摘要：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.
主权项：1. A method for producing a variable turbine geometry for an exhaust gas turbocharger, comprising: arranging a first and a second guide vane support ring coaxially and axially at a distance from each other; and 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; wherein the at least one first guide vane bore and the at least one second guide vane bore are configured to adjustably receive a guide vane of the variable turbine geometry.
