How much does the OMAX 120X cost?
Estimated price range
Our best estimate for a cnc waterjet cutting in this class — not a quote from OMAX Corporation. Configuration moves it a long way.
Overview
The OMAX 120X is a large-format waterjet: 20′ x 10′ (6.06 m x 3.04 m) of X-Y cutting travel over a 21′ x 11′ 5″ (6.40 m x 3.48 m) table, with 8" (203 mm) of Z travel and 60,000 psi output pressure. A machine this size is a building decision as much as a machine decision.
Start with the space. The footprint is 33′ 3″ x 19′ 5″ (10.13 m x 5.92 m) and the height is 14′ (4.27 m), before any allowance for loading plate from the side or overhead. OMAX lists the weight with the tank empty at 22,000 lb (9,979 kg). The table for this model has no operating-weight row, and a tank of this area holds a great deal of water, so ask for the filled weight before the slab is assessed.
The travel is long enough to lay several sheets end to end and cut them in one program, or to cut one long plate without indexing it. For scale, the 55100 has a 10'6" x 5'5" (3.20 m x 1.65 m) table, half the length of this one and less than half the width. The slats are 4″ x 1/8″ galvanized steel and support 400 lbs/sq ft (1,950 kg/sq meter).
Size has not been traded for accuracy on the linear figures: positional accuracy and repeatability are both ±0.001″ (±0.025 mm). Ballbar circularity is ±0.005″ (±0.127 mm). Speed is listed at 350 in/min (8,890 mm/min), which matters here because the head has a long way to go between parts. Supply is 3-Phase, 380-480 VAC ±10%, 50-60 Hz, and noise is below 80 dBA at one meter for submerged cutting.

Strengths & Limitations
Strengths
- 20′ x 10′ (6.06 m x 3.04 m) of cutting travel on a 21′ x 11′ 5″ (6.40 m x 3.48 m) table
- ±0.001″ (±0.025 mm) linear positional accuracy and repeatability across that envelope
- 350 in/min (8,890 mm/min) listed speed shortens the moves between widely spaced parts
- 400 lbs/sq ft (1,950 kg/sq meter) supported load on 4″ x 1/8″ galvanized steel slats
- 60,000 psi output pressure and 8" (203 mm) of Z travel
Limitations
- Needs 33′ 3″ x 19′ 5″ (10.13 m x 5.92 m) of floor and 14′ (4.27 m) of height before loading access is added
- Only the tank-empty weight, 22,000 lb (9,979 kg), is listed; the filled weight has to be requested for floor design
- Ballbar circularity is ±0.005″ (±0.127 mm), looser than the ±0.001″ (±0.025 mm) linear figure
- Z travel is 8" (203 mm), no more than the much smaller 2652 has

Frequently Asked Questions
01
The footprint is 33′ 3″ x 19′ 5″ (10.13 m x 5.92 m) and the machine is 14′ (4.27 m) high. Those are the machine's own dimensions. Space to bring plate to the table and to walk around it comes on top.
02
X-Y cutting travel is 20′ x 10′ (6.06 m x 3.04 m) with 8" (203 mm) of Z travel. The table is 21′ x 11′ 5″ (6.40 m x 3.48 m), so plate can sit slightly beyond the cut area on every side.
03
OMAX lists 22,000 lb (9,979 kg) with the tank empty. No operating weight is given in the table for this model, so the filled weight, which is the number a structural engineer needs, has to be requested. Material load comes on top, at up to 400 lbs/sq ft (1,950 kg/sq meter) on the slats.
04
It is the largest table of the three. The 120X table is 21′ x 11′ 5″ (6.40 m x 3.48 m), the 55100 table is 10'6" x 5'5" (3.20 m x 1.65 m) and the 2652 table is 5′ 9″ x 2' 6″ (1.75 m x 0.76 m). The 2652 lists the same 8″ (203 mm) Z travel and 400 lbs/sq ft (1,950 kg/sq meter) rating as the 120X.
05
Not on the linear figures. Linear positional accuracy and repeatability are both ±0.001″ (±0.025 mm). Ballbar circularity, which reflects both axes moving together, is ±0.005″ (±0.127 mm), so round features are held less closely than straight moves.
