NIIGATA SPN-50 HORIZONTAL MACHINING CENTER

Technical Description

The Niigata SPN-50 is a high-performance horizontal machining center featuring equal X, Y, and Z-axis travels of 29.5 inches (749.3 mm) each, providing a balanced 3-axis working envelope. It is powered by a robust 40 horsepower spindle motor capable of speeds up to 12,000 RPM, with a CAT 50 spindle taper ensuring rigidity and compatibility with a wide range of tooling. The machining center includes a highly efficient tool changer holding up to 178 tools, supporting continuous production and reduced downtime. It utilizes twin pallets measuring 19.7 inches by 19.7 inches (500 mm x 500 mm) with a maximum pallet load capacity of 1,320 lbs, facilitating rapid and precise pallet changes typically within 6-7.5 seconds. The machine structure incorporates a heavy-duty boxway design for superior rigidity and stability during high-speed machining, enabling heavy-duty, high-accuracy production. Controlled by Fanuc 16M CNC control, the unit offers rapid traverse rates up to approximately 1,575 to 1,969 IPM in all axes and a feed rate of up to 1,181 IPM, boosting productivity. The spindle design includes a short taper to maintain stable cutting performance at high speeds. Overall machine dimensions are approximately 196" x 96" x 108" with a weight nearing 27,000 lbs, reflecting its industrial-grade construction suitable for demanding horizontal milling operations. Additional features include a spindle head-to-table clearance from 5.9" to 35.4", supporting a broad range of workpiece sizes and tooling setups .
