Cast Iron Surface Plate is available in three grades : Grade-0, I & II, as per IS-2285-2003. They can be made to other standards on request. Grade-I & Grade-II plates are artificially seasoned. Besides, they are hand scraped to achieve maximum local deviation from flatness as per standard at any point on the working surface.
Furthermore, a special scraping technique is used to achieve a uniform distribution of load bearing point and oil pockets. As a result an average of 15-20% load bearing points after finish scraping is standard. Consequently, this finish scraping technique ensures that the area of the load bearing points increases after the initial dulling of the high points. For that reason it guarantees a long working life, at the required accuracies. Grade-II plates are accurately machined to get the requisite flatness.
