METHOD FOR MANAGING ACCURACY OF TURRET

摘要

Disclosed is a method for managing accuracy of a turret efficiently managing a horizontal state in each portion of a turret. The method for managing accuracy of a turret includes the steps of: measuring a reference position of at least three points to select a center line of a lower bearing support surface and a lower measurement surface in the lower bearing support surface of the turret; measuring an upper position of at least three points to select an upper measurement surface of an upper bearing support surface in the upper bearing support surface of the turret supported by an upper bearing; correcting the upper measurement surface to be parallel to a horizontal reference surface on the basis of the center line; and processing the upper bearing support surface along the corrected upper measurement surface.
