Doosan HM1250 HORIZONTAL MACHINING CENTER

The 2017 Doosan HM1250 is a heavy-duty horizontal machining center engineered for large-scale precision manufacturing across aerospace, automotive, and heavy equipment sectors. This machine features a robust box-guideway structure with high-rigidity axis design, incorporating preloaded ballscrews coupled to absolute-type servo motors to minimize thermal error and optimize accuracy. The system operates with a maximum spindle speed of 6000 RPM and delivers a 35 HP spindle motor, providing exceptional cutting capability for processing aluminum, steel, and titanium materials. Equipped with a Fanuc 31i-Model B CNC control system, the machine offers precise motion control across its generous work envelope of 82.7" (2100mm) X-axis travel, 59.1" (1500mm) Y-axis travel, and 59.1" (1500mm) Z-axis travel. The dual automatic pallet changer system features 49.2" x 49.2" pallet dimensions with 1-degree indexing capability, supporting workpieces up to 13,200 lbs, enabling efficient multi-part production without manual intervention. The machine incorporates a 90-position automatic tool changer with through-spindle coolant delivery at 1.5kW and 2.0 MPa pressure, ensuring optimal cooling during aggressive cutting operations. Rapid traverse rates reach 944.88 IPM on X/Y/Z axes, while cutting feed rates achieve 472.44 IPM, minimizing non-cutting time and maximizing productivity. Additional features include a full chip and splash enclosure with integrated chip conveyor, MPG handle control, and AICC200 block compatibility, making this HM1250 an ideal solution for complex, high-volume component manufacturing requiring precision, reliability, and operational efficiency.
