Cubes & V-Blocks

Precision granite cubes are used for alignment and measuring parallelism and perpendicularity of machining centers or coordinate measuring machines. Our cubes are finished flat, square and parallel on all six sides. Available in two grades: Grade AA (.000025”/6”) and Grade A (.000050”/6”).

V-blocks are ideal for supporting or holding cylindrical pieces during manufacturing or inspection. They are provided in matched pairs and have five finished faces. V-blocks have a nominal 90-degree “V”, centered with and parallel to the bottom and two sides and square to the ends. V-blocks come in either laboratory grade AA (+/- .000050” per 6”) or inspection grade A (+/- .000100” per 6”).
