Granite Tri SquareGMT GRANITE TRI SQUARE

Firstly, GMT Granite Tri Square finds application for checking the X-Y-Z axes on CNC machines, milling machines, CMM’s. Furthermore, it’s made of Indian Black Granite and provided with through-holes for weight reduction and ease of handling. Therefore all 6 sides are lapped to maintain flatness, squareness and parallelism.

Consequently, GMT Granite Tri-Squares provide an excellent, economical way for accurately checking the X-Y-Z axes. Hence, it finds application on CNC machines, milling machines and coordinate measuring machines. Besides, GMT Tri-squares finds uses in the same manner that steel squares for the direct checking of straightness and squareness.

Place it in the horizontal position (the X and Y axes) to check for 90° squareness.  Furthermore, with the square in the vertical position, tracing along the vertical edge of the square can check the perpendicularity of the Z axis. Tri-Squares have 6 finished faces.
