Granite offers superior thermal stability, is non-magnetic, and resists corrosion. Its higher density also dampens industrial vibrations much more effectively than steel, leading to higher measurement repeatability.
Our tools are crafted from 00-grade granite, providing a precision accuracy of 0.002mm and flatness tolerances as tight as ±0.0015mm for our 100x150mm models.
While all precision tools benefit from periodic checks, granite's extreme hardness and stability mean it requires significantly less frequent calibration than metal tools, which are prone to warping and wear.
Yes, we offer OEM and ODM support. This includes custom dimensions (from 100x150mm up to 600x400mm) and specialized features like V-grooves for cylindrical part measurement.
Steel expands significantly with temperature changes, causing "thermal drift." Granite's linear expansion is about 10 times lower, ensuring your measurements remain accurate even in fluctuating workshop environments.
Aerospace, semiconductor, automotive die-casting, and optical instrument manufacturing benefit most, as these sectors require ultra-flat surfaces and extreme stability to ensure product safety and performance.
