granite tri square
In laboratory metrology, granite triangular plates serve as primary reference standards. Comparative measurement—where dimensional deviations are evaluated relative to a stable, high-stability artifact—constitutes the foundational principle of precision metrology; in this context, granite plates offer superior dimensional stability, thermal inertia, and surface integrity compared with metallic measuring tools.

Granite Parallels
The fundamental principle underlying parallelism error measurement is to utilize the high-precision reference plane of a granite parallelism gauge as an ideal datum surface, and then quantify the maximum deviation—typically expressed as the distance between two parallel planes—between the workpiece surface and this datum surface.

Ultra-Precision Granite Machine Base with Linear Guide Assembly
Scientific Insight: Why Granite Ensures Long-Term Accuracy
Unlike cast iron, granite contains no internal casting stress. Metal structures gradually deform due to stress release, temperature fluctuation, and oxidation. -
Granite Surface Plate with stand
In precision inspection and measurement, granite surface plates—typically mounted on adjustable, vibration-damped stands—are widely recognized as the foundational reference standard in industrial metrology. Far exceeding the functional scope of ordinary workbenches, they serve as stable, thermally stable, and geometrically accurate reference planes for calibration, alignment, and high-accuracy dimensional verification.
