  • a centrifugal barrel finishing apparatus as claimed in claim 1 further comprising at least one feeding means positioned around the periphery of said turrets for feeding parts to be finished and a polishing media into a tub stopped at the position of the feeding means.
  • a centrifugal barrel finishing apparatus as claimed in claim 8 in which said feeding means is an annular trough extending around the turrets and having feeding chutes extending downwardly therefrom toward the tubs and at positions corresponding to the positions of the tubs on said lower turret when said turrets are stopped, hoppers above said annular trough for feeding parts and abrasive media into said trough, and vibration generating means associated with said trough for vibrating the media and the parts in said trough.
  • said feeding means is an annular trough extending around the turrets and having feeding chutes extending downwardly therefrom toward the tubs and at positions corresponding to the positions of the tubs on said lower turret when said turrets are stopped, hoppers above said annular trough for feeding parts and abrasive media into said trough, and vibration generating means associated with said trough for vibrating the media and the parts in said trough.
  • a centrifugal barrel finishing apparatus as claimed in claim 9 in which said trough is divided into two annular portions, one for polishing media and one for parts.
  • a centrifugal barrel finishing apparatus as claimed in claim 8 in which said feeding means comprises means for preparing a quantity of compound solution, finishing media and parts to be finished, a measuring box into which said quantity is fed, and liquid level measuring means in said measuring box for measuring the amount of the mixture fed into the box and discontinuing the feed when a predetermined amount has been fed.
  • a centrifugal barrel finishing apparatus as claimed in claim 1 further comprising an annular transporting and separating means around said lower turret having a trough extending in an annular path and having an end lying adjacent the annular path, a plurality of chutes spaced therearound at intervals corresponding to the spacing of the tubs around the turrets so that when the tubs are pivoted they discharge the contents into said chutes, vibrating means operatively associated with said annular transporting and separating means for transporting the contents of the tubs therealong toward said end, and a screening means at said end of the annular transporting and separating means for separating the media and the parts.
