Micro-channel Milling Using Abrasive Waterjets ... Today

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.

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 ...

Abrasive waterjet (AWJ) technology has evolved beyond heavy-duty industrial cutting into a precise solution, specifically for creating intricate micro-channels in hard-to-machine materials. What is Abrasive Waterjet Micro-Milling? Milling can be done with the workpiece submerged

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

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.
