Q What is a water jet cutter?
A A water jet cutter is an industrial CNC machine that cuts materials using a hyper-pressurized (up to 90,000 PSI) water stream mixed with abrasive garnet. Unlike thermal methods, it operates as a cold-cutting process, eliminating heat-induced distortions.
Key components include:
-abrasive cutting head
- CNC controller
- Ultra-high-pressure intensifier pump
-
Q How does a waterjet cutter work?
A The process involves three stages:
1. Pressurization: Water is compressed to 60,000–90,000 PSI.
2. Abrasive injection: Garnet enters the stream in a mixing tube, transforming water into a micro-erosion tool.
3. Cutting: The abrasive jet travels at Mach 3 (2,500 km/h), eroding material particle-by-particle.
Pure water mode (no abrasives) cuts soft materials like food or foam.

Q What sets modern waterjets apart?
A Hybrid machining:
Integrates drilling, milling, and polishing in one platform.
Smart features:
IoT-enabled predictive maintenance + automated abrasive dosing.
Safety:
Non-toxic process (no fumes/dust) and Class 1 safety certification.
-
Q Is waterjet cutting eco-friendly?
A Yes, water jet cutting is extremely environmentally friendly and has the following advantages:
Abrasive recycling: 90% garnet recovery rate.
Water reuse: Closed-loop filtration systems reduce consumption by 80%.
Energy efficiency: 4kW average power draw (vs. 20kW+ for plasma).
-
Q What is the cutting accuracy and repeat positioning accuracy of the machine?
A Standard CNC waterjet cutting machine precision metrics:
Positioning Accuracy: ±0.05mm (or ±0.002 in)
Repeatability: ±0.025mm (or ±0.0008 in)
(Taper compensation heads further improve vertical edge precision on thick materials).
-
Q What power supply and utility requirements are needed to run the waterjet machine?
A Power: Requires a 3-phase industrial power supply (e.g., 380V/415V/480V, 50Hz/60Hz, depending on your local grid).
Water Supply: Requires clean inlet water (softened/filtered water is recommended to prolong high-pressure seal life).
Compressed Air: Clean, dry compressed air (approx. 0.6–0.8 MPa) is required for pneumatic valve operation and abrasive delivery.
-
Q What is the difference between Direct Drive pumps and Intensifier pumps?
A Intensifier Pump: Ideal for heavy-duty industrial applications, offering stable high pressure (up to 400 MPa / 60,000 psi or higher) and continuous long-hour operation.
Direct Drive Pump: Highly energy-efficient (up to 85–90% power conversion), quiet, and suitable for low-to-medium continuous production needs.
