Micro-channel Milling Using Abrasive Waterjets ... (2026)

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

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?

Fabrication of microfluidic channels and texturing of medical implants. MICRO-CHANNEL MILLING USING ABRASIVE WATERJETS ...

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

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. This process uses a high-velocity stream of water

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

It can machine virtually any material, including high-strength alloys (316L stainless steel), brittle ceramics (PZT), composites, and laminates. What is Abrasive Waterjet Micro-Milling

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