AA GRADE 2-LEDGE GRANITE SURFACE PLATES

DIMENSIONAL STABILITY

AA-Grade Granite Surface Plates with 2-Ledges are high-precision flat surfaces used in metrology, inspection, and machining applications. These plates are made of high-quality granite, which is a natural stone known for its excellent stability, stiffness, and wear resistance.

The term "2-Ledges" refers to the fact that these surface plates have raised edges or lips along two opposite sides of the plate. These ledges provide a secure and stable platform for measuring and inspecting smaller workpieces, and are often used for clamping workpieces to the granite.

AA-Grade Granite Surface Plates with 2-Ledges are manufactured to strict standards and undergo rigorous quality control processes to ensure that they meet the highest level of accuracy and flatness. The term "AA-Grade" refers to the highest level of accuracy, which is achieved by lapping the surface to within 5 microns over the entire surface area.

These surface plates are typically used as reference surfaces for precision measurement instruments such as micrometers, height gauges, and dial indicators. They can also be used as a flat surface for marking out and inspecting machined parts.

AA-Grade Granite Surface Plates with 2-Ledges are available in a range of sizes, from small handheld plates to large floor-mounted plates that can weigh several tons. They are often preferred over other materials such as steel or cast iron due to their superior stability and resistance to wear and corrosion.
