Precision measuring tool calibration requires accurate auxiliary tools, and this rotating stage fully meets the requirements. Its tabletop, with a diameter of ø25 mm (25 mm in diameter), can hold small measuring tools; it is made of aluminum alloy, featuring a stable structure that is not easily deformed, and its surface has undergone black anodization treatment, providing excellent wear resistance. This rotating stage has a load capacity of 29.4 N, which can provide stable support for measuring tools; through 360° rotation, the angle of the measuring tools can be flexibly adjusted, facilitating the calibration equipment to conduct comprehensive accuracy detection of the measuring tools and ensuring the calibration results are accurate and reliable.
