Brown & Sharpe
Brown & Sharpe is a division of Hexagon Metrology, Inc., a multinational corporation focused mainly on metrological tools and technology. During the 19th and 20th centuries, Brown & Sharpe was one of the best-known and most influential machine tool builders and was a leading manufacturer of instruments for machinists (such as micrometers and indicators). Its reputation and influence were such that its name is often considered to be inseparably paired with certain industrial standards that it helped establish, including:
The American wire gauge (AWG) standards for wire;
The Brown & Sharpe taper in machine tool spindle tapers; and
The Brown & Sharpe worm threadform for worm gears.
Since being acquired by Hexagon Metrology in 2001, Brown and Sharpe has concentrated exclusively on metrology equipment.
