Instrument (Machine) Shop

Specializing in the manufacture of experimental research and prototype apparatuses, the Physics Instrument Shop is fully equipped to handle most machining, inspection, fabrication, and assembly tasks.

Our highly skilled Instrument Makers have extensive experience machining all conventional materials, exotic alloys, rare-earth metals, plastics, composites, and some ceramics.

Design

Equipped with the latest CAD/CAM software, the Physics Machine Shop can reverse engineer and design from sample parts or rudimentary instructions. 

Using SolidWorks and Unigraphics, Instrument Makers often design devices from hand-drawn sketches and recommend the proper engineering and materials for the application.
