USED MAZAK NEXUS 6800-II – 2012

The MAZAK NEXUS 6800-II is a heavy-duty horizontal machining center designed for high-volume production, large-part machining, and demanding metal-cutting applications. The 2012 NEXUS 6800-II combines a rigid cast-iron structure, powerful CAT 50 spindle, advanced pallet automation, and the MAZATROL Matrix Nexus CNC control to deliver exceptional productivity, accuracy, and reliability in modern manufacturing environments. The machine is engineered to maximize spindle utilization while minimizing setup times and non-cutting operations.

Built around Mazak’s proven horizontal machining platform, the NEXUS 6800-II utilizes a horizontal spindle orientation that naturally improves chip evacuation. Chips fall away from the cutting zone, reducing recutting, improving surface finishes, extending tool life, and supporting longer unattended machining cycles. The machine’s robust construction and thermal stability make it particularly effective for machining large steel, cast iron, stainless steel, and alloy components.

The machine features a dual-pallet changer system that allows workpiece loading and unloading while machining continues on the active pallet. Many installations are integrated into Mazak Palletech manufacturing systems for lights-out production and highly automated manufacturing environments.

The 2012 MAZAK NEXUS 6800-II is widely used across aerospace, defense, energy, mining, oil and gas, heavy equipment, transportation, and precision contract manufacturing industries where high material removal rates and exceptional reliability are critical.
