Advantages of water jet guided LASER machining
• No continuous focus adjustment needed

Water
20 bar - 500 bar

• 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
• Low running costs
