Iso 2768 M K [BEST]

What is ISO 2768? | CNC Machining Tolerance Standards - Fictiv

Permissible deviations (±) in millimeters based on the nominal size of the feature: Nominal Length Range (mm) Tolerance (± mm) Over 3 to 6 Over 6 to 30 Over 30 to 120 Over 120 to 400 Over 400 to 1,000 Over 1,000 to 2,000 Over 2,000 to 4,000 Angular Dimensions (Class m) iso 2768 m k

Note: If that dimension were 600 mm, the "m" tolerance would open up to ±0.8 mm. What is ISO 2768

ISO 2768-mK is a safety net, not a straitjacket. If a critical hole requires a tolerance of H7 (±0.015mm), you must call that out directly on the dimension. The general "mK" tolerance applies only to dimensions without individual tolerance annotations. 000 Over 1
