A new angle on HMC spindles: full Tilt precision and productivity for heavy 5-axis cutting on large aerospace and energy parts
MAG adds 180,000-position A-axis tilt spindle to HMC Series headstock selections, high-torque 2600 Nm spindle option handles Ti cutting with ease
November 2009 - MAG continues to follow "voice of the customer" input for the design of its modular HMC 1250 Series with a new 180,000-position A-axis tilt spindle for 5-axis horizontal machining on large parts. 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 (1918 ft lb) spindle and two live spindles (110 or 130 mm diameter) as headstock options. The high-torque, 80 kW, spindle 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. 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, in addition to five spindle options, plus tilt capability. That application flexibility combines with maximum 3000 mm (118 in) work zone swing range, 2050 mm (81 in) work height capacity and 7000 kg (15,400 lb) work load.
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. Productivity is enhanced with 40 m/min (1575 ipm) rapid traverse/feed rate and 15 sec tool change (for up to 35 kg tools) to maximize in-cut productivity.
A standard 360,000 position contouring table enables precision 4-axis machining of a variety of part geometries. The hydrostatic table provides a rigid machine platform, while a rugged worm gear drive with clamp securely holds axis position.
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 higher rapid traverse and acc/dec rates with double the load capacity and nearly 10 times the wear life of ball-type ways.
