![]() ![]() Your fH is really tight but if the CNC guys can hold them then that's great! ![]() DIN ISO 2768 mk tolerances I have some drawings from Germany that use the DIN 2768 tolerances and I am having trouble understanding it correctly. If you send your metric print to a US shop and they don't know how to read the metric print, find another shop! We had to do that about 3 times because one didn't know how to read Ra surface finishes, another one didn't like that some metric tolerances went down to. I do not have a full copy of the DIN but I do have some notes and a brief discription of how the tolerances are supposed to work but I still dont quite understand it. STANDARD ISO 27681 General tolerances for linear and angular dimensions. ISO 2768 has defined general tolerance for: Linear Dimensions Angular Dimension External Radius and Chamfer height Geometric Tolerance such as straightness, flatness, perpendicularity, symmetry and runout. Iso 2768 mk tolerances iso#Ġ001in and they said they couldn't hold that. And ISO-2768 standard defines the values of general tolerance. ![]()
