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)
