METHOD AND APPARATUS FOR WORKING ORIENTED-HOLE SYSTEMS IN NUMBER PROGRAM CONTROL MACHINE TOOLS Russian patent published in 2001 - IPC

FIELD: machine engineering, namely designs of number program control machine tools and working centers for combination working of body parts, covers, flanges, panels, plates, brackets and other parts with accurately oriented holes. SUBSTANCE: method comprises steps of drilling and further reaming at using multiposition spindle-tool turret head for single fixation of part. In order to improve accuracy before drilling in the same number program control machine tool, center-punching and centering are realized. At center-punching automatic center-punch is mounted in multiposition spindle-tool turret head. Apparatus includes multiposition spindle-tool turret head with tools set having drill and reamer for working oriented-hole system. In order to improve accuracy apparatus is provided with centering drill and automatic center-punch with spring-loaded striker arranged along axis of spindle of turret head coinciding with axis of drilling hole. EFFECT: enhanced efficiency of method, improved design of apparatus. 3 cl, 4 dwg
