Industrial Granite Surface Plates

We are into manufacturing, supplying and servicing of Granite Surface Plates to Grade '0' accuracy as per IS 7327-2003. These plates are preferred for the inspection and layout making purposes. These surface plate make an ideal base for mounting sophisticated mechanical, electronic and optical gauging systems.We provide fabricated stand with adjustable leveling screws on request by our clients. The overall working height of surface plates with stand and leveling screw will be 900 MM (approx) from floor level

• Closed grained & uniform texture.
• Very hard, high wear resistance & extreme rigidity. .
• Outstanding dimensional stability.
• Top surface lapped smooth & flat.
• Inspected by electronic level, precision level & auto collimator traceable to NABL.
• Least subjected to internal stresses

Accuracy

Rigorous quality control inspection is carried out at all stages and final inspection is carried out with Electronic Level calibrated by an NABL accredited lab at regular intervals.

Material

Granite Surface Plates are made from select granite with uniform distribution of light and dark constituents. Granite used for surface plates should have the following physical properties.

Basis of Tolerances

• The values specified in table 1 are based on the following formula
• T = C1L + C2 Where
• T is the tolerance on deviation from
• flatness overall, in micrometres;
• L : is the nominal length of the diagonal of the plate rounded
• up to the next 100 mm;
• C1 and C2 are constants for the grade of plate and are given in table 1
