Surface Flatness Metrology Equipment Precision Granite Surface Plate



Granite Surface Plates are used for precision gauging, inspection, layout and
marking purposes.

They are preferred by Precision Tool Rooms, Engineering Industries and Research

Laboratories because of their following outstanding advantages.

No rust, no corrosion, relatively warp-free, no compensating hump when nicked,

longer wear, smoother action, greater precision, non magnetic, less care after

commissioning, lower co-efficient of thermal expansion and non glaring surface.
