Component Processing

High-pressure waterjet deburring for edges, bores, and internal contours.

In high-pressure waterjet deburring, machining burrs and adhering residue are removed using precisely guided water jets. The process is particularly attractive when hard-to-reach geometries must be processed reproducibly.

The burr and the part determine the jet strategy

Deburring must deliver enough energy at the burr without impermissibly altering function-relevant contours of the part. What matters is the location and extent of the burr, the material, the edge or bore geometry, and the permitted change to the surface.

Orifice, stand-off, angle, and dwell time are matched to the geometry

Hard-to-reach cross-drilled holes or internal contours require a different jet approach than freely accessible outer edges. In automated processes, tool position, motion path, and processing time are set so that every relevant location is reached reproducibly.

Deburring systems are often enclosed processing systems

For series parts, an enclosed cell with defined part fixturing and automated nozzle guidance is a common approach. Filtration, part handling, drying, and process monitoring can also be integrated into the system. The system concept depends heavily on cycle time, required part cleanliness, and the degree of automation needed.

Acceptance criteria must be fixed before trials begin

A defensible process release needs measurable criteria: which burrs may remain? What edge change is permitted? What residual contamination is acceptable? Only with defined inspection characteristics can trials and vendor quotes be compared on a technical basis.
