CNC Turning Tolerances and Specifications
Final capability depends on material, diameter, length, geometry, wall thickness, feature location, surface finish and inspection requirements.
| Requirement | Typical Approach | Buyer Guidance |
|---|---|---|
| General Dimensions | Produced to drawing or agreed general tolerance | Mark functional dimensions separately |
| Diameter Tolerances | Evaluated according to material, size and fit | Identify bearing, sealing and mating diameters |
| Concentricity and Runout | Controlled through datum and setup planning | Clearly define datum surfaces and inspection method |
| Threads | Metric, imperial and custom thread requirements | Specify standard, size, pitch, depth and fit |
| Surface Roughness | Machined finish or specified roughness after review | Identify sliding, sealing and cosmetic surfaces |
| Inspection | First-piece, in-process and final dimensional checks | State required reports before quotation |
