To ensure the installation accuracy, operational stability and regular service of granite surface plates, this document elaborates on a complete set of standardized installation and commissioning procedures. It mainly covers key points of pre-installation cleaning and precise lifting & positioning, the core method and reading correction for two-way precision leveling along Y and X axes using a digital electronic level or frame level, as well as mandatory requirements for final fitting of auxiliary supports. This procedure guides operators to work in a standard manner and control every detail strictly. It prevents damage to the plate accuracy caused by single-point overload or rough operation, so as to fully extend the service life of the equipment.

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.
