Product Description
This is Starrett's granite tri-square surface plate. Three-Face Granite Tri-Squares provide an excellent, economical way to check X, Y and Z axis alignment on CNCs and CMMs. They can also be used in the same way as a steel square for direct checking of squareness and straightness.
Lying in the horizontal position, the X and Y axis can be checked for 90 degree squareness. With the square in the vertical position, tracing along the vertical edge of the square can check the perpendicularity of the Z axis.
