Bewo has recently launched its new SCF 90 Quatro automatic circular saw tube re-cutting machine, which is capable of re-cutting tubes at up to 6,000 pieces per hour. The SCF 90 Quatro can cut up to four tubes at once (depending on diameter), using a high speed, servo drive controlled tube feeding carriage to transport a pack of tubes at up to 13ft/sec, to the required re- cutting length.

Geared to producers of seamless stainless steel tubing, Banyard will exhibit a display featuring the Banyard VSI (vertical steel induction) billet heating system. This equipment is designed for the precision heating of large diameter stainless steel tubes or billets prior to extrusion. With the VSI system, varying billet lengths are automatically processed to a very precise level of temperature uniformity inside a vertical, multi-tapped induction coil. This is powered by a well proven Inductotherm VIP power unit.

Attl a Spol has been in the metals business since 1920. The company produces mills for longitudinally welded tubes and profiles, using components of its own design.

› Bewo’s SCF 90 Quatro can cut four tubes at a time

Bema offers the new CNC end-forming machine, branded SER 6 x ‘n’ CNC (universal version ‘BVR’) with CT 1300 universal feeder. The machine – able to automatically end-form both sides of the tube – is equipped with a vertical clamping device, rotating units and chip container. With a maximum 6t operating power, the machine is designed for tubes with a maximum Ø 90mm. A device with N working stations (minimal 8), the hydraulic/ electric machine is completely automatic on 3 axes. Different heads can be used, together with a connection to an automatic feeder and/or robot. The end-forming machine can be interfaced with Bema’s new Reverse 25 DS Elektra CNC bending machine. This fully digital and automatic machine has 12 axes for bending pieces with formed tube ends. The patented all-electric bending machine has an integrated feeder and unloader, with 2 bending-heads. It is equipped with a numerical control module ‘ipc rainbow’. The machine operates with right/left bending in the same cycle without the need to remove the tube. To help reduce setup time, the Reverse 25 DS has a number of ‘N’ tools permanently mounted on the machine (minimum of 6).

Of particular interest are the company’s vertical accumulators, flying shear and flying cold saw, HF welders and bundling machines.

Unlike conventional tube re-cutting solutions, the SCF does not require the use of target stops to define the required cut length. Instead, the servo drive CNC carriage allows the re-cutting list to be pre- programmed, via a full colour, graphical operator display. The saw is part of a complete production cell including integrated brush deburring, non-contact tube length measuring and a 4 axis robotic pick and place tube packing system.

Axxair offers expertise in orbital cutting, bevelling and welding of tubes, based on two industrial patents – one for its concentric clamping system and the other for carbide tip bevelling. The company also excels in orbital prefabrication welding. Following successful ‘V’ orbital bevelling, the company is taking the advanced technology further, with bevelling in ‘J’, a suitable preparation step for orbital welding of tubes (thicker than 3mm). This includes a new SASL-200 generator equipped with touch display, computer assisted programming, AVC option and oscillation.

Blissenbach manufactures the new impeder ‘safe coat’ system. This system ensures that the crucial part of the impeder (the epoxy glass impeder casing), is better protected against the heat and hot spatter from the weld zone. Due to the growing demand of return flow impeder systems (which are mainly used for small tubes or high carbon materials),

Axxair recently created two subsidiaries and three offices abroad.
