2022 Smart NX-7000 CNC 4-Axis Horizontal Machining Center

The Smart NX-7000 is a 4-axis horizontal machining center - built by Niigata Machine Tools of Japan - with a reputation for the rigidity and thermal stability that make horizontals the backbone of high-volume, multi-side production. This 2022 example delivers X/Y/Z travels of 39 x 37 x 41 in, a 12,000 RPM #50-taper spindle driven by a 40 HP motor, a full continuous 4th-axis rotary table, and a 24 x 24 in pallet, with a 64-tool automatic tool changer feeding the spindle. It runs a Fanuc 31i-M control and is equipped for production: a Renishaw OMP60 work probe, a Renishaw NC4S laser tool setter, 870 PSI through-spindle coolant, an overhead shower coolant system, linear scale feedback on the X, Y, and Z axes, a chip conveyor, and eight additional M-code outputs.

Compared with the smaller Smart NX-5000, the NX-7000 is the larger-envelope machine in the same Niigata-built NX horizontal line. Where the NX-5000 targets compact horizontal work, the NX-7000 steps up to a 24 in pallet and 39 x 37 x 41 in travels with a 64-tool magazine and a 40 HP, 12,000 RPM spindle - meaning bigger fixtures, heavier parts, and longer unattended tool lists without giving up the shared Fanuc control platform and Japanese-built rigidity. For a shop weighing a used horizontal, that translates into more usable work zone and tool capacity per setup, which is what turns a horizontal into a lights-out profit center.
