Experience precision and accuracy with our Luthra Granite Surface Plates. Crafted with high quality granite, our surface plates are designed to provide long-term durability. Ideal for inspecting and measuring workpieces, these granite plates offer a flat, solid surface that is resistant to thermal expansion and contraction.Granite Surface Plates are manufactured using natural black granite stone, quarried from earth in its natural form. These precision granite surface plates are precision lapped to high standards of flatness to achieve accuracy and are used as bases for mounting sophisticated mechanical, electronic and optical gauging systems. Our quality inspectors and engineers put a strict vigilance at all the stages of the production procedure to ensure high quality surface plates. SPECIFICATIONS:FLATNESS TOLERANCE IN µm FOR ACCURACY GRADEAS PER IS 7327-2003  SIZE (in mm) GR “0” 250 x 250 3.5 300 x 300 3.5 400 x 400 4.5 630x 400 5.0 630 x 630 x 80 5.0 1000 x 630 x 150 6.0 1000 x 1000 x 150 7.0 1200 x 900 x 150 7.0 1600 x 1000 x 200 8.0 2000 x 1000 x 200 9.5 *Other sizes on request Some of the unique features of our granite surface plates are: Uniformity In Hardness Accurate Under Load Conditions Vibration Absorbent Easy To Clean Rust-Proof, Non-Corrosive Lower Coeffficient of Thermal Expansion  Warp Resistant Low Porosity Non-Abrasive Non-Magnetic Other Details: These advantages make black granite surface plates inherently stable and unmatched against any other material. These surface plates are supplied with a calibration certificate traceable to National Physical Laboratory (NPL, Govt of India ) New Delhi. We also have our In-House NABL accredited Calibration Lab. Rexin covers are provided with each surface plate for protection of top surface.  We provide fabricated stand with leveling screws on request by our clients. The overall working height of surface plate with stand and leveling screw will be 900 mm (approx) from floor level.Option for vibration pads to control vibration is also available. We also provide T-slots, threaded inserts as per customer's  requirement.
