Streamlines the design process by using a "default" precision level suitable for the part's function . Summary Table for fK Classes Typical Application Linear/Angular f (Fine) High-precision machining Geometric K (Medium) General mechanical components
As a manufacturer or buyer, what does fK mean for cost and inspection? iso 2768 fk
The tolerance values for ISO 2768 FK vary depending on the dimension range. Here are some examples of tolerance values for different dimension ranges: Streamlines the design process by using a "default"
| Aspect | Implication | |--------|--------------| | | Suitable for standard CNC machining without custom gauges | | Inspection | Use standard calipers (linear) and dial indicators (geometric) | | Cost | Lower than tighter classes (e.g., ISO 2768‑m) | | Risk | Not for press fits, bearing seats, or high-precision alignment | | Drawing note | “General tolerances ISO 2768‑FK” | Here are some examples of tolerance values for
But what exactly does "fK" mean? Why would you choose it over "mK"? And what are the specific numerical limits it imposes on your parts?
