Product Application:
Mainly used to measure parallel and equal altitude of precision instrument, precision tool, mechanical component in modern industry and scientific research institutes.
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)
