NIIGATA SPN50-HO HORIZONTAL MACHINING CENTER

Technical Description

The 2001 Niigata SPN50-HO is a robust horizontal machining center featuring a CAT 50 spindle taper driven by a 30 HP motor, capable of a maximum spindle speed of 12,000 RPM. It offers ample work envelope with travel axes measuring 30 inches (X), 30 inches (Y), and 26 inches (Z), allowing machining of sizable components. The machine supports two pallets sized 19.7 x 19.7 inches, each with a load capacity of up to 2,200 lbs, facilitating efficient workpiece changes. Tool management is enhanced by a 60-tool automatic tool changer accommodating tools up to 4.92 inches in diameter, 17.72 inches in length, and 44 lbs in weight, optimizing production flexibility. Rapid traverse rates reach 1,417 inches per minute across all axes, matching the maximum cutting feed rate for high throughput. Control is managed through a Fanuc 16iM CNC system, integrating full 4th axis capabilities for complex geometries. Coolant-through-spindle and chip conveyor systems improve machining quality and operational cleanliness. The machine weighs 33,000 lbs and requires 220V, 3-phase power. Its durable construction ensures precision and stability in heavy-duty applications, making it suitable for production environments requiring high rigidity and repeatability. Overall, the SPN50-HO balances cutting performance, automation, and versatility for advanced horizontal machining tasks.
