Micro-channel Milling Using Abrasive Waterjets ... 〈NEWEST 2025〉

This process uses a high-velocity stream of water mixed with fine abrasive particles (typically garnet) to erode material at a microscopic level. Recent advancements in (with diameters as small as 0.2 mm or 0.3 mm) allow for the milling of narrow, controlled-depth channels. Why it’s a Game-Changer for Micro-Channels

It can machine virtually any material, including high-strength alloys (316L stainless steel), brittle ceramics (PZT), composites, and laminates. 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. This process uses a high-velocity stream of water

Dicing microelectronic wafers and machining piezoelectric materials without risk of electrical shorts between layers. The erosion rate is not constant; it typically

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.

While powerful, the process requires high capital investment and precision control to manage the jet's inherent instability and tool wear in the nozzle. Abrasive waterjet micro-machining of channels in metals

Shaping heat-sensitive components and thin-walled aluminum parts prone to distortion.
