The machining center of a numerical control machine tool according to claim 9, wherein a second long axis end of the oval track, which is located outside the machine tool bin body, is recessed downward, when the sliding rod slides to the second long axis end along the oval track, each elastic unit drives the corresponding sliding rod and the abutting part to slide away from the center of the machining table, and each wedge block and the rotating ring are rotated in a second direction, which is a rotation direction opposite to the first direction, and the spiral groove is in sliding fit with the top of the sliding rod, so that the sliding rod moves downward relative to the machining table to abut against the second long axis end; when the sliding rod is positioned at the second long shaft end, each abutting part slides away from the center of the machining table to the maximum extent; when the sliding rod is positioned on the oval track between the first long shaft end and the second long shaft end, the abutting parts pre-clamp the workpiece; when the slide rod slides to the first long shaft end, each abutting part abuts against the workpiece, so that the workpiece is locked on the processing table.
