Flatness Gauge 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.
Advantages:
1. After aging for a long time, the internal stress of natural granite disappears, the material is stable, and no deformationoccurs.
2. No damp rust, easy to use and maintain.
3.The linear expansion coefficient is less affected by temperature.
4.Artificial grinding of working surface, no burr, high precision.
5. If you need T-slot or hole, we can produce according to your drawing.
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.
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)
