Our Products
Our product range contains a wide range of Luthra Cast Iron Bed Plate, Cast Iron Lapping Plates and Cast Iron Surface Plates
We manufacture, export and supply pristine Cast Iron Lapping Plates. Fabricated using closed grain graded casting as per IS 210:1993 confirming to Grade FG- 220, these Cast Iron Lapping Plates ensure precision lapping of components of various sizes. These components are lapped using lapping powder of different grits to achieve finish and accuracy. Available in different specifications, our complete assortment of Cast Iron Lapping Plates complies with set industry standards and are quality approved by the authorities. These lapping plates are supplied with calibration certificate traceable to National Physical Laboratory (NPL, Govt of India) New Delhi

These plates are of close grained cast iron. 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 IS 2285 -1963.
Surface plates are manufactured to two tolerance standards. - Grade-I and Grade-II. Grade-I plates are more precise than Grade-II plates. The deviation in flatness for Grade-I and Grade -II plates for sizes upto and including 2000 x 1000 mm are as prescribed in IS 2285-1963.
Grade-1 plates are artificially seasoned.They are hand scraped to achieve maximum local deviation from flatness of 5 microns over any length of 300 mm at any points on the working face , in plates of 630 X 400 mm and larger. Aspecial scraping technique is used to achieve a uniform distribution of load bearing points 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 intial 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.
