The DN Solutions HM 1250 is a large-frame CNC horizontal machining center engineered for manufacturers requiring exceptional rigidity, massive cutting power, and superior machining performance on oversized workpieces. Built with a heavy-duty one-piece cast iron structure and precision box guideways, the HM 1250 delivers outstanding vibration damping, excellent thermal stability, and long-term machining accuracy during demanding roughing and finishing operations. Equipped with a high-torque gearbox-driven spindle, shuttle-type automatic pallet changer (APC), servo-driven automatic tool changer (ATC), and advanced spindle cooling technology, the HM 1250 is designed for continuous production of large, high-value components across the aerospace, energy, mining, heavy equipment, oil & gas, shipbuilding, and industrial machinery industries.
The machine provides 83 inches (2,100 mm) of X-axis travel, 59 inches (1,500 mm) of Y-axis travel, and 59 inches (1,500 mm) of Z-axis travel, offering an exceptionally large machining envelope for oversized components. It features a 49 × 49 inch (1,250 × 1,250 mm) twin-pallet system capable of supporting workpieces weighing up to 6,614 lbs (3,000 kg). The standard 6,000 RPM ISO 50 gearbox-driven spindle produces 35 HP (26 kW), while an optional 8,000 RPM spindle increases output to 50 HP (37 kW). Maximum spindle torque reaches 1,467 ft-lb (1,989 Nm), while the optional high-torque spindle delivers up to 2,719 ft-lb (3,687 Nm) for extreme heavy-duty machining applications. Rapid traverse rates of 945 IPM (24 m/min) minimize positioning time, and the standard 60-tool automatic tool changer can be expanded for automated production systems. The HM 1250 is ideal for machining large gearbox housings, wind turbine components, heavy castings, mining equipment, aerospace structures, and industrial machine bases requiring maximum rigidity and high material removal rates.

DN SOLUTIONS HM 1250 – AXIS TRAVELS / WORK ENVELOPE
Purchasing a used DN Solutions HM 1250 allows manufacturers to acquire one of the largest and most capable heavy-duty horizontal machining centers available while significantly reducing capital investment. The machine’s rigid box guideway construction and gearbox-driven spindle provide outstanding cutting stability during aggressive roughing and heavy-duty machining operations. Its large pallet capacity and oversized work envelope make it ideal for machining massive castings, fabricated structures, and precision components that exceed the capabilities of conventional horizontal machining centers.
The shuttle-type automatic pallet changer enables continuous production by allowing operators to load and unload workpieces while machining continues on the second pallet, maximizing spindle utilization. Many used HM 1250 machines are equipped with valuable factory-installed options such as high-pressure through-spindle coolant, Renishaw probing systems, expanded tool magazines, automatic tool measurement, and automation interfaces. The reliable Fanuc CNC control provides worldwide support, easy programming, and dependable long-term operation.
HOW MUCH DOES A USED DN SOLUTIONS HM 1250 COST?
The price of a used DN Solutions HM 1250 depends on the year of manufacture, spindle hours, machine condition, maintenance history, tooling packages, CNC configuration, and installed factory options.
Most used DN Solutions HM 1250 machines typically sell between $400,000 and $950,000, depending on machine age, spindle configuration, installed automation, and overall condition. Machines equipped with the optional 8,000 RPM spindle, expanded tool magazines, high-pressure through-spindle coolant, probing systems, and documented maintenance histories generally command premium resale values.
Before purchasing a used HM 1250, buyers should inspect spindle condition, box guideway wear, pallet changer operation, B-axis indexing accuracy, lubrication systems, automatic tool changer performance, coolant systems, and machine geometry. Transportation, rigging, installation, electrical work, tooling, and preventive maintenance should also be considered when budgeting. Even after these costs, purchasing a used HM 1250 remains significantly more economical than buying a comparable new machine.
