Granite Calibration Flatness Lapping Stone Flat Surface Plate Table
Granite surface plate is a precise benchmark measuring tool. It is the ideal datum for instruments, precision tools and mechanical parts. Especially for high-precision measurement, because of its unique characteristics, cast iron plate is dwarfed. Granite surface plate, granite inspection plate, granite instrument and granite working platform use high quality natural granite by mechanical processing and manual fine grinding. It has black gloss, fine structure, uniform texture and good stability. High strength and high hardness. It can keep stable at heavy load and general temperature. It also has the advantages of no rust, acid and alkali resistance, wear resistance, no magnetization, constant wear resistance and good wear resistance. Granite plate is suitable for measuring flatness and roughness in machinery factories and laboratories. We can also produce the granite Plate as your request and provide technical support for you. We would like to introduce our company and hardware products to you, and build long term business cooperation with you sincerely in future.
