Abstract
A barrel-type finishing machine provides the fully automatic functions which permit the finishing process such as surface finishing, radiusing, gloss polishing, etc., and other associated operations to be performed for each succeeding cycle of the sequence of those operations. The machine includes a dual barrel structure consisting of an upper stationary container of a cylindrical shape and a lower rotary shallow container of a tray shape which are partly or wholly movable up and down relative to each other; and an annular mass receptacle trough surrounding close to the dual barrel structure and including means for causing the mass receptacle trough to be moved up and down, means for separating the mass into workpieces and abrasive media, means for returning the abrasive media for reuse, and vibration generating means for placing the mass collector conduit under vibration, means may be included for controlling the toroidal flow of the mass inside the dual-barrel structure by producing a centrifugal force. For the wet type finishing application. The machine further include means for preventing leaks of compound solution from the dual-barrel structure from entering the rotary shaft b…
