micrometer. Examines surface of sheets for defects, such as scratches, dull spots, and cracks.
