FIVES GIDDINGS & LEWIS HMC 1250 HORIZONTAL MACHINING CENTER

Technical Description

The Fives Giddings & Lewis HMC 1250 is a precision horizontal machining center engineered for versatile metal and composite part production. This four-axis system features a robust 49.21" × 49.21" pallet with 11,000 lbs maximum workpiece capacity and incorporates an automatic dual-pallet shuttle for enhanced productivity. The machine delivers X-axis travel of 82.7" (expandable to 106.3"), Y-axis travel of 59.1" (up to 70.9"), and Z-axis travel of 68.9", with rapid traverse rates reaching 1,575 ipm across all axes. The horizontal spindle operates at 24,000 rpm maximum with 80.5 hp (30-minute rating), providing substantial cutting power for demanding applications. A 90-position automatic tool changer ensures rapid tool indexing and minimized cycle times. The machine incorporates Siemens or Fanuc CNC controls with advanced monitoring capabilities for spindle load management and thermal compensation. Optional five-axis capability expands machining flexibility, and seven headstock configurations—including high-torque, tilt, high-speed, live spindle, and dual-spindle variants—accommodate diverse production requirements. The rigid box-in-box structure with one-piece cast bed and column provides exceptional stiffness and damping for precision accuracy. Standard features include through-spindle coolant delivery (1015 psi), Renishaw touch probe integration, and tool breakage monitoring. Fast traverse rates of 25 m/min combined with modular design architecture deliver reduced cycle times while maintaining the precision and rigidity Giddings & Lewis machines are renowned for in aerospace, defense, and heavy-duty industrial machining applications.
