Non-magnetic And Non-conductive 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:
A.The granite is after a long-term natural aging, the
organizational structure is uniform, the expansion coefficient is
small, the internal stress completely disappeared, as a result of
which the precision is very high.
B.Good rigidity, high hardness, strong wear resistance.
C.Not afraid of acid and alkali corrosion, will not rust; do not
need oiling, easy to maintain, long service life.
D. Will not scratch, will not limited by the constant temperature
conditions, and can maintain the measurement precision at room
temperature.
E.Will not be magnetized, and can move smoothly while measuring, no
tight feeling, free of the affect of moisture, good flatness

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)
