High specification band saw ADVANCEMENTS in automation and integration of sawing techniques within companies’ value added chain require continuous increase in performance, very economic systems and customised complete solutions. At the same time we are responsible for our environment and committed to use energy and resource saving technologies. MEBAe- cut meets these requirements without compromise. MEBAe-cut is equipped with a newly electric material clamp. The material is clamped in 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 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. MEBA Sawing Solutions – Germany Email: moser@meba-saw.de

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. MEBAe-cut machines also score on the concerns below compared to hydraulic based systems: lower maintenance/running costs; no need to replace hydraulic oils, filters, etc; machine/blade performance due to increased hydraulic temperature; and hydraulic leaks, which can be a major concern in the maintenance of cutting fluids and operator safety. Noise reduction is another positive that the MEBAe-cut has over rivals. 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. Almost ten years ago MEBA was the first industrial manufacturer to integrate electrical systems into its machines with the linear ball screw feeds. The new high-performance-band saw is again a pioneer in the industry, dispensing with the use of hydraulic systems entirely.
