Nicolas Correa FOCO

The FOCO is Correa's portal-type boring/milling platform, where a bridge structure travels over a floor-mounted workpiece. This contrasts with Correa's floor-type boring mills (like the NORMA and FOX) where the column travels on floor rails but the spindle is directly carried by the column without a bridge. The FOCO's portal configuration provides a more rigid, enclosed machining environment for large die and mold workpieces, while the floor-type designs offer longer X-axis travel for very extended parts.

The 130 mm spindle is appropriate for most general-purpose boring, milling, and drilling operations on medium-to-large castings and mold bases where bore diameters are typically under 200 mm. The 160 mm spindle provides additional rigidity and torque for very heavy rough boring passes in steel and cast iron, deep-bore operations, and applications where bore diameters frequently exceed 200 mm. The 160 mm option also supports larger boring bar extensions for deep features. If in doubt, Nicolas Correa applications engineers can recommend based on your specific workpiece program.

Nicolas Correa's ram damping system incorporates passive and active vibration damping elements in the ram structure that carries the boring spindle. During heavy boring cycles, cutting forces generate periodic vibration in the ram that can cause chatter, reducing bore quality and tool life. The damping system absorbs this vibrational energy, particularly at the natural frequencies of the ram structure, enabling more aggressive boring parameters without quality degradation. The system is passive (no operator input required) and operates continuously during machining.

Yes. While the FOCO's 130/160 mm spindle and low-RPM torque curve is optimized for steel and cast iron heavy machining, the machine can perform aluminum boring and milling operations. At 2,500 RPM maximum, the FOCO does not match the surface speeds of a high-speed machining center for aluminum finish work, but for large aluminum structural workpieces requiring precision boring and facing rather than high-speed pocket milling, the FOCO is fully capable.

Nicolas Correa S.A. is headquartered in Burgos, in the Castile and Leon region of northern Spain. Founded in 1947, the company has been producing large-format milling and boring machines for over 75 years. Correa is widely regarded as one of Spain's most important machine tool manufacturers and has exported machines to customers in over 50 countries. The company produces a range of floor-type, table-type, and portal boring/milling centers under the CORREA brand.
