Summary

The a81nx is a 4-axis horizontal machining center designed for large-part machining applications requiring both high torque and high spindle speed operations. It delivers expanded work envelope, heavy-duty spindle options, and increased tool capacity for demanding metalworking tasks such as roughing of iron castings and aerospace hard metals. Differentiating features include dual spindle offerings, robust B-axis table support, and ergonomically enhanced tool loading systems.

Key Capabilities

• 4-axis machining with continuous 360° B-axis rotary table for complex part geometry
• Choice of high torque 8,000 RPM spindle or 10,000 RPM standard spindle for material versatility
• Large work envelope accommodates parts up to 1,000 mm diameter x 1,300 mm height
• Heavy tooling support with increased tool length, diameter, and weight capacities
• Fast tool change with servo-driven automatic tool changer and integrated tool loading station
