GRINDING DEVICE AND ARRANGING METHOD FOR CHUCKING PINS OF THE SAME

摘要

A grinding device and an arranging method for chucking pins thereof are provided to predict arrangement state of chucking pins directly and without separation of ferrule, and to predict arrangement state of chucking pins exactly by measuring data related to an object for grinding, and to move chucking pins precisely. A grinding device comprises: a pair of chucking pins(110,130) supporting both ends of an object rotatably, a grinding unit grinding the object, a measuring unit(700) predicting arrangement state of the chucking pins by measuring at least one of change of an outer diameter of the object and the force applied to the object while the object is grinded, and a transfer unit(910,930) changing relative positions of the chucking pins in response to the arrangement state of the chucking pins predicted by the measuring unit.
