Overview
The OMAX 120X is OMAX Corporation's bridge-style large-format waterjet cutting system, featuring approximately 120 inches (3,048 mm) of X-axis travel and 60 inches (1,524 mm) of Y-axis travel for a total cutting envelope near 10 x 5 ft. Unlike OMAX's standard cantilever-gantry machines, the 120X uses a full bridge gantry supported on both sides of the tank, providing significantly greater rigidity on the larger cutting envelope and eliminating the gantry deflection that can affect accuracy at the far end of a long cantilever design. This makes the 120X OMAX's preferred platform when cutting at the extremes of the travel envelope.
The 120X supports OMAX's full pump and cutting head range, including the EnduroMAX pump at 60,000 PSI in 30 HP, 40 HP, and 50 HP configurations. The bridge gantry is engineered for dual cutting head configurations, making it a popular choice for production shops that want to run two A-Jet heads simultaneously and cut two identical parts per cycle. The full-bridge design also accommodates the OMAX Rotary Axis accessory without the balance concerns that arise on cantilever machines when heavy rotary fixtures are positioned near the extreme Y end of the table.
Positioning accuracy on the 120X is ±0.076 mm (±0.003 in) with ±0.025 mm (±0.001 in) repeatability — the same specification as smaller OMAX machines, achieved through precision ball screw drives on all axes and a rigid bridge that distributes drive forces symmetrically. Rapid traverse reaches 12,700 mm/min (500 ipm). The machine runs Intelli-MAX software with the full suite: Layout for CAD/CAM programming, Make for machine control, and Intelli-VISOR for monitoring and diagnostics.
New OMAX 120X systems typically range from $180,000 to $300,000 depending on pump HP, cutting head configuration, and accessories. Dual-head configurations with A-Jet heads at the upper end of pump options approach $320,000. The 120X occupies the upper tier of OMAX's waterjet lineup alongside the 80160, competing with Flow's Mach 500 3020 and 4020 configurations in the large-format flat-table segment.

Strengths & Limitations
Strengths
- Full bridge gantry eliminates the deflection and accuracy degradation at far-end positions that affect cantilever machines on large cutting envelopes
- Dual cutting head configuration doubles throughput on standard production runs by cutting two identical parts simultaneously
- 50 HP pump option provides meaningful speed advantages over the 20-30 HP range on thick materials, without requiring the complexity of a flow HyperJet
- Intelli-MAX software's familiarity across the OMAX lineup means operators trained on smaller OMAX machines transition to the 120X with minimal retraining
Limitations
- Higher starting price than OMAX's cantilever machines (55100, 80X) for comparable cutting areas due to the bridge gantry structure
- Full bridge structure requires more floor space clearance on both sides of the machine for the gantry rail support columns
- EnduroMAX pump tops out at 60,000 PSI — no 90,000+ PSI ultra-high pressure option available within the OMAX 120X lineup

Frequently Asked Questions
01
A cantilever gantry is supported on only one side (the operator side), so the far end of the gantry beam deflects slightly under the weight of the cutting head, especially on long machines. A bridge gantry is supported on both sides, making it structurally rigid across the entire travel. On a 120-inch machine, this difference in rigidity translates to more consistent accuracy at the far end of the table.
02
The 120X can be configured with two cutting heads mounted side by side on the gantry. Both heads cut simultaneously, executing the same program offset by the head spacing. This doubles throughput when cutting two identical parts placed side by side. Head spacing is fixed at installation, so parts must be nested to fit within the head-to-head distance. Dual-head cutting is most efficient on high-volume production runs of identical parts.
03
The 120X uses OMAX's EnduroMAX direct-drive pump in 30 HP, 40 HP, and 50 HP configurations. The 50 HP option provides the highest cutting speed within the OMAX EnduroMAX range, meaningful for shops cutting 25 mm and thicker materials regularly. Unlike some competitors, OMAX does not offer an ultra-high pressure (90,000+ PSI) option — the maximum is 60,000 PSI across the entire EnduroMAX lineup.
04
With 120 inches (10 ft) of X-axis travel, the 120X can cut parts up to approximately 9 to 9.5 ft in finished length, allowing clearance at both ends of the table for the cutting head lead-in and lead-out moves. Parts very close to the full 120-inch envelope should be verified against the machine's actual usable travel, which accounts for head park position.
05
The 120X (10x5 ft) and the 80160 (approx. 6.7x13.3 ft) serve different format needs. The 120X is optimized for long, narrower parts and standard 3-meter sheet formats. The 80160 has a wider Y-axis (80 in) and handles square or wide large-format sheet stock better. If you regularly cut long narrow profiles, the 120X wins. If you handle large panels closer to square, the 80160 is more versatile.
