DISC FINISHING MACHINES Processing is carried out in an open drum (the process container) with a base plate in the form of a turntable or disc. The work pieces, together with a suitable polishing or grinding granulate, are set in motion by the rotation of the disc to create a toroidal stream inside the stationary [...]

MACHINES FOR THE MASS FINISHING PROCESS Mass finishing is a surface finishing process used mainly for metallic work pieces. When finishing bulk materials, the work pieces are placed inside a process drum together with a grinding or polishing medium and a normally aqueous mixture (compound). The oscillating or rotary motion of the drum creates relative [...]
