摘要

In the last half-century, spindle accuracy specifications have gone from tenths to microns to microinches to nanometers. In the pursuit of precision, the Blockhead air bearing spindle is the gold standard for accuracy and has been the workhorse at Professional Instruments since its inception. "The Blockhead has seen application in a wide variety of fields from basic physics research in the value of the gravitational constant to the fabrication of intraocular lenses for cataract surgery." [1] Understanding the history of the Blockhead and how it came to be requires an understanding of the history of Professional Instruments and how two brothers played a key role in the field of precision engineering.
