Precision Granite Tri Square Ruler
1. The ultimate "physical gauge" for extreme perpendicularity: In the geometric error compensation of CMMs, the granite triangular gauge is the ultimate standard for defining the perpendicularity of the X-Y-Z axes.
2. The "temperature drift nemesis" of homogeneous materials:As the main structure of CMM is mostly made of granite, the use of granite triangles as accessories has a natural advantage.
3. The "quality inspector" of straightness and running trajectory: It is used to detect the straightness error of machine tool guideways throughout the entire stroke.
4. Weight-reducing design, protecting the precision surface: Triangles specifically designed for CMMs usually feature scientifically distributed weight-reducing holes.

1. Black granite with uniform texture, low internal stress, no deformation from temperature/humidity changes; Mohs hardness 6-7, wear/scratch resistant, high precision long-lasting.
2. Low expansion coefficient, better dimensional stability under temperature fluctuation, more reliable calibration results than metal gauges.
3. Grade AA precision grinding, micron-level flatness/verticality of 90° working surface; non-magnetic, corrosion-resistant, no sensor interference, no metal chip adhesion.
4. Single piece for multi-axis verticality calibration, reducing cumulative error from gauge replacement; large size with lightening holes for easy handling and lower operation intensity.
We use various techniques during this process:
● Optical measurements with autocollimators
● Laser interferometers and laser trackers
● Electronic inclination levels (precision spirit levels)
1. Documents together with products: Inspection reports + Calibration reports(measuring devices) + Quality Certificate + Invoice + Packing List + Contract + Bill of Lading(or AWB).
2. Special Export Plywood Case: Export fumigation-free wooden box.
