Inspection surface plate

Granite flat plate is a benchmark measuring tool made of stone material, which is an ideal benchmark for the inspection of instruments, tools, and mechanical parts. Especially in terms of measurement, due to its characteristics, cast iron plates pale in comparison. Granite is made from underground rock layers and has undergone billions of years of natural aging, resulting in an extremely stable shape without worrying about deformation due to conventional temperature differences.

Advantages

Granite material is processed mechanically and finely ground by hand. Black luster, uniform structure and texture, good stability. High intensity. And it has the advantages of no rust, no magnetization, and good stability. Can maintain stability under heavy loads and normal temperatures.

Granite flat plate, granite flat plate, granite inspection flat plate, and instrument platform are made of "Jinan green" stone material through mechanical processing and manual precision grinding. Black luster, structure, uniform texture, good stability, high strength, can be maintained under heavy load and general temperature, and has the advantages of non rusting, non magnetization, and non deformation Granite slabs are suitable for measuring tools in mechanical factories.

During the production process of granite slabs, there may be some theoretical weight errors, but it should be noted whether the production errors of granite slabs affect their normal use. The design of general granite slabs should take into account the errors in mechanical processing and casting. The weight error of granite slabs should generally not exceed 10%. When it exceeds 10%, we need to further evaluate and inspect the quality of the granite slabs to determine whether they can be put into normal use.
