Laser job-shop micro cutting made easy / from ultra-thin up to ultra high-aspect cutting

Problem

Conventional precise laser micro cutting of different materials, material thicknesses as well as surface topographies can be a challenge. Different focal lengths and cutting strategies as well as post-processing and de-burring can be required.


Solution

The Avonisys waterjet guided laser system can simplify the precise laser micro cutting of different materials, material thicknesses and surface topographies. As the laser energy is contained inside the constant diameter of a long yet narrow waterjet different materials of different thicknesses can be handled without changing the cutting configuration. Whether rapidly cutting 0,05mm thin stainless steel sheets in a single pass - or cutting 10mm thick silicon or aluminum in multiple passes - the Avonisys waterjet laser system does so with the exact same laser source, the exact same laser head and the exact same cutting configuration. The only variable it the amount of scan passes and the selected laser parameter based on work piece material.


A small selection of work pieces (as-cut results) made with with exact same system configuration is shown below:

Benefits of the waterjet guided laser

The energy of the laser focus is coupled into a thin liquid-jet, where it is guided to the work piece by total internal reflection. The energetic diameter of the laser beam remains constant over a large working distance of up to several centimetres. Typical tool diameters of the liquid-jet are 0.03 - 0.08 mm.


Using this “infinite” focus laser beam, thin materials can be cut in a single pass, while thicker materials can be precisely cut (or drilled) using a multi-pass cutting strategy. All while maintaining the same narrow, parallel and burr-free cutting kerf.

MICRO HONEYCOMB CUTTING

Laser cutting of very thin walls can already be a challenge. In this video we up the game by cutting 0.25mm thin walls over a large depth of 18mm.


ROBUST WATERJET LASER

Precise alignment and part fixation are not always required to get great results. In this video we show how simple it can be to cut parts with an Avonisys system.


HOLE MATRIX DRILLING

In this video we drill a series of 0.8mm diameter holes in a 5mm thick Nickel alloy as used for turbine applications. The process works robust and uninterrupted.


BURR FREE CUTTING

In this video we show quick freeform cutting of steel sheet material. The results is completely burr free on the front and the back side of the material.
