Granite Measuring Plate Machine Base
Granite Machine Base for Glass Precision Engraving Machine is made by Black Granite with
density of 3050kg/m3. Granite machine base can offer ultra-high operation precision of 0.001
um(flatness, straightness, parallelism, perpendicular). Metal Machine base can not keep high
precision all the time. And temperature and humidity can affect the precision of metal machine
bed very easily.
