Model and installed configuration
OMAX lists ±0.076 mm linear positional accuracy at 22°C. The ballbar row prints ±0.007 in and ±0.0178 mm, but 0.007 in × 25.4 = 0.1778 mm. That flags a unit mismatch. Confirm the intended specification from controlled documentation. Axis positioning leaves finished-edge taper and size to verify on the actual cut. See the through-thickness slot example. OMAX GlobalMAX 2040
The listed 10, 20 and 30 hp pumps pair 30,000, 45,000 and 45,000 psi output pressures with maximum recommended orifices of 0.011, 0.012 and 0.015 in, respectively. The 30 hp metric orifice entry also conflicts with its inch value. MAKE estimates use pressure at the nozzle, where plumbing losses can change the pressure. Check the installed orifice, mixing tube and abrasive feed. OMAX pump table, GlobalMAX pump and nozzle configuration
Capacity is not a finished-part tolerance
The current product page lists the following values, reviewed November 1, 2026:
| Characteristic | Listed value and scope |
|---|---|
| X–Y cutting travel | 4.03 × 2.03 m |
| Table size | 4.14 × 2.18 m |
| Z travel | 127 mm with motorized Z axis |
| Maximum supported material load | 488 kg/m² |
| Linear positional accuracy | ±0.076 mm |
| Linear repeatability | ±0.025 mm |
OMAX states that accessories can reduce travel and that accuracy specifications are at 22°C. Table dimensions do not establish the usable cutting envelope. Z travel is not a guaranteed material-thickness capacity. OMAX product specifications
Resolve the ballbar mismatch against the applicable controlled specification and measurement conditions. Establish measured circularity on the installed machine separately. OMAX product table
Check representative features on the actual material and thickness. Speed, geometry, nozzle condition and kerf compensation affect the cut edge. OMAX cutting-tolerance guidance
Pump and nozzle choices affect the cutting model
The 30 hp orifice row has a second unit mismatch: 0.015 in × 25.4 = 0.381 mm, while the table pairs 0.015 in with 0.33 mm. The conversion identifies the conflict. Confirm the applicable orifice in the installed pump and nozzle documentation before selection. OMAX GlobalMAX pump table
MAKE calculates abrasive feed and nozzle speed from pump and nozzle inputs. Record nozzle pressure, orifice and mixing-tube diameters, measured abrasive flow and abrasive size with their units. GlobalMAX pump and nozzle configuration
MAKE controls motion and water and abrasive flow. Its offline estimates also support quoting and reporting. Check setup and stock restraint at the machine. GlobalMAX MAKE overview
Check support, clearance and the planned path
Original load-screen example: a uniformly supported 2 m² sheet weighing 800 kg represents 400 kg/m², below the listed 488 kg/m² figure. This comparison alone does not qualify the setup. Actual support distribution, slat condition, concentrated loads, clamps and the installed machine's instructions still matter; a point load cannot be assessed by dividing it by the whole table area.
GlobalMAX's dry-run function moves the planned path without water or abrasive and is intended to help check fixture and material clearance. The help specifically warns that resuming after a paused dry run requires selecting dry-run mode again; ordinary Continue can resume full cutting. A dry run checks motion, not penetration, edge finish or dimensional acceptance. Follow the machine's operating procedure and keep personnel clear of moving equipment. GlobalMAX dry-run guidance
Maintain a process-specific quality record
Retain material grade/thickness, geometry revision, nozzle and abrasive configuration, software inputs, intended cut quality, kerf compensation, fixture plan and inspection results. Check both faces and relevant edge locations when taper matters. OMAX discusses taper-compensating options for other machine lines; do not infer that such a head is installed on a GlobalMAX from a general process article. OMAX tolerance and configuration guidance
Water supply and maintenance are part of readiness. OMAX explains that dissolved minerals and water temperature can affect pump, seal and plumbing life. Obtain the requirements for the installed pump and assess the actual supply; a generic water-filter description is not evidence that those requirements are met. OMAX water quality and temperature
For a facility, load or acceptance decision, confirm the serial number, pump, software version, motorized Z and accessories against the installation drawing and controlled specifications.
