Golf ball deburring method

摘要

A molded golf ball having burrs in a region of its surface is ground using a grinding head having an abrasive surface of a sufficient width or diameter to cover the burr-bearing region of the golf ball surface and a drive mechanism for driving the grinding head. The drive mechanism is actuated to drive the grinding head to bring and force the abrasive surface against the burr-bearing region of the golf ball surface for grinding away the burrs. The point of time when the drive mechanism experiences a load change beyond the predetermined value is detected by a control unit to deliver a signal representing the substantial completion of grinding, in response to which the grinding step is terminated.
