The invention relates to a machining center coordinate origin offset error and boring position degree testing method. The method comprises the following steps: 1) pre-machining a test piece; 2) positioning a test piece and determining a processing coordinate system; 3) processing a test piece detection reference; 4) no-load and load operation of the machine tool; 5) processing the detected features of the test piece; and 6) detecting errors of the test piece. According to the method, the machining process of a test piece is reasonably planned and designed, and the machining process is divided into three parts according to the time sequence, namely test piece detection reference machining, machine tool no-load and load operation and test piece detected feature machining. The machining precision of the test piece can fully display the machine tool precision retentivity, especially the coordinate origin offset error and the boring position degree, so that the machine tool precision test work is more comprehensiv
