| Feature | Tolerance (ISO 2768-mK) | | :--- | :--- | | 10mm length | ±0.1 mm | | 80mm length | ±0.3 mm | | 200mm length | ±0.5 mm | | Flatness (100mm) | 0.2 mm | | Perpendicularity | 0.2 mm per 10mm | | Angle (<120mm) | ±1° |
Imagine a nominal length of 100 mm .
ISO 2768 is a standard for . It applies to dimensions that are not individually toleranced. It allows manufacturers to use standard workshop precision unless the designer explicitly specifies otherwise. iso 2768 m k
Note: If that dimension were 600 mm, the "m" tolerance would open up to ±0.8 mm.
The standard is divided into two parts, and the shorthand "mK" activates both: | Feature | Tolerance (ISO 2768-mK) | |
Ask any CNC operator about "mK," and they will likely sigh with relief. Here is why:
This is where comes in.
For the designer, it cleans up the drawing. For the machinist, it speeds up production. For the quality manager, it simplifies inspection. When you see that little "mK" in the title block, remember: Someone just saved the company a lot of money.
Could you please clarify which part of the standard you are interested in or if you need a general overview of both? It allows manufacturers to use standard workshop precision
