Niigata SPN50 HORIZONTAL MACHINING CENTER

The 2000 Niigata SPN-50 is a heavy-duty horizontal machining center designed for precision component manufacturing and production work. This CNC machine features dual 19.65" x 19.65" pallets with a maximum load capacity of 1,320 lbs., enabling continuous production through pallet indexing. The machine delivers exceptional rigidity through its double box structure construction, supporting stable accuracy across extended production runs. The SPN-50 provides 29.52" X-axis travel, 29.52" Y-axis travel, and 32.28" Z-axis travel, accommodating mid-sized workpieces across multiple machining applications. The spindle assembly operates across a wide speed range from 50 to 15,000 RPM, powered by a robust 40 HP motor, enabling both heavy roughing operations and precision finishing work. The CAT 50 spindle taper ensures compatibility with an extensive range of cutting tools, while the full 4th axis (B-axis) programmable indexing capability allows for multi-sided component machining without manual repositioning. The 60-position automatic tool changer facilitates rapid tool changes and extended unattended operation cycles. With a rapid traverse rate of 2,362 IPM across all axes and cutting feed rates from 0.04 to 1.575 IPM, the machine optimizes both cycle time and surface finish quality. The advanced Fanuc 61iMB CNC control system provides sophisticated programming capabilities, real-time diagnostics, and seamless integration with modern manufacturing systems. Operating on 400V/3-phase/60Hz electrical service, this machine represents an excellent solution for job shops and manufacturing facilities requiring versatile, high-precision horizontal machining capabilities with extended tool magazine capacity and rapid pallet exchange functionality.
