As a system supplier, Grüner buys castings on the market on a project-by-project basis and delivers the fully machined and, if necessary, assembled component to the customer. The entire process chain is the company‘s core competence and is mapped out with its own know-how – from development and design to the finished component. The specially developed machining centre solution with multi-spindle head machining is highly flexible and productive. Newly developed additional magazines for the machining tools enable extremely fast changeover (one-piece flow). The flexible design of the mechanical processing and all subsequent processes enables the production of a wide variety of products with a wide range of variants. Due to this specific design of the manufacturing and testing processes, the Grüner Business Group is the benchmark for the machining of aluminum and magnesium castings.
