The calculation formula is as follows:
Parallel precision = Flatness precision * 2
Using high-quality granite slabs with precision referenced to German national standards:
-Right angle degrees on two sides according to DIN875 standard.
-Flatness precision according to DIN876 standard.
These precision tools are essential for precision inspection and laboratory work. They are made from low moisture content, non-weathered rock, and high-quality granite stone, and can be customized according to customer requirements.
