The Z-axis electric hand pulse metallographic measurement microscope newly promoted by our company uses a professional customized high-precision subdivision pulse metallographic measurement motor. By setting multiple pulse subdivision quantities and accurate adjustment on the mechanism, it can achieve fast, medium, and slow three speed regulation to control the up and down movement of the Z-axis optical lens
