How much does the WardJet R-4020 CNC Waterjet Cutting Machine cost?
Estimated price range
Our best estimate for a cnc waterjet cutting in this class — not a quote from WardJet. Configuration moves it a long way.
Overview
The WARDJet R-4020 is an abrasive waterjet with a 4,000 x 2,000 mm (157 x 79 in) cutting area and the option of a second cutting head. It is not a model WARDJet shows in its lineup now; the listed figures are the basis for judging a machine that is already in the field.
The drive layout is split by axis. The 4,000 mm X axis runs on rack-and-pinion, while Y and Z use ballscrews, all with servo motors. That puts the rack on the long travel, where a screw would be impractical, and keeps screws on the two shorter axes. Listed positioning accuracy is ± 0.1 mm with repeatability of ± 0.05 mm, and rapid traverse reaches 10,000 mm/min.
Cutting head options are single or dual abrasive waterjet heads. Two heads cut two identical parts at once, which pays on repeat batches, but both draw from one pump, and the listed figures give only a pressure limit, up to 60,000 psi (4,137 bar), with no pump power. For a dual-head machine, check that the installed pump can feed both nozzles at the orifice size you intend to run.
Z travel is 200 mm, which bounds the height of the part plus any fixture beneath it. The table is welded steel with sacrificial slat support, the abrasive is garnet in mesh 80 or 120, and the WARD CNC control imports DXF files and nests parts.

Strengths & Limitations
Strengths
- 4,000 x 2,000 mm (157 x 79 in) cutting area
- Single or dual abrasive waterjet heads; the dual arrangement cuts two identical parts together
- Repeatability of ± 0.05 mm alongside ± 0.1 mm positioning accuracy
- Rack-and-pinion on X with ballscrews on Y and Z, all servo driven
- Rapid traverse of 10,000 mm/min
Limitations
- Compatible pump pressure stops at 60,000 psi (4,137 bar)
- No pump power is listed, which matters most when two heads share one pump
- Z travel of 200 mm caps the combined height of part and fixture
- The listed head options are single or dual abrasive heads only; no tilting head is among them

Frequently Asked Questions
01
4,000 x 2,000 mm (157 x 79 in) in X and Y, with 200 mm of Z travel. The long axis is X, which is the one driven by rack-and-pinion.
02
Yes, the listed head options are single or dual abrasive waterjet heads. A dual-head machine doubles output only on jobs where both heads cut the same shape, and it needs a pump large enough for two nozzles. No pump power is listed, so verify the pump on the machine.
03
The listed figures are ± 0.1 mm positioning accuracy and ± 0.05 mm repeatability. Those describe where the head goes; the finished edge also depends on jet taper, cutting speed and nozzle wear, which no table can state.
04
Servo motors on all axes, through rack-and-pinion on X and ballscrews on Y and Z. Maximum rapid traverse is 10,000 mm/min. On a used machine, inspect the X rack and the Y ballscrew separately, as they wear in different ways.
