Granite Inspection Surface Plate

Product features:

This granite inspection surface plate adopts integral fine grinding and polishing processing, with no splicing joints on the working surface, ensuring the consistency and accuracy of the entire platform flatness. Each plate has passed strict flatness calibration, reaching Grade 00/0 accuracy standard, with a flatness error of less than 0.5μm per meter for Grade 00 products. The surface roughness reaches Ra≤0.05μm, which can improve the positioning accuracy of workpieces and reduce the wear of the workpiece during processing. It has excellent thermal stability, with a deformation of only 0.3μm per meter per 10℃, ensuring accurate measurement results in different temperature environments. The product has a dense and smooth surface, which is not easy to adsorb dust and oil stains, and can be quickly cleaned with industrial cleaning agents, reducing maintenance costs. It also has excellent load-bearing capacity, up to 800kg per square meter, suitable for placing large and medium-sized workpieces for processing and testing.
