Micro-channel Milling Using Abrasive Waterjets ... ✧

The erosion rate is not constant; it typically decreases as the channel gets deeper. Specialized models are used to predict the final topography for deep channels.

Standard tolerances can reach as low as ±0.01 mm , with surface roughness values (Ra) often below 0.8 µm in hard materials. Common Applications MICRO-CHANNEL MILLING USING ABRASIVE WATERJETS ...

The mechanical erosion process leaves a clean surface without the recast layers often found in wire EDM or laser cutting. Key Technical Insights The erosion rate is not constant; it typically

Unlike lasers, AWJ is a non-thermal process. It eliminates heat-affected zones (HAZ), preventing thermal distortion or changes in the material's properties. Common Applications The mechanical erosion process leaves a

Dicing microelectronic wafers and machining piezoelectric materials without risk of electrical shorts between layers.

Milling can be done with the workpiece submerged in water to reduce noise and contain debris. Submerged machining often results in narrower channels due to the surrounding fluid affecting the jet's expansion.
