Granite test platforms provide outstanding accuracy and stability, making them essential in modern precision engineering and manufacturing. In recent years, their usage has grown rapidly, with granite platforms gradually replacing traditional cast iron gauges. The unique stone material offers excellent adaptability to workshop environments and ensures long-term dimensional stability. This directly improves the accuracy of machining, inspection, and the overall quality of finished products.
The hardness of granite test platforms is comparable to high-grade tempered steel, while their surface precision often surpasses other materials. Manufactured from carefully selected natural black granite, these platforms are finely machined and hand-polished to achieve high flatness and excellent stability.
Key Features & Advantages
-
High Stability – No deformation, high hardness, and strong wear resistance. The dense structure prevents particle shedding and ensures a burr-free, smooth surface.
-
Long Service Life – Natural granite undergoes long-term aging, eliminating internal stress. This ensures durability, minimal thermal expansion, and lasting precision.
-
Corrosion & Rust Resistance – Resistant to acids, alkalis, rust, and moisture. No oiling is required, making maintenance simple and cost-effective.
-
Non-Magnetic & Electrically Insulating – Ensures smooth, accurate measurements without magnetic interference. Ideal for sensitive testing environments.
-
Excellent Temperature Performance – Maintains accuracy at room temperature, with very low linear expansion and deformation resistance.
-
Scratch & Dust Resistance – Surface remains smooth, easy to clean, and unaffected by workshop conditions.
-
Precision Reference Tool – Perfect for inspecting instruments, precision tools, and mechanical parts where traditional cast iron gauges cannot achieve the same level of accuracy.
Applications
Granite test platforms are widely used in metrology laboratories, manufacturing workshops, and precision engineering industries. They serve as reference bases for measuring instruments, precision tooling inspection, mechanical part calibration, and high-accuracy quality control.
