Fully automatic CNC machine SIMEC from Italy offers a fully automatic CNC machine designed to utilise DMO5 circular saw blades and all their derivatives. The machine can cut to any

pre-programmed angle of ±60° and has the ability to cut intersecting angles on the end of a wide selection of material types. With a choice of three loaders the machine is suited to load and feed both symmetrical and asymmetrical profiles. The CNC control uses a sophisticated program that is able to process all the data and then select and optimise this to give the greatest efficiency with the minimum of waste. Particular attention has been paid to reducing the scrap end of the material so that this can be as little as 20mm. The material in-feeding is servo controlled, as is the head rotation; with this the tolerances of the cut pieces are maintained to a high accuracy making this suitable for robotic welding systems. The saw can be linked to a deburring machine or multi-discharge feature (the standard version has three-position discharge).

Cutting heavy ID scarf GEBRÜDER Lennartz GmbH & Co KG, from Remscheid, Germany, a manufacturer and supplier of carbide-tipped circular saw blades for the ferrous and non-ferrous industry, has launched another product in the ECOmax range. The newly developed ECOmax – Scarf circular saw blade is customised for cutting tubes and profiles with heavy ID scarf on flying cut-off units. Previously, conventional blades were heavily damaged after only a few cuts because they cut the high strength weld bead inside the bottom of the tube. The service life of the blades was poor and the cost per cut was high, resulting in a cutting application that was not economical. Because of its special tooth form and cutting geometry, and in combination with a new proprietary coating, the ECOmax – Scarf saw blade is suitable for this application. The new design works successfully on single-head machines as well as on twin saws with the simultaneous operation of two saw blades. Successful trials and ongoing production usage together with target customers and machine manufacturers have shown that the ECOmax – Scarf blades achieve up to 7m 2 of material removal on welded tubes with wall thickness up to 14mm. Further wear life tests and enhancements are planned to improve the blades’ performance.
