Waterjets ...: Micro-channel Milling Using Abrasive

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

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 MICRO-CHANNEL MILLING USING ABRASIVE WATERJETS ...
