The cast iron platform manufactured according to the national GB7947-1999 standard. Flat accuracy class 0, 1, 2, 3, level and fine plane. 

 Marble measuring mineral composition for the escape of stone, plagioclase, minor olivine, biotite, and trace amounts of magnetite. 

 Straight measuring the characteristics of high precision, good stability, ease of maintenance. 

 Cast iron table in the wear and tear, you can repair scratch again resume its accuracy. The cast iron table can be used coloring method to test the part flatness, has the advantages of accurate, intuitive, and convenient. Promote table after scraping the cast iron work table, the workpiece is relatively smooth, non-astringent feel to facilitate the measurement, to ensure the accuracy of measurement. Cast iron plate cast iron quality and heat treatment have a greater impact on the quality of flat-panel performance: or face deformation due to the remnants of a large internal stress; accuracy can not keep or wear and tear due to intolerance; not value small rough or difficult due to scrapers degrees. The use of cast iron table should be noted that the choice of cast iron materials, aging treatment and other methods to eliminate the residual stress of the cast iron plate. Plugs ring gauge is a precision measuring instrument used to measure the size of workpiece.
