Circular saw for inline cutting INTERNATIONAL Dutch-based saw blade expert Kinkelder has developed a special circular saw for the inline cutting of ID-scarfed ERW-tubes. The new ScarfMaster breaks the weld bead effectively during cut-off. When compared to ‘normal’ saw blades, ScarfMaster outlasts other products by a factor two to three times. scarfing the internal weld bead, often about 6mm thick solid steel, remains inside the tube. During cut-off this inside wire is caught by the saw, causing a huge peak load usually on one saw tooth. This can easily lead to tooth breakage. We started developing a new saw in 2010, which resulted in the conception of ScarfMaster.”

which give the combination tooth/ body very high stability and fracture resistance. The ScarfMaster was officially introduced at the Tube trade fair in Düsseldorf this year. “Not only is the blade life of the new ScarfMaster considerably longer, it can also cut 50 per cent faster,” emphasised Mr Molenaar. “Due to this, line speed can be significantly increased. Also, the line does not have to be shut down as often to change the saw blades, which means better uptime. In all regards, the new ScarfMaster saws improve productivity of the tube line and this automatically reduces cost of production per tube length. There is already a rapidly growing number of enthusiastic tube manufacturers in the USA, Spain, Romania and Poland who successfully use ScarfMaster saw blades for their tube lines.” ScarfMaster saw blades are available in diameters of 400, 450, 500, 560 and 600mm destined for the production of tubes in the diameter range of 2.5" to 7" (63.5mm to 168mm).

ScarfMaster is a carbide tipped saw blade featuring a very specific tooth- geometry, while tips themselves are made of a highly shock resistant type of carbide. The teeth are supported by a saw body with extra strong shoulders,

“An important customer that produces welded ERW tubes for the oil and gas industry asked us to develop a better solution for their cut-off application,” said Leo Molenaar, application engineer at Kinkelder. “The point is that after ID

New software platform for all data and processes around manufacturing of bent parts

or the addition of new applications around bending like end forming or assembly management – the AICON BendingStudio offers a platform for the optimised integration of all data and processes for bent parts. The software platform BendingStudio was presented in public at Tube 2012 in Düsseldorf. Visitors received detailed information on AICON’s stand in hall 7a, booth B02. The software will be ready for use in a production environment in the 4 th quarter of 2012. AICON 3D Systems GmbH – Germany Fax: +49 5 3158 00060 Email: info@aicon.de Website: www.aicon3d.de

document all changes in the different process steps. BendingStudio optimises the data handling for every production step and offers the right solution for every user. At the same time BendingStudio has a simple and clearly structured handling concept. Many small tools ease the daily work in all areas of bent part manufacturing. For example, it is possible to construct bend data from centre line data. Or, before applying corrections, the effects of a modified bending program can be simulated. The data concept of BendingStudio is already prepared for future applications. Be it if the connection to different measurement systems, the integration of new manufacturing technologies

THE newly developed software platform BendingStudio was introduced by Aicon at this year’s Tube Düsseldorf show. BendingStudio connects all data and processes around production of bent parts: from production process planning to manufacturing to quality control. It is the only tool to meet and combine these requirements with emphasis on metrological processes. Especially in combination with the AICON TubeInspect systems, BendingStudio offers efficient and customer-orientated solutions for all applications around manufacturing of bent parts. The software platform combines all data belonging to a certain part and allows manufacturers to monitor, quantify, visualise and
