Granite inspection platforms are precision measuring tools made of stone. They are ideal reference surfaces for testing instruments, precision tools, and mechanical components. Granite platforms are particularly suited for high-precision measurements. Granite is sourced from underground rock layers and, after millions of years of natural aging, has an extremely stable form, eliminating the risk of deformation due to temperature fluctuations. Granite platforms are carefully selected and subjected to rigorous physical testing, resulting in fine-grained, hard texture. Since granite is a non-metallic material, it exhibits magnetic properties and exhibits no plastic deformation. The high hardness of granite platforms ensures excellent precision retention.
Plate accuracy grades include 00, 0, 1, 2, and 3, as well as precision planing. Plates are available in ribbed and box-type designs, with rectangular, square, or round working surfaces. Scraping is used to process V-, T-, and U-shaped grooves, as well as round and elongated holes. Each material comes with a corresponding test report. This report includes a cost analysis for the sample and a determination of radiation exposure. It also includes information on water absorption and compressive strength. A mine normally produces a single type of material, which doesn’t change with age.
During manual grinding, friction between diamonds and the mica within the granite creates a black substance, turning the gray marble black. This is why granite platforms are naturally gray but black after processing. Users are increasingly demanding the quality of precision granite platforms, which can be used to inspect high-precision workpieces. Granite platforms are most commonly used in factory quality inspections, serving as the final checkpoint for product quality. This demonstrates the importance of granite platforms as precision measuring tools.
Granite test platforms are precision reference measuring tools made from natural stone. They are ideal reference surfaces for inspecting instruments, precision tools, and mechanical parts. Especially for high-precision measurements, their unique properties make cast iron flatbeds pale in comparison.
