Cutting heavy ID scarf

GEBRÜDER Lennartz manufactures and supplies carbide- tipped circular saw blades for the ferrous and non-ferrous industry. The company’s new ECOmax Scarf circular saw blade is customised for cutting tubes and profiles with heavy ID scarf on flying cut-off units. Previously, conventional blades could be 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 high. 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 on single head machines as well as on twin saws with the simultaneous operation of two saw blades. Successful trials and on-going production usage, together with target customers and machine manufacturers, have shown the ECOmax Scarf blades achieve up to 7m² 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.
