5-Axis Air Bearing Positioning System

ABTech’s 5-Axis air bearing project was designed and built for the National Ignition Facility at Lawrence Livermore Labs. The National Ignition Facility, or NIF is a stadium sized facility used to study advances in Fusion energy and it contains 192 laser beams that are focused onto a single target that is only 0.022” in diameter. These targets are made up of several double shell layers that are diamond turned and epoxied together…

Multi-functional Air Bearing Machines for NASA NuStar X-ray Telescope

NASA needed a machine that would safely and quickly produce optics for their long-delayed NuSTAR X-ray telescope. The scientists at NASA challenged ABTech to develop a multifunctional machine that would act as a diamond turning lathe, an indexing tool for raster grinding and an assembly station – all in one. ABTech met the challenge. Two machines were delivered to Columbia University’s Nevis Astrophysics Lab in quick fashion, putting the project back on schedule.

Sonnax Air Bearing Lathe and Metrology Work Cell

Increasingly tighter part tolerances on transmission parts made it more difficult for typical off-shore sourcing channels to meet the quality standards being demanded by the major automotive manufacturers. To solve this international sourcing logistics problem, a leading manufacturer of OEM automotive parts contracted ABTech to design and manufacture a turnkey work cell.

Custom Rail Air Bearing Imaging Spindle

ABTech designed a set of three high-speed air bearing spindles that were synchronized for the 3-dimensional image scanning and inline inspection, to inspect the track, switches, tunnels and bridges for potential maintenance issues, the system was mounted on a dedicated rail car traveling at 75 mph allowing the spindles to create a 3-D image of the rail every 10 cm (less than 4″).

5-Axis Air Bearing Optical Measurement Metrology Platform

OptiPro Systems, a well-respected optical machine manufacturer, contacted ABTech thinking they simply needed a supplier of air bearing stages for development of a prototype metrology station. When the dust settled, the best path to their solution was leveraging OptiPro’s core competencies in optics and ABTech’s core competencies in air bearing-based metrology systems.

AT400 Direct Drive Rotary Air Bearing Installed at the South Pole

Researchers at Princeton University needed a large diameter ultra-precision rotational axis with a motor drive. Sounds routine. But there were some catches that made this project more than a bit unusual.
• First, the entire research project needed to be installed on the top of a rotary table.
• Second, they needed to run their tests continuously over a period of several weeks.
• Third, their sensitivity level was so high that the system had to be installed at the South Pole to eliminate the effects of the earth’s rotation!
