Abstract
A barrel finishing machine includes a dual barrel structure including a cylindrical stationary container and a rotary container concentrically mounted in the stationary container for rotation, with a small gap between them. Linings are formed from an elastic material and are provided to cover inner surfaces of the stationary and rotary containers respectively, and a stopper is mounted in the lining of the rotary container at a position in the vicinity of an outer circumferential edge of the rotary container. The stopper is effective to restrain expansive deformation of the lining of the rotary container due to thermal expansion. The stopper circumferentially rises from a base of the rotary container. The stopper member is detachably attached relative to the base of the rotary container.
