3-Face Tri-Squares

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.

Features

  • Three-Face Granite Tri-Squares provide an excellent, economical way for accurately checking the X-Y-Z axes on CNC machine tools and coordinate measuring machines.
  • Lying 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.
  • Granite tri-squares may also be used in the same manner that steel squares would be used for the direct checking of squareness and straightness.
  • Tri-Squares have 3 finished faces the bottom surface, the tall edge perpendicular to the bottom and one large triangular face, perpendicular to the other 2 faces.
  • Custom sizes can be quoted upon request.
  • Storage and Travel Cases are available at an additional charge.
