A method for producing a variable turbine geometry for an exhaust gas turbocharger may include arranging a first and a second guide vane support ring coaxially and axially at a distance from each other. The method may also include creating, by a boring process, at least one first guide vane bore in the first guide vane support ring and at least one second guide vane bore in the second guide vane support ring and aligned with the at least one first guide vane bore. The at least one first guide vane bore and the at least one second guide vane bore may be configured to adjustably receive a guide vane of the variable turbine geometry. 本发明涉及种用于生产用于排气涡轮增压器的可变几何涡轮(1)的方法，该方法包括以下步骤：a)共轴地布置第和第二引导叶片支撑环(2a、2b)，将它们轴向地彼此隔开距离；b)依靠相同镗孔处理在第引导叶片支撑环(2a)中创建至少个第引导叶片镗孔(4a)，以及创建对准该第引导叶片镗孔(4a)的第二引导叶片镗孔(4b)；其中，两个引导叶片镗孔(4a、4b)设计为用于可调节地接收可变几何涡轮(1)的引导叶片(5)。
