DML Deckel Maho Ablator Laser Ablation system

The CSIR National Laser Centre has a laser ablation system that is used for deep engraving or laser milling tasks. Laser ablation is a process where very thin layers of material are removed from a surface in a controlled way by laser pulses emitted by laser source. This 40 micron diameter focused laser spot is guided over a surface at a fast rate, employing a series of guiding mirrors. The process is controlled by computer assisted machining software. This enables the creation of very fine profiles and structures in most metals as well as ceramics by evaporating the unwanted material. The result is then a small tool or prototype that is within specification. This process relates mostly to tooling in the coining, plastic injection moulding and printing industries. Miniature prototypes and aerospace components are developed with this advanced technology.
