General Tolerance Iso 2768-mk

: Engineers write the code in the title block rather than calculating every margin.

Tight tolerances require specialized tooling, slower machine feeds, and frequent quality inspections. Class "mK" represents a highly achievable, cost-effective standard for standard CNC mills and lathes.

| Aspect | Impact | |--------|--------| | | Lower than tighter classes (e.g., -f), but higher than -c (coarse). | | Inspection | Simple – can be checked with calipers, height gauges, squares. | | Suitable processes | CNC milling, turning, sheet metal bending, 3D printing (with care). | | Not suitable for | High-precision fits (H7/g6), bearing housings, mating parts with clearance <0.05 mm. | general tolerance iso 2768-mk

Represents the tolerance class for linear and angular dimensions . The "m" stands for Medium .

While Part 1 handles standard lengths and angles, Part 2 regulates the geometric relationships of shapes. Part 2 uses three classes: (fine), K (medium), and L (coarse). : Engineers write the code in the title

Permissible Deviations for Linear Dimensions (Except Broken Edges)

An individual tolerance indicated on a specific dimension always takes precedence over the general tolerance. Furthermore, general tolerances do not apply to reference dimensions, auxiliary dimensions, or dimensions already covered by other standards. | Aspect | Impact | |--------|--------| | |
