MAG’s modular HMC 1250/1600 Series is engineered for high precision, high productivity machining of large aerospace, power generation, pump, valve, and off-road equipment parts. It now includes eight spindle options to suit special-purpose or general machining requirements.
The new 6000 and 8000 rpm/46-kW (61.6-hp) tilt-spindles – with +90/-120 degree A axis travel joins an all-around 10,000 rpm/ 46-kW (62-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 is especially suited for hard-metal 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 tools. Standard on the live spindle, MAG’s exclusive Z-axis thermal compensation software dynamically offsets spindle growth to maintain tight tolerances.
Designed for application flexibility, the HMC 1250/1600 offers maximum 3000 mm (118 in.) work zone swing, and 15,000 kg (33,000 lb) pallet load capacity. Major machine components, including the X bed, Z bed and column, are cast ductile iron, with pallets up to 1600 x 2000 mm, headstock and rotary table housings of gray cast iron. Modular design provides a range of machine travels, 60- to 300-tool magazines and two control choices.
Powerful and agile, the new five axis HMC offers 56 to 100 kW (75 to 133 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 up to 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 is pre-engineered to provide a clean machining environment and includes a doorway for operator access with walkway/platform inside.
