Micro-machining systems can cut, drill and etch precise micro-features quickly and cleanly into a wide range of materials used in MEMS and MEOMS applications.
Lasers micro-machine medical devices, instruments
Precisely metered drug delivery systems, microfluidic structures, catheters, stents, aerosol nozzles and many other medical devices can benefit fromlaser micro-machining techniques.
By using the latest high speed laser technology and a team of specialist engineers, Oxford Lasers can offer cost effective sub-contract micro machining services for medical, semiconductor, microelectronic, NDT, pharmaceutical and many other applications.
Oxford Lasers' three fully equipped micro machining Applications Laboratories give customers the benefit of infrared, visible and UV lasers with multi-axis part manipulation.
Trepanning heads, optical and electron microscopes, vision systems for part location, and CAD/CAM file conversion are all available for use in drilling, milling, cutting and scribing processes.
For example Oxford Lasers developed a new, fast and highly precise method of producing capillary reservoir pins for use in micro-arrays.
The narrow kerf of laser micro machining makes it possible to fabricate these tungsten pins featuring a 10 micron wide capillary slot leading to a reservoir 1000 microns long and 100 microns wide.
Not only is laser machining the only way to achieve this and more complex geometries but its high speed capability is 10-20 times faster than any other processing, making it more economical for high volume production.
As well as tungsten, Oxford Lasers Applications Laboratories can process steel and most other metals, silicon, diamond, ceramics (including alumina, zirconia and silicon nitride), sapphire, silicon carbide, silica, glass, polymers and other transmissive materials.
