Cast Iron Surface Plates

Guindy Machine Tools Limited offers Cast Iron Surface Plates that are the products of years of manufacturing experience. These plates are of close-grained cast iron. They are amply ribbed to minimise deflection under load. The composition of the metal, the depth and cross-section of the ribs and the thickness of the plate are designed to conform to the deflection limits specified in IS-2285-2003. Surface plates are manufactured to three grades namely Grade-0, Grade-I and Grade-II, as per the standard stated above. Grade-0 and Grade-I plates are artificially seasoned. They are hand scraped to achieve maximum local deviation from flatness as per standard of any point on the working surface. A special scraping technique is used to achieve a uniform distribution of load bearing point and oil pockets. An average of 15-20 load bearing points after finish scraping is standard. This finish scraping technique ensures that the area of the load bearing points increases after the initial dulling of the high points. This guarantees a long working life, at the required accuracies. Grade-II plates are accurately machined to get the requisite flatness. Standard accessories: plates of sizes 1000 x 630 mm. and smaller, are provided with handle. A wooden cover is provided to protect the working surfaces.
