Overview
The OMAX 60120 Jet Machining Center is one of OMAX's largest open-architecture abrasive waterjet systems, offering a 60 x 120 inch (1,524 x 3,048 mm) cutting envelope that accommodates full 5x10 foot sheet stock without repositioning. Designed for high-throughput fabrication shops, aerospace suppliers, and metal service centers, the 60120 combines OMAX's proven direct-drive pump technology with the Intelli-MAX software suite to deliver precise, repeatable cuts across virtually any material — steel, aluminum, titanium, stone, glass, composites, and more — without heat-affected zones or tool changes.
At the heart of the 60120 is OMAX's direct-drive pump, available in configurations from 30 to 100 horsepower, generating pressures up to 60,000 psi (4,137 bar). Unlike intensifier-based pumps used by many competitors, OMAX's direct-drive design offers lower maintenance costs, higher energy efficiency, and longer seal life. The Intelli-MAX software calculates optimal tool paths and cutting speeds based on material type, thickness, and required edge quality, making it accessible to operators without deep waterjet experience while enabling seasoned programmers to maximize throughput.
The 60120's large cutting area pairs with OMAX's Tilt-A-Jet cutting head, which compensates for the natural taper inherent in abrasive waterjet cutting by angling the jet to produce virtually taper-free edges on most materials. The optional A-Jet multi-axis cutting head extends capability to 5-axis bevel cutting and sloped surfaces, enabling beveled weld preps, countersinks, and angled features in a single setup. Linear positioning accuracy of ±0.076 mm (±0.003 in) meets the requirements for most structural, architectural, and industrial fabrication applications.
The 60120 competes directly with the Flow Mach 500 and KMT-equipped waterjet systems in the large-format market. OMAX's strong North American dealer network, the Intelli-MAX software's ease of use, and the lower long-term pump maintenance costs are the primary differentiators. New OMAX 60120 systems price from $250,000 to $450,000 depending on pump power, number of cutting heads, and options including the Tilt-A-Jet, rotary axis, and catcher tank configuration.

Strengths & Limitations
Strengths
- Full 5x10 ft cutting envelope handles standard sheet stock without repositioning, maximizing material utilization and reducing setup time
- OMAX direct-drive pump technology delivers lower maintenance costs and higher energy efficiency compared to intensifier-based pump designs
- Intelli-MAX software calculates optimal cutting parameters automatically, reducing operator training time and enabling consistent results across operators
- Tilt-A-Jet cutting head compensates for natural waterjet taper, producing near-taper-free edges without secondary finishing on most applications
Limitations
- Large footprint and significant weight require substantial floor space, structural floor load capacity, and dedicated utilities including high-pressure water and garnet handling
- Abrasive garnet consumption is an ongoing operating cost — large-format machines cutting thick materials can use significant garnet volumes per shift
- 60,000 psi pump seals and high-pressure plumbing require regular preventive maintenance to avoid unplanned downtime during production runs

Frequently Asked Questions
01
The OMAX 60120 can cut virtually any material with abrasive waterjet: steel, stainless steel, aluminum, titanium, Inconel, copper, brass, stone, granite, marble, glass, ceramics, composites, carbon fiber, Kevlar, rubber, foam, plastics, and wood. The only materials waterjet cannot cut are tempered glass (it shatters) and certain ceramics that require diamond tooling. Material thickness up to 8 inches is achievable depending on the material and required edge quality.
02
OMAX's direct-drive pump uses a crankshaft mechanism to pressurize water directly, similar to how a triplex plunger pump works. Intensifier pumps use hydraulic oil at lower pressure to drive a small-bore piston to ultra-high water pressure. Direct-drive pumps generally have lower maintenance costs (no hydraulic oil, simpler sealing systems), higher electrical efficiency, and longer seal life. Intensifier pumps can achieve higher pressures (up to 90,000 psi) but have higher energy consumption and more complex maintenance. For most abrasive waterjet applications at 60,000 psi, direct-drive is the preferred choice.
03
The Tilt-A-Jet is OMAX's patented cutting head option that tilts the waterjet nozzle by a small angle (typically 0.5–2 degrees) to compensate for the natural taper that abrasive waterjet produces as the jet exits the bottom of the material. Without compensation, abrasive waterjet cuts have a slight V-shape — wider at the top, narrower at the bottom. With the Tilt-A-Jet, edges can be cut square or with a controlled bevel. For most industrial applications requiring square edges and tight tolerances, the Tilt-A-Jet is recommended.
04
Operating costs vary by application but typically include: electricity ($5–20/hour depending on pump power), garnet abrasive ($3–8/hour at typical feed rates), orifice replacement (every 100–500 hours, approximately $15–30 each), focusing tube replacement (every 50–200 hours, approximately $50–150), and water treatment. Total consumable costs for abrasive waterjet typically run $15–40 per hour of cutting time depending on material thickness and garnet usage rate.
05
The standard 60120 is a 3-axis machine (X, Y, Z). 5-axis capability requires the optional A-Jet multi-axis cutting head, which adds two rotational axes and enables bevel cutting, sloped surfaces, countersinks, and weld prep bevels in a single setup. The A-Jet is available as a factory option or field upgrade. For shops primarily cutting flat profiles, the standard 3-axis configuration with Tilt-A-Jet for taper compensation is sufficient.
