precision granite master squares are used for checking the X-Y-Z axes on CNC machine tools and CMM's

 

Made of Fine Black, Metrology Grade Granite, 6-Face Master Squares may also be used on any work that requires the checking of squareness or parallelism. Master squares have 6 finished faces . One large square face is finished flat and perpendicular to the four sides, which are parallel and perpendicular to one another.

 

The working surfaces are ground and lapped parallel to each other, remaining sides are polished. They are provided with through-holes for weight reduction and ease of handling. GMT 6-Face Granite Master Squares are ideal for accurately checking the X-Y-Z axes on CNC machine tools and coordinate measuring machines.

 

 

With the square in the horizontal position, the X and Y axes can be checked for 90° squareness. With the square in the vertical position, tracing along the vertical edge of the square can check the perpendicularity of the Z axis. By tracing along the top edge of the square while in the vertical position, it will check parallelism to the table in the X and Y axes can be checked.
