The combination of classic laser processing and laser water jet technology by Synova enables highly precise cuts in hard metals—without thermal damage or mechanical wear.

The RDX1000 LWJ is based on Synova's patented Laser MicroJet process, which guides a laser beam over several millimeters in a fine water jet. This keeps the beam guidance stable while simultaneously cooling the material.

Deep Cuts in Thick Materials

Additionally, typical laser ablation processes for cutting often achieve an aspect ratio of only 1:3 to 1:5. This means: a cut width of one hundred micrometers penetrates only up to 500 micrometers deep into the material. For deeper cuts, wider kerfs must be chosen, leading to longer process durations.

With the RDX1000 LWJ, aspect ratios of up to 1:100 become achievable—a dimension that was previously only possible with complex mechanical processes.

Another unique feature is the combination of two processing stations: In addition to the water-guided laser processing, a separate dry processing station is available. This versatility enables the implementation of hybrid processing strategies. Materials can first be structured and then precisely drilled with the laser water jet — an advantage in the manufacturing of complex functional components.

Testing in the Schunk Mach-Lab

The Schunk Group's cross-group application center, Mach-Lab, tests the technology under real manufacturing conditions. Schunk sees great potential, especially in the processing of 3D-printed silicon carbide and in the production of high-precision components for microelectronics.

Precise Cooling Channels and Delicate Micro-Drillings

The aerospace industry is also increasingly using brittle high-performance materials, for example, for turbine blades or heat shield tiles. The RDX1000 LWJ enables deeper and more precise cooling channels in heat-resistant materials without impacting their structure. This reduces component weights and increases efficiency.
