2026-05-15 Granite precision inspection platforms serve as the core reference equipment for precision inspection, mold processing and metrology laboratories. They feature high accuracy and excellent stability, yet the material is highly brittle and sensitive to temperature, humidity and impact. Based on the practical experience of EAST STAR Precision Instrument, this article summarizes a complete and practical maintenance specification for granite platforms. It elaborates the entire process including daily cleaning, standardized operation, environmental control, regular verification and calibration, emergency fault handling, as well as handling and storage guidelines. It helps enterprises implement standardized equipment maintenance, prevent precision drift and surface damage, effectively extend the service life of granite precision inspection platforms, and reduce equipment operation and maintenance costs.
