Sawing machine for cutting steel pipes in layers

decreasing vibrations have different dimensions, and this will give a smooth and straight cutting surface and a longer tool life. Extra cooling of the saw blades has been installed, to allow hot tubes up to 200°C

LAZZARI has improved the design and technical features of its high-productivity sawing machines in order to meet requirements for increased performance and lower cost-per-cut. Components of the TL series sawing machines, such as the machine bed and structure to resist high loads, have been redesigned, and the clamping system to clamp in front of and behind the saw blade has been renewed. The controlled position and pressure eliminate the vibration of the tubes during the cutting operation. The heavy-duty guides for the sawing head ensure maximum stiffness, and the oversized dimensioned gearbox features a special system to automatically compensate for backlash. The dumping devices for giving guidance to the saw blade and for

layer, avoiding crossed over pipes and making the layer itself more stable. The Lazzari operation control is flexible and meets the specific requirements of the customer, such as error diagnostics, visualisation of the actual moving cycle of the machine on screen, cutting parameters, blade recording and cutting optimisation, and tele-maintenance.

and more to be processed. By increasing the saw blade diameter to 2,400mm it is now possible to have a larger width of layer than usual, and consequently the output will be increased. Sawing tools with a reduced cutting width have been developed to produce fewer chips and reduce energy consumption. In addition to a short cut-off time, the machines produce a sellable cut with nearly no burr. The additional external clamping devices ensure perfect clamping of the tube
