The marble slab is a kind of flatness of the marble used to test the workpiece measuring, how much of the marble slab with the workpiece point of contact determines the processing cost of the marble slab. Applicable to industrial production and laboratory measurements. 


 The main features of the marble slab the accuracy and stability, easy maintenance, because the marble by the long-term natural aging, the internal stress completely disappeared, material stability, not deformed; dense marble slab organizational structure, smooth wear surface roughness values; acid resistance, alkali, corrosion-resistant, anti-magnetic; not damp rust, use, easy to maintain; face by collision or scratched, it will only pits, does not produce embossed glitches, affect the linear expansion coefficient of the measurement accuracy , little affected by temperature. 


 The main drawback of the marble slab is: You can not put too much hit, beat, high humidity, deformation, moisture absorption is not high, need to dry environment.
