Achieving ultra-high aspect ratio cutting. Introducing water jet laser.

Introduction of water jet laser processing technology that enables ultra-high aspect ratio cutting from thin plates. It allows for highly flexible laser processing regardless of the material.

Water jet laser processing is a method that uses water as a medium to transmit laser to the processing point for laser machining. Recently, near-infrared light propagates through a water jet with a diameter of 30 micrometers and reaches the workpiece. 〇 High-quality burr-free cutting 〇 Minimal thermal impact due to the use of water as a medium 〇 No need for focus adjustment 〇 High aspect ratio cutting 〇 Deep micro-drilling 〇 Wide process window We have successfully matched with high-power IR lasers and developed a new method to combine with high-performance fiber lasers. This method reliably couples multi-kilowatt IR laser beams without damaging the water jet nozzle, enabling ultra-high aspect ratio cutting of aluminum over 2 mm thick using a small nozzle of 50 micrometers. The target materials can include a wide range of metals, resins, and ceramics. Please feel free to contact us first.
