Lab Precision Black Granite Calibration Surface Plate Testing Table

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.

Proportion,2970-3070kg/m3

Compression strength,245-254kg/mm2

Flexible grinding capacity,1.27-1.47N/mm2

Coefficient of linear expansion,4.6×1-6°C

Water absorption 0.13%

Shore hardness HS, more than 70.

Precision has  00, 0, 1 grade.

• Precision Surface Plate using granite gabbro
• precision surface plate It is very  and superior in wear resistance. secular distortion is minimal, it does not rust, as well as other advantages.
• precision surface plate In addition to standard products, we also manufacture with special measurements, hole drilling, screw machining, etc.
• We can also make special mounts using square pipe.
