Arinox concludes production expansion plan ARINOXSpA, a company of theArvedi Group, has concluded an important production development and expansion plan consisting Endworking of pipes and tubes by CNC machine tool ARLA Maschinentechnik GmbH, Germany, builds CNC-controlled endworking machines that are available for single- sided and double-sided machining. The machine concept is based on a solid frame with one or two precise machining units, including a unique concentric work-holding technology. The machine works like two separate CNC lathes, operating independently for each side. The principal difference is that this endworking concept comprises a fixed workpiece and revolving tools. All machining units are directly driven by servomotors and are therefore stiff, powerful and designed for high torques. In order to realise several machining steps, the units are built with integrated motor spindles, optionally available with tool changing systems. Typical applications are OD and ID turning, facing, planing, tapping, bevelling, threading, grooving, chamfering, boring, drilling and milling – in particular for the welding end preparation of pipes and tubes. The new series of ARLA spindle units can be used either with HSK interface or with integrated facing heads. The machining of complex contours with a single tool system is realised by facing heads that are implemented in ARLA’s DX machining units, as used for welding end preparations.

of the installation of new production and finishing lines for precision rolled stainless steel thin strip in width 1,270mm. Arinox stainless steel strip is aimed mainly at sectors of application with high technological content such as the car, chemical, petrochemical, electronics, precision mechanics and biomedical industries. This important investment plan has led to the installation of a new 20-hi Sundwig rolling mill, an Ebner bright annealing (BA) line with in-line tension leveller, a new

Ungerer tension levelling line and new automatic packaging lines serving the new cutting lines. Arinox, having completed this expansion phase, has now acquired an overall production capacity of more than 50,000 tons/year of precision strip and with the widening of its size range has increased its competitive edge.
