Indian Stone (Indian Black Granite for Precision Measuring Tools / Imported Gabbro) Main CompositionThe Indian Stone used in the industry for marble/granite inspection platforms and CMM bases is essentially a fine-grained gabbro to diorite, often classified as a dark-colored basic intrusive rock. I. Main Mineral Composition (Percentage)Plagioclase: 55%–65% (Primary)Calcium-sodium plagioclase, tabular crystals, determining the stone’s…
The core differences among these four types of stone lie in their origin, appearance, density/stablity, price, and application: Jinan Green offers the highest precision but is scarce and expensive; Indian Stone performs similarly to Jinan Green but is costly due to importation; ZhStone offers good value for money but fades easily when dyed; Northeast Stone…
🌟 I. Core Advantages: The “Black Tech” of Natural Stone
In the race for precision at the micron and even nanometer level, any minute thermal deformation, vibration, or stress can become the key determinant of success or failure. High-end manufacturing, precision measurement, and cutting-edge scientific research are all seeking an absolutely stable and reliable reference plane. It is precisely under this extreme demand that precision…
