How much does the OMAX 55100 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 55100 is a mid-size waterjet with 8'4" x 4'7" (2.54 m x 1.39 m) of X-Y cutting travel on a 10'6" x 5'5" (3.20 m x 1.65 m) table, 8" (203 mm) of Z-axis travel and a maximum pressure of 60,000 PSI (4,137 bar).
Three cutting heads are listed for it: Standard, Tilt-A-Jet and A-Jet (5-axis). The head is the choice that changes what the machine can make. A fixed vertical head cuts profiles, while a 5-axis head can put bevels and angled edges on the same blank, so settle which one the work needs before comparing anything else.
OMAX states three accuracy figures. Linear positional accuracy and repeatability are both ±0.001" (±0.025 mm). Ballbar circularity is ±0.0025" (±0.064 mm), and it is the more telling number for bores, arcs and round parts, because it measures how true a circle the X and Y axes trace when they move together instead of one at a time. Speed is listed at 180 in/min (4,572 mm/min).
Material sits on 4" x 1/8" galvanized steel slats, with a maximum supported material load of 400 lbs/sq ft (1,950 kg/sq meter). Garnet is the abrasive, with 80 mesh as the standard grade.
The machine is 10' (3.05 m) high. OMAX lists a weight of 7,960 lb (3,611 kg) and an operating weight of 21,147 lb (9,592 kg); the second is what the floor carries once the tank is full. Power 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
- Cutting head choices include Tilt-A-Jet and the 5-axis A-Jet as well as the Standard head
- Ballbar circularity of ±0.0025" (±0.064 mm) is published alongside ±0.001" (±0.025 mm) linear positional accuracy
- 8'4" x 4'7" (2.54 m x 1.39 m) of cutting travel on a 10'6" x 5'5" (3.20 m x 1.65 m) table
- Maximum pressure of 60,000 PSI (4,137 bar)
- Supports 400 lbs/sq ft (1,950 kg/sq meter) of material on galvanized steel slats
- 8" (203 mm) of Z-axis travel for thick or raised work
Limitations
- Tilt-A-Jet and A-Jet appear as head options next to the Standard head, so bevel and 5-axis cutting should not be assumed on a base machine
- Operating weight of 21,147 lb (9,592 kg) calls for a floor check before installation
- Speed is listed at 180 in/min (4,572 mm/min)
- Needs 3-Phase, 380-480 VAC power and 10' (3.05 m) of headroom

Frequently Asked Questions
01
The cutting head row lists three: Standard, Tilt-A-Jet and A-Jet (5-axis). They are options to choose between, so confirm which head a given machine is configured with. The A-Jet is the one identified as 5-axis.
02
Ballbar circularity, ±0.0025" (±0.064 mm) on the 55100, describes how closely the machine follows a circle when X and Y move together. Linear positional accuracy, ±0.001" (±0.025 mm), describes straight moves along an axis. For holes, arcs and round blanks the circularity figure is the more relevant of the two.
03
The table is 10'6" x 5'5" (3.20 m x 1.65 m) and the X-Y cutting travel is 8'4" x 4'7" (2.54 m x 1.39 m). A sheet can cover the table, but the nozzle reaches only the travel area, with 8" (203 mm) of Z-axis travel.
04
By table size it is the middle machine. The 2652 has a 5′ 9″ x 2' 6″ (1.75 m x 0.76 m) table and the 120X a 21′ x 11′ 5″ (6.40 m x 3.48 m) table, against 10'6" x 5'5" (3.20 m x 1.65 m) here. All three list 8″ (203 mm) of Z travel and 400 lbs/sq ft (1,950 kg/sq meter) of supported load.
05
OMAX lists a weight of 7,960 lb (3,611 kg) and an operating weight of 21,147 lb (9,592 kg). Electrical requirements are 3-Phase, 380-480 VAC ±10%, 50-60 Hz. Height is 10' (3.05 m).
