Rotary Motion Case Studies

The engineers at the University of California’s Lawrence Livermore Labs needed a target assembly station with a position accuracy of 4 millionths of an inch – that’s 0.0000004 inches (or 0.01 microns!). ABTech delivered. One of the design challenges was that the completed system had to have a small footprint. Not that big a deal, [Read More]

The Challenge Design an inspection system for a European high-speed rail system – that must function accurately in harsh conditions while moving 75 mph. The Design Solution We 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 [Read More]

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.   The objective [Read More]

OptiPro Systems, a well-respected optical machine manufacturer, contacted ABTech thinking that they simply needed a supplier of air bearing stages to enable them to develop a prototype metrology station. When the dust settled, they left with a complete motion system. The reason was simple: core competencies. We didn’t set out to up-sell OptiPro. We set [Read More]

NASA needed a machine that would safely and quickly produce optics for their long-delayed NuSTAR X-ray telescope. So the scientists as NASA challenged ABTech to develop a multifunctional machine that would act as a grinding lathe, an indexing tool for raster grinding, and an assembly station – all in one. ABTech met the challenge. The [Read More]

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 [Read More]

The application was ultra-precision optical grinding but with a twist. The manufacturer wanted the spindle design to be robust enough to overcome catastrophic crashes that were frequently experienced with their primary supplier. The solution: design a spindle with high accuracy and stiffness at speeds up to 10,000 RPMs, with low air consumption, liquid cooling and [Read More]

Thanks a lot for your help. Your rapid, informative correspondence was invaluable. Hopefully I won't be bothering you with any further questions, but it's good to know you're willing.
