The Brown & Sharpe 599-750-1 includes two case-hardened steel blocks and two clamps, and is suitable for fine tool room work. The blocks feature squareness for increased usability, accuracy, and measurement consistency. Surfaces are square with each other within .0003”. V-grooves are square and parallel with all surfaces within .0003”, and “V” is 90 degrees + .0000” - .0002”. Corresponding dimensions for each pair are alike within .0003”. Dimensions are 1-1/4” (32 mm) square by 1-5/8” (42-mm) long. Work capacity is approximately 1” to 2-1/2” diameter.
V-blocks are small part work holders. They are held in place with the assistance of a clamp. The grove allows a channel for the clamp to hold down the part being measured or modified.
Brown & Sharpe was founded in 1833, had a major part in setting industrial standards in the United States, and has given its name to several standards, including a tool spindle taper, a worm threadform, and others. Brown & Sharpe was acquired by Hexagon Metrology in 2001, and has since focused on precision measuring equipment and metrology hand tools. The Brown & Sharpe line of coordinate measuring machines (CMMs), optical measuring systems, benchtop measuring machines, and precision hand tools offer consistent, high-quality design, construction, and performance. Brown & Sharpe has manufacturing facilities in North America, Switzerland, and China.
