An automatic polishing machine which can polish a curved skin of a large area fully automatically and efficiently along a three-dimensional plane of the skin. The machine comprises a fixed horizontal beam, a movable table movable in a horizontal direction perpendicular to the beam for receiving thereon a work to be polished, a carriage mounted for movement on the beam, a slider mounted for up and down movement on the carriage, a turning member mounted for forward and backward turning movement within a predetermined angular range on an arcuate rail which is located at a lower end portion of the slider and has an upwardly swollen arcuate configuration, a rocking member mounted for up and down rocking motion on the turning member, a spindle supported for rotation on the rocking member, and a buff removably mounted on the spindle. The movable table, carriage and slider are moved by respective motors to move the buff to an aimed position, and the turning member is moved by another motor to move the buff to an aimed inclined position.
An automatic polishing machine, comprising a horizontal beam extending between upper portions of a pair of fixed vertical columns, a movable table for receiving thereon a work to be polished, said movable table being movable in a horizontal direction perpendicular to said beam, a carriage mounted for movement along a horizontal rail on said beam, a carriage driving mechanism including a motor for moving said carriage on said beam, a slider mounted for up and down movement on said carriage, a slider driving mechanism interposed between said carriage and said slider and including a motor for moving said slider up and down on said carriage, a turning member mounted for forward and backward turning movement within a predetermined angular range on an arcuate rail which is located at a lower end portion of said slider and has an upwardly swollen arcuate configuration, a turning member driving mechanism interposed between said turning member and said slider and including a motor for turning said turning member along said arcuate rail, a rocking member mounted for up and down rocking motion on said turning member, a spindle supported for rotation on said rocking member and connected to be rotated by a buffer rotating motor carried on said rocking member, means for oscillating said spindle and a buffer removably mounted on said spindle.
