Abstract
A tool magazine assembly for a machining center holds multiple tool holders and has an outer ring, an inner ring and multiple brackets. The inner ring is mounted in but does not contact the outer ring and has multiple through holes. The brackets are attached to the inner ring, and each bracket has multiple through holes, a central hole, multiple fastening holes, multiple bolts and a central bolt. The bolts extend through the through holes to attach the brackets to the inner ring. The central bolts extend through the central holes between the inner ring and the outer ring. Each tool holder has multiple bolts. The bolts extend through the fastening holes to attach the tool holders to the brackets.
