Patent ID: 7585203

Claim:
A bowling ball surface treatment machine, comprising: a housing; 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 for guiding movement of the bowling ball; a surface treatment disc arranged below the ball movement guider for supporting and rotating the bowling ball, the surface treatment disc including a surface treatment element for making frictional contact with the bowling ball, the surface treatment disc having a disc center axis deviating from the guider center axis of the ball movement guider; 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 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, in a repeated manner until a preset treatment time lapses.
