Innovations in tube cutting
CYTUBE T5 version .
CYTUBE is CY-Laser ’ s fibre-laser system designed for cutting tubes with different profiles ( round , rectangular , square or other standard profiles with a diameter from a minimum of 15mm to a maximum of 225mm ).
“ In its new version , CYTUBE has become a modular system that allows customer to solve issues related to available space , avoiding the need to choose a customised machine with particularly high costs . The choice to equip CYT5 and CYT9 , the two versions of CYTUBE , with a modular structure means , in fact , reducing costs not only for the customer but also for the manufacturer , while maintaining high quality and reliability ,” said the Italian manufacturer .
Its main features include automatic scrap conveyor ; automatic setting of the clamps with adjustment of the jaws for reductions in production change-over times ; adaptive grip of the tube with automatic adjustment for more effective closure on materials of different thicknesses and more .
“ The heart of CYTUBE is the process cell , while tube handling is its key automation feature since it allows users to manipulate the tube in the process cell by guiding it with the movements necessary to complete all planned processes ,” confirmed the Italian laser-cutting specialist . n

Pickling products for weld seam cleaning
The new Zundex product range is designed to treat metal surfaces after heat exposure ( i . e . after welding ). The range consists of three products for copper , copper alloys , nickel , iron and steel as well as for stainless and acid-resistant stainless steels of all kinds .
“ In many work processes that require heat treatment , changes to the material surface inevitably occur . These are mainly oxidation phenomena that lead to undesired discolouration of the metal . Welders , for example , are familiar with the problem of tarnish which can hardly be avoided . With our Zundex products , these oxides can be removed quickly and easily ,” explained Markus Geßner , Marketing and Sales Manager , Emil Otto GmbH .
The same applies to surface discolourations that occur when using saw blades and similar , high-speed machining tools . “ Whenever the metal is exposed to high temperatures , these changes can occur . That is why they are also known as burn marks . Zundex pickling products provide a quick chemical remedy . Their active ingredients react intensively with all metal oxides . This dissolves the oxides so that they can be easily removed afterwards ,” Geßner continued .
The new pickling products are free of hydrochloric , sulphuric and nitric acid . They do not contain hydrofluoric acid or any hydrofluoric acid salts . Special wetting agent additives cause a rapid and uniform reaction on the surfaces to be treated .
“ When using our Zundex products , a somewhat slower reaction is sometimes observed in comparison to pickling mixtures of more aggressive , and therefore often highly toxic , mineral acids ,” Geßner cautioned . However , he added , this is offset by the benefits of the milder Emil Otto pickling agents , which do not emit free chlorine or nitrous gases .
If surfaces to be treated are not only discoloured by oxidation , but also display other impurities ( such as burnt oil or resin residues , coarse welding slag or other heavy dirt ) these must first be removed mechanically . The Zundex preparation can then be applied by brush or similar .
For the treatment of already mounted , sloping , vertical or overhead surfaces , Emil Otto also offers a Zundex paste . As soon as the oxide layers have been chemically transformed , they can be removed by brushing or wiping . For particularly heavy contamination , treatment with Zundex can be repeated , said the manufacturer . n
