Overview

The OMAX 120X Jet Machining Center is OMAX's large-format waterjet platform, purpose-built for industries that routinely process sheet and plate stock up to 120 inches (10 feet) in width. It serves aerospace structural component manufacturers, shipbuilders, architectural fabricators, and heavy industrial suppliers who cannot afford to segment large blanks before cutting.

The 120X pairs OMAX's high-power EnduroMAX pump — available in 50 HP or 100 HP dual-pump configurations — with a robust bridge-style gantry that maintains accuracy across the full travel envelope. Precision linear encoders and ball screw drives ensure the machine holds ±0.001 inch positional accuracy even at the far extents of the table, where lesser systems experience deflection-induced error.

OMAX's Intelli-MAX software drives the 120X with the same interface used across the entire JMC line, reducing operator retraining when shops add the large-format machine alongside smaller units. Advanced nesting tools maximize material utilization on large plates, and the integrated path optimizer reduces non-cutting travel on complex multi-part jobs. Optional automation features include programmable height sensing and automatic garnet delivery systems.

For shops cutting thick plate — structural steel, aluminum extrusions, titanium billets, or armor — the 120X can be configured with dual cutting heads running in tandem, effectively doubling throughput without doubling floor space. The machine's open architecture makes it compatible with OMAX's A-Jet 5-axis cutting head, enabling complex bevel and chamfer cuts on structural parts that previously required dedicated milling or plasma operations.

Strengths & Limitations

Strengths

120-inch cutting width processes full aerospace and shipbuilding plate without pre-cutting
Dual cutting head option doubles throughput on production runs without added floor space
±0.001 in accuracy maintained across the full large-format travel envelope
Compatible with A-Jet 5-axis head for bevel cuts on structural components
Same Intelli-MAX software as smaller OMAX JMCs — no retraining for multi-machine shops

Limitations

Large capital investment and significant floor space requirement limit accessibility for small shops
High-volume garnet consumption at full power increases consumable operating costs substantially
Installation requires significant facility preparation including reinforced flooring and three-phase power

Frequently Asked Questions

01 What is the maximum cutting width of the OMAX 120X?

The standard 120X provides 120 inches (10 feet) of X-axis travel with 60 inches of Y-axis travel. Extended Y-axis configurations are available for even larger cutting envelopes.

02 Can the 120X run two cutting heads simultaneously?

Yes. The 120X supports dual cutting heads running in tandem. Intelli-MAX software coordinates both heads, effectively doubling throughput on mirrored or parallel part programs.

03 What pump power does the OMAX 120X use?

The 120X is available with a 50 HP single EnduroMAX pump or a 100 HP dual-pump configuration for maximum cutting speed and head redundancy in production environments.

04 Is the 120X suitable for cutting aerospace titanium?

Yes. The 120X excels at cutting titanium plate and billet at thicknesses up to 4–6 inches, producing no heat-affected zone — critical for aerospace structural and fastener applications.

05 What facility requirements does the OMAX 120X need?

The 120X requires three-phase 480V power (single or dual pump depending on configuration), a water supply with sufficient flow, reinforced concrete flooring, and drain access. OMAX provides site preparation guidelines during the sales process.
