LARGE COMPLEX PART MACHINING OF TOUGH ALLOYS
The 360,000-position full-contouring rotary 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.
Eight spindle options include 6000 and 8000 rpm/46 kW (61.6 hp) tilt-spindles with +90/-120 deg A-axis travel; a 10,000 rpm/46 kW (62 hp) spindle; high-speed 24,000 rpm spindle; T-Rex high-torque 2600 Nm/80 kW (1918 ft lb) spindle and two live spindles (110 or 130 mm diameter). The high-torque T-Rex spindle is ideal 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, the exclusive Z-axis thermal compensation system dynamically offsets spindle growth to maintain correct axial position regardless of spindle temperature.
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.
The HMC 1600 is available with optional MQC (Minimum Quantity Cryogenics) and MQL (Minimum Quantity Lubrication). Other recent aerospace machine introductions include the FTR AutoDrill for processing large, high-value aerostructures; large-part 5-axis gantry mills; and vertical precision mill and trim (PMT) systems. The highly configurable PMT is engineered for high traverse and acc/dec rates. Its patent-pending vacuum system makes it ideal for high-velocity milling, trimming and drilling of post-cure cutouts, wood, foam, composite, aluminum and titanium structures. www.mag-ias.com
