5-Axis Gantry Mill Raises the Bar For Heavy-Duty Manufacturing of Parts Up to 7.5m High
MAG adds a new dimension to its universal gantry mills with the new adjustable-rail U6 Series, providing a vertical W-axis to accommodate extremely tall parts. The U6 universal machining center is engineered to bring the lean machining revolution to large, high-value, complex-geometry parts, enabling 5-axis machining and contouring with automatically interchangeable heads to minimize machine downtime, part reorientations and set-ups.
The machine's robust construction makes it ideal for heavy, tough cuts in big parts of steel, titanium, crusty forgings or aluminum. Wide application versatility delivers greater throughput and processing efficiencies to "large part" manufacturers in aerospace, off-road and heavy equipment, energy, die-mold, marine and mining.
The U6 can be configured with a massive cross rail (Y-axis) up to 9 m (29.5 ft), while the adjustable W-axis optimizes machine stiffness and provides up to 5 m (16.4 ft) of vertical travel to complement the up to 2.5 m (8.2 ft) Z-axis ram. The combination of WZ- and Y-axes offers a height and width range up to 7.5 x 9 m (24.6 x 29.5 ft) to accommodate machining in the extreme limits of the work zone, or provide clearance to maneuver over extremely large workpieces. The heavy-duty Z-axis ram, with 650 x 750 mm (25.6 x 29.5 in) rectangular cross section, supports multiple head configurations and spindle power options, while linear feed rates up to 20 m/min (787 ipm) enable fast response in heavy cuts on hard metals. The U6 design allows the cross rail to be positioned close to the part for machining with minimal ram extension and maximum stiffness for extreme accuracy. As options, the U6 is offered with a choice of 1 m, 1.5 m, 2 m and 2.5 m rams for best fit to processing needs.
The U6 universal machining center, available in bridge-type and rail-type platforms, is adaptable to accommodate a wide range of part size and shape requirements. The U6B bridge-type gantry utilizes a stationary support and optional X-axis pallet shuttle system that moves the part to coordinates on precision linear guide ways with rack-and-pinion drives for smooth, precise movement at high thrust levels. Available with a broad range of table and pallet shuttle systems, the U6 bridge-type can be equipped for single or multi-pallet operation to maximize cutting time during part load/unload. The U6R rail-type offers unlimited X-axis travel, and is expandable to fit the application.
Standard module options include choice of Fanuc or Siemens controls, a bridge/moving table or rail/moving gantry platform, single or dual-spindles, automatic tool change, and automatic head change – making the U6 an ideal, customizable solution for large prismatic part manufacturers looking for heavy-duty manufacturing capacity.
