Wipers mount on the moving platform to "wipe" debris off the track
before the platform moves over the track. Metal filings can cause wear
and friction if not kept clean. With a machine like a bridgeport with
such tight tolerances, keeping the tracks clean and guarding the track
/ platform opening is important for use and longevity of the machine.
