MAG's modular HMC 1250/1600 Series will be exhibited at IMTS with a new 180,000-position A-axis tilt-spindle for 5-axis horizontal machining on large aerospace and energy parts.
The HMS1250/1600 Series now includes six spindle options to suit special-purpose or general machining requirements.
The new 6000 rpm/46-kW (61.6-hp) tilt-spindle joins an all-around 10,000 rpm/ 56-kW (75-hp) spindle, high-speed 24,000 rpm spindle, high-torque 2600 Nm/80-kW (1918 ft lb) spindle and two live spindles (110 or 130 mm diameter).
The high-torque spindle (also exhibited at IMTS) is especially suited for aerospace titanium cutting, while the live spindles extend W-axis reach by up to 800 mm (31.5 in), enabling deep cavity milling to high precision with shorter, more rigid tool lengths. Standard on the live spindle, MAG's exclusive Z-axis thermal compensation software dynamically offsets spindle growth to maintain tight tolerances.
The HMC 1250 Series is engineered for high-precision, high-productivity machining of large aerospace, power generation, pump, valve, and off-road equipment parts. Designed for extreme application flexibility, the machine offers maximum 3000 mm (118 in) work-zone swing, 2050 mm (81 in) work-height capacity and 7000 kg (15,400 lb) pallet load capacity. Major machine components, including the X-bed, Z-bed and column, are cast ductile iron, with 1250 x 1600 mm pallets, headstock and rotary table housings of gray cast iron. Modular design provides a range of machine travels, 60- to 120-tool magazines and two control choices.
Powerful and agile, the new HMC offers 56 to 80 kW (75 to 107 hp) spindle power, 35 kN (7870 lb) Z-axis thrust, and super-rigid, full-contouring hydrostatic rotary table. The 360,000-position contouring table provides a rigid work platform, while a rugged worm gear drive with clamp securely holds axis position. Rotary table positioning accuracy is 10 arc seconds, repeatable to 5 arc seconds. Positioning accuracy of the tilt-spindle is 4 arc seconds, repeatable to 2 arc seconds.
Meeting industry needs for tighter part tolerances and greater machining accuracies, the HMC Series comes standard with linear scale feedback in X, Y and Z axes, providing 8 micron (0.0003 in) positioning accuracy and 5 micron (0.0002 in) repeatability. Heavy-duty hardened and ground roller guide ways enable a rapid traverse rate of 40 m/min (1575 ipm) with high acc/dec rates, double the load capacity and nearly 10 times the wear life of ball-type ways. The full work zone enclosure on the machine is pre-engineered for mist collection and includes a doorway for operator access with walkway/platform inside.
