China are machinery for the production of cast iron bench in the use of wear and tear, can be re-repair scratch to resume its accuracy. So that users can greatly reduce the cost of the work, energy saving and environmental protection. 
 Cast iron table with the flatness of the test part of the coloring method 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 bench cast iron quality and quality of heat treatment tablet using performance will produce a relatively large impact. 
 Something waiting to face deformation due to the remnants of a large internal stress, or wear and tear so that the accuracy can not keep due to impatience, or a small value of the roughness due to scraping the difficulties are not. Therefore use the cast iron table should be noted that the choice of cast iron materials, in order to guarantee the quality of the cast iron plate, precision, and durability such as the aging treatment and other methods to eliminate the residual stress of the cast iron bench. Ensure the interests of its clients.
