ROBUSTNESS “Today´s investment, tomorrow´s saving” Generously sized and properly ribbed structural parts, strong milling heads, machines in perfect geometry… have always been the distinctive features of NICOLÁS CORREA since its foundation in 1947. We are convinced Robustness is a good bet for our customers, a sensible investment that will result in the following benefits/values: In NICOLÁS CORREA, we extend the concept of robustness to the whole production process of the machine, always choosing technical solutions of the highest quality. For this reason, we offer as standard 5 year...

L-shaped guide system: • Greater rigidity and stability during machining. • Greater geometrical precision. • Less ram droop effect. What makes the difference in the NORMA? 6 vertical movement sliders ensuring good machine behaviour The NORMA represents a new concept in fixed frame, lateral ram machine. Very sturdy thanks to structural elements with large sections together with an L-shaped ram guide system. A high precision thanks to the mechanical ram droop correction system. A flexible machine suitable for machining and finishing operations Traction bars to eliminate the angular error of...
