Weihao cast iron surface plate are the result of years experience as a manufacturer both in foundry technology and metrology. These plates are of HT200-300. They are amply ribbed to minimize 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 National Standard. Weihao Surface plates are manufactured to three grades namely Grade-0, Grade-I & Grade-II, as per the standard stated above. They can be made to other standards on request. Grade-I & Grade-II plates are artificially seasoned. They are hand scraped to achieve maximum local deviation from flatness as per standard at 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.

We offer a qualitative range of precision Cast Iron Surface Plate. These cast iron surface plates provide an accurate reference or datum plane for precision gauging, marking, inspection and tooling setup. The meticulous manufacturing processes that are carried out at our premises make these C.I surface plate apt for machine shops, quality control and standard rooms. Our precision cast iron surface plates are used in the application where strict accuracy is required hence, these plates are appropriate for high precision work and are ideal for blue matching. Our team of qualified engineers carries out rigorous quality control inspection to test these surface plates as National Standard for flatness ,repeatability, durability etc. The final inspection of surface plate is undertaken by a high precision computerized electronic level make Cast Iron Surface Plate.

OPTIONAL ACCESSORIES

Fabricated heavy angle iron stands, with required leveling screws, are offered for all plates to provide convenient working height. Cast iron column floor stands each with a leveling screw and nut are also offered as an option as : A set of 5 & 3 for leveling and 2 for support for sizes below 2000 x 1000mm plate and a set of 7 & 5 for leveling and two for support, for sizes above 2000 x 1000 mm.

To meet special requirements we offer on request custom size cast iron surface plates above 4000x1200 mm as a joint surface plate, with fabricated heavy angle iron stands and bed plates with special cast iron floor stands.
