Bow ring ball finishing device and bow ring ball finishing method

摘要

A bowling ball surface treatment machine includes a housing and a ball movement guider provided inside the housing for guiding movement of a bowling ball, the ball movement guider having a guider center axis and an inner circumferential surface. A surface treatment disc with a surface treatment is arranged below the ball movement guider for supporting and rotating the bowling ball. The surface treatment disc has a disc center axis deviating from the guider center axis. The machine further includes a disc driving motor for rotating the surface treatment disc about the disc center axis and a controller for allowing the disc driving motor to repeatedly accelerate the surface treatment disc to a target rotation speed, rotate the surface treatment disc in a surface treatment position at the target rotation speed for a predetermined running time and then decelerate the surface treatment disc toward a zero speed.
