Frequently Asked Questions About Precision Granite Components
Common questions about component types, accuracy grades and supplier selection to help you define your requirements faster.
How to choose a precision granite components supplier?
Focus on whether the supplier has the right equipment for your component: large-scale grinding machines, temperature-controlled inspection rooms, Grade 00 / Grade 000 machining experience, relevant industry cases and inspection report capability. AccuStone filters manufacturers based on your size, accuracy, material and lead time.
What is the difference between Grade 00 and Grade 000 granite plates?
Both are high-accuracy grades; the lower the number, the tighter the tolerance. Grade 00 granite surface plates are commonly used for CMMs and precision inspection. Grade 000 plates are used for semiconductor equipment and air-bearing stages where thermal stability and flatness are most critical.
What parameters matter when buying granite surface plates?
When buying granite surface plates, first confirm that the granite surface plate supplier has the right size capacity and inspection capability. Key parameters include component type, size range, accuracy grade (000/00/0/1), flatness, surface roughness Ra, material (such as Jinan Qing or Indian black granite), inspection requirements (factory report / third-party calibration / temperature-controlled inspection) and lead time.
What is the difference between air-bearing stages and standard granite platforms?
Air-bearing stages demand tighter flatness, roughness and precision air-bearing hole patterns, typically requiring Ra≤0.2 μm mating surfaces. Standard granite platforms emphasize overall flatness and long-term stability, and are often used as inspection or assembly reference surfaces.
