machine control. For example, thin- walled tubes can be clamped safely. In combination with the proven MEBA saw feed system, the MEBA material in-feed system and the backlash- free guide elements, MEBAe-cut is claimed to be unrivalled in precision and reliability. The saw feed works via servo-controlled lead ball screw spindle with automatically controlled cutting pressure and feed control. The band saw control also includes a two-handed operating system for rapid vertical movement. On automatic machines a new control system reduces the required remainingmaterial clamping section to 110mm. The material in-feed system is also controlled by electric servos and lead ball screw spindles. The machine has automatic material height detection and positioning of the adjustable blade guide arm movable via the clamping vice-jaw. These factors ensure a high degree of flexibility. The control panel and chip conveyer can be located on the driven wheel or tension wheel side of the machine. The youngest member of the MEBA family also boasts a compact design. Its new CNC control is based on Windows CE with touch-sensitive panel. MEBAe-cut is available in three models 400, 500 and 600, and is available as a semi-automatic machine or a 90° fully automatic machine. All models are made for high productivity and for long-term and continuous use in single- and multiple-shift operation. MEBA Sawing Solutions – Germany Website: www.meba-saw.de

THE MEBAe-cut band saw operates without the need of a hydraulic motor, instead using electrical drives resulting in a clean cut without compromise. Advancements in automation and integration of sawing techniques within companies’ value added chain require a continuous increase in performance, economic systems and customised complete solutions. At the same time environmental factors and energy use are more important than ever. MEBAe-cut meets these requirements. All the drives on MEBAe-cut models are powered by soft start motors, eliminating voltage spikes. Electrical axles are moved with high precision and accuracy, resulting in efficient power consumption, improving cutting accuracy and increasing the life of the saw blade. Electrical driven systems have a significantly lower power demand when compared to a hydraulic- based system. For example, material clamping: hydraulic clamping requires permanent pressure, consuming energy during a cutting cycle. Electric clamps only require energy for the vice movement (clamping and releasing), not during the cutting cycle. At the same time, there is no danger of leaks when using electrical clamps. Compared to hydraulic-based systems, MEBAe-cut machines also have lower maintenance and running costs, there is no need to replace hydraulic oils and filters, the machine/ blade performance is improved due to increased hydraulic temperature, and

hydraulic leaks, which can be a major concern in the maintenance of cutting fluids and operator safety, are no longer a problem. Noise reduction is another positive for the MEBAe-cut. The only noise generated is the sound of the blade cutting the material resulting in a much quieter cut, which can be a major consideration when purchasing new equipment due to health and safety restrictions on noise levels within the working environment. Hydraulic-based machines have additional noise produced by the hydraulic pumps and motors, even if the machine is not working. MEBA was the first industrial manufacturer to integrate electrical systems into its machines with the linear ball screw feeds. MEBAe-cut high- performance band saw has again been a pioneer in the industry, dispensing with the use of hydraulic systems entirely. The MEBAe-cut is equipped with a newly electric material clamp. The material is clamped in the main and in- feed vice by a servo-controlled spindle drive. The clamping pressure can be adjusted individually for each application and can be pre-selected via the
