Object tubing is a frequent application in the shipbuilding industry in general, especially in the hydraulics tubing. South East Asia still holds great potential in the wire & tube industry for growing despite unfortunate global financial crisis unavoidably affecting the region, says Ferruccio Bellina, President of the Italian Wire Machinery Manufacturers Association during the recent Wire and Tube South East Asia held in Bangkok, Thailand.

However, it is a fact that economic efficiency falls by the wayside if tubes are made-up at the object, manually drawn, bent on manual bending machines and built in. Since after the bending process, it is necessary to cut excess lengths, and this means a high loss of material. Moreover, a precise documentation is missing, the spent working time is high and the processed tube does not always fit.
transfluid Maschinenbau GmbH has designed an advanced economic solution for bending and processing of non-isometrized tubes.

"To guarantee a constant quality of the tubing and to achieve a minimal waste of material with shortest possible clamp lengths and small radii it is important to bend the tubes in a bending center", explains Gerd N?ker, transfluid CEO. "This not only provides for the ideal quality of the tubing but also makes possible a detailed documentation of the tube data."

But how do these bending respectively tube data come to the CNC bending machine? The provider of solutions transfluid created two different ways to directly compile a tube isometry that, for example, can be made available online (via network or e-mail) or manually (via usb flash drive) to the bending center and the bending machine.

With the transfluid t control software the tablet PC becomes a digital isometry paper for precise 3-D views.

Digital drawing with t control
The easiest method is the use of a digital drawing tablet. transfluid makes available the appropriate programs for creating isometry drawings with its high-performance software "t control", as Gerd N?ker explains: "A customary tablet PC can be used. Our transfluid software enables 3-D drawings of the tubes by using a pen on digital isometry paper. An operator can measure the desired geometry directly at the object with the drawing tablet, draw and send it via e-mail to the bending centre." Additionally, there is the possibility to equip the drawn geometry with flanges, welded connections or endforming. By this, not only a simple bending geometry can be sent to the bending centre but a completely ready-to-install component can be pre-finished. For an easy inspection if the drawn geometry matches the desired component a 3-D view of the tube is available. With its help the drawer can identify elementary mistakes at first glance.

For bending freedom transfluid unites it software t control effectively and economically with its advanced bending technology.

Flexibility, freedom with precise measuring arm
An optional procedure that transfluid is providing for the safe measurement of a tube (for example, for reproduction) is a special measuring arm with appropriate software. transfluid uses measuring arms equipped with absolute rotary encoders. They are deployed at the object or, for example, attached with magnet feet and provide the advantage that they do not have to be referenced. With these measuring systems the tubes can be acquired by simple scanning of the cylinders bAir Jordan VI 6 Shoes
