CNC Milling Tolerances and Technical Requirements
Final machining capability depends on material, part dimensions, feature geometry, tool access, wall thickness, inspection method, and production quantity.
| Requirement | Typical Approach | Buyer Guidance |
|---|---|---|
| General Dimensions | Manufactured according to drawing or agreed general tolerance | Mark critical dimensions separately on the 2D drawing |
| Tight Tolerances | Evaluated according to geometry, material, size, and feature location | Only apply tight tolerances to functional dimensions |
| Surface Roughness | Machined finish or specified roughness after process review | Identify sealing, sliding, bearing, or cosmetic surfaces |
| Threads | Internal, external, metric, imperial, or custom thread requirements | Specify thread standard, size, pitch, depth, and fit |
| Geometric Tolerances | Position, flatness, parallelism, perpendicularity, and concentricity | Provide datums and GD&T symbols on the technical drawing |
| Inspection | First-piece, in-process, visual, and final dimensional checks | State required reports and documentation before quotation |
Exact tolerance capability and inspection methods will be confirmed after reviewing your CAD files and technical drawings.
