About SEMA Maschinenbau GmbH
Since 1988, SEMA Maschinenbau has been developing and manufacturing machine tools and automated production lines at its site in Traunkirchen in the Upper Austrian Salzkammergut region. The portfolio includes rotary transfer machines of the MT-C, MT-X, MT-V and MT-S series for high-volume production, end machining machines (ME series), flexible series production systems (MX-3) and customer-specific machining centers (Multi Custom Solutions). The systems cover the entire process from raw part to finished part: loading, pre-processing, machining (milling, turning, drilling, deep-hole drilling), deburring, cleaning and packaging, including handling solutions with industrial robots and gantry loaders. Materials are steel, aluminium and non-ferrous metals. Core industries are automotive, the metal goods industry, the electronics industry and rail transport. Critical machine components such as tool spindles, rotary tables and axis units are manufactured in SEMA's own component production. Projects are executed as turnkey projects from concept design through machining trials to commissioning at the customer's site.
