ABTech Manufacturing

ABTech Manufacturing makes air bearing motion parts and measurement systems from its headquarters in Fitzwilliam, New Hampshire. It builds products for jobs that need extremely tight accuracy.

The company says its customers need parts with accuracy of one millionth of an inch, near absolute repeatability and no-contact parts that do not wear. It takes on custom engineering jobs that others will not and builds to the most precise and difficult specifications.

Its precision motion components are rotary tables, spindles and linear stages. Its measurement products include MicroForm roundness gages and MicroTIR gages, which are made to suit each application. ABTech also builds turbine engine assembly systems, including systems for GE engines and the FormStack and FormCheck lines. It also designs specialty solutions for individual customer needs.

All products are designed, made and tested only by ABTech at its New Hampshire plant. The company calls this its Pride in Precision approach and sells under a Made in the USA mark.

ABTech serves aerospace, automotive, aviation, energy, land and marine, manufacturing, optics and semiconductor customers around the world. One user, Vertex Optics, reports that it uses two ABTech air bearing spindles for precision assembly and final metrology. A Princeton University researcher thanked the company for remote technical support on a system installed at the South Pole.

The company publishes whitepapers, technical papers, videos and a blog. Topics include the limits of ultra-precision rotary tables, single point diamond turning with air bearings and optical machine tool design. It offers a free consultation and a quote service.
