LASER micro-machining by Posalux - i Water jet guided LASER Synova technology integrated in new Posalux mass production equipment. Enables high productivity, precision and quality dedicated to Powertrain Automotive drilling applications such as hole machining in gasoline conventional or direct injection nozzles. Gasoline nozzle 500 jjm Micro Machining: • Smallest drillable diameter: 100 jjm • Wall thickness / hole diameter ratio: up to 3 • High positioning accuracy • High productivity: 3s / hole • Excellent flow stability • Excellent surface roughness Hole diameter 160jjm, 0.2mm thickness 100 jm dvantages of water jet guided LASER machining: • No continuous focus adjustment needed • LASER beam guided by the water jet • Heat affected zone avoided due to water cooling effect • Water jet prevents particles deposition, contamination and burrs formation • No 'backwall' issue • Low running costs LASER beam Total internai reflection of LASER beam s Water 20 bar - 500 bar Water chamber Nozzle Work pièce Synova Principle: LASER guided by water
