Process reliability in tube marking REA JET exhibited its variable systems for inner and outer marking of pipe at the recent Tube Düsseldorf show in Germany. These solutions meet the demands for marking with inks, laser and paints. In particular, the marking with DataMatrix codes lays the foundations for a rapid identification and traceability of products and thus the basis for the optimisation of all processes and procedures. outer surfaces of pipes, the DOD is also suitable for inner marking of pipes starting from 200mm inner diameter. To do that, a compact 32 nozzle print head mounted to a special mounting device is driven into the tube. The contact-free marking takes place during the rotation of the tube. The time-consuming and error-prone method of using stencils is no longer required. For high-resolution, contact-free marking of metal or plastic surfaces REA has the ink jet printer REA JET HR in its range. The readability of the high resolution print image is a great advantage especially for small pipe diameters. The available inks convince by excellent adhesion and fast drying time.

For the first time REA introduces the brand-new REA JET FL fibre laser for captive marking of metal, plastics and other materials. The high beam quality and energy density of the laser beam ensures short marking times and excellent marking quality even with very fine marking content. The REA JET FL fibre laser is an option for the growing demand of direct part marking (DPM) of metal surfaces. REA Elektronik GmbH – Germany Email: rheil@rea.de Website: www.rea-jet.de

Also Spray Mark Technology solutions are presented for marking weld lines and coloured rings onto pipes as well as for longitudinal marking of wire cables. These markings support the identification, quality inspection and the correct installation of the respective products. Spray Mark Technology systems are also used to apply paint full-screen to prepare the pipe for inner tube marking. After that a REA JET CL CO 2 laser system removes the paint and leaves a legible and sharp-edged marking.

It presented its robust solutions for pipe manufacturers who need to mark their products to be traceable. REA JET shows steel tubes marked with DataMatrix codes. The REA JET Large Character Ink Jet DOD and Spray Mark Technology Systems process the data received from the production master computer and convert it in real-time into serialised in readable text and 2D codes. Each marking is unique and each tube is traceable as one of a kind. In addition to the marking of the

BEHL commissions groove dressing machine

300mm and 380mm. The machine is equipped with a measuring system which provides automatic stand and roll measurements. The rolls are machined at the front end of the stand; therefore any groove design can be produced. The technology from SMS Meer enables the edge radii to be dressed in one pass. The ceramic cutting tools in the holder system mean good milling conditions and short changing times can be achieved. The grooves are machined automatically in two passes with a high degree of precision. The whole process takes less than 30 minutes. Changes to the groove shape can be made easily by quickly re-programming the system. The machine is also linked to works databases and control systems, such the CARTA ® technology system (Computer Aided Rolling Technology Application) from SMS Meer, for example.

of its stretch reducing mill will be fitted with the latest roll pass technology in future. The groove dressing machine supplied by SMS Meer machines the grooves in the rolls fully automatically. The roll diameters to be machined are

BHARAT Heavy Electricals Limited (BHEL), based in New Delhi, India, has commissioned a new groove dressing machine of type KR I 30/38 CNC, supplied by SMS Meer. With the new machine and the push bench plant upgraded by SMS Meer, the roll stands
