A 90mm precision tube finishing line, supplied by Mair Research Spa, Italy, has been successfully commissioned at Jansen, Oberriet, Switzerland. Mair Research has supplied many highly customised, special finishing lines to Jansen over the last 15 years; the highlight of this particular supply is the 10-roll straightener, which has been developed to meet the particularly stringent requirements of the customer. The recently commissioned equipment is placed off line and processes maximum 90mm diameter tube, 6mm wall thickness and 13.5m length. Tubes are loaded into a bundle unloader with special descrambling features, which supplies a 10-roll straightener, linked to a finishing line composed of ultrasonic testing, multicut to reach final length, tube ends de-burring, tube washing/rinsing and two automatic bundling systems, one for short tubes (max 2m length) and one for long tubes (over 2m up to 8m length).

Giant billet saw built at Otto Fuchs HERTWICH Engineering, Austria, a company of SMS Meer, Germany, has successfully commissioned its largest billet saw to date at Otto Fuchs KG, Meinerzhagen, Germany. This saw plant stands out for its size and is designed to process cast billets with a diameter of 700mm and up to seven tons in weight. The saw blade measures 1,920mm in diameter and is powered by a 149kW drive motor. Cut lengths are between 200 and 2,000mm, besides test slices of 30mm thickness. All cut pieces are automatically pin marked and stacked into the customer’s standard frames. The bulk of the production is blocks of 400 to 2,000mm length, which are later forged into automotive and aerospace components. Shorter blocks of 200 to 400mm are cut as forging stock for alloy wheels. SMS Meer – Germany Email: thilo.sagermann@sms-group.com Website: www.sms-meer.com
