The 2007 SNK IKEGAI NB130PE3.5 is a heavy-duty CNC horizontal boring mill built for large-scale precision machining of complex workpieces. Equipped with a 130mm (5.12-inch) spindle bore and 50 Taper spindle interface, this machine delivers the rigidity and power needed for demanding boring, milling, drilling, and tapping operations on oversized components. Its generous envelope includes 138 inches of X-travel, 98 inches of Y-travel, 63 inches of Z-travel, and 25.5 inches of W-axis quill extension, giving operators exceptional reach across large parts without repositioning. The 35 HP spindle motor drives speeds up to 2,500 RPM, providing the torque and surface speed flexibility required for both roughing and finishing cuts across a wide range of materials. The integrated NC rotary table features 0.001-degree closed-loop indexing with a 90-degree locating pin, enabling precise multi-face machining in a single setup. Rapid traverse rates of 394 IPM across all three linear axes ensure minimal non-cutting time between operations, while built-in coil chip conveyors on the X and Z axes keep the work zone clear during extended production runs. Additional features include a spindle orientation function, oil temperature regulation in the spindle head, and halogen work lighting.
The NB130PE3.5 represents a significant step up from earlier SNK IKEGAI horizontal boring mills such as the NB130P and NB130PE series. Where the earlier NB130P models offered conventional table indexing and more limited axis travels, the NB130PE3.5 introduces full NC rotary table control with 0.001-degree resolution, a longer W-axis quill stroke of 25.5 inches for deeper reach into complex parts, and improved rapid traverse rates for faster cycle times. The PE3.5 designation signals enhanced servo performance and thermal management over the base PE models, including the integrated oil temperature regulator that maintains spindle thermal stability during extended heavy cuts. For shops currently running older floor-type boring mills or smaller-spindle HBMs and looking to consolidate setups on large fabrications, castings, or weldments, the NB130PE3.5 offers the combination of reach, rigidity, and precision that replaces multiple operations on lesser machines.
