This Extrema bridge cutter is designed and constructed according to the tested Sassomeccanica technology. Extrema combines reliability and the performance with the perfection of its shape, harks the combination of steel with plastic reinforced by fiberglass. The bridge is large sized and is treated with anti-vibration and soundproofing expanded materials. Both the carriage forward movement and the bridge movement systems are controlled by speed control motors, which ensure smooth and accurate movements. Dual chromium-plated built-up lubes guide the disk upward and downward movements, whose stroke is electronically controlled. A large bearing allows the rotation of the bench, whose lock is controlled by a pneumatic servo control.
