High-Pressure Waterjet
Deburring (HDW)
A precisely directed high-pressure water jet removes burrs while simultaneously cleaning the part. No chemicals, no thermal stress — one process step for deburring and washing.
How Waterjet
Deburring Works
Water is pressurised to 50–1,000 bar and directed through CNC-controlled nozzles at the target locations on the part.
Part fixturing
The part is fixtured on a CNC rotary table or robot. Nozzle positions are programmed for each burr location.
High-pressure jetting
Water at up to 1,000 bar impacts the burr. The kinetic energy shears the burr from the parent material.
Deburring + washing
All loosened particles and chips are flushed away simultaneously. The part exits clean and deburr-free in one step.
Where HDW
Is Used
HDW is widely used in automotive production lines where deburring and washing must be combined in a single automated cell.
Cylinder heads & blocks
Oil galleries, coolant passages and intersection bores are deburred and flushed clean in one cycle.
Hydraulic manifolds
Cross-hole burrs and residual chips are removed with targeted high-pressure jets — no residual particles in the circuit.
Transmission components
Complex gear housings and valve bodies benefit from the combined deburring and washing action.
Brake & ABS components
Safety-critical bore intersections are deburred and verified clean in one automated step.
Why HDW
- Deburring and washing in a single process step
- No chemicals required — water only (with optional corrosion inhibitor)
- No thermal stress — safe for aluminium, zinc and sensitive alloys
- Fully automatable — integrates into CNC production cells
- Precise targeting — nozzles programmed to exact burr locations
- High throughput — short cycle times in series production
- Removes loose chips and contamination simultaneously
- Traceable — easily integrated into production monitoring systems
