High Precision 800x500MM Black Granite Surface Plate Calibration
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.
Salient Features :
Made from close-grained Granite having uniform color and texture
having hardness between 5.6 to 7 on Moh's scale, sound and free
from flaws fissures and large inclusions of softer minerals.
Made generally as per GB117-2015. Also available on request
conforming to DIN-876-1972, BS-817-1988, JIS -B-7513 and US Federal
specification GGG-P-463-C.
metallic threaded inserts, metallic T-slots, Plates with two or
four ledges also can be supplied against specific request at extra
cost.
Rexine cover provided for top working surface with each Plate.
steel stand with leveling screws are available on request at extra
cost.
Granite Lapping Plates square and rectangular available on request.
Also available in Grade 00 as per DIN 876.
Sizes offered from 200x300mm to 8000x2000mm
Other sizes are also offered on request.

We are able to manufacture the Granite Surface Plate with the good
and stable flatness according to standard of DIN/JIS/GB.
Our granite surface plate refers to the advanced standards of the leading countries, and its flatness tolerance is in accordance with the JB/T 7975-1999 Surface Plate:
Grade 000 =1x(1+d/1000)/μm
Grade 00 =2x(1+d/1000)/μm
Grade 0 =4x(1+d/1000)/μm
Grade 1 =8x(1+d/1000)/μm
(d is the length of the diagonal)
