How much does the OMAX 120X Jet Machining Center cost?
Estimated price range
Our best estimate for a cnc waterjet cutting in this class — not a quote from OMAX. Configuration moves it a long way.
Overview
Speed and reach define the OMAX 120X Jet Machining Center. The head moves at a listed 350 in/min (8,890 mm/min) over X-Y cutting travel of 20′ x 10′ (6.06 m x 3.04 m), holding ±0.001″ (±0.025 mm) for linear positional accuracy and for repeatability.
On an envelope this long, traverse speed is not a detail. A nest spread over 6.06 m spends real time moving between pierces, and a faster head gets that time back on every sheet. The second accuracy figure deserves a look too: ballbar circularity is ±0.005″ (±0.127 mm), so where a job is mostly holes and arcs, tolerance should be judged against that number and not the linear one.
The work surface is 21′ x 11′ 5″ (6.40 m x 3.48 m) of 4″ x 1/8″ galvanized steel slats, rated at 400 lbs/sq ft (1,950 kg/sq meter). Z travel is 8" (203 mm). Those two rows are identical on the 2652 Jet Machining Center, whose table is 5′ 9″ x 2' 6″ (1.75 m x 0.76 m), and the 55100 Jet Machining Center has the same Z and load rating on a 10′ 6″ x 5' 5″ (3.20 m x 1.65 m) table. The 120X is therefore the same class of bed stretched in length and width.
Output pressure is 60,000 psi. The machine measures 33′ 3″ x 19′ 5″ (10.13 m x 5.92 m) on the floor and 14′ (4.27 m) in height, and weighs 22,000 lb (9,979 kg) with the tank empty. It runs on 3-Phase, 380-480 VAC ±10%, 50-60 Hz. Noise is stated as below 80 dBA at one meter for submerged cutting.

Strengths & Limitations
Strengths
- Listed speed of 350 in/min (8,890 mm/min) for moves across a 6.06 m long envelope
- Linear positional accuracy and repeatability of ±0.001″ (±0.025 mm)
- One setup covers 20′ x 10′ (6.06 m x 3.04 m)
- Same 8" (203 mm) Z travel and 400 lbs/sq ft (1,950 kg/sq meter) bed rating as the 55100 Jet Machining Center, on a table twice as long
- Noise below 80 dBA at one meter for submerged cutting
Limitations
- Ballbar circularity is ±0.005″ (±0.127 mm), five times the linear accuracy figure
- A 33′ 3″ x 19′ 5″ (10.13 m x 5.92 m) footprint and 14′ (4.27 m) height rule out many existing bays
- The table gives no weight for the filled machine, only 22,000 lb (9,979 kg) with the tank empty
- No pump power or cutting-rate row is listed, so productivity in a given material cannot be read from the table

Frequently Asked Questions
01
Speed is listed at 350 in/min (8,890 mm/min). That describes how quickly the head moves, which shortens the time between cuts on a 20′ x 10′ (6.06 m x 3.04 m) envelope. Cutting rate in a given material and thickness depends on the pump and the job, and is not a table figure.
02
The table separates the two. Linear positional accuracy is ±0.001″ (±0.025 mm) and repeatability is the same. Ballbar circularity, the measure of both axes interpolating a circle, is ±0.005″ (±0.127 mm). Plan round features around the looser figure.
03
The bed is 21′ x 11′ 5″ (6.40 m x 3.48 m) of 4″ x 1/8″ galvanized steel slats, rated at 400 lbs/sq ft (1,950 kg/sq meter). Z travel above it is 8" (203 mm).
04
Floor area of 33′ 3″ x 19′ 5″ (10.13 m x 5.92 m), 14′ (4.27 m) of height, and a 3-Phase, 380-480 VAC ±10%, 50-60 Hz supply. The listed weight is 22,000 lb (9,979 kg) with the tank empty; get the filled weight before the floor is approved.
