Alfex CNC Australia plans to showcase the latest laser technology from ACSYS Lasertechnik at the Austech 2012 in Sydney.
As technical demands from the electronic, medical, aerospace and other industries are pushing the boundaries of micro-machining to smaller and more precise tolerances, laser technology is being employed to meet industry needs for smaller geometries and increasingly tighter specifications.
Alfex CNC Australia will demonstrate how extremely accurate 3D engraving and micromachining processes using laser technology from ACSYS Lasertechnik replace conventional CNC machining techniques. The zero physical contact between the laser and the workpiece eliminates tool wear, tool changes and tool breaking.
3D laser engraving allows the three-dimensional surface ablation on a wide range of materials with excellent quality. Alfex CNC Australia will have live demonstrations on its stand over the four days of the show, where an ACSYS Piranha fibre laser system removes material by ablation, thus creating virtually any surface texture that can be digitised.
The process can be used to engrave, mark, label or render a microstructure on a surface in 3D with high speed and precision. The high level of precisely charged laser energy makes it possible to engrave previously hardened materials while providing a working beam diameter down to 20μm.
ACSYS also offers high-resolution camera systems, precision packages and multiple axes systems for high-precision marks such as punch marks, fine engraving or 3D laser micro-engraving. These systems come with up to seven movable linear and rotary axes, consisting of linear moving columns or cross tables and rotary and swivelling dividing heads. With rotary tables, tag feeders, foil handling or special attachments, the Piranha laser system offers optimum adjustment possibilities for any task.
Alfex CNC Director George Buhagiar explains that the system perfectly co-ordinates all details from file creation to laser outputs to ensure an intuitive workflow.
The unique camera set-up module LAS (Live Adjust System) reduces set-up times to a minimum and makes working with the laser highly efficient. The high resolution camera provides a live virtual preview of the workpiece being processed on the computer monitor. ACSYS’ own AC LASER Software allows the user to design texts, 2D and 3D data directly on the workpiece image and to define positions, contours and frostings easily and precisely.
The Optical Parts Recognition system (OPR) allows for fully automatic processing of non-palletised loose parts, where the system will automatically locate each part and then correctly position or even rotate the file to mark in exactly the right place every time, regardless of the orientation of the part on the pallet.
According to Jordan Buhagiar, Sales Team Leader - Laser Division, lasers open up entirely new possibilities in terms of design such as precise surface frosting and unlimited textures with interesting visual effects. Reproducibility of the laser systems is a great advantage in terms of saving time and ensuring consistent quality since any frosting layout can be saved as a file and then automatically transferred to other dies at any time.
Alfex will also showcase the compact MetaBeam 400W laser cutting system from leading laser manufacturer Coherent Inc. USA. CO2 lasers have been used in metal cutting and welding for decades, but the physical size and high operating costs associated with traditional, flowing gas CO2 laser cutting systems have limited their use to larger installations.
The MetaBeam series is designed for precise, laser cutting of a large variety of materials, including stainless steel up to 3mm thick, thanks to its Coherent Diamond series sealed CO2 laser, which allow a more compact, reliable and cost-effective system.
MetaBeam CO2 laser cutting systems have a small footprint, taking up only a fraction of the floor space of conventional larger machines. Laser gas or regular overhauls on the laser are not required thanks to a completely sealed, maintenance-free laser source. The system also uses very little power compared with the larger machines, ensuring excellent ROI.
