UHP Waterjet Deburring TechnologyHigh-pressure waterjet deburring is a precision machining process utilizing ultra-high-pressure waterjet technology.Its core principle: A high-pressure pump pressurizes tap water to dozens to hundreds of MPa. The pressurized water is ejected through a specially engineered nozzle (aperture approx. 0.1–0.5 mm) to form a high-speed water jet (speed up to hundreds of meters per second). When the jet impacts the root of a burr, shear force and wedging action cause the burr to undergo fatigue fracture and peel off instantly, achieving deburring.
As the jet travels away from the nozzle, the continuous stream gradually breaks into droplets and slugs, delivering intermittent impact. Additionally, pressure fluctuations and turbulence upon impact generate cavitation; the shockwaves from cavitation collapse further enhance burr removal.
Burrs are removed mainly by two impact forces:
- Impact from colliding droplets and slugs
- Impact force generated by cavitation

ApplicationsHigh-pressure waterjet deburring and cleaning equipment is widely used for precision deburring, hole cleaning, and surface cleaning of complex components in automotive, hydraulic, die-casting, 3C electronics, medical devices, and aerospace industries.
It is especially suitable for parts with cross holes, deep holes, inner passages, blind holes, and complex inner structures that are difficult to clean by traditional methods.
Typical applications include:
Automotive components: valve bodies, oil passages, cylinder blocks, pump housings, gears, and hydraulic parts
Hydraulic & fluid control parts: manifold blocks, valve plates, flow channel plates, and multi-way valves
Precision die-casting parts: aluminum, zinc, and magnesium die-castings
Machined components: precision metal parts, stainless steel and titanium alloy workpieces
3C & electronic parts: precision structural components and connectors
Medical device parts: precision implants and orthopedic components
Aerospace components: high-precision titanium and aluminum structural parts
The non-contact processing ensures no damage to dimensional accuracy, surface finish, or material properties, making it the ideal precision cleaning and deburring solution for high-end manufacturing.
